This website is now generated using Asciideck (Hugo will use the <a href="https://github.com/ninenines/asciideck/blob/master/scripts/asciidoc">asciidoc</a> script to generate HTML). But a lot of elements are not parsed properly, or are ignored by translator modules. It will take many more documents to get close to the original Asciidoc implementation in terms of features.</p> <p>I wrote this project twice: first as an ugly prototype that generated man pages, and then I rewrote that using a different technique for parsing. I looked at a few different Asciidoc and Markdown implementations and found the Markdown code in Pandoc to be surprisingly readable despite being written in Haskell. I could not fully understand how it worked, but I could follow it based on my knowledge of the syntax.</p> <p>I decided to write small functions that only contain the "happy path" for each possible blocks in an Asciidoc document.

The constraints are reusable functions that can serve as guards against unwanted data, providing convenience in the process.</p> <p>Your handlers will not look like an endless series of calls to get and convert the input data, they will instead be just one call at the beginning followed by the actual application logic, thanks to constraints and maps.</p> -<div class="listingblock"><div class="content"><!-- Generator: GNU source-highlight 3.1.8 +<div class="listingblock"><div class="content"><!-- Generator: GNU source-highlight 3.1.9 by Lorenzo Bettini http://www.lorenzobettini.it http://www.gnu.org/software/src-highlite --> @@ -130,6 +130,10 @@ http://www.gnu.org/software/src-highlite --> + <li><a href="https://ninenines.eu/articles/cowboy-2.7.0/">Cowboy 2.7</a></li> + + + <li><a href="https://ninenines.eu/articles/gun-2.0.0-pre.1/">Gun 2.0 pre-release 1</a></li> diff --git a/articles/dont-let-it-crash/index.html b/articles/dont-let-it-crash/index.html index 1e9e9110..39e5a005 100644 --- a/articles/dont-let-it-crash/index.html +++ b/articles/dont-let-it-crash/index.html @@ -105,6 +105,10 @@ + <li><a href="https://ninenines.eu/articles/cowboy-2.7.0/">Cowboy 2.7</a></li> + + + <li><a href="https://ninenines.eu/articles/gun-2.0.0-pre.1/">Gun 2.0 pre-release 1</a></li> diff --git a/articles/erlang-meetup-10-septembre-2019/index.html b/articles/erlang-meetup-10-septembre-2019/index.html index f394df19..74575492 100644 --- a/articles/erlang-meetup-10-septembre-2019/index.html +++ b/articles/erlang-meetup-10-septembre-2019/index.html @@ -85,6 +85,10 @@ + <li><a href="https://ninenines.eu/articles/cowboy-2.7.0/">Cowboy 2.7</a></li> + + + <li><a href="https://ninenines.eu/articles/gun-2.0.0-pre.1/">Gun 2.0 pre-release 1</a></li> diff --git a/articles/erlang-scalability/index.html b/articles/erlang-scalability/index.html index 92f7030f..b3809ce6 100644 --- a/articles/erlang-scalability/index.html +++ b/articles/erlang-scalability/index.html @@ -117,6 +117,10 @@ + <li><a href="https://ninenines.eu/articles/cowboy-2.7.0/">Cowboy 2.7</a></li> + + + <li><a href="https://ninenines.eu/articles/gun-2.0.0-pre.1/">Gun 2.0 pre-release 1</a></li> diff --git a/articles/erlang-validate-utf8/index.html b/articles/erlang-validate-utf8/index.html index 9fa1529d..4569972f 100644 --- a/articles/erlang-validate-utf8/index.html +++ b/articles/erlang-validate-utf8/index.html @@ -73,7 +73,7 @@ change in the way the code validates UTF-8 data</a> (required for text and close frames as per the spec).</p> <p>When looking into why the permessage-deflate tests in autobahntestsuite were taking such a long time, I found that autobahn is using an adaptation of the algorithm named <a href="http://bjoern.hoehrmann.de/utf-8/decoder/dfa/">Flexible and Economical UTF-8 Decoder</a>.

A few connections are opened and requests +are sent through these connections. Then the web page +is displayed on your screen. Your browser will only +open up to 4 or 8 connections to the server, depending +on your settings. This isn't much. + +But think about it. You are not the only one accessing +the server at the same time. There can be hundreds, if +not thousands, if not millions of connections to the +same server at the same time. + +Even today a lot of systems used in production haven't +solved the C10K problem (ten thousand concurrent connections). +And the ones who did are trying hard to get to the next +step, C100K, and are pretty far from it. + +Erlang meanwhile has no problem handling millions of +connections. At the time of writing there are application +servers written in Erlang that can handle more than two +million connections on a single server in a real production +application, with spare memory and CPU! + +The Web is concurrent, and Erlang is a language designed +for concurrency, so it is a perfect match. + +Of course, various platforms need to scale beyond a few +million connections. This is where Erlang's built-in +distribution mechanisms come in. If one server isn't +enough, add more! Erlang allows you to use the same code +for talking to local processes or to processes in other +parts of your cluster, which means you can scale very +quickly if the need arises. + +The Web has large userbases, and the Erlang platform was +designed to work in a distributed setting, so it is a +perfect match. + +Or is it? Surely you can find solutions to handle that many +concurrent connections with your favorite language... But all +these solutions will break down in the next few years. Why? +Firstly because servers don't get any more powerful, they +instead get a lot more cores and memory. This is only useful +if your application can use them properly, and Erlang is +light-years away from anything else in that area. Secondly, +today your computer and your phone are online, tomorrow your +watch, goggles, bike, car, fridge and tons of other devices +will also connect to various applications on the Internet. + +Only Erlang is prepared to deal with what's coming. + +=== The Web is soft real time + +What does soft real time mean, you ask? It means we want the +operations done as quickly as possible, and in the case of +web applications, it means we want the data propagated fast. + +In comparison, hard real time has a similar meaning, but also +has a hard time constraint, for example an operation needs to +be done in under N milliseconds otherwise the system fails +entirely. + +Users aren't that needy yet, they just want to get access +to their content in a reasonable delay, and they want the +actions they make to register at most a few seconds after +they submitted them, otherwise they'll start worrying about +whether it successfully went through. + +The Web is soft real time because taking longer to perform an +operation would be seen as bad quality of service. + +Erlang is a soft real time system. It will always run +processes fairly, a little at a time, switching to another +process after a while and preventing a single process to +steal resources from all others. This means that Erlang +can guarantee stable low latency of operations. + +Erlang provides the guarantees that the soft real time Web +requires. + +=== The Web is asynchronous + +Long ago, the Web was synchronous because HTTP was synchronous. +You fired a request, and then waited for a response. Not anymore. +It all began when XmlHttpRequest started being used. It allowed +the client to perform asynchronous calls to the server. + +Then Websocket appeared and allowed both the server and the client +to send data to the other endpoint completely asynchronously. The +data is contained within frames and no response is necessary. + +Erlang processes work the same. They send each other data contained +within messages and then continue running without needing a response. +They tend to spend most of their time inactive, waiting for a new +message, and the Erlang VM happily activate them when one is received. + +It is therefore quite easy to imagine Erlang being good at receiving +Websocket frames, which may come in at unpredictable times, pass the +data to the responsible processes which are always ready waiting for +new messages, and perform the operations required by only activating +the required parts of the system. + +The more recent Web technologies, like Websocket of course, but also +HTTP/2.0, are all fully asynchronous protocols. The concept +of requests and responses is retained of course, but anything could +be sent in between, by both the client or the browser, and the +responses could also be received in a completely different order. + +Erlang is by nature asynchronous and really good at it thanks to the +great engineering that has been done in the VM over the years. It's +only natural that it's so good at dealing with the asynchronous Web. + +=== The Web is omnipresent + +The Web has taken a very important part of our lives. We're +connected at all times, when we're on our phone, using our computer, +passing time using a tablet while in the bathroom...

Its features are a perfect match for the requirements of modern Web applications.</p> +<h2 id="_the_web_is_concurrent">The Web is concurrent</h2> +<p>When you access a website there is little concurrency involved. A few connections are opened and requests are sent through these connections. Then the web page is displayed on your screen. Your browser will only open up to 4 or 8 connections to the server, depending on your settings. This isn't much.</p> +<p>But think about it. You are not the only one accessing the server at the same time. There can be hundreds, if not thousands, if not millions of connections to the same server at the same time.</p> +<p>Even today a lot of systems used in production haven't solved the C10K problem (ten thousand concurrent connections). And the ones who did are trying hard to get to the next step, C100K, and are pretty far from it.</p> +<p>Erlang meanwhile has no problem handling millions of connections. At the time of writing there are application servers written in Erlang that can handle more than two million connections on a single server in a real production application, with spare memory and CPU!</p> +<p>The Web is concurrent, and Erlang is a language designed for concurrency, so it is a perfect match.</p> +<p>Of course, various platforms need to scale beyond a few million connections. This is where Erlang's built-in distribution mechanisms come in. If one server isn't enough, add more! Erlang allows you to use the same code for talking to local processes or to processes in other parts of your cluster, which means you can scale very quickly if the need arises.</p> +<p>The Web has large userbases, and the Erlang platform was designed to work in a distributed setting, so it is a perfect match.</p> +<p>Or is it? Surely you can find solutions to handle that many concurrent connections with your favorite language... But all these solutions will break down in the next few years. Why? Firstly because servers don't get any more powerful, they instead get a lot more cores and memory. This is only useful if your application can use them properly, and Erlang is light-years away from anything else in that area. Secondly, today your computer and your phone are online, tomorrow your watch, goggles, bike, car, fridge and tons of other devices will also connect to various applications on the Internet.</p> +<p>Only Erlang is prepared to deal with what's coming.</p> +<h2 id="_the_web_is_soft_real_time">The Web is soft real time</h2> +<p>What does soft real time mean, you ask? It means we want the operations done as quickly as possible, and in the case of web applications, it means we want the data propagated fast.</p> +<p>In comparison, hard real time has a similar meaning, but also has a hard time constraint, for example an operation needs to be done in under N milliseconds otherwise the system fails entirely.</p> +<p>Users aren't that needy yet, they just want to get access to their content in a reasonable delay, and they want the actions they make to register at most a few seconds after they submitted them, otherwise they'll start worrying about whether it successfully went through.</p> +<p>The Web is soft real time because taking longer to perform an operation would be seen as bad quality of service.</p> +<p>Erlang is a soft real time system. It will always run processes fairly, a little at a time, switching to another process after a while and preventing a single process to steal resources from all others. This means that Erlang can guarantee stable low latency of operations.</p> +<p>Erlang provides the guarantees that the soft real time Web requires.</p> +<h2 id="_the_web_is_asynchronous">The Web is asynchronous</h2> +<p>Long ago, the Web was synchronous because HTTP was synchronous. You fired a request, and then waited for a response. Not anymore. It all began when XmlHttpRequest started being used. It allowed the client to perform asynchronous calls to the server.</p> +<p>Then Websocket appeared and allowed both the server and the client to send data to the other endpoint completely asynchronously. The data is contained within frames and no response is necessary.</p> +<p>Erlang processes work the same. They send each other data contained within messages and then continue running without needing a response. They tend to spend most of their time inactive, waiting for a new message, and the Erlang VM happily activate them when one is received.</p> +<p>It is therefore quite easy to imagine Erlang being good at receiving Websocket frames, which may come in at unpredictable times, pass the data to the responsible processes which are always ready waiting for new messages, and perform the operations required by only activating the required parts of the system.</p> +<p>The more recent Web technologies, like Websocket of course, but also HTTP/2.0, are all fully asynchronous protocols. The concept of requests and responses is retained of course, but anything could be sent in between, by both the client or the browser, and the responses could also be received in a completely different order.</p> +<p>Erlang is by nature asynchronous and really good at it thanks to the great engineering that has been done in the VM over the years. It's only natural that it's so good at dealing with the asynchronous Web.</p> +<h2 id="_the_web_is_omnipresent">The Web is omnipresent</h2> +<p>The Web has taken a very important part of our lives. We're connected at all times, when we're on our phone, using our computer, passing time using a tablet while in the bathroom... And this isn't going to slow down, every single device at home or on us will be connected.</p> +<p>All these devices are always connected. And with the number of alternatives to give you access to the content you seek, users tend to not stick around when problems arise.

