openid_ax_value_email

Google

openid_ext1_value_email

openid_ext1_value_email

很难(不是标准)为每个OpenID提供程序编写单独的代码行. 有这个标准吗?

It is difficult (and not standard) to write separate lines of code for each OpenID provider. Is there a standard for this?

推荐答案

由于 OpenID支持扩展来携带诸如email之类的额外数据，但完全由OpenID提供者决定，要显示哪些数据(如果有的话)，要使用的标识符以及将其放置在扩展名称空间层次结构中的位置.

OpenID supports extensions to carry extra data like email, but it's completely up to the OpenID provider which data to reveal (if any at all), what identifiers to use and where to place them in their extension namespace hierarchy.
