Facebook的连接

Question

有没有办法找到，如果两个人都在2-3的水平连接使用Facebook的API（N是精确的）？如果连接，有没有办法让不同的可能路径？ 如果没有，最大深度允许什么？我猜测，我们可以发现至少有2级水平，我们可以手动匹配的好友列表..

Answer 1

是的，这取决于每个人的安全级别和他们接受你的应用程序，你可以使用API​​确定它。

您将需要从应用程序用户read_friendlists权限。

例子：

OK : Me (authd app) -> my friend    -> their friend (authd app) 
OK : Me (authd app) -> my friend (authd app) -> their friend 
OK : Me    -> my friend (authd app) -> their friend 
BAD : Me (authd app) -> my friend    -> their friend 
BAD : Me    -> my friend    -> their friend (authd app) 

并获得多个层次：

OK : Me (authd app) -> my friend    -> their friend (authd app)    -> their friend (authd app)    -> their friend (authd app)    -> their friend (authd app) 

OK : Me    -> my friend    -> their friend (authd app)    -> their friend    -> their friend (authd app)    -> their friend
