request is an ActionDispatch::Request and that subclasses Rack::Request. request是一个ActionDispatch :: Request和子类Rack :: Request。 Rack::Request has a path method that might interest you: Rack :: Request有一个你可能感兴趣的path方法：
<%= request.path %>
If your request.url is http://example.com/where/is?pancakes=house%3F then request.path should be /where/is . 如果您的request.url是http://example.com/where/is?pancakes=house%3F那么request.path应该是/where/is 。
