C#에 Apple Push Notification 제공자를 작성하는 방법은 무엇입니까?

Question

애플은 실제로 제공자가 자신의 서비스와 연결하고 의사 소통하는 방법에 대한 나쁜 문서를 가지고 있었다 (글을 쓰는 시점 - 2009). 나는 프로토콜에 대해 혼란스러워합니다. C#에서 어떻게 이루어 집니까?

Answer 1

작업 코드 예 :

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();

나는 이것이 관련성이 있기를 바랍니다 (약간) 그러나 Java를 위해 하나를 성공적으로 만들었으므로 C#과 개념적으로 매우 유사합니다 (아마도 SSL 물건을 제외하고는 수정하기가 너무 어렵지 않아야합니다. 아래는 샘플 메시지 페이로드 및 암호화 설정 :

    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();

}

다시 한번, C#이 아니라 Apple이 제공하는 열악한 OBJC 샘플보다 적어도 가깝습니다.
