= cowboy_req:parse_cookies(3)
== Name
cowboy_req:parse_cookies - Parse cookie headers
== Description
[source,erlang]
----
parse_cookies(Req) -> [{Name, Value}]
Name :: binary() %% case sensitive
Value :: binary() %% case sensitive
----
Parse cookie headers.
Alias for link:man:cowboy_req:parse_header(3)[cowboy_req:parse_header(<<"cookie">>, Req)].
When the cookie header is missing, `[]` is returned.
While an empty cookie header is not valid, some clients do
send it. Cowboy will in this case also return `[]`.
== Arguments
Req::
The Req object.
== Return value
The cookies are returned as a list of key/values. Keys and
values are case sensitive binary strings.
== Changelog
* *2.0*: Only the parsed header value is returned, it is no longer wrapped in a tuple.
* *2.0*: Function introduced. Replaces `cookie/2,3` and `cookies/1`.
== Examples
.Look for a specific cookie
[source,erlang]
----
Cookies = cowboy_req:parse_cookies(Req),
{_, Token} = lists:keyfind(<<"token">>, 1, Cookies).
