Stack Overflow使用什么范围的Google数据？

Question

我想使用谷歌的OAuth登录方法，就像Stack Overflow一样。

但是根据OAuth 2.0 for client-side web applications，scope参数是必需的。

    scope   (required) URL identifying the Google service to be accessed. 
See the documentation for the API you'd like to use for what scope to specify. 
To specify more than one scope, list each one separated with a space.

那么Stack Overflow使用什么作用域呢？

    Stackoverflow.com is asking for some information from your Google Account.
 To see and approve the request, sign in.

Answer 1

StackOverflow使用OpenId。
