Req:header("referer") is current url, not where the request originated

[Caiyun Deng]

Hi!

Req:header("referer") is current url, not where the request originated.

Do i use it by the wrong way?

[Kai Janson]

In afraid that a bit more surrounding code is needed to understand your problem.  The usage is correct.

It is "where the request originated."

Post your code and Req:header()

[Evgeny M]

Maybe you call this in a script/json returning controller? Any javascript file included in a page will have referer equal to the page url.

Indeed, the context in which this is being called is important.  If being checked, for example, from a dynamically generated image (inside a <img> tag), the referer header would end up being the current URL of the page.

AFAIK, the header("http_referer") is working properly, since it's simply passing the request for that header to the underlying server.

I click the link from view/game/game_list.html, My html is:

    <div class="col-sm-{{ col_num }}">

      <div class="thumbnail">

        <a href="/game/subject/{{ game.id }}">

          <img src="/static/img/game_logo/{{ game.id }}.png">

          <div class="text-center">

            <span>{{ game.name }}</span>

          </div>

        </a>

      </div>

    </div>

And the controller's code:

-module(yxq_game_controller, [Req]).

-compile(export_all).

-include("yxq.hrl").  

-include("deps/mysql/src/mysql.hrl").

-include("deps/simple_bridge/include/simple_bridge.hrl").

before_(Action, Arg1, Arg2) ->

    ?TRACE_VAR(Req:header(http_referer)),

    ?TRACE_VAR(Req:header(referer)),

And the print result is:

******

Module: yxq_game_controller, Line: 41, 

My print's "Req : header ( http_referer )" is undefined

******

******

Module: yxq_game_controller, Line: 41, 

My print's "Req : header ( referer )" is "http://localhost:8006/game/subject/1"

11:50:51.680 [notice] Request Method: 'POST', Tokens: []

[can2nac]

post Req:header(), the full headre as it is, do not cut out a part of it.

Req:header() will be "Unhandled Error: error:undef"

I think he means Req:headers(), which should return all headers in the request.

The fact that there's a POST request in there is interesting, and likely the cause of confusion.

The Post must be originating from the original request, because a simple link from an <a href> link will generate a GET request.

Find the source of the post and youll have your culprit. I'd bet some Javascript is doing it on page load.
