ruby-on-rails – 从Rails中的Google / Yahoo检索OpenID AX属性

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

我的理解是我根据需要提交了电子邮件地址(sreg和AX),我应该能够将它们从与响应一起传递的注册实例中提取出来.

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？
