有谁知道如何编写C＃的苹果推送通知服务提供者？ [英] Does anyone know how to write an Apple Push Notification Provider in C#?

问题描述

苹果真的有关于如何提供连接和他们的服务进行通信糟糕的文档。我感到困惑的协议。如果有人在那里可以提供的这是如何做到一个C＃示例，这将大大AP preciated。

Apple really has bad documentation about how the provider connects and communicates to their service. I am confused about the protocol. If anyone out there could provide a C# sample of how this is done, it would be greatly appreciated.

推荐答案

工作code例如：

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();
