问题描述
我想要在线获取用户名单，不需要Facebook SDK.My fql查询如下
$ FQL =SELECT UID，名称，pic_square，online_presence
从用户
其中online_presence IN（ '活性'， '空闲'）
和UID IN（
选择UID2 FROM friend WHERE uid1 = $ user
）;
我的图表URl是
https://graph.facebook.com/fql?q=SELECT UID，名称，pic_square，online_presence FROM用户WHERE online_presence IN（ '活性'， '空闲'）和UID IN（SELECT UID2 FROM朋友WHERE UID1 = 1234）及的access_token = xxxxxxtokenxxxxx&安培;方法= GET
但是，上面的URL返回null数据。
{
data：[
]
}
注意：我的令牌有friends_online_presence权限。我有40位用户在线。
'的div类= h2_lin>解决方案您需要 user_online_presence 或 friends_online_presence 权限查看 online_presence 。 （请参阅）
如果没有这些权限，您将收到 online_presence 作为 null ，这部分 WHERE 将不被任何内容过滤： online_presence IN（'active'，'idle'）
如果您从查询中删除此限制，您将看到具有状态的朋友列表（如果您没有此信息，则为null许可）
I want to Get list of users online without Facebook SDK.My fql Query is as below
$fql = "SELECT uid, name, pic_square, online_presence
FROM user
WHERE online_presence IN ('active', 'idle')
AND uid IN (
SELECT uid2 FROM friend WHERE uid1 = $user
)";
And my graph URl is
https://graph.facebook.com/fql?q=SELECT uid, name, pic_square, online_presence FROM user WHERE online_presence IN ('active', 'idle') AND uid IN (SELECT uid2 FROM friend WHERE uid1 = 1234)&access_token=xxxxxxtokenxxxxx&method=GET
But Above Url returning null data.
{
"data": [
]
}
Note: my token have friends_online_presence permission .I have 40 users online.
解决方案
You need user_online_presence or friends_online_presence permissions to view online_presence. (see http://developers.facebook.com/docs/reference/fql/user)
Without these permissions you'll receive online_presence as null, and nothing will be filtered by this part of WHERE: online_presence IN ('active', 'idle')
If you'll remove this restriction from your query, you'll see the list of friends with their statuses (or nulls if you don't have this permission)
