omniauth

问题 I'm building a Rails web app. I use OmniAuth for authentication. I would like to provide API access but only after the user has authenticated themselves with OAuth (via twitter mainly).

Thanks 回答1: You can use request.env['omniauth.origin'] . See https://github.com/intridea/omniauth/wiki/Saving-User-Location 回答2: I see two options

Now, I want to use omniauth to authenticate a particular project with Twitter, Facebook, what have you.

问题 I'm using OmniAuth with Rails 3.1.4 and I'm trying to allow already authenticated users to associate multiple OpenID providers with their account. As an unauthenticated user, signing in with OpenID works fine.
