解决方案
如果您的应用程序已实施Facebook Canvas应用程序，则可以使用Facebook Web应用程序。
invitable_friends API仅适用于
的游戏使用Graph API 2.0版的Facebook Canvas应用程序实现。
画布是在桌面和笔记本电脑上将您的应用程序或游戏直接放在
Facebook.com上的框架。
注意：你会发现你的游戏的文档，他们的意思是你的游戏或你的应用程序。

解决方案
You can only get notifications on Facebook web application if your app has a Facebook Canvas app implemented.
The invitable_friends API is only available for games that have a Facebook Canvas app implementation using version 2.0 of the Graph API.
Check here the full documentation
Canvas is a frame in which to put your app or game directly on Facebook.com on desktops and laptops.
Note: In the documentation you will find "your game", they mean "your game or your app".
