使用Graph API获取所有Facebook好友
我试图获取“我/朋友”，并且返回的JSON包含的朋友比我的Facebook页面显示的少3个。事实证明，对于那些3，GET“/ [id]”返回false而不是有效的JSON对象，虽然我没有看到任何特殊的关于它们，除了他们可能还没有使用Facebook一段时间。最初我认为这是一个错误但我被告知这是设计的。如果是这种情况，如何通过Graph API获取我当前Fb朋友的完整列表？

我不认为这是原因。我也在努力解决这个问题。使用taggable_friends而不是朋友会带给你的朋友。
重点是facebook上的“朋友”是那些使用你正在使用/正在使用的相同APP的人。
希望它有所帮助。
