答

您可以使用 online_presence 用户$ c>表中的/ code>列，这表示用户当前的Facebook聊天状态。这不是一个万无一失的现在这个用户在线，但它确实有一般目的。此列是一个字符串，其中包含四个可能的值之一：活动， idle ， offline 或错误。查询朋友表与此结果可以产生您请求的结果（在这种情况下，我认为在线是指活动或 idle ）：

You can use the online_presence column of the user table, which gives the user's current Facebook Chat status. This isn't a foolproof "is this user online right now" but it does serve the general purpose as such. This column is a string which has one of four possible values: active, idle, offline, or error. Querying the friend table in conjunction with this can yield the result you requested (in this case I consider "online" to mean active or idle):

SELECT uid FROM user WHERE
  online_presence IN ('active', 'idle')
  AND uid IN (
    SELECT uid2 FROM friend WHERE uid1 = $user_id
  )

更新：

请注意，您需要 user_status 读取用户状态的权限和 user_online_presence 和/或 friends_online_presence 权限对于 online_presence 。

Note that you need the user_status permission to read the user's status and user_online_presence and/or friends_online_presence permissions for the online_presence.
