我一直在研究Google身份验证API(AuthSub)...我的问题是，身份验证通过后，如何获取用户的帐户信息(至少是他们的Gmail地址)？
因为当前，我从身份验证过程中得到的只是一个令牌，该令牌使我可以访问我在范围内指定的任何Google服务，但是没有一种简单的方法可以获取用户的登录ID(Gmail地址)。 告诉...
如果可以，我可以通过哪些Google服务访问用户信息？
Google身份验证API是基于令牌的系统，用于对有效用户进行身份验证。 它没有公开任何其他允许将帐户持有者信息返回给授权者的接口。
您可以通过带有斧头扩展名的OpenID API来获取一些数据。 如果您正在使用其他方法进行身份验证，我发现最好的方法是调用https://www-opensocial.googleusercontent.com/api/people/@me/@self，它将获得您的姓名，电子邮件和图片。 进行身份验证时，请确保作用域中包含http://www-opensocial.googleusercontent.com/api。
使用Google AppEngine GData服务，您可以请求用户授予您访问其Google Mail，日历，Picasa等的权限。在此处进行检查。
