Question

我正在尝试在Ruby中的控制器中检索我的网站的完整URL（包括https：//）。我需要它以适合以下代码：

url = ""
uri = URI::parse(url)
id = uri.path.split('/')[2]

感谢。

Answer 1

您应该使用request.original_url

http://api.rubyonrails.org/v5.1/classes/ActionDispatch/Request.html#method-i-original_url

Answer 2

正如Fede所说，你可以在你的控制器request.original_url中使用。此外，如果您在视图中有一些ajax，则可以将其作为数据传递给模型，然后传递给JS中带有window.location.href的控制器。

Answer 3

我终于通过一些帮助和调试找到了它。因为我在一个正在数据库中创建新对象的类中请求URL，所以我不得不使用.asoundrc file pcm.!default{ type asym playback.pcm{type plug slave.pcm "hw:0"} capture.pcm{type plug slave.pcm "hw:1"} } ctl.!default{ type hw card 0 }：

由于我的网址类似于“https://www.example.com/room/4”，因此 id 返回的值为4.

如何检索类中的当前URL？