By default, two middlewares are defined, for the routing and handling of the request, as is detailed in most of this guide.</p> +<p>Middlewares give you complete control over how requests are to be processed. You can add your own middlewares to the mix or completely change the chain of middlewares as needed.</p> +<p>Cowboy will execute all middlewares in the given order, unless one of them decides to stop processing.</p> +<h2 id="_usage">Usage</h2> +<p>Middlewares only need to implement a single callback: <code>execute/2</code>. It is defined in the <code>cowboy_middleware</code> behavior.</p> +<p>This callback has two arguments. The first is the <code>Req</code> object. The second is the environment.</p> +<p>Middlewares can return one of three different values:</p> +<ul><li><code>{ok, Req, Env}</code> to continue the request processing +</li> +<li><code>{suspend, Module, Function, Args}</code> to hibernate +</li> +<li><code>{stop, Req}</code> to stop processing and move on to the next request +</li> +</ul> +<p>Of note is that when hibernating, processing will resume on the given MFA, discarding all previous stacktrace. Make sure you keep the <code>Req</code> and <code>Env</code> in the arguments of this MFA for later use.</p> +<p>If an error happens during middleware processing, Cowboy will not try to send an error back to the socket, the process will just crash. It is up to the middleware to make sure that a reply is sent if something goes wrong.</p> +<h2 id="_configuration">Configuration</h2> +<p>The middleware environment is defined as the <code>env</code> protocol option. In the previous chapters we saw it briefly when we needed to pass the routing information. It is a list of tuples with the first element being an atom and the second any Erlang term.</p> +<p>Two values in the environment are reserved:</p> +<ul><li><code>listener</code> contains the name of the listener +</li> +<li><code>result</code> contains the result of the processing +</li> +</ul> +<p>The <code>listener</code> value is always defined. The <code>result</code> value can be set by any middleware. If set to anything other than <code>ok</code>, Cowboy will not process any subsequent requests on this connection.</p> +<p>The middlewares that come with Cowboy may define or require other environment values to perform.</p> +<p>You can update the environment by calling the <code>cowboy:set_env/3</code> convenience function, adding or replacing a value in the environment.</p> +<h2 id="_routing_middleware">Routing middleware</h2> +<p>The routing middleware requires the <code>dispatch</code> value.

It should be compatible with Ranch 1.0 or above, however +it has not been tested with Ranch versions older than 1.4. + +Cowboy 2.0 is tested on Arch Linux, Ubuntu, FreeBSD, Windows +and OSX. It is tested with every point release (latest patch +release) and also with HiPE on the most recent release. + +Cowboy 2.0 now comes with Erlang.mk templates. + +=== Features added + +* The HTTP/2 protocol is now supported. + +* Cowboy no longer uses only one process per connection. + It now uses one process per connection plus one process + per request by default. This is necessary for HTTP/2. + There might be a slight drop in performance for HTTP/1.1 + connections due to this change. + +* Cowboy internals have largely been reworked in order to + support HTTP/2. This opened the way to stream handlers, + which are a chain of modules that are called whenever + something happens relating to a request/response. + +* The `cowboy_stream_h` stream handler has been added. + It provides most of Cowboy's default behavior. + +* The `cowboy_compress_h` stream handler has been added. + It compresses responses when possible. It's worth noting + that it compresses in more cases than Cowboy 1.0 ever did. + +* Because of the many changes in the internals of Cowboy, + many options have been added or modified. Of note is that + the Websocket options are now given per handler rather + than for the entire listener. + +* Websocket permessage-deflate compression is now supported + via the `compress` option. + +* Static file handlers will now correctly find files found + in '.ez' archives. + +* Constraints have been generalized and are now used not only + in the router but also in some `cowboy_req` functions. Their + interface has also been modified to allow for reverse + operations and formatting of errors. + +=== Features removed + +* SPDY support has been removed. Use HTTP/2 instead. + +* Hooks have been removed. Use xref:streams[stream handlers] instead. + +* The undocumented `waiting_stream` hack has been removed. + It allowed disabling chunked transfer-encoding for HTTP/1.1. + It has no equivalent in Cowboy 2.0. Open a ticket if necessary. + +* Sub protocols still exist, but their interface has largely changed + and they are no longer documented for the time being. + +=== Changed behaviors + +* The handler behaviors have been renamed and are now `cowboy_handler`, + `cowboy_loop`, `cowboy_rest` and `cowboy_websocket`. + +* Plain HTTP, loop, REST and Websocket handlers have had their + init and terminate callbacks unified. They now all use the + `init/2` and `terminate/3` callbacks. The latter is now optional. + The terminate reason has now been documented for all handlers. + +* The tuple returned to switch to a different handler type has + changed. It now takes the form `{Module, Req, State}` or + `{Module, Req, State, Opts}`, where `Opts` is a map of options + to configure the handler. The timeout and hibernate options + must now be specified using this map, where applicable. + +* All behaviors that used to accept `halt` or `shutdown` tuples + as a return value no longer do so. The return value is now + a `stop` tuple, consistent across Cowboy. + +* Middlewares can no longer return an `error` tuple. They have + to send the response and return a `stop` tuple instead. + +* The `known_content_type` REST handler callback has been removed + as it was found unnecessary. + +* Websocket handlers have both the normal `init/2` and + an optional `websocket_init/1` function. The reason for + that exception is that the `websocket_*` callbacks execute + in a separate process from the `init/2` callback, and it + was therefore not obvious how timers or monitors should + be setup properly. They are effectively initializing the + handler before and after the HTTP/1.1 upgrade. + +* Websocket handlers can now send frames directly from + `websocket_init/1`. The frames will be sent immediately + after the handshake. + +* Websocket handler callbacks no longer receive the Req + argument. The `init/2` callback still receives it and + can be used to extract relevant information. The `terminate/3` + callback, if implemented, may still receive the Req + (see next bullet point). + +* Websocket handlers have a new `req_filter` option that + can be used to customize how much information should be + discarded from the Req object after the handshake. Note + that the Req object is only available in `terminate/3` + past that point. + +* Websocket handlers have their timeout default changed + from infinity to 60 seconds. + +=== New functions + +* The `cowboy_req:scheme/1` function has been added. + +* The `cowboy_req:uri/1,2` function has been added, replacing the + less powerful functions `cowboy_req:url/1` and `cowboy_req:host_url/1`. + +* The functions `cowboy_req:match_qs/2` and `cowboy_req:match_cookies/2` + allow matching query string and cookies against constraints. + +* The function `cowboy_req:set_resp_cookie/3` has been added to + complement `cowboy_req:set_resp_cookie/4`. + +* The functions `cowboy_req:resp_header/2,3` and `cowboy_req:resp_headers/1` + have been added. They can be used to retrieve response headers + that were previously set. + +* The function `cowboy_req:set_resp_headers/2` has been added. It + allows setting many response headers at once. + +* The functions `cowboy_req:push/3,4` can be used to push resources + for protocols that support it (by default only HTTP/2). + +=== Changed functions + +* The `cowboy:start_http/4` function was renamed to `cowboy:start_clear/3`. + +* The `cowboy:start_https/4` function was renamed to `cowboy:start_tls/3`. + +* Most, if not all, functions in the `cowboy_req` module have been modified. + Please consult the changelog of each individual functions. The changes + are mainly about simplifying and clarifying the interface. The Req is no + longer returned when not necessary, maps are used wherever possible, + and some functions have been renamed. + +* The position of the `Opts` argument for `cowboy_req:set_resp_cookie/4` + has changed to improve consistency. It is now the last argument. + +=== Removed functions + +* The functions `cowboy_req:url/1` and `cowboy_req:host_url/1` have been + removed in favor of the new function `cowboy_req:uri/1,2`. + +* The functions `cowboy_req:meta/2,3` and `cowboy_req:set_meta/3` have + been removed. The Req object is now a public map, therefore they became + unnecessary. + +* The functions `cowboy_req:set_resp_body_fun/2,3` have been removed. + For sending files, the function `cowboy_req:set_resp_body/2` can now + take a sendfile tuple. + +* Remove many undocumented functions from `cowboy_req`, including the + functions `cowboy_req:get/2` and `cowboy_req:set/3`. + +=== Other changes + +* The correct percent-decoding algorithm is now used for path elements + during routing. It will no longer decode `+` characters. + +* The router will now properly handle path segments `.` and `..`. + +* Routing behavior has changed for URIs containing latin1 characters. + They are no longer allowed. URIs are expected to be in UTF-8 once + they are percent-decoded. + +* Clients that send multiple headers of the same name + will have the values of those headers concatenated into a + comma-separated list. This is of special importance in the + case of the content-type header, as previously only the + first value was used in the `content_types_accepted/2` step + in REST handlers. + +* Etag comparison in REST handlers has been fixed. Some requests may + now fail when they succeeded in the past. + +* The `If-*-Since` headers are now ignored in REST handlers if + the corresponding `If*-Match` header exist. The former is + largely a backward compatible header and this shouldn't create + any issue. The new behavior follows the current RFCs more closely. + +* The static file handler has been improved to handle more special + characters on systems that accept them. diff --git a/docs/en/cowboy/2.7/guide/migrating_from_1.0/index.html b/docs/en/cowboy/2.7/guide/migrating_from_1.0/index.html new file mode 100644 index 00000000..e6d6f00a --- /dev/null +++ b/docs/en/cowboy/2.7/guide/migrating_from_1.0/index.html @@ -0,0 +1,294 @@ +<!DOCTYPE html> +<html lang="en"> + +<head> + <meta charset="utf-8"> + <meta name="viewport" content="width=device-width, initial-scale=1.0"> + <meta name="description" content=""> + <meta name="author" content="Loïc Hoguin based on a design from (Soft10) Pol Cámara"> + + <title>Nine Nines: Migrating from Cowboy 1.0 to 2.0</title> + + <link href='https://fonts.googleapis.com/css?family=Open+Sans:400,700,400italic' rel='stylesheet' type='text/css'> + <link href="/css/99s.css?r=6" rel="stylesheet"> + + <link rel="shortcut icon" href="/img/ico/favicon.ico"> + <link rel="apple-touch-icon-precomposed" sizes="114x114" href="/img/ico/apple-touch-icon-114.png"> + <link rel="apple-touch-icon-precomposed" sizes="72x72" href="/img/ico/apple-touch-icon-72.png"> + <link rel="apple-touch-icon-precomposed" href="/img/ico/apple-touch-icon-57.png"> + + +</head> + + +<body class=""> + <header id="page-head"> + <div id="topbar" class="container"> + <div class="row"> + <div class="span2"> + <h1 id="logo"><a href="/" title="99s">99s</a></h1> + </div> + <div class="span10"> + + <div id="side-header"> + <nav> + <ul> + <li><a title="Hear my thoughts" href="/articles">Articles</a></li> + <li><a title="Watch my talks" href="/talks">Talks</a></li> + <li class="active"><a title="Read the docs" href="/docs">Documentation</a></li> + <li><a title="Request my services" href="/services">Consulting & Training</a></li> + </ul> + </nav> + <ul id="social"> + <li> + <a href="https://github.com/ninenines" title="Check my Github repositories"><img src="/img/ico_github.png" data-hover="/img/ico_github_alt.png" alt="Github"></a> + </li> + <li> + <a title="Contact me" href="mailto:[email protected]"><img src="/img/ico_mail.png" data-hover="/img/ico_mail_alt.png"></a> + </li> + </ul> + </div> + </div> + </div> + </div> + + +</header> + +<div id="contents" class="two_col"> +<div class="container"> +<div class="row"> +<div id="docs" class="span9 maincol"> + +<h1 class="lined-header"><span>Migrating from Cowboy 1.0 to 2.0</span></h1> + +<p>A lot has changed between Cowboy 1.0 and 2.0.

