导轨渲染JSON - 会议失去了什么？ [英] Rails Render JSON - Session Lost?

问题描述

我试图做一些Ajax调用到一个控制器，它响应JSON。

i am trying to make some Ajax calls to an controller which responds with JSON.

if session[:user]
  render :json => "Some Data"
else
  render :json => "You are not logged in"
end

第一次这个动作被调用由authed用户一切正常，并会议！[：用户] 是 =零。 第二次，它被称为是零！

The first time this action gets called by an authed user everything is ok and session[:user] is != nil. The second time it gets called it is nil!

因此​​，它似乎像Rails是失去它的会话，只要我做的渲染：JSON 。我想通了，第一个电话轨内将覆盖 * _会议 -cookie一个新的。作为该钢轨的后果不知道最初，authed，会话。

So it seems like rails is loosing it's session as soon as i do render :json. I figured out that within the first call rails overrides the *_session-cookie with a new one. As consequence of that rails doesn't know about the initial, authed, session.

如果我不渲染响应作为JSON一切工作正常。

If i don't render the response as JSON everything works fine.

如何强制导轨设置相同的SessionID以JSON呈现的页面作为正常的看法？

How to force rails to set the same sessionid in JSON rendered pages as in normal views?

推荐答案

经过六天的搜索我终于做到了的：

After six days of searching I finally made it:

好像铁轨破坏，因为缺少 X-CSRF令牌头了会议。我在JQuery中的 ajaxSend 挂钩，现在加入这个标题中：

Seems like rails destroys the session because of the missing X-CSRF-Token Header. I am adding this header now in in the ajaxSend Hook of JQuery:

$(document).ajaxSend(function(e, xhr, options) {
  var sid = $("meta[name='csrf-token']").attr("content");
  xhr.setRequestHeader("X-CSRF-Token", sid);
});

它按预期工作了。

It's working as expected now.
