python-openid不提供ax或sreg属性

Question

我终于能够让python-openid对用户进行身份验证，但我无法创建sreg.SRegResponse或ax.FetchResponse，因为它们返回为None。这是来自谷歌应用程序的一个账号，我正在尝试效仿https://github.com/openid/python-openid/tree/master/examples/djopenid的例子。我听说谷歌的OpenID系统有点时髦，需要像Retrieve OpenID AX attributes from Google / Yahoo in Rails这样的一些调整

    response = c.complete(request_args, return_to)

    sreg_response = sreg.SRegResponse.fromSuccessResponse(response)
    ax_response = ax.FetchResponse.fromSuccessResponse(response)

响应肯定是成功的，但我看到了以下错误消息，这可能与此相关：

这是我的设置。

           sreg_request = sreg.SRegRequest(optional=['email', 'nickname'],
                                        required=['dob'])
            auth_request.addExtension(sreg_request)

            # Add Attribute Exchange request information.
            ax_request = ax.FetchRequest()
            # XXX - uses myOpenID-compatible schema values, which are
            # not those listed at axschema.org.
            ax_request.add(ax.AttrInfo('http://schema.openid.net/namePerson',
                                       required=True))
            ax_request.add(ax.AttrInfo('http://schema.openid.net/contact/web/default',
                                       required=False, count=ax.UNLIMITED_VALUES))
            auth_request.addExtension(ax_request)

我在谷歌返回AttributeExchange的schema.openid.net值时遇到了问题。就像你提到的那样，它没有返回任何内容，最糟糕的是，当我第一次编写OpenID处理程序时，它还能正常工作。

一旦我在我的实现中切换到axschema值，它就像一个护身符一样工作。例如：

    URLS = {
      'ax_email': 'http://axschema.org/contact/email',
      'ax_first': 'http://axschema.org/namePerson/first',
    }

    ...

    ax_request = ax.FetchRequest()
    ax_request.add(ax.AttrInfo(URLS['ax_email'], required = True))
    ax_request.add(ax.AttrInfo(URLS['ax_first'], required = True))

    auth_request.addExtension(ax_request)
