大致步骤是:

 

1、在facebook 上 创建一个应用程序，可以获得App ID/API Key和App Secret。

 

2、使用URL:

https://www.facebook.com/dialog/oauth?client_id=YOUR_APP_ID&redirect_uri=YOUR_URL&scope=email,read_stream&response_type=token

 

其中YOUR_APP_ID就是你的APPID, YOUR_URL就是你应用程序的URL,Canvas程序就填Canvas的URI, scope就是请求的权限,token表示要返回 accessToken的值

 

这个界面进去就是跟国内的微博应用一样了,是一个申请用户授权的页面,用户点击授权后,facebook会这样请求你的YOUR_URL:

 

http://your_url#accessToken=xxxxxx

 

 

3、拿出accessToken密钥,通过下面的URI获取到用户信息

https://graph.facebook.com/me?access_token=xxxxxxx

 

 

4、各种API：
