web-services - 使用 C# 作为服务器端的黑莓推送通知

Question

1. 我正在尝试使用 C# Web 服务在黑莓中发送推送通知，但我面临的问题是它返回异常“远程服务器返回错误：（404）未找到。”。根据 RIM 标准，所有信息都是正确的，所以请尽快帮助我。

    [WebMethod]
   public bool push(string notification)
   {
       bool success = true;
       byte[] bytes = Encoding.ASCII.GetBytes("Hello");
   
       Stream requestStream = null;
       HttpWebResponse HttpWRes = null;
       HttpWebRequest HttpWReq = null;
   
   
       String BESName = "cp****.pushapi.eval.blackberry.com";
       try
       {
           //http://<BESName>:<BESPort>/push?DESTINATTION=<PIN/EMAIL>&PORT=<PushPort>&REQUESTURI=/
           // Build the URL to define our connection to the BES.
           string httpURL = "https://" + BESName +  "/push?DESTINATION=2B838E45&PORT=32721&REQUESTURI=/";
   
           //make the connection
           HttpWReq = (HttpWebRequest)WebRequest.Create(httpURL);
           HttpWReq.Method = ("POST");
           //add the headers nessecary for the push
           HttpWReq.ContentType = "text/plain";
           HttpWReq.ContentLength = bytes.Length;
           // ******* Test this *******
           HttpWReq.Headers.Add("X-Rim-Push-Id", "2B838E45" + "~" + DateTime.Now); //"~" +pushedMessage +
           HttpWReq.Headers.Add("X-Rim-Push-Reliability", "application-preferred");
           HttpWReq.Headers.Add("X-Rim-Push-NotifyURL", ("http://" + BESName + "2B838E45~Hello~" + DateTime.Now).Replace(" ", ""));
   
           // *************************
           HttpWReq.Credentials = new NetworkCredential("Username", "Password");
   
           requestStream = HttpWReq.GetRequestStream();
           //Write the data from the source
           requestStream.Write(bytes, 0, bytes.Length);
   
           //get the response
           HttpWRes = (HttpWebResponse)HttpWReq.GetResponse();
   
           var pushStatus = HttpWRes.Headers["X-RIM-Push-Status"];
   
           //if the MDS received the push parameters correctly it will either respond with okay or accepted
           if (HttpWRes.StatusCode == HttpStatusCode.OK || HttpWRes.StatusCode == HttpStatusCode.Accepted)
           {
               success = true;
           }
           else
           {
               success = false;
           }
           //Close the streams
   
           HttpWRes.Close();
           requestStream.Close();
       }
       catch (System.Exception)
       {
           success = false;
       }
   
       return success;
   }
   

Answer 1

当我尝试上面的代码时，我得到了同样的错误。代替

String BESName = "cp****.pushapi.eval.blackberry.com";

和

String BESName = "cpxxx.pushapi.eval.blackberry.com/mss/PD_pushRequest";

并确保您在此处提供正确的用户名和密码：

HttpWReq.Credentials = new NetworkCredential("username", "password");

我得到了成功 = true;

然而，即使上面的代码执行成功，我仍然没有在黑莓设备上看到推送消息。
