向所有Facebook好友发送自定义消息

Question

与video we made in 2010一样，今年我们又一次做了一个新年快乐视频，其中包含我们所有Facebook和非Facebook好友的名字。

在2010年，我们有一个自定义应用程序，用于在我们每个朋友的墙上贴上一个自定义消息，如“亲爱的XXX，祝您新年快乐，这部影片在1分24秒出现“。

今年我们也想做同样的事情，也就是发布一个自定义的消息来向我们的每个朋友展示特定的信息，但是我们注意到Facebook在墙上和私人消息上张贴有限制。

我们可能会使用的GreaseMonkey/Javascript和对话框API脚本中使用我们的应用程序，但我们仍然担心收到一些安全警告。

那么这个项目是否可行？我们的朋友喜欢我们每年都在做的视频。

一个确认：试图通过直接Send Dialog API销售线索（在发送大约60条消息之后）发送消息到来自Facebook服务器端的错误（错误500，甚至空白页）。

的工作方式，以达致这是

1. 尝试通过直接Feed Dialog API送饲料的消息，
2. 测试如果可能的话或做的，
3. 如果没有成功（时间轴是被用户阻止），通过Send Dialog API发送正常消息。

在所有情况下，必须有对话URL的redirect_uri参数，该参数必须指向应用程序拥有的URL。所以app_id也是强制性的。

这样，你不会发送太多“正常”的信息，因为没有很多人阻挡他们的墙，因此你的信息没有被阻止。

以下是一个示例的GreaseMonkey/TamperMonkey代码：