This is no longer the case. +</li> +<li>We no longer send a GOAWAY frame when the HTTP/2 preface is invalid. +</li> +<li>Some values in the Req object of pushed requests were in the wrong type.

The limit is now strict. +</li> +<li>When an early error occurred on the HTTP/1.1 request line, the partial Req given to stream handlers was missing the <code>ref</code> and <code>peer</code> information. This has been corrected. +</li> +<li>Absolute URIs with a userinfo component, or without an authority component, are now properly rejected for HTTP/1.0 and HTTP/1.1. +</li> +<li>Whitespace is no longer allowed in header lines before the colon. +</li> +<li>408 responses to HTTP/1.1 requests now properly include a connection: close header indicating that we are going to close the connection. This header will also be sent for other early errors resulting in the closing of the connection. +</li> +<li>When both the transfer-encoding and content-length headers are sent in an HTTP/1.1 request, the transfer-encoding now takes precedence over the content-length header and the latter is removed from the Req object. +</li> +<li>A 400 response is now returned when the transfer-encoding header is invalid or contains any transfer-coding other than chunked. +</li> +<li>Invalid chunk sizes are now rejected immediately. +</li> +<li>Chunk extensions are now limited to 129 characters.

Cowboy now applies heuristics + to determine whether it is necessary to update the window, + based on the current window size and the amount of data + requested by streams (the `cowboy_req:read_body/2` length + for example).

The option `initial_stream_flow_size` + controls how much data Cowboy will read without + being asked. + +* The HTTP/1.1 and HTTP/2 option `logger` is now + documented. + +* The Websocket option `validate_utf8` has been + added.

The function returns +a `data` or a `file` tuple depending on whether this +is a normal field or a file being uploaded. + +The following snippet will use this function and +use different strategies depending on whether the +part is a file: + +[source,erlang] +---- +multipart(Req0) -> + case cowboy_req:read_part(Req0) of + {ok, Headers, Req1} -> + Req = case cow_multipart:form_data(Headers) of + {data, _FieldName} -> + {ok, _Body, Req2} = cowboy_req:read_part_body(Req1), + Req2; + {file, _FieldName, _Filename, _CType} -> + stream_file(Req1) + end, + multipart(Req); + {done, Req} -> + Req + end. + +stream_file(Req0) -> + case cowboy_req:read_part_body(Req0) of + {ok, _LastBodyChunk, Req} -> + Req; + {more, _BodyChunk, Req} -> + stream_file(Req) + end. +---- + +Both the part header and body reading functions can take +options that will be given to the request body reading +functions.

They are the fields that have +a direct mapping to HTTP: the request `method`; the HTTP +`version` used; the effective URI components `scheme`, +`host`, `port`, `path` and `qs`; the request `headers`; +the connection `peer` address and port; and the TLS +certificate `cert` when applicable. + +Note that the `version` field can be used to determine +whether a connection is using HTTP/2. + +To access a field, you can simply match in the function +head. The following example sends a simple "Hello world!" +response when the `method` is GET, and a 405 error +otherwise. + +[source,erlang] +---- +init(Req0=#{method := <<"GET">>}, State) -> + Req = cowboy_req:reply(200, #{ + <<"content-type">> => <<"text/plain">> + }, <<"Hello world!">>, Req0), + {ok, Req, State}; +init(Req0, State) -> + Req = cowboy_req:reply(405, #{ + <<"allow">> => <<"GET">> + }, Req0), + {ok, Req, State}. +---- + +Any other field is internal and should not be accessed. +They may change in future releases, including maintenance +releases, without notice. + +Modifying the Req object, while allowed, is not recommended +unless strictly necessary. If adding new fields, make sure +to namespace the field names so that no conflict can occur +with future Cowboy updates or third party projects. + +=== Introduction to the cowboy_req interface + +// @todo Link to cowboy_req manual + +Functions in the `cowboy_req` module provide access to +the request information but also various operations that +are common when dealing with HTTP requests. + +All the functions that begin with a verb indicate an action. +Other functions simply return the corresponding value +(sometimes that value does need to be built, but the +cost of the operation is equivalent to retrieving a value). + +Some of the `cowboy_req` functions return an updated Req +object. They are the read, reply, set and delete functions. +While ignoring the returned Req will not cause incorrect +behavior for some of them, it is highly recommended to +always keep and use the last returned Req object. The +manual for `cowboy_req` details these functions and what +modifications are done to the Req object. + +Some of the calls to `cowboy_req` have side effects. This +is the case of the read and reply functions. Cowboy reads +the request body or replies immediately when the function +is called. + +All functions will crash if something goes wrong. There +is usually no need to catch these errors, Cowboy will +send the appropriate 4xx or 5xx response depending on +where the crash occurred. + +=== Request method + +The request method can be retrieved directly: + +[source, erlang] +#{method := Method} = Req. + +Or using a function: + +[source,erlang] +Method = cowboy_req:method(Req). + +The method is a case sensitive binary string. Standard +methods include GET, HEAD, OPTIONS, PATCH, POST, PUT +or DELETE. + +=== HTTP version + +The HTTP version is informational. It does not indicate that +the client implements the protocol well or fully. + +There is typically no need to change behavior based on the +HTTP version: Cowboy already does it for you. + +It can be useful in some cases, though. For example, one may +want to redirect HTTP/1.1 clients to use Websocket, while HTTP/2 +clients keep using HTTP/2. + +The HTTP version can be retrieved directly: + +[source,erlang] +#{version := Version} = Req. + +Or using a function: + +[source,erlang] +Version = cowboy_req:version(Req). + +Cowboy defines the `'HTTP/1.0'`, `'HTTP/1.1'` and `'HTTP/2'` +versions. Custom protocols can define their own values as +atoms. + +=== Effective request URI + +The scheme, host, port, path and query string components +of the effective request URI can all be retrieved directly: + +[source,erlang] +---- +#{ + scheme := Scheme, + host := Host, + port := Port, + path := Path, + qs := Qs +} = Req. +---- + +Or using the related functions: + +[source,erlang] +Scheme = cowboy_req:scheme(Req), +Host = cowboy_req:host(Req), +Port = cowboy_req:port(Req), +Path = cowboy_req:path(Req). +Qs = cowboy_req:qs(Req). + +The scheme and host are lowercased case insensitive binary +strings. The port is an integer representing the port number. +The path and query string are case sensitive binary strings. + +Cowboy defines only the `<<"http">>` and `<<"https">>` schemes. +They are chosen so that the scheme will only be `<<"https">>` +for requests on secure HTTP/1.1 or HTTP/2 connections. +// @todo Is that tested well? + +The effective request URI itself can be reconstructed with +the `cowboy_req:uri/1,2` function. By default, an absolute +URI is returned: + +[source,erlang] +%% scheme://host[:port]/path[?qs] +URI = cowboy_req:uri(Req). + +Options are available to either disable or replace some +or all of the components. Various URIs or URI formats can +be generated this way, including the origin form: + +[source,erlang] +%% /path[?qs] +URI = cowboy_req:uri(Req, #{host => undefined}). + +The protocol relative form: + +[source,erlang] +%% //host[:port]/path[?qs] +URI = cowboy_req:uri(Req, #{scheme => undefined}). + +The absolute URI without a query string: + +[source,erlang] +URI = cowboy_req:uri(Req, #{qs => undefined}). + +A different host: + +[source,erlang] +URI = cowboy_req:uri(Req, #{host => <<"example.org">>}). + +And any other combination. + +=== Bindings + +Bindings are the host and path components that you chose +to extract when defining the routes of your application. +They are only available after the routing. + +Cowboy provides functions to retrieve one or all bindings. + +To retrieve a single value: + +[source,erlang] +Value = cowboy_req:binding(userid, Req). + +When attempting to retrieve a value that was not bound, +`undefined` will be returned. A different default value +can be provided: + +[source,erlang] +Value = cowboy_req:binding(userid, Req, 42). + +To retrieve everything that was bound: + +[source,erlang] +Bindings = cowboy_req:bindings(Req). + +They are returned as a map, with keys being atoms. + +The Cowboy router also allows you to capture many host +or path segments at once using the `...` qualifier. + +To retrieve the segments captured from the host name: + +[source,erlang] +HostInfo = cowboy_req:host_info(Req). + +And the path segments: + +[source,erlang] +PathInfo = cowboy_req:path_info(Req). + +Cowboy will return `undefined` if `...` was not used +in the route. + +=== Query parameters + +Cowboy provides two functions to access query parameters. +You can use the first to get the entire list of parameters. + +[source,erlang] +QsVals = cowboy_req:parse_qs(Req), +{_, Lang} = lists:keyfind(<<"lang">>, 1, QsVals). + +Cowboy will only parse the query string, and not do any +transformation. This function may therefore return duplicates, +or parameter names without an associated value. The order of +the list returned is undefined. + +When a query string is `key=1&key=2`, the list returned will +contain two parameters of name `key`. + +The same is true when trying to use the PHP-style suffix `[]`. +When a query string is `key[]=1&key[]=2`, the list returned will +contain two parameters of name `key[]`. + +When a query string is simply `key`, Cowboy will return the +list `[{<<"key">>, true}]`, using `true` to indicate that the +parameter `key` was defined, but with no value. + +The second function Cowboy provides allows you to match out +only the parameters you are interested in, and at the same +time do any post processing you require using xref:constraints[constraints]. +This function returns a map. + +[source,erlang] +#{id := ID, lang := Lang} = cowboy_req:match_qs([id, lang], Req). + +Constraints can be applied automatically. The following +snippet will crash when the `id` parameter is not an integer, +or when the `lang` parameter is empty. At the same time, the +value for `id` will be converted to an integer term: + +[source,erlang] +QsMap = cowboy_req:match_qs([{id, int}, {lang, nonempty}], Req). + +A default value may also be provided. The default will be used +if the `lang` key is not found. It will not be used if +the key is found but has an empty value. + +[source,erlang] +#{lang := Lang} = cowboy_req:match_qs([{lang, [], <<"en-US">>}], Req). + +If no default is provided and the value is missing, the +query string is deemed invalid and the process will crash. + +When the query string is `key=1&key=2`, the value for `key` +will be the list `[1, 2]`. Parameter names do not need to +include the PHP-style suffix. Constraints may be used to +ensure that only one value was passed through. + +=== Headers + +Header values can be retrieved either as a binary string +or parsed into a more meaningful representation. + +The get the raw value: + +[source,erlang] +HeaderVal = cowboy_req:header(<<"content-type">>, Req). + +Cowboy expects all header names to be provided as lowercase +binary strings. This is true for both requests and responses, +regardless of the underlying protocol. + +When the header is missing from the request, `undefined` +will be returned. A different default can be provided: + +[source,erlang] +HeaderVal = cowboy_req:header(<<"content-type">>, Req, <<"text/plain">>). + +All headers can be retrieved at once, either directly: + +[source,erlang] +#{headers := AllHeaders} = Req. + +Or using a function: + +[source,erlang] +AllHeaders = cowboy_req:headers(Req). + +Cowboy provides equivalent functions to parse individual +headers. There is no function to parse all headers at once. + +To parse a specific header: + +[source,erlang] +ParsedVal = cowboy_req:parse_header(<<"content-type">>, Req). + +An exception will be thrown if it doesn't know how to parse the +given header, or if the value is invalid.

