如果有注释就好了,我研读了一下才看明白,挺好用:)

拿不到yahoo的数据

这个代码有人维护不?

王炜大哥,通过你提供的方法以上的功能我都实现了,但是现在我有一个问题,就是登陆后怎样判断用户还未退出,比如用google用户来说,用户通过验证登陆到了我的应用程序中(也登陆到了google),但是此时用户退出google登陆,刷新我应用程序,我怎样判断此用户已经退出google要求他从新登陆

您写过facebook接口吗,请问facebook中可以实现获取用户的邮箱吗?

你好王炜
我出现这个错误
不知道如何解决了
https://consent.live.com/pp900/Error.aspx?mkt=zh-CN&ErrorCode=2002

貌似您的google/yahoo的associate过程没有成功。$data['openid.session_type'] = 'DH-SHA1';要设置dh_module dh_gen dh_consumer_public 才可以。

王炜:
您好!我是一名在校学生,对openid比较感兴趣。在进行实践过程中,遇到如下的问题,想请教一下您!
1:在openid2.0协议里边描述:
1.1:收到一个针对"checkid_immediated"模式请求的否定断言的时候,RP应该使用“check_setup”模式构造一个新的认证请求。
1.2:针对及时请求的否定断言满足以下形式:
openid.ns:略
openid.mode:setup_needed
我现在的疑惑:
1:在什么情况下会遇到即时请求的否定断言?
2:您方便的话,可以给我举一个关于终端用户在登录过程中遇到“即时请求的否定断言”这种情况的实例吗?
谢谢您!
