Ruby on Rails如何获取当前URL？ [英] Ruby on Rails how to get current URL?

问题描述

我尝试使用 request.host ， request.url 获取当前网址，但我有一个网站位于2个网域，因此：

I'm trying to get the current url in rails using request.host, request.url but I have a website that are in 2 domains, so:

当我在 www.example1.com request.host 或.url显示 www.example1.com

when I'm at www.example1.com the request.host or .url show www.example1.com

当我在 www.example2.com request.host 或.url show example1.com
，因为example2正在从example1获取所有内容，并在example2（已解析）

when I'm at www.example2.com the request.host or .url show example1.com because the example2 is getting all content from example1 and showing in the example2(parsed)

中显示request.host得到真正的主机，并且request.url获取主机也
我真的需要获取url在浏览器中不是主机，有人可以帮助吗？

because the request.host get really the host, and request.url getting the host also I'm really need the get the url in the browser don't the host, someone can help?

OB：我使用rails 4和ruby 2
OBs2：request.domain不起作用，只返回.com的url

OBs: I'm using rails 4 and ruby 2 OBs2: request.domain don't works, this return just ".com" of url

推荐答案

request.original_url 

将在rails 4中提供您当前的网址。