They are the fields that have a direct mapping to HTTP: the request <code>method</code>; the HTTP <code>version</code> used; the effective URI components <code>scheme</code>, <code>host</code>, <code>port</code>, <code>path</code> and <code>qs</code>; the request <code>headers</code>; the connection <code>peer</code> address and port; and the TLS certificate <code>cert</code> when applicable.</p> +<p>Note that the <code>version</code> field can be used to determine whether a connection is using HTTP/2.</p> +<p>To access a field, you can simply match in the function head.

Other functions simply return the corresponding value (sometimes that value does need to be built, but the cost of the operation is equivalent to retrieving a value).</p> +<p>Some of the <code>cowboy_req</code> functions return an updated Req object. They are the read, reply, set and delete functions. While ignoring the returned Req will not cause incorrect behavior for some of them, it is highly recommended to always keep and use the last returned Req object. The manual for <code>cowboy_req</code> details these functions and what modifications are done to the Req object.</p> +<p>Some of the calls to <code>cowboy_req</code> have side effects. This is the case of the read and reply functions. Cowboy reads the request body or replies immediately when the function is called.</p> +<p>All functions will crash if something goes wrong.

An iolist is a list containing +binaries, characters, strings or other iolists. This +allows you to build a response from different parts +without having to do any concatenation: + +[source,erlang] +---- +Title = "Hello world!", +Body = <<"Hats off!">>, +Req = cowboy_req:reply(200, #{ + <<"content-type">> => <<"text/html">> +}, ["<html><head><title>", Title, "</title></head>", + "<body><p>", Body, "</p></body></html>"], Req0). +---- + +This method of building responses is more efficient than +concatenating. Behind the scenes, each element of the list +is simply a pointer, and those pointers are used directly +when writing to the socket. + +=== Stream reply + +Cowboy provides two functions for initiating a response, +and an additional function for streaming the response body. +Cowboy will add any required headers to the response. + +// @todo For HTTP/1.1 Cowboy should probably not use chunked transfer-encoding if the content-length is set. + +When you need to set only the status code, +use `cowboy_req:stream_reply/2`: + +[source,erlang] +---- +Req = cowboy_req:stream_reply(200, Req0), + +cowboy_req:stream_body("Hello...", nofin, Req), +cowboy_req:stream_body("chunked...", nofin, Req), +cowboy_req:stream_body("world!!", fin, Req). +---- + +The second argument to `cowboy_req:stream_body/3` indicates +whether this data terminates the body. Use `fin` for the +final flag, and `nofin` otherwise. + +This snippet does not set a content-type header. This is +not recommended. All responses with a body should have +a content-type. The header can be set beforehand, or +using the `cowboy_req:stream_reply/3`: + +[source,erlang] +---- +Req = cowboy_req:stream_reply(200, #{ + <<"content-type">> => <<"text/html">> +}, Req0), + +cowboy_req:stream_body("<html><head>Hello world!</head>", nofin, Req), +cowboy_req:stream_body("<body><p>Hats off!</p></body></html>", fin, Req). +---- + +HTTP provides a few different ways to stream response bodies. +Cowboy will select the most appropriate one based on the HTTP +version and the request and response headers. + +While not required by any means, it is recommended that you +set the content-length header in the response if you know it +in advance. This will ensure that the best response method +is selected and help clients understand when the response +is fully received. + +Cowboy also provides a function to send response trailers. +Response trailers are semantically equivalent to the headers +you send in the response, only they are sent at the end. +This is especially useful to attach information to the +response that could not be generated until the response +body was fully generated. + +Trailer fields must be listed in the trailer header. Any +field not listed might be dropped by the client or an intermediary. + +[source,erlang] +---- +Req = cowboy_req:stream_reply(200, #{ + <<"content-type">> => <<"text/html">>, + <<"trailer">> => <<"expires, content-md5">> +}, Req0), + +cowboy_req:stream_body("<html><head>Hello world!</head>", nofin, Req), +cowboy_req:stream_body("<body><p>Hats off!</p></body></html>", nofin, Req), + +cowboy_req:stream_trailers(#{ + <<"expires">> => <<"Sun, 10 Dec 2017 19:13:47 GMT">>, + <<"content-md5">> => <<"c6081d20ff41a42ce17048ed1c0345e2">> +}, Req). +---- + +The stream ends with trailers. It is no longer possible to +send data after sending trailers. You cannot send trailers +after setting the `fin` flag when streaming the body. + +=== Preset response headers + +Cowboy provides functions to set response headers without +immediately sending them. They are stored in the Req object +and sent as part of the response when a reply function is +called. + +To set response headers: + +[source,erlang] +Req = cowboy_req:set_resp_header(<<"allow">>, "GET", Req0). + +Header names must be a lowercase binary. + +Do not use this function for setting cookies. Refer to +the xref:cookies[Cookies] chapter for more information. + +To check if a response header has already been set: + +[source,erlang] +cowboy_req:has_resp_header(<<"allow">>, Req). + +It returns `true` if the header was set, `false` otherwise. + +To delete a response header that was set previously: + +[source,erlang] +Req = cowboy_req:delete_resp_header(<<"allow">>, Req0). + +=== Overriding headers + +As Cowboy provides different ways of setting response +headers and body, clashes may occur, so it's important +to understand what happens when a header is set twice. + +Headers come from five different origins: + +* Protocol-specific headers (for example HTTP/1.1's connection header) +* Other required headers (for example the date header) +* Preset headers +* Headers given to the reply function +* Set-cookie headers + +Cowboy does not allow overriding protocol-specific headers. + +Set-cookie headers will always be appended at the end of +the list of headers before sending the response. + +Headers given to the reply function will always override +preset headers and required headers. If a header is found +in two or three of these, then the one in the reply function +is picked and the others are dropped. + +Similarly, preset headers will always override required +headers. + +To illustrate, look at the following snippet. Cowboy by +default sends the server header with the value "Cowboy". +We can override it: + +[source,erlang] +---- +Req = cowboy_req:reply(200, #{ + <<"server">> => <<"yaws">> +}, Req0). +---- + +=== Preset response body + +Cowboy provides functions to set the response body without +immediately sending it. It is stored in the Req object and +sent when the reply function is called. + +To set the response body: + +[source,erlang] +Req = cowboy_req:set_resp_body("Hello world!", Req0). + +// @todo Yeah we probably should add that function that +// also sets the content-type at the same time... + +To check if a response body has already been set: + +[source,erlang] +cowboy_req:has_resp_body(Req). + +It returns `true` if the body was set and is non-empty, +`false` otherwise. + +// @todo We probably should also have a function that +// properly removes the response body, including any +// content-* headers. + +The preset response body is only sent if the reply function +used is `cowboy_req:reply/2` or `cowboy_req:reply/3`. + +=== Sending files + +Cowboy provides a shortcut for sending files. When +using `cowboy_req:reply/4`, or when presetting the +response header, you can give a `sendfile` tuple to +Cowboy: + +[source,erlang] +{sendfile, Offset, Length, Filename} + +Depending on the values for `Offset` or `Length`, the +entire file may be sent, or just a part of it. + +The length is required even for sending the entire file. +Cowboy sends it in the content-length header. + +To send a file while replying: + +[source,erlang] +---- +Req = cowboy_req:reply(200, #{ + <<"content-type">> => "image/png" +}, {sendfile, 0, 12345, "path/to/logo.png"}, Req0). +---- + +// @todo An example of presetting a file would be useful, +// but let's wait for the function that can set the +// content-type at the same time. + +// @todo What about streaming many files? For example +// it should be possible to build a tar file on the fly +// while still using sendfile. Another example could be +// proper support for multipart byte ranges. Yet another +// example would be automatic concatenation of CSS or JS +// files. + +=== Informational responses + +Cowboy allows you to send informational responses. + +Informational responses are responses that have a status +code between 100 and 199. Any number can be sent before +the proper response. Sending an informational response +does not change the behavior of the proper response, and +clients are expected to ignore any informational response +they do not understand. + +The following snippet sends a 103 informational response +with some headers that are expected to be in the final +response. + +[source,erlang] +---- +Req = cowboy_req:inform(103, #{ + <<"link">> => <<"</style.css>; rel=preload; as=style, </script.js>; rel=preload; as=script">> +}, Req0). +---- + +=== Push + +The HTTP/2 protocol introduced the ability to push resources +related to the one sent in the response. Cowboy provides two +functions for that purpose: `cowboy_req:push/3,4`. + +Push is only available for HTTP/2. Cowboy will automatically +ignore push requests if the protocol doesn't support it. + +The push function must be called before any of the reply +functions. Doing otherwise will result in a crash. + +To push a resource, you need to provide the same information +as a client performing a request would. This includes the +HTTP method, the URI and any necessary request headers. + +Cowboy by default only requires you to give the path to +the resource and the request headers. The rest of the URI +is taken from the current request (excluding the query +string, set to empty) and the method is GET by default. + +The following snippet pushes a CSS file that is linked to +in the response: + +[source,erlang] +---- +cowboy_req:push("/static/style.css", #{ + <<"accept">> => <<"text/css">> +}, Req0), +Req = cowboy_req:reply(200, #{ + <<"content-type">> => <<"text/html">> +}, ["<html><head><title>My web page</title>", + "<link rel='stylesheet' type='text/css' href='/static/style.css'>", + "<body><p>Welcome to Erlang!</p></body></html>"], Req0). +---- + +To override the method, scheme, host, port or query string, +simply pass in a fourth argument. The following snippet +uses a different host name: + +[source,erlang] +---- +cowboy_req:push("/static/style.css", #{ + <<"accept">> => <<"text/css">> +}, #{host => <<"cdn.example.org">>}, Req), +---- + +Pushed resources don't have to be files. As long as the push +request is cacheable, safe and does not include a body, the +resource can be pushed. + +Under the hood, Cowboy handles pushed requests the same as +normal requests: a different process is created which will +ultimately send a response to the client. diff --git a/docs/en/cowboy/2.7/guide/resp/index.html b/docs/en/cowboy/2.7/guide/resp/index.html new file mode 100644 index 00000000..da4dcea4 --- /dev/null +++ b/docs/en/cowboy/2.7/guide/resp/index.html @@ -0,0 +1,423 @@ +<!DOCTYPE html> +<html lang="en"> + +<head> + <meta charset="utf-8"> + <meta name="viewport" content="width=device-width, initial-scale=1.0"> + <meta name="description" content=""> + <meta name="author" content="Loïc Hoguin based on a design from (Soft10) Pol Cámara"> + + <title>Nine Nines: Sending a response</title> + + <link href='https://fonts.googleapis.com/css?family=Open+Sans:400,700,400italic' rel='stylesheet' type='text/css'> + <link href="/css/99s.css?r=6" rel="stylesheet"> + + <link rel="shortcut icon" href="/img/ico/favicon.ico"> + <link rel="apple-touch-icon-precomposed" sizes="114x114" href="/img/ico/apple-touch-icon-114.png"> + <link rel="apple-touch-icon-precomposed" sizes="72x72" href="/img/ico/apple-touch-icon-72.png"> + <link rel="apple-touch-icon-precomposed" href="/img/ico/apple-touch-icon-57.png"> + + +</head> + + +<body class=""> + <header id="page-head"> + <div id="topbar" class="container"> + <div class="row"> + <div class="span2"> + <h1 id="logo"><a href="/" title="99s">99s</a></h1> + </div> + <div class="span10"> + + <div id="side-header"> + <nav> + <ul> + <li><a title="Hear my thoughts" href="/articles">Articles</a></li> + <li><a title="Watch my talks" href="/talks">Talks</a></li> + <li class="active"><a title="Read the docs" href="/docs">Documentation</a></li> + <li><a title="Request my services" href="/services">Consulting & Training</a></li> + </ul> + </nav> + <ul id="social"> + <li> + <a href="https://github.com/ninenines" title="Check my Github repositories"><img src="/img/ico_github.png" data-hover="/img/ico_github_alt.png" alt="Github"></a> + </li> + <li> + <a title="Contact me" href="mailto:[email protected]"><img src="/img/ico_mail.png" data-hover="/img/ico_mail_alt.png"></a> + </li> + </ul> + </div> + </div> + </div> + </div> + + +</header> + +<div id="contents" class="two_col"> +<div class="container"> +<div class="row"> +<div id="docs" class="span9 maincol"> + +<h1 class="lined-header"><span>Sending a response</span></h1> + +<p>The response must be sent using the Req object.</p> +<p>Cowboy provides two different ways of sending responses: either directly or by streaming the body.

