Subject: 我看到有人说facebook不能回private message? 你试过这个没有？
http://stackoverflow.com/questions/7201859/posting-reply-to-inbox-message
我看了很多关于reply direct message的帖子，根据下图所示的error message，虽然理论上说把app加到facebook的whitelist是可行的，但没有一个帖子上有这样做成功的solution。
我刚找到Facebook处理direct message的formal 做法：把user 定向到对话框，填to 和message内容，如下图所示
定向user到dialog的更多内容：https://developers.facebook.com/docs/reference/dialogs/send/
Note: Facebook messages is a channel for user-to-user communication, and not for applications to send messages to their users, or encourage users to spam their friends. In general, applications on Facebook should use Requests when communicating in game status (its your turn), inviting people to use an application, or sending messages to multiple people. You should offer the Send Dialog in situations when a user might otherwise send an email.
