Ruby on Rails 3: How to retrieve POST and GET params separately?

问题

I know you can get parameters using params, but the thing is that it merges all parameters whether they were sent via GET or POST:

If you send a request via GET, no problem, the parameters can only be squeezed in the URL.

But if you send a POST request that has a URL like /blabla?foo=bar&foo2=bar2, is there a way to tell the difference between the variables sent via the URL and the variables sent through the actual POST method?

回答1:

Yes, in your controller you can get the GET parameters using request.GET and the POST parameters with request.POST