different diagrams. + +There are four main paths that requests may follow. One for the +method OPTIONS; one for the methods GET and HEAD; one for the +methods PUT, POST and PATCH; and one for the method DELETE. + +All paths start with the "Start" diagram, and all paths excluding +the OPTIONS path go through the "Content negotiation" diagram +and optionally the "Conditional requests" diagram if the resource +exists. + +The red squares refer to another diagram. The light green squares +indicate a response. Other squares may be either a callback or a +question answered by Cowboy itself. Green arrows tend to indicate +the default behavior if the callback is undefined.

It is only processed +at the end of the "PUT, POST and PATCH methods" diagram, +when all conditions have been met. + +The `known_methods` and `allowed_methods` callbacks +return a list of methods. Cowboy then checks if the request +method is in the list, and stops otherwise. + +The `is_authorized` callback may be used to check that +access to the resource is authorized. Authentication +may also be performed as needed. When authorization is +denied, the return value from the callback must include +a challenge applicable to the requested resource, which +will be sent back to the client in the www-authenticate +header. + +This diagram is immediately followed by either the +"OPTIONS method" diagram when the request method is +OPTIONS, or the "Content negotiation" diagram otherwise. + +=== OPTIONS method + +This diagram only applies to OPTIONS requests. + +image::rest_options.png[REST OPTIONS method flowchart] + +The `options` callback may be used to add information +about the resource, such as media types or languages +provided; allowed methods; any extra information.

It then automatically select the best match +based on the request. + +If a callback is not defined, Cowboy will select the +content-type, language or charset that the client +prefers. + +The `content_types_provided` also returns the name of +a callback for every content-type it accepts. This +callback will only be called at the end of the +"GET and HEAD methods" diagram, when all conditions +have been met. + +The selected content-type, language and charset are +saved as meta values in the Req object.

This is the callback +you defined for each content-types you returned from +`content_types_provided`. This callback returns the body +that will be sent back to the client, or a fun if the +body must be streamed. + +When the resource does not exist, Cowboy will figure out +whether the resource existed previously, and if so whether +it was moved elsewhere in order to redirect the client to +the new URI. + +The `moved_permanently` and `moved_temporarily` callbacks +must return the new location of the resource if it was in +fact moved. + +=== PUT, POST and PATCH methods + +This diagram only applies to PUT, POST and PATCH requests. + +For a description of the `cond` step, please see +the "Conditional requests" diagram. + +image::rest_put_post_patch.png[REST PUT/POST/PATCH methods flowchart] + +When the resource exists, first the conditional steps +are executed. When that succeeds, and the method is PUT, +Cowboy will call the `is_conflict` callback. This function +can be used to prevent potential race conditions, by locking +the resource for example. + +Then all three methods reach the `content_types_accepted` +step that we will describe in a few paragraphs. + +When the resource does not exist, and the method is PUT, +Cowboy will check for conflicts and then move on to the +`content_types_accepted` step. For other methods, Cowboy +will figure out whether the resource existed previously, +and if so whether it was moved elsewhere. If the resource +is truly non-existent, the method is POST and the call +for `allow_missing_post` returns `true`, then Cowboy will +move on to the `content_types_accepted` step. Otherwise +the request processing ends there. + +The `moved_permanently` and `moved_temporarily` callbacks +must return the new location of the resource if it was in +fact moved. + +The `content_types_accepted` returns a list of +content-types it accepts, but also the name of a callback +for each of them. Cowboy will select the appropriate +callback for processing the request body and call it. + +This callback may return one of three different return +values. + +If an error occurred while processing the request body, +it must return `false` and Cowboy will send an +appropriate error response. + +If the method is POST, then you may return `true` with +an URI of where the resource has been created. This is +especially useful for writing handlers for collections. + +Otherwise, return `true` to indicate success. Cowboy +will select the appropriate response to be sent depending +on whether a resource has been created, rather than +modified, and on the availability of a location header +or a body in the response. + +=== DELETE method + +This diagram only applies to DELETE requests. + +For a description of the `cond` step, please see +the "Conditional requests" diagram. + +image::rest_delete.png[REST DELETE method flowchart] + +When the resource exists, and the conditional steps +succeed, the resource can be deleted. + +Deleting the resource is a two steps process. First +the callback `delete_resource` is executed. Use this +callback to delete the resource. + +Because the resource may be cached, you must also +delete all cached representations of this resource +in the system. This operation may take a while though, +so you may return before it finished. + +Cowboy will then call the `delete_completed` callback. +If you know that the resource has been completely +deleted from your system, including from caches, then +you can return `true`. If any doubts persist, return +`false`. Cowboy will assume `true` by default. + +To finish, Cowboy checks if you set a response body, +and depending on that, sends the appropriate response. + +When the resource does not exist, Cowboy will figure out +whether the resource existed previously, and if so whether +it was moved elsewhere in order to redirect the client to +the new URI. + +The `moved_permanently` and `moved_temporarily` callbacks +must return the new location of the resource if it was in +fact moved. + +=== Conditional requests + +This diagram applies to all request methods other than +OPTIONS. It is executed right after the `resource_exists` +callback, when the resource exists. + +image::rest_cond.png[REST conditional requests flowchart] + +A request becomes conditional when it includes either of +the if-match header; the if-unmodified-since header; the +if-none-match header; or the if-modified-since header. + +If the condition fails, the request ends immediately +without any retrieval or modification of the resource. + +The `generate_etag` and `last_modified` are called as +needed. Cowboy will only call them once and then cache +the results for subsequent use. diff --git a/docs/en/cowboy/2.7/guide/rest_flowcharts/index.html b/docs/en/cowboy/2.7/guide/rest_flowcharts/index.html new file mode 100644 index 00000000..2f81d19a --- /dev/null +++ b/docs/en/cowboy/2.7/guide/rest_flowcharts/index.html @@ -0,0 +1,238 @@ +<!DOCTYPE html> +<html lang="en"> + +<head> + <meta charset="utf-8"> + <meta name="viewport" content="width=device-width, initial-scale=1.0"> + <meta name="description" content=""> + <meta name="author" content="Loïc Hoguin based on a design from (Soft10) Pol Cámara"> + + <title>Nine Nines: REST flowcharts</title> + + <link href='https://fonts.googleapis.com/css?family=Open+Sans:400,700,400italic' rel='stylesheet' type='text/css'> + <link href="/css/99s.css?r=6" rel="stylesheet"> + + <link rel="shortcut icon" href="/img/ico/favicon.ico"> + <link rel="apple-touch-icon-precomposed" sizes="114x114" href="/img/ico/apple-touch-icon-114.png"> + <link rel="apple-touch-icon-precomposed" sizes="72x72" href="/img/ico/apple-touch-icon-72.png"> + <link rel="apple-touch-icon-precomposed" href="/img/ico/apple-touch-icon-57.png"> + + +</head> + + +<body class=""> + <header id="page-head"> + <div id="topbar" class="container"> + <div class="row"> + <div class="span2"> + <h1 id="logo"><a href="/" title="99s">99s</a></h1> + </div> + <div class="span10"> + + <div id="side-header"> + <nav> + <ul> + <li><a title="Hear my thoughts" href="/articles">Articles</a></li> + <li><a title="Watch my talks" href="/talks">Talks</a></li> + <li class="active"><a title="Read the docs" href="/docs">Documentation</a></li> + <li><a title="Request my services" href="/services">Consulting & Training</a></li> + </ul> + </nav> + <ul id="social"> + <li> + <a href="https://github.com/ninenines" title="Check my Github repositories"><img src="/img/ico_github.png" data-hover="/img/ico_github_alt.png" alt="Github"></a> + </li> + <li> + <a title="Contact me" href="mailto:[email protected]"><img src="/img/ico_mail.png" data-hover="/img/ico_mail_alt.png"></a> + </li> + </ul> + </div> + </div> + </div> + </div> + + +</header> + +<div id="contents" class="two_col"> +<div class="container"> +<div class="row"> +<div id="docs" class="span9 maincol"> + +<h1 class="lined-header"><span>REST flowcharts</span></h1> + +<p>This chapter will explain the REST handler state machine through a number of different diagrams.</p> +<p>There are four main paths that requests may follow.

First the callback <code>delete_resource</code> is executed. Use this callback to delete the resource.</p> +<p>Because the resource may be cached, you must also delete all cached representations of this resource in the system. This operation may take a while though, so you may return before it finished.</p> +<p>Cowboy will then call the <code>delete_completed</code> callback. If you know that the resource has been completely deleted from your system, including from caches, then you can return <code>true</code>. If any doubts persist, return <code>false</code>. Cowboy will assume <code>true</code> by default.</p> +<p>To finish, Cowboy checks if you set a response body, and depending on that, sends the appropriate response.</p> +<p>When the resource does not exist, Cowboy will figure out whether the resource existed previously, and if so whether it was moved elsewhere in order to redirect the client to the new URI.</p> +<p>The <code>moved_permanently</code> and <code>moved_temporarily</code> callbacks must return the new location of the resource if it was in fact moved.</p> +<h2 id="_conditional_requests">Conditional requests</h2> +<p>This diagram applies to all request methods other than OPTIONS.

