python-openid不提供ax或sreg属性

Question

我终于成功让python-openid认证用户了，但我却无法创建sreg.SRegResponse或ax.FetchResponse，因为它们返回的结果是None。这是从一个Google Apps账户来的，我正在尝试按照这个链接上的示例进行操作。我听说Google的OpenID系统有点奇怪，可能需要一些调整，比如从Google / Yahoo获取OpenID AX属性。

    response = c.complete(request_args, return_to)

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

虽然响应确实返回的是SUCCESS，但我看到以下错误信息，可能和这个有关：

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)

我在使用谷歌时遇到了问题，它没有返回schema.openid.net的值用于属性交换。就像你提到的，它返回的是None，最糟糕的是，当我最初写我的OpenID处理程序时，这个功能是可以正常工作的。

但当我在我的实现中切换到axschema的值时，一切都顺利了。比如：

    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)
