namespace WebApplication1 
{ 
    public partial class _Default : System.Web.UI.Page 
    { 
     protected void Page_Load(object sender, EventArgs e) 
     { 

     } 

     protected void btnPush_Click(object sender, EventArgs e) 
     { 
      pushMessage(txtDeviceID.Text.Trim(), txtPayload.Text.Trim()); 
     } 


     public void pushMessage(string deviceID, string Mesaj) 
     { 

      int port = 2195; 
      String hostname = "gateway.push.apple.com"; 

      String certificatePath = HttpContext.Current.Server.MapPath("new_dev_cert.p12"); 
      X509Certificate2 clientCertificate = new X509Certificate2(System.IO.File.ReadAllBytes(certificatePath), "taxmann"); 
      X509Certificate2Collection certificatesCollection = new X509Certificate2Collection(clientCertificate); 

      TcpClient client = new TcpClient(hostname, port); 
      SslStream sslStream = new SslStream(client.GetStream(), false, new RemoteCertificateValidationCallback(ValidateServerCertificate), null); 

      try 
      { 
       sslStream.AuthenticateAsClient(hostname, certificatesCollection, SslProtocols.Ssl3, false); 

       MemoryStream memoryStream = new MemoryStream(); 
       BinaryWriter writer = new BinaryWriter(memoryStream); 
       writer.Write((byte)0); //The command 
       writer.Write((byte)0); //The first byte of the deviceId length (big-endian first byte) 
       writer.Write((byte)32); //The deviceId length (big-endian second byte) 

       writer.Write(HexStringToByteArray(deviceID.ToUpper())); 
       String payload = "{\"aps\":{\"alert\":\"" + Mesaj + "\",\"badge\":1,\"sound\":\"default\"}}"; 
       writer.Write((byte)0); 
       writer.Write((byte)payload.Length); 
       byte[] b1 = System.Text.Encoding.UTF8.GetBytes(payload); 
       writer.Write(b1); 
       writer.Flush(); 
       byte[] array = memoryStream.ToArray(); 
       sslStream.Write(array); 
       sslStream.Flush(); 
       client.Close(); 
       lblResponse.Text = "Sucess.."; 
      } 
      catch (System.Security.Authentication.AuthenticationException ex) 
      { 
       client.Close(); 
       lblResponse.Text = ex.Message; 
      } 
      catch (Exception e) 
      { 
       client.Close(); 
       lblResponse.Text = e.Message; 
      } 
     } 

     // The following method is invoked by the RemoteCertificateValidationDelegate. 
     public static bool ValidateServerCertificate(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors) 
     { 
      if (sslPolicyErrors == SslPolicyErrors.None) 
       return true; 
      else // Do not allow this client to communicate with unauthenticated servers. 
       return false; 
     } 

     private static byte[] HexStringToByteArray(String DeviceID) 
     { 
      //convert Devide token to HEX value. 
      byte[] deviceToken = new byte[DeviceID.Length/2]; 
      for (int i = 0; i < deviceToken.Length; i++) 
       deviceToken[i] = byte.Parse(DeviceID.Substring(i * 2, 2), System.Globalization.NumberStyles.HexNumber); 

      return deviceToken; 
     } 
    } 
} 

以上是我发送通知后端的源代码。我的代码调试成功并获取消息。但我无法在iPhone上获取通知。

我跟随此http://blog.serverdensity.com/how-to-build-an-apple-push-notification-provider-server-tutorial/。我不知道问题在哪里。你能帮我解决这个问题吗？

通过本教程，它解释了从开始到结束所需的一切，并且完美地工作。它解释了如何设置服务器端和iOS设备上的所有内容，以及如何在开发人员门户中整理所有证书。
