如何通过 uid 计算Facebook用户的总朋友数？
How can I count the total friends of a Facebook user by uid?
答
可以查询用户表格中有一个 friend_count 字段。
There is a friend_count field against the user table that you can query.
SELECT friend_count FROM user WHERE uid = me()
只需将您要查询的用户的UID替换为 me（）。
Just replace me() with the UID of the user that you want to query.
