From 88227898edd26a823d0942fc7226adb61a20cb5d Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Lo=C3=AFc=20Hoguin?= Date: Mon, 13 Jun 2016 13:23:22 +0200 Subject: Merge static_world and web_server examples The new example is called file_server and it's basically the same as web_server was. The name is clearer than the original, all examples being "Web servers". The new example is also tested and the test suite has been refactored a little. --- examples/web_server/src/directory_handler.erl | 47 --------------------------- 1 file changed, 47 deletions(-) delete mode 100644 examples/web_server/src/directory_handler.erl (limited to 'examples/web_server/src/directory_handler.erl') diff --git a/examples/web_server/src/directory_handler.erl b/examples/web_server/src/directory_handler.erl deleted file mode 100644 index 7af67ba..0000000 --- a/examples/web_server/src/directory_handler.erl +++ /dev/null @@ -1,47 +0,0 @@ -%% Feel free to use, reuse and abuse the code in this file. - -%% @doc Directory handler. --module(directory_handler). - -%% REST Callbacks --export([init/2]). --export([allowed_methods/2]). --export([resource_exists/2]). --export([content_types_provided/2]). - -%% Callback Callbacks --export([list_json/2]). --export([list_html/2]). - -init(Req, Paths) -> - {cowboy_rest, Req, Paths}. - -allowed_methods(Req, State) -> - {[<<"GET">>], Req, State}. - -resource_exists(Req, {ReqPath, FilePath}) -> - case file:list_dir(FilePath) of - {ok, Fs} -> {true, Req, {ReqPath, lists:sort(Fs)}}; - _Err -> {false, Req, {ReqPath, FilePath}} - end. - -content_types_provided(Req, State) -> - {[ - {{<<"application">>, <<"json">>, []}, list_json}, - {{<<"text">>, <<"html">>, []}, list_html} - ], Req, State}. - -list_json(Req, {Path, Fs}) -> - Files = [[ <<(list_to_binary(F))/binary>> || F <- Fs ]], - {jsx:encode(Files), Req, Path}. - -list_html(Req, {Path, Fs}) -> - Body = [[ links(Path, F) || F <- [".."|Fs] ]], - HTML = [<<"Index", - "">>, Body, <<"\n">>], - {HTML, Req, Path}. - -links(<<>>, File) -> - ["", File, "
