How do I get the current absolute URL in Ruby on Rails?
How can I get the current absolute URL in my Ruby on Rails view?
The request.request_uri only returns the relative URL.
For Rails 3.2 or Rails 4+
You should use request.original_url to get the current URL.
This method is documented at original_url method, but if you're curious, the implementation is:
def original_url
base_url + original_fullpath
end
For Rails 3:
You can write "#{request.protocol}#{request.host_with_port}#{request.fullpath}" , since request.url is now deprecated.
For Rails 2:
You can write request.url instead of request.request_uri . This combines the protocol (usually http://) with the host, and request_uri to give you the full address.
我认为Ruby on Rails 3.0方法现在是request.fullpath 。
你可以使用url_for(:only_path => false)
