获取电子邮件地址从OpenID提供与DotNetOpenAuth

问题描述

我不能在 GetExtension 法的电子邮件地址返回，但它包含在谷歌（我与测试OP）发回的url我的。

I can't get the email address returned in GetExtension method, but it is included in the url that Google (the OP I'm testing with) sends back to me.

if (Page.IsPostBack)
{
    using (var openid = new OpenIdRelyingParty())
    {
        var request = openid.CreateRequest(Request.Form["openid_identifier"]);

        var fetch = new FetchRequest();
        fetch.Attributes.Add(new AttributeRequest(WellKnownAttributes.Contact.Email, true));

        request.AddExtension(fetch);

        request.RedirectToProvider();
    }
}
else
{
    using (var openid = new OpenIdRelyingParty())
    {
        var response = openid.GetResponse();
        if (response != null)
        {
            switch (response.Status)
            {
                case AuthenticationStatus.Authenticated:
                    var claimsResponse = response.GetExtension<FetchRequest>();
                    break;
                case AuthenticationStatus.Canceled:
                    //this.loginCanceledLabel.Visible = true;
                    break;
                case AuthenticationStatus.SetupRequired:
                    //this.loginFailedLabel.Visible = true;
                    break;

                // We don't need to handle SetupRequired because we're not setting
                // IAuthenticationRequest.Mode to immediate mode.
                ////case AuthenticationStatus.SetupRequired:
                ////    break;
            }
        }
    }
}

任何人都知道出了什么问题？

Anyone knows what's wrong?

推荐答案

请尝试以下code：

switch (response.Status)
 {
     case AuthenticationStatus.Authenticated:
         var fetch = response.GetExtension<FetchResponse>();
         string email = String.Empty; 
         if (fetch != null)
         {
            email =  fetch.GetAttributeValue(WellKnownAttributes.Contact.Email);
         }  
        break;
    //...
}
