仅当Facebook朋友尚未成为应用程序成员时才邀请他们

Question

I have a rails app doing facebook invite. I use javascript code for that which is all working fine.

I now want a way for the user to only be able to invite friends who are not already members of the app. Is this possible?

Answer 1

我能够使用Facebook提供的“ exclude_ids”解决方案，以从列表中删除一些用户。
