`verify_discovery_results` sends a request to openid.claimed_id URL. Anybody can change claimed_id URL but request still will be sent. For example, sending a request to the internal network or localhost: https://myserver/callback?_method=post&openid.claimed_id=http://localhost:3000/do_method..... I think, we must check signature before use any data from the URL

verify_discovery_resultssends a request to openid.claimed_id URL.Anybody can change claimed_id URL but request still will be sent.
For example, sending a request to the internal network or localhost:
https://myserver/callback?_method=post&openid.claimed_id=http://localhost:3000/do_method&.....
And ruby app will send request from its env to the http://localhost:3000/do_method URL.
I think we should check signature before use any data from the URL
