FQL Graph API：互助朋友 [英] FQL Graph API: Mutual Friends

问题描述

我知道你不能得到朋友的朋友，但是可以用计算效率的方式，使用一些查询来获得共同的朋友吗？

I know you can't get friends of friends, but can you get mutual friends using some query, in a computationally efficient manner?

我可以迭代我的朋友们看看他们中的哪一个是有目标的朋友？有没有什么好的方法来获得互惠的朋友？

Could I even iterate through my friends to see which of them is friends with a target? Is there any good way to get Mutual friends?

推荐答案

你可以这样做：

$facebook = new Facebook(array(
  'appId'  => FB_ID,
  'secret' => FB_APP_SECRET,
  'cookie' => true,
));


$fql = "SELECT id FROM profile WHERE id IN (SELECT uid2 FROM friend WHERE uid1=me())";

$response = $facebook->api(array(
'method' => 'fql.query',
'query' =>$fql,
));

这将返回共同的朋友的ID。希望这可以帮助你：）

This will return the id of the mutual friends. Hope this helps you :)

编辑：

如果你想得到你和id之间的共同的朋友= 13245那么你可以这样做：

If you want to get the mutual friends between you and id=13245 then you can do like:

$facebook = new Facebook(array(
  'appId'  => FB_ID,
  'secret' => FB_APP_SECRET,
  'cookie' => true,
));

$fql = "SELECT uid1, uid2 FROM friend WHERE uid1 IN (SELECT uid2 FROM friend WHERE uid1=me() AND uid2 = '13245' ) AND uid2 IN (SELECT uid2 FROM friend WHERE uid1=me())";

$response = $facebook->api(array(
'method' => 'fql.query',
'query' =>$fql,
));

它将返回所有共同的朋友ID。

It will return all mutual friends id.

希望这给你想要的。