+[[rest_principles]] +== REST principles + +This chapter will attempt to define the concepts behind REST +and explain what makes a service RESTful. + +REST is often confused with performing a distinct operation +depending on the HTTP method, while using more than the GET +and POST methods. That's highly misguided at best. + +We will first attempt to define REST and will look at what +it means in the context of HTTP and the Web. +For a more in-depth explanation of REST, you can read +http://www.ics.uci.edu/~fielding/pubs/dissertation/top.htm[Roy T. Fielding's dissertation] +as it does a great job explaining where it comes from and +what it achieves. + +=== REST architecture + +REST is a *client-server* architecture. The client and the server +both have a different set of concerns. The server stores and/or +manipulates information and makes it available to the user in +an efficient manner. The client takes that information and +displays it to the user and/or uses it to perform subsequent +requests for information. This separation of concerns allows both +the client and the server to evolve independently as it only +requires that the interface stays the same. + +REST is *stateless*. That means the communication between the +client and the server always contains all the information needed +to perform the request. There is no session state in the server, +it is kept entirely on the client's side. If access to a resource +requires authentication, then the client needs to authenticate +itself with every request. + +REST is *cacheable*. The client, the server and any intermediary +components can all cache resources in order to improve performance. + +REST provides a *uniform interface* between components. This +simplifies the architecture, as all components follow the same +rules to speak to one another. It also makes it easier to understand +the interactions between the different components of the system. +A number of constraints are required to achieve this. They are +covered in the rest of the chapter. + +REST is a *layered system*. Individual components cannot see +beyond the immediate layer with which they are interacting. This +means that a client connecting to an intermediate component, like +a proxy, has no knowledge of what lies beyond. This allows +components to be independent and thus easily replaceable or +extendable. + +REST optionally provides *code on demand*. Code may be downloaded +to extend client functionality. This is optional however because +the client may not be able to download or run this code, and so +a REST component cannot rely on it being executed. + +=== Resources and resource identifiers + +A resource is an abstract concept. In a REST system, any information +that can be named may be a resource. This includes documents, images, +a collection of resources and any other information. Any information +that can be the target of an hypertext link can be a resource. + +A resource is a conceptual mapping to a set of entities. The set of +entities evolves over time; a resource doesn't. For example, a resource +can map to "users who have logged in this past month" and another +to "all users". At some point in time they may map to the same set of +entities, because all users logged in this past month. But they are +still different resources. Similarly, if nobody logged in recently, +then the first resource may map to the empty set. This resource exists +regardless of the information it maps to. + +Resources are identified by uniform resource identifiers, also known +as URIs. Sometimes internationalized resource identifiers, or IRIs, +may also be used, but these can be directly translated into a URI. + +In practice we will identify two kinds of resources. Individual +resources map to a set of one element, for example "user Joe". +Collection of resources map to a set of 0 to N elements, +for example "all users". + +=== Resource representations + +The representation of a resource is a sequence of bytes associated +with metadata. + +The metadata comes as a list of key-value pairs, where the name +corresponds to a standard that defines the value's structure and +semantics. With HTTP, the metadata comes in the form of request +or response headers. The headers' structure and semantics are well +defined in the HTTP standard. Metadata includes representation +metadata, resource metadata and control data. + +The representation metadata gives information about the +representation, such as its media type, the date of last +modification, or even a checksum. + +Resource metadata could be link to related resources or +information about additional representations of the resource. + +Control data allows parameterizing the request or response. +For example, we may only want the representation returned if +it is more recent than the one we have in cache. Similarly, +we may want to instruct the client about how it should cache +the representation. This isn't restricted to caching. We may, +for example, want to store a new representation of a resource +only if it wasn't modified since we first retrieved it. + +The data format of a representation is also known as the media +type. Some media types are intended for direct rendering to the +user, while others are intended for automated processing. The +media type is a key component of the REST architecture. + +=== Self-descriptive messages + +Messages must be self-descriptive. That means that the data +format of a representation must always come with its media +type (and similarly requesting a resource involves choosing +the media type of the representation returned). If you are +sending HTML, then you must say it is HTML by sending the +media type with the representation. In HTTP this is done +using the content-type header. + +The media type is often an IANA registered media type, like +`text/html` or `image/png`, but does not need to be. Exactly +two things are important for respecting this constraint: that +the media type is well specified, and that the sender and +recipient agree about what the media type refers to. + +This means that you can create your own media types, like +`application/x-mine`, and that as long as you write the +specifications for it and that both endpoints agree about +it then the constraint is respected. + +=== Hypermedia as the engine of application state + +The last constraint is generally where services that claim +to be RESTful fail. Interactions with a server must be +entirely driven by hypermedia.

That's highly misguided at best.</p> +<p>We will first attempt to define REST and will look at what it means in the context of HTTP and the Web. For a more in-depth explanation of REST, you can read <a href="http://www.ics.uci.edu/~fielding/pubs/dissertation/top.htm">Roy T. Fielding's dissertation</a> as it does a great job explaining where it comes from and what it achieves.</p> +<h2 id="_rest_architecture">REST architecture</h2> +<p>REST is a <strong>client-server</strong> architecture. The client and the server both have a different set of concerns. The server stores and/or manipulates information and makes it available to the user in an efficient manner. The client takes that information and displays it to the user and/or uses it to perform subsequent requests for information. This separation of concerns allows both the client and the server to evolve independently as it only requires that the interface stays the same.</p> +<p>REST is <strong>stateless</strong>. That means the communication between the client and the server always contains all the information needed to perform the request. There is no session state in the server, it is kept entirely on the client's side. If access to a resource requires authentication, then the client needs to authenticate itself with every request.</p> +<p>REST is <strong>cacheable</strong>. The client, the server and any intermediary components can all cache resources in order to improve performance.</p> +<p>REST provides a <strong>uniform interface</strong> between components. This simplifies the architecture, as all components follow the same rules to speak to one another. It also makes it easier to understand the interactions between the different components of the system. A number of constraints are required to achieve this. They are covered in the rest of the chapter.</p> +<p>REST is a <strong>layered system</strong>. Individual components cannot see beyond the immediate layer with which they are interacting. This means that a client connecting to an intermediate component, like a proxy, has no knowledge of what lies beyond. This allows components to be independent and thus easily replaceable or extendable.</p> +<p>REST optionally provides <strong>code on demand</strong>. Code may be downloaded to extend client functionality. This is optional however because the client may not be able to download or run this code, and so a REST component cannot rely on it being executed.</p> +<h2 id="_resources_and_resource_identifiers">Resources and resource identifiers</h2> +<p>A resource is an abstract concept. In a REST system, any information that can be named may be a resource. This includes documents, images, a collection of resources and any other information. Any information that can be the target of an hypertext link can be a resource.</p> +<p>A resource is a conceptual mapping to a set of entities. The set of entities evolves over time; a resource doesn't. For example, a resource can map to "users who have logged in this past month" and another to "all users". At some point in time they may map to the same set of entities, because all users logged in this past month. But they are still different resources. Similarly, if nobody logged in recently, then the first resource may map to the empty set. This resource exists regardless of the information it maps to.</p> +<p>Resources are identified by uniform resource identifiers, also known as URIs. Sometimes internationalized resource identifiers, or IRIs, may also be used, but these can be directly translated into a URI.</p> +<p>In practice we will identify two kinds of resources. Individual resources map to a set of one element, for example "user Joe". Collection of resources map to a set of 0 to N elements, for example "all users".</p> +<h2 id="_resource_representations">Resource representations</h2> +<p>The representation of a resource is a sequence of bytes associated with metadata.</p> +<p>The metadata comes as a list of key-value pairs, where the name corresponds to a standard that defines the value's structure and semantics. With HTTP, the metadata comes in the form of request or response headers. The headers' structure and semantics are well defined in the HTTP standard. Metadata includes representation metadata, resource metadata and control data.</p> +<p>The representation metadata gives information about the representation, such as its media type, the date of last modification, or even a checksum.</p> +<p>Resource metadata could be link to related resources or information about additional representations of the resource.</p> +<p>Control data allows parameterizing the request or response. For example, we may only want the representation returned if it is more recent than the one we have in cache. Similarly, we may want to instruct the client about how it should cache the representation. This isn't restricted to caching. We may, for example, want to store a new representation of a resource only if it wasn't modified since we first retrieved it.</p> +<p>The data format of a representation is also known as the media type. Some media types are intended for direct rendering to the user, while others are intended for automated processing. The media type is a key component of the REST architecture.</p> +<h2 id="_self_descriptive_messages">Self-descriptive messages</h2> +<p>Messages must be self-descriptive. That means that the data format of a representation must always come with its media type (and similarly requesting a resource involves choosing the media type of the representation returned). If you are sending HTML, then you must say it is HTML by sending the media type with the representation. In HTTP this is done using the content-type header.</p> +<p>The media type is often an IANA registered media type, like <code>text/html</code> or <code>image/png</code>, but does not need to be. Exactly two things are important for respecting this constraint: that the media type is well specified, and that the sender and recipient agree about what the media type refers to.</p> +<p>This means that you can create your own media types, like <code>application/x-mine</code>, and that as long as you write the specifications for it and that both endpoints agree about it then the constraint is respected.</p> +<h2 id="_hypermedia_as_the_engine_of_application_state">Hypermedia as the engine of application state</h2> +<p>The last constraint is generally where services that claim to be RESTful fail. Interactions with a server must be entirely driven by hypermedia. The client does not need any prior knowledge of the service in order to use it, other than an entry point and of course basic understanding of the media type of the representations, at the very least enough to find and identify hyperlinks and link relations.</p> +<p>To give a simple example, if your service only works with the <code>application/json</code> media type then this constraint cannot be respected (as there are no concept of links in JSON) and thus your service isn't RESTful. This is the case for the majority of self-proclaimed REST services.</p> +<p>On the other hand if you create a JSON based media type that has a concept of links and link relations, then your service might be RESTful.</p> +<p>Respecting this constraint means that the entirety of the service becomes self-discoverable, not only the resources in it, but also the operations you can perform on it. This makes clients very thin as there is no need to implement anything specific to the service to operate on it.</p> + + + + + + + + + + + + <nav style="margin:1em 0"> + + <a style="float:left" href="https://ninenines.eu/docs/en/cowboy/2.7/guide/multipart/"> + Multipart requests + </a> + + + + <a style="float:right" href="https://ninenines.eu/docs/en/cowboy/2.7/guide/rest_handlers/"> + REST handlers + </a> + + </nav> + + + + +</div> + +<div class="span3 sidecol"> + + +<h3> + Cowboy + 2.7 + + User Guide +</h3> + +<ul> + + <li><a href="/docs/en/cowboy/2.7/guide">User Guide</a></li> + + + <li><a href="/docs/en/cowboy/2.7/manual">Function Reference</a></li> + + +</ul> + +<h4 id="docs-nav">Navigation</h4> + +<h4>Version select</h4> +<ul> + + + + <li><a href="/docs/en/cowboy/2.7/guide">2.7</a></li> + + <li><a href="/docs/en/cowboy/2.6/guide">2.6</a></li> + + <li><a href="/docs/en/cowboy/2.5/guide">2.5</a></li> + + <li><a href="/docs/en/cowboy/2.4/guide">2.4</a></li> + + <li><a href="/docs/en/cowboy/2.3/guide">2.3</a></li> + + <li><a href="/docs/en/cowboy/2.2/guide">2.2</a></li> + +</ul> + +<h3 id="_like_my_work__donate">Like my work?

