Rails 3 获取请求引用 [英] Rails 3 get request referrer

问题描述

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

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

http://mysite.com/article/5?type=blah

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?

In the redirect login page, I need access to that URL, anyone know how I can do this?

推荐答案

您可以在控制器中使用 request.referer 或 request.env['HTTP_REFERER'] 来获取引用网址.

You can use request.referer or request.env['HTTP_REFERER'] in your controller to get the referer url.
