Question

我正在用fb api做一些测试。我在两个不同的帐户中执行两个查询。查询是：

SELECT name，friend_count FROM user WHERE uid = me（）

和

选择uid，来自uid in的用户的名字（从朋友那里选择uid1） UID2 =我（））

在我的程序（我在下面列出）中，每个执行的查询都显示返回的行数。在其中一个帐户中，friend_count的值为637，在第二个查询中返回599行。我认为这个结果是正确的，因为某些帐户可能已停用。但是，在另一个帐户中，friend_count的值为3599，但仅返回4行是第二个帐户。我不明白为什么会这样。我是权限，但似乎两个帐户中的一切都是相同的。

下面，我列出了我的代码。每次我想用其他帐户执行时，我都会更改第44行。这一行是auth = vectAuth [0];或者auth = vectAuth [1];我正在使用facebook4j api。

编辑：我使用Graph API（me /？fields = friends）进行了更多测试，我发现对于拥有637位朋友的帐户，我使用api V1.0获得599位朋友，使用api V2.0获得3位朋友。在第二个帐户中，我在两个版本的API中获得了4个朋友。
