Question

我使用以下代码进行推送通知。

public void PushNotificationIOS(string message, string registrationKey)
{

    string deviceID = registrationKey; 
    int port = 2195;
    String hostname = System.Configuration.ConfigurationManager.AppSettings["HostName"];//"gateway.sandbox.push.apple.com";
    string certPath = string.Empty;
    certPath = System.Configuration.ConfigurationManager.AppSettings["CertificatePath"] + System.Configuration.ConfigurationManager.AppSettings["Cer
    String certificatePath = System.Web.HttpContext.Current.Server.MapPath(certPath);
    string certPassword = System.Configuration.ConfigurationManager.AppSettings["CertificatePassword"];
    TcpClient client = new TcpClient(hostname, port);
    try
    {

        X509Certificate2 clientCertificate = new X509Certificate2(System.IO.File.ReadAllBytes(certificatePath), certPassword);
        X509Certificate2Collection certificatesCollection = new X509Certificate2Collection(clientCertificate);
        SslStream sslStream = new SslStream(client.GetStream(), false, new RemoteCertificateValidationCallback(ValidateServerCertificate), null);
        sslStream.AuthenticateAsClient(hostname, certificatesCollection, SslProtocols.Tls, false);
        MemoryStream memoryStream = new MemoryStream();
        BinaryWriter writer = new BinaryWriter(memoryStream);
        writer.Write((byte)0);
        writer.Write((byte)0);
        writer.Write((byte)32);
        writer.Write(StringToByteArray(deviceID.ToUpper()));
        String payload = "{\"aps\":{\"alert\":\"" + message + "\",\"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();
    }
    catch (System.Security.Authentication.AuthenticationException ex)
    {

        client.Close();
    }

}

我收到以下错误身份验证失败，因为远程方已关闭传输流。在Trace上，我得到了以下

System.Net.Security.SslState.CheckThrow(Boolean authSucessCheck)
   at System.Net.Security.SslState.get_SecureStream()
   at System.Net.Security.SslStream.Write(Byte[] buffer)

我尝试了各种帖子中提到的所有内容，但无法解决问题。

确保证书有效＆amp;没有损坏。您可以重新生成证书以确定无效。

尝试提供SecurityProtocolType的所有选项，例如：

sslStream.AuthenticateAsClient(hostname, certificatesCollection, SecurityProtocolType.Tls12 | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls, false);

SecurityProtocolType.Tls12可以协商传输层安全性1.1或向下，但请尝试所有选项以确保。

有关SecurityProtocolType的更多详情，请参阅：
