问题
I have gone through wiki on SignalR and still can't figure out how to do Forms authentication with SignalR. I'd like to invoke a call to a hub (or persistent connection) with username/password and be able to return a redirect to an authenticated page, along with setting forms authentication cookie.
回答1:
Don't do forms auth through SignalR. Do it outside of SignalR (as you would normally) and then you can check to make sure incoming calls, and subscribers to your hub are authenticated.
