Facebook应用程序（计数朋友注册） [英] Facebook application ( count friends registered )

问题描述

使用JS SDK进行Facebook，有没有办法计算也正在使用我的应用程序的朋友（当前登录用户）的数量？我在网上发现这个查询

  SELECT uid FROM user 
 WHERE user.uid IN（SELECT uid2 FROM friend WHERE uid1 = ？）
 AND is_app_user = 1 
  

但我不明白，我不知道该用什么代替'？'

提前感谢！

解决方案

它检索由？指定的用户的朋友的 uid ，这也是您的

所以，而不是？只是把当前用户的id。

有关以下详细信息：用户和朋友 fql表

Using JS SDK for facebook, is there a way to count number of friends (of currently logged in user) that are also using my application ?? I found this query online

SELECT uid FROM user 
WHERE user.uid IN (SELECT uid2 FROM friend WHERE uid1 = ?) 
AND is_app_user = 1

But I don't understand it, and I don't know what to put instead of '?'

Thanks in advance!

解决方案

It retrieves uid of friends of the user, specified by ?, that are also users of your application.

So instead of ? just put the current user's id.