+Cowboy does nothing by default. + +To make Cowboy useful, you need to map URIs to Erlang modules that will +handle the requests. This is called routing. + +When Cowboy receives a request, it tries to match the requested host and +path to the configured routes. When there's a match, the route's +associated handler is executed. + +Routes need to be compiled before they can be used by Cowboy. +The result of the compilation is the dispatch rules. + +=== Syntax + +The general structure for the routes is defined as follow. + +[source,erlang] +Routes = [Host1, Host2, ... HostN]. + +Each host contains matching rules for the host along with optional +constraints, and a list of routes for the path component. + +[source,erlang] +Host1 = {HostMatch, PathsList}. +Host2 = {HostMatch, Constraints, PathsList}. + +The list of routes for the path component is defined similar to the +list of hosts. + +[source,erlang] +PathsList = [Path1, Path2, ... PathN]. + +Finally, each path contains matching rules for the path along with +optional constraints, and gives us the handler module to be used +along with its initial state. + +[source,erlang] +Path1 = {PathMatch, Handler, InitialState}. +Path2 = {PathMatch, Constraints, Handler, InitialState}. + +Continue reading to learn more about the match syntax and the optional +constraints. + +=== Match syntax + +The match syntax is used to associate host names and paths with their +respective handlers. + +The match syntax is the same for host and path with a few subtleties. +Indeed, the segments separator is different, and the host is matched +starting from the last segment going to the first. All examples will +feature both host and path match rules and explain the differences +when encountered. + +Excluding special values that we will explain at the end of this section, +the simplest match value is a host or a path. It can be given as either +a `string()` or a `binary()`. + +[source,erlang] +---- +PathMatch1 = "/". +PathMatch2 = "/path/to/resource". + +HostMatch1 = "cowboy.example.org". +---- + +As you can see, all paths defined this way must start with a slash +character. Note that these two paths are identical as far as routing +is concerned. + +[source,erlang] +PathMatch2 = "/path/to/resource". +PathMatch3 = "/path/to/resource/". + +Hosts with and without a trailing dot are equivalent for routing. +Similarly, hosts with and without a leading dot are also equivalent. + +[source,erlang] +HostMatch1 = "cowboy.example.org". +HostMatch2 = "cowboy.example.org.". +HostMatch3 = ".cowboy.example.org". + +It is possible to extract segments of the host and path and to store +the values in the `Req` object for later use. We call these kind of +values bindings. + +The syntax for bindings is very simple. A segment that begins with +the `:` character means that what follows until the end of the segment +is the name of the binding in which the segment value will be stored. + +[source,erlang] +PathMatch = "/hats/:name/prices". +HostMatch = ":subdomain.example.org". + +If these two end up matching when routing, you will end up with two +bindings defined, `subdomain` and `name`, each containing the +segment value where they were defined. For example, the URL +`http://test.example.org/hats/wild_cowboy_legendary/prices` will +result in having the value `test` bound to the name `subdomain` +and the value `wild_cowboy_legendary` bound to the name `name`. +They can later be retrieved using `cowboy_req:binding/{2,3}`. The +binding name must be given as an atom. + +There is a special binding name you can use to mimic the underscore +variable in Erlang. Any match against the `_` binding will succeed +but the data will be discarded. This is especially useful for +matching against many domain names in one go. + +[source,erlang] +HostMatch = "ninenines.:_". + +Similarly, it is possible to have optional segments. Anything +between brackets is optional. + +[source,erlang] +PathMatch = "/hats/[page/:number]". +HostMatch = "[www.]ninenines.eu". + +You can also have imbricated optional segments. + +[source,erlang] +PathMatch = "/hats/[page/[:number]]". + +While Cowboy does not reject multiple brackets in a route, +the behavior may be undefined if the route is under-specified. +For example, this route requires constraints to determine what +is a chapter and what is a page, since they are both optional: + +[source,erlang] +PathMatch = "/book/[:chapter]/[:page]". + +You can retrieve the rest of the host or path using `[...]`. +In the case of hosts it will match anything before, in the case +of paths anything after the previously matched segments. It is +a special case of optional segments, in that it can have +zero, one or many segments. You can then find the segments using +`cowboy_req:host_info/1` and `cowboy_req:path_info/1` respectively. +They will be represented as a list of segments. + +[source,erlang] +PathMatch = "/hats/[...]". +HostMatch = "[...]ninenines.eu". + +If a binding appears twice in the routing rules, then the match +will succeed only if they share the same value. This copies the +Erlang pattern matching behavior. + +[source,erlang] +PathMatch = "/hats/:name/:name". + +This is also true when an optional segment is present. In this +case the two values must be identical only if the segment is +available. + +[source,erlang] +PathMatch = "/hats/:name/[:name]". + +If a binding is defined in both the host and path, then they must +also share the same value. + +[source,erlang] +PathMatch = "/:user/[...]". +HostMatch = ":user.github.com". + +Finally, there are two special match values that can be used. The +first is the atom `'_'` which will match any host or path. + +[source,erlang] +PathMatch = '_'. +HostMatch = '_'. + +The second is the special host match `"*"` which will match the +wildcard path, generally used alongside the `OPTIONS` method. + +[source,erlang] +HostMatch = "*". + +=== Constraints + +After the matching has completed, the resulting bindings can be tested +against a set of constraints. Constraints are only tested when the +binding is defined. They run in the order you defined them. The match +will succeed only if they all succeed. If the match fails, then Cowboy +tries the next route in the list. + +The format used for constraints is the same as match functions in +`cowboy_req`: they are provided as a list of fields which may have +one or more constraints. While the router accepts the same format, +it will skip fields with no constraints and will also ignore default +values, if any. + +Read more about xref:constraints[constraints]. + +=== Compilation + +The routes must be compiled before Cowboy can use them. The compilation +step normalizes the routes to simplify the code and speed up the +execution, but the routes are still looked up one by one in the end. +Faster compilation strategies could be to compile the routes directly +to Erlang code, but would require heavier dependencies. + +To compile routes, just call the appropriate function: + +[source,erlang] +---- +Dispatch = cowboy_router:compile([ + %% {HostMatch, list({PathMatch, Handler, InitialState})} + {'_', [{'_', my_handler, #{}}]} +]), +%% Name, TransOpts, ProtoOpts +cowboy:start_clear(my_http_listener, + [{port, 8080}], + #{env => #{dispatch => Dispatch}} +). +---- + +=== Using persistent_term + +The routes can be stored in `persistent_term` starting from +Erlang/OTP 21.2. This may give a performance improvement when +there are a large number of routes. + +To use this functionality you need to compile the routes, +store them in `persistent_term` and then inform Cowboy: + +[source,erlang] +---- +Dispatch = cowboy_router:compile([ + {'_', [{'_', my_handler, #{}}]} +]), +persistent_term:put(my_app_dispatch, Dispatch), +cowboy:start_clear(my_http_listener, + [{port, 8080}], + #{env => #{dispatch => {persistent_term, my_app_dispatch}}} +). +---- + +=== Live update + +You can use the `cowboy:set_env/3` function for updating the dispatch +list used by routing. This will apply to all new connections accepted +by the listener: + +[source,erlang] +Dispatch = cowboy_router:compile(Routes), +cowboy:set_env(my_http_listener, dispatch, Dispatch). + +Note that you need to compile the routes again before updating. + +When using `persistent_term` there is no need to call this function, +you can simply put the new routes in the storage. diff --git a/docs/en/cowboy/2.7/guide/routing/index.html b/docs/en/cowboy/2.7/guide/routing/index.html new file mode 100644 index 00000000..98d17ed2 --- /dev/null +++ b/docs/en/cowboy/2.7/guide/routing/index.html @@ -0,0 +1,379 @@ +<!DOCTYPE html> +<html lang="en"> + +<head> + <meta charset="utf-8"> + <meta name="viewport" content="width=device-width, initial-scale=1.0"> + <meta name="description" content=""> + <meta name="author" content="Loïc Hoguin based on a design from (Soft10) Pol Cámara"> + + <title>Nine Nines: Routing</title> + + <link href='https://fonts.googleapis.com/css?family=Open+Sans:400,700,400italic' rel='stylesheet' type='text/css'> + <link href="/css/99s.css?r=6" rel="stylesheet"> + + <link rel="shortcut icon" href="/img/ico/favicon.ico"> + <link rel="apple-touch-icon-precomposed" sizes="114x114" href="/img/ico/apple-touch-icon-114.png"> + <link rel="apple-touch-icon-precomposed" sizes="72x72" href="/img/ico/apple-touch-icon-72.png"> + <link rel="apple-touch-icon-precomposed" href="/img/ico/apple-touch-icon-57.png"> + + +</head> + + +<body class=""> + <header id="page-head"> + <div id="topbar" class="container"> + <div class="row"> + <div class="span2"> + <h1 id="logo"><a href="/" title="99s">99s</a></h1> + </div> + <div class="span10"> + + <div id="side-header"> + <nav> + <ul> + <li><a title="Hear my thoughts" href="/articles">Articles</a></li> + <li><a title="Watch my talks" href="/talks">Talks</a></li> + <li class="active"><a title="Read the docs" href="/docs">Documentation</a></li> + <li><a title="Request my services" href="/services">Consulting & Training</a></li> + </ul> + </nav> + <ul id="social"> + <li> + <a href="https://github.com/ninenines" title="Check my Github repositories"><img src="/img/ico_github.png" data-hover="/img/ico_github_alt.png" alt="Github"></a> + </li> + <li> + <a title="Contact me" href="mailto:[email protected]"><img src="/img/ico_mail.png" data-hover="/img/ico_mail_alt.png"></a> + </li> + </ul> + </div> + </div> + </div> + </div> + + +</header> + +<div id="contents" class="two_col"> +<div class="container"> +<div class="row"> +<div id="docs" class="span9 maincol"> + +<h1 class="lined-header"><span>Routing</span></h1> + +<p>Cowboy does nothing by default.</p> +<p>To make Cowboy useful, you need to map URIs to Erlang modules that will handle the requests.

While the router accepts the same format, it will skip fields with no constraints and will also ignore default values, if any.</p> +<p>Read more about <a href="../constraints">constraints</a>.</p> +<h2 id="_compilation">Compilation</h2> +<p>The routes must be compiled before Cowboy can use them.

They can then receive +or send Websocket frames, handle incoming Erlang messages or +close the connection. + +=== Upgrade + +The `init/2` callback is called when the request is received. +To establish a Websocket connection, you must switch to the +`cowboy_websocket` module: + +[source,erlang] +---- +init(Req, State) -> + {cowboy_websocket, Req, State}. +---- + +Cowboy will perform the Websocket handshake immediately.

