DynDNS 和无可争议的 badauth 响应

Question

我正在尝试使用 DynDNS API 来验证用户提供的 DynDNS 凭据，以及文档 表示 “badauth”响应 的目的正是那个。
我的想法是，我可以使用用户凭据自动更新，并查找 badauth 响应，并使用它来检测不正确的凭据，这听起来很完美。
问题是我得到的唯一回应是 badauth。当我发送应该很好的凭据时（因为它们当前正在用于登录等），我收到了错误响应。这是我的代码：

   try
   {
     string target = string.Format( "http://{0}:{1}@members.dyndns.org:8245/nic/update?hostname={2}&myip={3}",
      HttpUtility.UrlEncode( DynDnsUserName ), HttpUtility.UrlEncode( DynDnsPassword ), HttpUtility.UrlEncode( DynDnsURL ), ip );
     HttpWebRequest request = WebRequest.Create( target ) as HttpWebRequest;
     request.Method = "GET";
     request.UserAgent = company + " - " + model + " - " + firmware;
     HttpWebResponse response = request.GetResponse() as HttpWebResponse;
     Stream reply = response.GetResponseStream();
     StreamReader readReply = new StreamReader( reply );
     string returnCode = readReply.ReadToEnd();
     Trace.WriteLine( "We've validated the provided DynDNS credentials, response received: " + returnCode );
     return !returnCode.Contains( "badauth" );
   }
   catch (WebException webEx)
   {
     Trace.WriteLine( "WebException thrown: " + webEx.Message );
     if (webEx.Response != null)
     {
      Stream reply = webEx.Response.GetResponseStream();
      StreamReader readReply = new StreamReader( reply );
      Trace.WriteLine( "Actual response: " + readReply.ReadToEnd() );
     }
   }

无论我使用什么凭据，我都会不断收到抛出的 WebException“远程服务器返回错误：(401) 未经授权”，响应正文为 badauth。有什么想法吗？

{0}：{1}@... 不适用于网络请求。

你的目标只是“http://members.dynd....”，你做了类似的事情

NetworkCredential myCredentials = new NetworkCredential(username,passwd);

request.Credentials = myCredentials;
