誰かがApple Push Notification ProviderをC＃で書く方法を知っていますか？

Question

Appleは、プロバイダがどのようにサービスに接続して通信しているかについての悪いドキュメントを実際に持っていました（2009年時点）。私はプロトコルについて混乱しています。そこにいる誰かが、これがどのように行われたかのC＃サンプルを提供できれば、非常に感謝しています。

Answer 1

操作コード例：

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

//load certificate 
string certificatePath = @"cert.p12"; 
string certificatePassword = ""; 
X509Certificate2 clientCertificate = new X509Certificate2(certificatePath, certificatePassword); 
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.Tls, true); 
} 
catch (AuthenticationException ex) 
{ 
    client.Close(); 
    return; 
} 

// Encode a test message into a byte array. 
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) 

String deviceId = "DEVICEIDGOESHERE"; 
writer.Write(ToByteArray(deviceId.ToUpper())); 

String payload = "{\"aps\":{\"alert\":\"I like spoons also\",\"badge\":14}}"; 

writer.Write((byte)0); //First byte of payload length; (big-endian first byte) 
writer.Write((byte)payload.Length); //payload length (big-endian second byte) 

byte[] b1 = System.Text.Encoding.UTF8.GetBytes(payload); 
writer.Write(b1); 
writer.Flush(); 

byte[] array = memoryStream.ToArray(); 
sslStream.Write(array); 
sslStream.Flush(); 

// Close the client connection. 
client.Close();

私はこれが適切であることを望みますが、ちょうどJava用のものを作成しましたので、概念的にはC＃と非常に似ています（おそらくSSLのものを除きますが、サンプルメッセージペイロードおよび暗号化設定：

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


    char []passwKey = "<keystorePassword>".toCharArray(); 
    KeyStore ts = KeyStore.getInstance("PKCS12"); 
    ts.load(new FileInputStream("/path/to/apn_keystore/cert.p12"), passwKey); 

    KeyManagerFactory tmf = KeyManagerFactory.getInstance("SunX509"); 
    tmf.init(ts,passwKey); 
    SSLContext sslContext = SSLContext.getInstance("TLS"); 
    sslContext.init(tmf.getKeyManagers(), null, null); 
    SSLSocketFactory factory =sslContext.getSocketFactory(); 
    SSLSocket socket = (SSLSocket) factory.createSocket(hostname,port); // Create the ServerSocket 
    String[] suites = socket.getSupportedCipherSuites(); 
    socket.setEnabledCipherSuites(suites); 
    //start handshake 

    socket.startHandshake(); 


    // Create streams to securely send and receive data to the server 
    InputStream in = socket.getInputStream(); 
    OutputStream out = socket.getOutputStream(); 



    // Read from in and write to out... 
    ByteArrayOutputStream baos = new ByteArrayOutputStream(); 
    baos.write(0); //The command 
    System.out.println("First byte Current size: " + baos.size()); 

    baos.write(0); //The first byte of the deviceId length  
    baos.write(32); //The deviceId length 

    System.out.println("Second byte Current size: " + baos.size()); 

    String deviceId = "<heaxdecimal representation of deviceId"; 
    baos.write(hexStringToByteArray(deviceId.toUpperCase())); 
    System.out.println("Device ID: Current size: " + baos.size()); 


    String payload = "{\"aps\":{\"alert\":\"I like spoons also\",\"badge\":14}}"; 
    System.out.println("Sending payload: " + payload); 
    baos.write(0); //First byte of payload length; 
    baos.write(payload.length()); 
    baos.write(payload.getBytes()); 

    out.write(baos.toByteArray()); 
    out.flush(); 

    System.out.println("Closing socket.."); 
    // Close the socket 
    in.close(); 
    out.close(); 

}

再度、ないC位が、少なくともAppleが提供することが貧弱にObjCサンプルよりも近い
