C#中的Apple推送通知服务器端 [英] Apple push notification server side in C#

问题描述

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.

I'm new to .net and doing apn server side in C#. I'm using below code to push the messages to apple server.

    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();
    }

在执行过程中，出现类似对 SSPI 的调用失败，请参阅内部异常"的错误.

In execution, getting error like "A call to SSPI failed, see inner exception".

我在这里做错了或错过了.windows下需要安装证书吗?请帮帮我.

I'm doing any wrong or missed here. Any certificate installation is required in windows? Please help me.

推荐答案

我更改了 PushNotification.class 文件中的代码

I changed my code in PushNotification.class file

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

与

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