Facebook的連接

Question

有沒有辦法找到，如果兩個人都在2-3的水平連接使用Facebook的API（N是精確的）？如果連接，有沒有辦法讓不同的可能路徑？ 如果沒有，最大深度允許什麼？我猜測，我們可以發現至少有2級水平，我們可以手動匹配的好友列表..

Answer 1

是的，這取決於每個人的安全級別和他們接受你的應用程序，你可以使用API​​確定它。

您將需要從應用程序用戶read_friendlists權限。

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) 

並獲得多個層次：

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
