我试图用 C# 为 iPhone 编写一个推送服务器。我有以下代码:
// Create a TCP/IP client socket.
using (TcpClient client = new TcpClient())
{
client.Connect("gateway.sandbox.push.apple.com", 2195);
using (NetworkStream networkStream = client.GetStream())
{
Console.WriteLine("Client connected.");
X509Certificate clientCertificate = new X509Certificate(@"certfile.p12", passwordHere);
X509CertificateCollection clientCertificateCollection = new X509CertificateCollection(new X509Certificate[1] { clientCertificate });
// Create an SSL stream that will close the client's stream.
SslStream sslStream = new SslStream(
client.GetStream(),
false,
new RemoteCertificateValidationCallback(ValidateServerCertificate),
null
);
try
{
sslStream.AuthenticateAsClient("gateway.sandbox.push.apple.com");
}
catch (AuthenticationException e)
{
Console.WriteLine("Exception: {0}", e.Message);
if (e.InnerException != null)
{
Console.WriteLine("Inner exception: {0}", e.InnerException.Message);
}
Console.WriteLine("Authentication failed - closing the connection.");
client.Close();
return;
}
}
等等……
只有我不断收到异常:“对 SSPI 的调用失败,请参阅内部异常”内部异常 - >“收到的消息是意外的或格式错误。”
有谁知道这里出了什么问题?
