C#推送信息到APNs的方法
本文实例讲述了C#推送信息到APNs的方法。分享给大家供大家参考。具体实现方法如下：
classProgram
{
publicstaticDateTime?Expiration{get;set;}
publicstaticreadonlyDateTimeDoNotStore=DateTime.MinValue;
privatestaticreadonlyDateTimeUNIX_EPOCH=newDateTime(1970,1,1,0,0,0,DateTimeKind.Utc);

publicconstintDEVICE_TOKEN_STRING_SIZE=64;
publicconstintMAX_PAYLOAD_SIZE=256;

{
stringhostIP="gateway.sandbox.push.apple.com";//
intport=2195;
stringpassword="ankejiaoyu";//
stringcertificatepath="aps_developer_identity.p12";//bin/debug
stringp12Filename=System.IO.Path.Combine(AppDomain.CurrentDomain.BaseDirectory,certificatepath);
certificate=newX509Certificate2(System.IO.File.ReadAllBytes(p12Filename),password,X509KeyStorageFlags.MachineKeySet|X509KeyStorageFlags.PersistKeySet|X509KeyStorageFlags.Exportable);
certificates=newX509CertificateCollection();
certificates.Add(certificate);
TcpClientapnsClient=newTcpClient();
apnsClient.Connect(hostIP,port);
SslStreamapnsStream=newSslStream(apnsClient.GetStream(),false,newRemoteCertificateValidationCallback(validateServerCertificate),newLocalCertificateSelectionCallback(selectLocalCertificate));
try
{
//APNs已不支持SSL3.0
apnsStream.AuthenticateAsClient(hostIP,certificates,System.Security.Authentication.SslProtocols.Tls,false);
}
catch(System.Security.Authentication.AuthenticationExceptionex)
{
Console.WriteLine("error+"+ex.Message);
}
if(!apnsStream.IsMutuallyAuthenticated)
{
Console.WriteLine("error:SslStreamFailedtoAuthenticate！");
}
if(!apnsStream.CanWrite)
{
Console.WriteLine("error:SslStreamisnotWritable!");
}
Byte[]message=ToBytes();
apnsStream.Write(message);
}
publicstaticbyte[]ToBytes()
{

}
byte[]expiry=BitConverter.GetBytes(IPAddress.HostToNetworkOrder(expiryTimeStamp));
byte[]deviceToken=newbyte[DeviceToken.Length/2];
for(inti=0;i<deviceToken.Length;i++)
deviceToken[i]=byte.Parse(DeviceToken.Substring(i*2,2),System.Globalization.NumberStyles.HexNumber);
if(deviceToken.Length!=DEVICE_TOKEN_BINARY_SIZE)
{
Console.WriteLine("Devicetokenlengtherror！");
}
byte[]deviceTokenSize=BitConverter.GetBytes(IPAddress.HostToNetworkOrder(Convert.ToInt16(deviceToken.Length)));
stringstr="{\"aps\":{\"alert\":\"这是测试消息！！\",\"badge\":1,\"sound\":\"anke.mp3\"}}";

returnBuildBufferFrom(notificationParts);
}
privatestaticbyte[]BuildBufferFrom(IList<byte[]>bufferParts)
{

}
returnbuffer;
}
privatestaticboolvalidateServerCertificate(objectsender,X509Certificatecertificate,X509Chainchain,SslPolicyErrorssslPolicyErrors)
