C＃中的Apple推送通知服务器端

我是.net的新手，在C＃中做apn服务器端。 我正在使用下面的代码将消息推送到苹果服务器。

private void pushMessage() { int port = 2195; String deviceID = "4564c705 63b371aa 3811699e 1e4ac3d2 ba592b27 f2a5a613 d25cd035 xx213e54"; String hostname = "gateway.sandbox.push.apple.com"; // TEST //String hostname = "gateway.push.apple.com"; // REAL // @"cert.p12"; String certificatePath = HttpContext.Current.Server.MapPath("Certi.p12"); //X509Certificate2 clientCertificate = new X509Certificate2(certificatePath, ""); X509Certificate2 clientCertificate = new X509Certificate2(System.IO.File.ReadAllBytes(certificatePath), "", X509KeyStorageFlags.MachineKeySet | X509KeyStorageFlags.PersistKeySet | X509KeyStorageFlags.Exportable); X509Certificate2Collection certificatesCollection = new X509Certificate2Collection(clientCertificate); TcpClient client = new TcpClient(hostname, port); // _apnsStream = new SslStream(_apnsClient.GetStream(), false, validateServerCertificate, SelectLocalCertificate); //SslStream sslStream = new SslStream(client.GetStream(), false, new RemoteCertificateValidationCallback(ValidateServerCertificate),null); SslStream sslStream = new SslStream(client.GetStream(), false, validateServerCertificate, SelectLocalCertificate); try { sslStream.AuthenticateAsClient(hostname, certificatesCollection, SslProtocols.Default, false); } catch (Exception e) { throw (e); client.Close(); return; } 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\":\"hello\",\"badge\":0,\"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(); } private string HexStringToByteArray(string p) { throw new NotImplementedException(); } 

在执行中，收到错误，如“对SSPI的调用失败，请参阅内部exception”。

我做错了或错过了。 Windows中是否需要安装任何证书？ 请帮我。

Answer 1

我在PushNotification.class文件中更改了我的代码

 _certificate = string.IsNullOrEmpty(p12FilePassword)? new X509Certificate2(File.ReadAllBytes(p12File)): new X509Certificate2(File.ReadAllBytes(p12File), p12FilePassword); 

同

 _certificate = string.IsNullOrEmpty(p12FilePassword) ? new X509Certificate2(File.ReadAllBytes(p12File)) : new X509Certificate2(File.ReadAllBytes(p12File), p12FilePassword, X509KeyStorageFlags.MachineKeySet); 

Answer 2

所以试试….

 SslStream sslStream = new SslStream(client.GetStream(), false, new RemoteCertificateValidationCallback(ValidateServerCertificate), null); .... public static bool ValidateServerCertificate(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors) { if (sslPolicyErrors == SslPolicyErrors.None) return true; gerarLog("Certificate error: " + sslPolicyErrors); // Do not allow this client to communicate with unauthenticated servers. return false; } public static byte[] HexStringToByteArray(string hexString) { byte[] HexAsBytes = new byte[hexString.Length / 2]; for (int index = 0; index < HexAsBytes.Length; index++) { string byteValue = hexString.Substring(index * 2, 2); HexAsBytes[index] = byte.Parse(byteValue, NumberStyles.HexNumber, CultureInfo.InvariantCulture); } return HexAsBytes; }
