推荐答案

您必须检查名称空间.例如，服务器可能返回openid.ns.ax = http://openid.net/srv/ax/1.0，这意味着以openid.ax开头的所有内容都与AX扩展有关".
但是也可能是openid.ns.qwerty = http://openid.net/srv/ax/1.0，然后所有以openid.qwerty开头的内容都将与扩展名相关.

You must check namespaces. For example, the server may return openid.ns.ax = http://openid.net/srv/ax/1.0, and that would mean "everything that starts with openid.ax relates to the AX extension".
But it could be openid.ns.qwerty = http://openid.net/srv/ax/1.0 as well, and then everything that starts with openid.qwerty would be related to the extension.

您的代码必须读取那些名称空间，并使用这些名称空间定义的别名.阅读规范以获取更多信息.

Your code must read those namespaces and use aliases as defined by those. Read specifications for more information.