Because Websocket takes over the connection, +the Websocket protocol handling occurs in a different +process than the request handling. + +This is reflected in the different callbacks Websocket +handlers have. The `init/2` callback is called from the +temporary request process and the `websocket_` callbacks +from the connection process. + +This means that some initialization cannot be done from +`init/2`. Anything that would require the current pid, +or be tied to the current pid, will not work as intended. +The optional `websocket_init/1` can be used instead: + +[source,erlang] +---- +websocket_init(State) -> + erlang:start_timer(1000, self(), <<"Hello!">>), + {ok, State}. +---- + +All Websocket callbacks share the same return values. This +means that we can send frames to the client right after +the upgrade: + +[source,erlang] +---- +websocket_init(State) -> + {[{text, <<"Hello!">>}], State}. +---- + +=== Receiving frames + +Cowboy will call `websocket_handle/2` whenever a text, binary, +ping or pong frame arrives from the client. + +The handler can handle or ignore the frames. It can also +send frames back to the client or stop the connection. + +The following snippet echoes back any text frame received and +ignores all others: + +[source,erlang] +---- +websocket_handle(Frame = {text, _}, State) -> + {[Frame], State}; +websocket_handle(_Frame, State) -> + {ok, State}. +---- + +Note that ping and pong frames require no action from the +handler as Cowboy will automatically reply to ping frames. +They are provided for informative purposes only. + +=== Receiving Erlang messages + +Cowboy will call `websocket_info/2` whenever an Erlang message +arrives. + +The handler can handle or ignore the messages. It can also +send frames to the client or stop the connection. + +The following snippet forwards log messages to the client +and ignores all others: + +[source,erlang] +---- +websocket_info({log, Text}, State) -> + {[{text, Text}], State}; +websocket_info(_Info, State) -> + {ok, State}. +---- + +=== Sending frames + +// @todo This will be deprecated and eventually replaced with a +// {Commands, State} interface that allows providing more +// functionality easily. + +All `websocket_` callbacks share return values. They may +send zero, one or many frames to the client. + +To send nothing, just return an ok tuple: + +[source,erlang] +---- +websocket_info(_Info, State) -> + {ok, State}. +---- + +To send one frame, return the frame to be sent: + +[source,erlang] +---- +websocket_info(_Info, State) -> + {[{text, <<"Hello!">>}], State}. +---- + +You can send frames of any type: text, binary, ping, pong +or close frames. + +You can send many frames at the same time: + +[source,erlang] +---- +websocket_info(_Info, State) -> + {[ + {text, "Hello"}, + {text, <<"world!">>}, + {binary, <<0:8000>>} + ], State}. +---- + +They are sent in the given order. + +=== Keeping the connection alive + +Cowboy will automatically respond to ping frames sent by +the client. They are still forwarded to the handler for +informative purposes, but no further action is required. + +Cowboy does not send ping frames itself. The handler can +do it if required. A better solution in most cases is to +let the client handle pings. Doing it from the handler +would imply having an additional timer per connection and +this can be a considerable cost for servers that need to +handle large numbers of connections. + +Cowboy can be configured to close idle connections +automatically. It is highly recommended to configure +a timeout here, to avoid having processes linger longer +than needed. + +The `init/2` callback can set the timeout to be used +for the connection. For example, this would make Cowboy +close connections idle for more than 30 seconds: + +[source,erlang] +---- +init(Req, State) -> + {cowboy_websocket, Req, State, #{ + idle_timeout => 30000}}. +---- + +This value cannot be changed once it is set. It defaults to +`60000`. + +=== Limiting frame sizes + +Cowboy accepts frames of any size by default. You should +limit the size depending on what your handler may handle. +You can do this via the `init/2` callback: + +[source,erlang] +---- +init(Req, State) -> + {cowboy_websocket, Req, State, #{ + max_frame_size => 8000000}}. +---- + +The lack of limit is historical. A future version of +Cowboy will have a more reasonable default. + +=== Saving memory + +The Websocket connection process can be set to hibernate +after the callback returns. + +Simply add an `hibernate` field to the returned tuple: + +[source,erlang] +---- +websocket_init(State) -> + {[], State, hibernate}. + +websocket_handle(_Frame, State) -> + {[], State, hibernate}. + +websocket_info(_Info, State) -> + {[{text, <<"Hello!">>}], State, hibernate}. +---- + +It is highly recommended to write your handlers with +hibernate enabled, as this allows to greatly reduce the +memory usage. Do note however that an increase in the +CPU usage or latency can be observed instead, in particular +for the more busy connections. + +=== Closing the connection + +The connection can be closed at any time, either by telling +Cowboy to stop it or by sending a close frame. + +To tell Cowboy to close the connection, use a stop tuple: + +[source,erlang] +---- +websocket_info(_Info, State) -> + {stop, State}. +---- + +Sending a `close` frame will immediately initiate the closing +of the Websocket connection. Note that when sending a list of +frames that include a close frame, any frame found after the +close frame will not be sent. + +The following example sends a close frame with a reason message: + +[source,erlang] +---- +websocket_info(_Info, State) -> + {[{close, 1000, <<"some-reason">>}], State}. +---- diff --git a/docs/en/cowboy/2.7/guide/ws_handlers/index.html b/docs/en/cowboy/2.7/guide/ws_handlers/index.html new file mode 100644 index 00000000..9c1b18f4 --- /dev/null +++ b/docs/en/cowboy/2.7/guide/ws_handlers/index.html @@ -0,0 +1,364 @@ +<!DOCTYPE html> +<html lang="en"> + +<head> + <meta charset="utf-8"> + <meta name="viewport" content="width=device-width, initial-scale=1.0"> + <meta name="description" content=""> + <meta name="author" content="Loïc Hoguin based on a design from (Soft10) Pol Cámara"> + + <title>Nine Nines: Websocket handlers</title> + + <link href='https://fonts.googleapis.com/css?family=Open+Sans:400,700,400italic' rel='stylesheet' type='text/css'> + <link href="/css/99s.css?r=6" rel="stylesheet"> + + <link rel="shortcut icon" href="/img/ico/favicon.ico"> + <link rel="apple-touch-icon-precomposed" sizes="114x114" href="/img/ico/apple-touch-icon-114.png"> + <link rel="apple-touch-icon-precomposed" sizes="72x72" href="/img/ico/apple-touch-icon-72.png"> + <link rel="apple-touch-icon-precomposed" href="/img/ico/apple-touch-icon-57.png"> + + +</head> + + +<body class=""> + <header id="page-head"> + <div id="topbar" class="container"> + <div class="row"> + <div class="span2"> + <h1 id="logo"><a href="/" title="99s">99s</a></h1> + </div> + <div class="span10"> + + <div id="side-header"> + <nav> + <ul> + <li><a title="Hear my thoughts" href="/articles">Articles</a></li> + <li><a title="Watch my talks" href="/talks">Talks</a></li> + <li class="active"><a title="Read the docs" href="/docs">Documentation</a></li> + <li><a title="Request my services" href="/services">Consulting & Training</a></li> + </ul> + </nav> + <ul id="social"> + <li> + <a href="https://github.com/ninenines" title="Check my Github repositories"><img src="/img/ico_github.png" data-hover="/img/ico_github_alt.png" alt="Github"></a> + </li> + <li> + <a title="Contact me" href="mailto:[email protected]"><img src="/img/ico_mail.png" data-hover="/img/ico_mail_alt.png"></a> + </li> + </ul> + </div> + </div> + </div> + </div> + + +</header> + +<div id="contents" class="two_col"> +<div class="container"> +<div class="row"> +<div id="docs" class="span9 maincol"> + +<h1 class="lined-header"><span>Websocket handlers</span></h1> + +<p>Websocket handlers provide an interface for upgrading HTTP/1.1 connections to Websocket and sending or receiving frames on the Websocket connection.</p> +<p>As Websocket connections are established through the HTTP/1.1 upgrade mechanism, Websocket handlers need to be able to first receive the HTTP request for the upgrade, before switching to Websocket and taking over the connection.

It uses the HTTP Upgrade mechanism to +establish the connection. + +Websocket connections are fully asynchronous, unlike +HTTP/1.1 (synchronous) and HTTP/2 (asynchronous, but the +server can only initiate streams in response to requests). +With Websocket, the client and the server can both send +frames at any time without any restriction. It is closer +to TCP than any of the HTTP protocols. + +Websocket is an IETF standard. Cowboy supports the standard +and all drafts that were previously implemented by browsers, +excluding the initial flawed draft sometimes known as +"version 0". + +=== Websocket vs HTTP/2 + +For a few years Websocket was the only way to have a +bidirectional asynchronous connection with the server. +This changed when HTTP/2 was introduced. While HTTP/2 +requires the client to first perform a request before +the server can push data, this is only a minor restriction +as the client can do so just as it connects. + +Websocket was designed as a kind-of-TCP channel to a +server. It only defines the framing and connection +management and lets the developer implement a protocol +on top of it. For example you could implement IRC over +Websocket and use a Javascript IRC client to speak to +the server. + +HTTP/2 on the other hand is just an improvement over +the HTTP/1.1 connection and request/response mechanism. +It has the same semantics as HTTP/1.1. + +If all you need is to access an HTTP API, then HTTP/2 +should be your first choice. On the other hand, if what +you need is a different protocol, then you can use +Websocket to implement it. + +=== Implementation + +Cowboy implements Websocket as a protocol upgrade.

It uses the HTTP Upgrade mechanism to establish the connection.</p> +<p>Websocket connections are fully asynchronous, unlike HTTP/1.1 (synchronous) and HTTP/2 (asynchronous, but the server can only initiate streams in response to requests). With Websocket, the client and the server can both send frames at any time without any restriction. It is closer to TCP than any of the HTTP protocols.</p> +<p>Websocket is an IETF standard. Cowboy supports the standard and all drafts that were previously implemented by browsers, excluding the initial flawed draft sometimes known as "version 0".</p> +<h2 id="_websocket_vs_http_2">Websocket vs HTTP/2</h2> +<p>For a few years Websocket was the only way to have a bidirectional asynchronous connection with the server. This changed when HTTP/2 was introduced. While HTTP/2 requires the client to first perform a request before the server can push data, this is only a minor restriction as the client can do so just as it connects.</p> +<p>Websocket was designed as a kind-of-TCP channel to a server. It only defines the framing and connection management and lets the developer implement a protocol on top of it. For example you could implement IRC over Websocket and use a Javascript IRC client to speak to the server.</p> +<p>HTTP/2 on the other hand is just an improvement over the HTTP/1.1 connection and request/response mechanism. It has the same semantics as HTTP/1.1.</p> +<p>If all you need is to access an HTTP API, then HTTP/2 should be your first choice. On the other hand, if what you need is a different protocol, then you can use Websocket to implement it.</p> +<h2 id="_implementation">Implementation</h2> +<p>Cowboy implements Websocket as a protocol upgrade. Once the upgrade is performed from the <code>init/2</code> callback, Cowboy switches to Websocket. Please consult the next chapter for more information on initiating and handling Websocket connections.</p> +<p>The implementation of Websocket in Cowboy is validated using the Autobahn test suite, which is an extensive suite of tests covering all aspects of the protocol. Cowboy passes the suite with 100% success, including all optional tests.</p> +<p>Cowboy's Websocket implementation also includes the permessage-deflate and x-webkit-deflate-frame compression extensions.</p> +<p>Cowboy will automatically use compression when the <code>compress</code> option is returned from the <code>init/2</code> function.</p> + + + + + + + + + + + + <nav style="margin:1em 0"> + + <a style="float:left" href="https://ninenines.eu/docs/en/cowboy/2.7/guide/resource_design/"> + Designing a resource handler + </a> + + + + <a style="float:right" href="https://ninenines.eu/docs/en/cowboy/2.7/guide/ws_handlers/"> + Websocket handlers + </a> + + </nav> + + + + +</div> + +<div class="span3 sidecol"> + + +<h3> + Cowboy + 2.7 + + User Guide +</h3> + +<ul> + + <li><a href="/docs/en/cowboy/2.7/guide">User Guide</a></li> + + + <li><a href="/docs/en/cowboy/2.7/manual">Function Reference</a></li> + + +</ul> + +<h4 id="docs-nav">Navigation</h4> + +<h4>Version select</h4> +<ul> + + + + <li><a href="/docs/en/cowboy/2.7/guide">2.7</a></li> + + <li><a href="/docs/en/cowboy/2.6/guide">2.6</a></li> + + <li><a href="/docs/en/cowboy/2.5/guide">2.5</a></li> + + <li><a href="/docs/en/cowboy/2.4/guide">2.4</a></li> + + <li><a href="/docs/en/cowboy/2.3/guide">2.3</a></li> + + <li><a href="/docs/en/cowboy/2.2/guide">2.2</a></li> + +</ul> + +<h3 id="_like_my_work__donate">Like my work?
