C#iPhone推送服务器? [英] C# iPhone push server?
问题描述
我试图用C#为iPhone编写推送服务器。我有以下代码:
Im attempting to write a push server for the iPhone in C#. I have the following code:
// 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;
}
}
ect ....
只有我一直收到异常:
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。
Only I keep receiving a exception: "A call to SSPI failed, see Inner exception" Inner Exception -> "The message received was unexpected or badly formatted."
有没有人知道这里出了什么问题?
Does anyone have any idea whats going wrong here?
推荐答案
弄清楚了。替换了sslStream.AuthenticateAsClient(gateway.sandbox.push.apple.com);使用sslStream.AuthenticateAsClient(gateway.sandbox.push.apple.com,clientCertificateCollection,SslProtocols.Default,false);并在PC上注册证书。
Figured it out. Replaced sslStream.AuthenticateAsClient("gateway.sandbox.push.apple.com"); with sslStream.AuthenticateAsClient("gateway.sandbox.push.apple.com", clientCertificateCollection, SslProtocols.Default, false); And registered the certificates on the PC.
编辑:以下是按要求创建有效负载的代码:
Here is the code for creating a payload as requested:
private static byte[] GeneratePayload(byte [] deviceToken, string message, string sound)
{
MemoryStream memoryStream = new MemoryStream();
// Command
memoryStream.WriteByte(0);
byte[] tokenLength = BitConverter.GetBytes((Int16)32);
Array.Reverse(tokenLength);
// device token length
memoryStream.Write(tokenLength, 0, 2);
// Token
memoryStream.Write(deviceToken, 0, 32);
// String length
string apnMessage = string.Format ( "{{\"aps\":{{\"alert\":{{\"body\":\"{0}\",\"action-loc-key\":null}},\"sound\":\"{1}\"}}}}",
message,
sound);
byte [] apnMessageLength = BitConverter.GetBytes((Int16)apnMessage.Length);
Array.Reverse ( apnMessageLength );
// message length
memoryStream.Write(apnMessageLength, 0, 2);
// Write the message
memoryStream.Write(System.Text.ASCIIEncoding.ASCII.GetBytes(apnMessage), 0, apnMessage.Length);
return memoryStream.ToArray();
} // End of GeneratePayload
