问题
Rephrased, is it possible to use the Facebook Open Graph API to display a user's full name and profile picture to other site members who are not Facebook friends with the user?
回答1:
Yes; users' first name, last name and profile picture are publicly available. You can retrieve them from the Graph API (along with other information they have made available) by calling:
https://graph.facebook.com/[user_id_or_name]
This will return a JSON string containing the relevant information.
Enjoy! :)
