Facebook 检查用户是否“喜欢"这一页 [英] Facebook Check if user "Liked" the page

问题描述

我为一家公司制作了几个 Facebook FBML Canvas 页面(Facebook 认为这些是应用程序)，他们要求喜欢"该页面的用户将被重定向到另一个页面，或者页面将使用 AJAX 显示不同的内容.

I made a few Facebook FBML Canvas pages (Facebook considers these to be Applications) for a company, and they requested that users who "Like" the page would be redirected to another page, or the page will display different content with AJAX.

我浏览了 Facebook 开发者文档，但找不到如何操作的线索.

I went through the Facebook Developers Documentation, but I can't find a clue on how to do it.

我确定有人以前做过，有什么建议吗?

I'm sure someone has done it before, any suggestions?
