Access LogedIn user ID on Facebook page?

Question

Here I use a signed request on facebook:

http://developers.facebook.com/docs/authentication/signed_request/

Here According to the document in the json object, the following field:

"user", "algorithm", "Issued_at", "User ID", "Oauth_token", "Expires", "application data", "Page", profile_id

In my code here, I get the json object successfully, but I missed " user_id ", this is what I missed here.

Thanks for the offer..

Answer 1

The Facebook documentation page you link to says:

"If the user has not authorized your application, your application will be transferred only to a subset of the above information .

Answer 2

You should be able to receive some information, such as userid, like, etc., without authorizing the application.

I managed to get it to work. See my answer to this post. Only for facebook fans with asp.net c # sdk
