首先，需要在facebook创建一个APP，创建方法见https://developers.facebook.com/，APP有一项是填写Domain的，这里填写你website的Domain。（APP是绑定domain的，不能乱填）
然后就可以使用facebook comments plugins。
使用facebook comments plugins，可以在页面中插入facebook comments。
生成code方法：https://developers.facebook.com/docs/plugins/comments
例如：有一个页面是http://www.example.com/ ，在这个页面中插入以下代码便可以使用comments plugings。
