DotNetOpenId - 打開Id獲取一些數據

Question

我在一個新網站上使用OpenId，並試圖獲取有關用戶的一些基本信息，請參閱下面的代碼。爲什麼下面的allways是空的？

var myData = response.GetExtension<ClaimsResponse>(); 

和主代碼

[System.Web.Mvc.AcceptVerbs(HttpVerbs.Get)] 
    public ActionResult LogOn() 
    { 
     var openid = new OpenIdRelyingParty(); 
     IAuthenticationResponse response = openid.GetResponse(); 

     if (response != null) 
     { 
      switch (response.Status) 
      { 
       case AuthenticationStatus.Authenticated: 
        FormsAuthentication.RedirectFromLoginPage(
         response.ClaimedIdentifier, false); 
        var myData = response.GetExtension<ClaimsResponse>(); 
        break; 
       case AuthenticationStatus.Canceled: 
        ModelState.AddModelError("loginIdentifier", 
         "Login was cancelled at the provider"); 
        break; 
       case AuthenticationStatus.Failed: 
        ModelState.AddModelError("loginIdentifier", 
         "Login failed using the provided OpenID identifier"); 
        break; 
      } 
     } 



     return View("Register"); 
    } 

    [System.Web.Mvc.AcceptVerbs(HttpVerbs.Post)] 
    public ActionResult LogOn(string loginIdentifier) 
    { 
     if (!Identifier.IsValid(loginIdentifier)) 
     { 
      ModelState.AddModelError("loginIdentifier", 
         "The specified login identifier is invalid"); 
      return View(); 
     } 
     else 
     { 
      var openid = new OpenIdRelyingParty(); 
      IAuthenticationRequest request = openid.CreateRequest(
       Identifier.Parse(loginIdentifier)); 

      // Require some additional data 
      request.AddExtension(new ClaimsRequest 
      { 
       Email = DemandLevel.Request, 
       FullName = DemandLevel.Request 
      }); 

      return request.RedirectingResponse.AsActionResult(); 
     } 
    }
