I notice that the documentation is incorrect about the relevant methods for this callback, I will open a ticket to fix it soon.<div class="im"> On 02/03/2014 07:13 PM, Łukasz Biedrycki wrote: </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div class="im"> Hi, I have a rest handler that accepts POST and PUT requests with “application/json” content type. I have content_types_accepted function defined as follows: content_types_accepted(Req, State) -> {[{‘application/json', from_json}], Req, State}. The problem I have is within a request that has two headers: </div> *Content-type*: application/json *Accept*: application/json With this combination I receive *406*.<div class="im"> You can repeat it with test: http_SUITE.erl: 1072 rest_postonly(Config) -> 1073 Client = ?config(client, Config), 1074 Headers = [ 1075 {<<"content-type">>, <<"text/plain">>}, 1076 {<<"accept">>, <<"text/plain">>} 1077 ], 1078 {ok, Client2} = cowboy_client:request(<<"POST">>, 1079 build_url("/postonly", Config), Headers, "12345", Client), 1080 {ok, 204, _, _} = cowboy_client:response(Client2). My solution to that was to add a content_types_provided function: content_types_provided(Req, State) -> ContentTypes = [{{<<"application">>, <<"json">>, '*'}, to_json}], {ContentTypes, Req, State}. </div> But it is useless as *to_json* callback registered is not called anyhow. Adding *content_types_provided* function is a correct solution in this case?<div class="im"> Or I am missing something here? “Accept” header is not relevant only in case of GET requests?
