[英]How to get list of online friends using FQL with facebook API?
I have got my friends list after getting logging in on facebook using Facebook connect Java script client API. 在使用Facebook连接Java脚本客户端API登录Facebook后,我收到了我的好友列表。 I want list of my friends that are online at given time.
我想要在给定时间在线的朋友列表。
You can use the online_presence
column of the user
table, which gives the user's current Facebook Chat status. 您可以使用
user
表的online_presence
列,该列提供用户当前的Facebook聊天状态。 This isn't a foolproof "is this user online right now" but it does serve the general purpose as such. 这不是一个万无一失的“这个用户现在在线”,但它确实可以满足一般用途。 This column is a string which has one of four possible values:
active
, idle
, offline
, or error
. 此列是一个字符串,它具有四个可能值之一:
active
, idle
, offline
或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
): 与此一起查询
friend
表可以产生您请求的结果(在这种情况下,我认为“在线”表示active
或idle
):
SELECT uid FROM user WHERE
online_presence IN ('active', 'idle')
AND uid IN (
SELECT uid2 FROM friend WHERE uid1 = $user_id
)
UPDATE: 更新:
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
. 请注意,您所需要的
user_status
权限读取用户的状态和user_online_presence
和/或friends_online_presence
权限的online_presence
。
