在Rails中从Google/Yahoo检索OpenID AX属性

Question

我在我的应用程序中使用rails插件open_id_authentication.这适用于MyOpenID,但是对Google进行身份验证我无法将电子邮件地址作为必需属性的一部分.

据我所知,Google忽略了sreg属性请求,只监听AX架构的电子邮件地址.

这是我的代码:

     def open_id_authentication(openid_url)

       #google only responds to AX for email, so we must provide that also
       authenticate_with_open_id(openid_url, :required => [:nickname, :email, 'http://axschema.org/contact/email']) do |result, identity_url, registration|
        if result.successful?    
         @user = User.find_or_initialize_by_identity_url(identity_url)
         if @user.new_record?            
             unless registration['email'] || registration['http://axschema.org/contact/email']          
                 failed_login "Your OpenID provider didn't send us an email address."
                 return
              end

          #some providers (like Google) won't send a nick name.  We'll use email instead for those
          nick = registration['nickname']
          nick |= registration['email']
          nick |= registration['http://axschema.org/contact/email']

          email = registration['email'];
          email |= registration['http://axschema.org/contact/email']

          @user.login = nick
          @user.email = email
          @user.save(false)
     end
     self.current_user = @user
     successful_login
    else
       failed_login result.message
    end
   end

我的理解是,我提交的电子邮件地址(包括SREG和AX)的要求,我应该能够拉出来的的registration与该响应一起传递实例.

当我使用Google登录时,电子邮件地址将作为"t"传回.

我处理不正确吗？如何从Google获取用户的电子邮件地址？我是否必须通过其他任何环节来支持雅虎？

Answer 1

我自己最终解决了这个问题.找到支持AX架构URL的官方文档并不容易.

这是我发现的:

Google将仅使用AX架构回复电子邮件地址: http://schema.openid.net/contact/email

雅虎将使用这些AX模式回复别名和电子邮件:

http://axschema.org/namePerson/friendly
http://axschema.org/contact/email

所以我需要基本上请求电子邮件地址的所有已知AX架构URL,并希望提供商发送它./耸肩
