Let me explain my problem, currently I use LinqToTwitter to perform the authorization of a user.
I have the Connect Twitter button on my website, when the user click on it, an ajax request requests the method to perform authorization, the user is redirect to “https://api.twitter.com/oauth/authorize?oauth_token=” and then enter his login and password.
Once it’s done, it is redirect to the urlReferrer of my website and I receive the fields I need like username, userid, …
Then if the UserId of the social network user doesn’t match with any entries of my database I open a popup to ask for his email ( Email is a required field)
Then, once the email has been confirmed by the user, I have to connect him in our website by making an ajax request connectSocialUser(userid, avatar, accessToken).
For Google and Facebook I have put in parameter the access token and then request respectively these two urls :
These two urls give me back the userid and by a simple comparison I can know that the user is the good one and not an usurper.
So my question is :
Is it possible to retrieve the userid of a user from the access token ?
If not how can I make this works?
Thank you a lot!
