Facebook - Getting current user id with app access token

votes

My Facebook tab app, uses the FB.ui send dialog to send invitations to the user's friends to join and collaborate in my app.

enter image description here

Since the send dialog response is just a {success:true} JS Object, I can't tell who the recipients are.

By calling: https://graph.facebook.com/oauth/access_token?client_id=MY_APP_ID&client_secret=MY_APP_SECRET&grant_type=client_credentials

I can get a valid access token, and can query public information of a specific user like so:

https://graph.facebook.com/USER_ID?access_token=MY_APP_ACCESS_TOKEN

Q:How can I get the current user id, without forcing a login ... is it possible?

If you use a Page Tab App, you could access the signed_request as described here: https://developers.facebook.com/docs/reference/login/signed-request/

Upon using the Share Dialog it's not possible AFAIK.
