Rails 3 get request referrer
提问by Johnny Klassy
I'm using Rails 3.0.9, Ruby 1.9.2, Devise 1.3.4 and has a need in Devise session new view to access the request url parameters although I see this as a general Rails request handling question. Essentially, a request is made to a Devise authenticated resource which redirects the user to the login screen. In the login view, I need access to the request url, eg, this is the request url called in the beginning
我正在使用 Rails 3.0.9、Ruby 1.9.2、Devise 1.3.4，并且需要在 Devise 会话新视图中访问请求 url 参数，尽管我认为这是一个通用的 Rails 请求处理问题。本质上，向 Devise 认证资源发出请求，该请求将用户重定向到登录屏幕。在登录视图中，我需要访问请求 url，例如，这是开头调用的请求 url
http://mysite.com/article/5?type=blah
In the redirect login page, I need access to that URL, anyone know how I can do this?
在重定向登录页面中，我需要访问该 URL，有人知道我该怎么做吗？

You can use request.refereror request.env['HTTP_REFERER']in your controller to get the referer url.
您可以在控制器中使用request.referer或request.env['HTTP_REFERER']来获取引用网址。

I have just found out that WEBrick handles request.referrerincorrectly. But don't worry. Unicorn handles it right. I did't test that on other servers. You should check this with yours. I don't think that you use WEBrick as a production server.
我刚刚发现 WEBrick错误地处理request.referrer。不过别担心。独角兽处理得很好。我没有在其他服务器上测试过。你应该和你的一起检查一下。我不认为您将 WEBrick 用作生产服务器。
