Est-ce que quelqu'un sait comment écrire un fournisseur de notifications Apple Push en C #?

Apple avait vraiment de mauvaise documentation sur la façon dont le fournisseur se connecte et communique à leur service (au moment de la rédaction - 2009). Je suis confus au sujet de ce protocole. Si quelqu'un pourrait fournir un exemple C# de la façon dont cela est fait, il serait grandement apprécié.

    De travail exemple de code:

    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();

    J'espère que c'est pertinent (un peu), mais j'ai réussi à créer un pour Java, donc conceptuellement assez similaire à C# (sauf peut-être le SSL trucs, mais ça ne devrait pas être trop difficile à modifier. Ci-dessous est un échantillon de la charge utile du message et de cryptographie de l'installation:

        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();

    }

    Une fois de plus, pas du C#, mais au moins, plus proche que les pauvres ObjC échantillon Apple.

    Le meilleur APNSSharp projet disponible sur Github. Il a travaillé pour moi absolument parfait en seulement quelques minutes!

    Vous pouvez utiliser le PushSharp bibliothèque dans GitHub.

    Je l'utilise dans tous mes projets
