我一个一个发送通知给用户,它需要一段时间。 这是我的代码如何在一个请求中向多个设备(iOS)发送推送通知?
var deviceios = db.Devices;
int port = 2195;
String hostname = "gateway.sandbox.push.apple.com";
string certificatePath = System.Web.HttpContext.Current.Server.MapPath("mypath/cert.p12);
string certificatePassword = "password";
foreach (var item in deviceios)
{
X509Certificate2 clientCertificate = new X509Certificate2(certificatePath, certificatePassword, X509KeyStorageFlags.MachineKeySet);
X509Certificate2Collection certificatesCollection = new X509Certificate2Collection(clientCertificate);
TcpClient client = new TcpClient(hostname, port);
SslStream sslStream = new SslStream(
client.GetStream(),
false,
new RemoteCertificateValidationCallback(ValidateServerCertificate),
null
);
try
{
sslStream.AuthenticateAsClient(hostname, certificatesCollection, System.Security.Authentication.SslProtocols.Default, false);
}
catch (AuthenticationException ex)
{
client.Close();
return;
}
//// Encode a test message into a byte array.
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)
string devicetocken = item.device1;// iphone device token
byte[] b0 = HexString2Bytes(devicetocken);
WriteMultiLineByteArray(b0);
writer.Write(b0);
String payload;
string strmsgbody = "";
int totunreadmsg = 1;
strmsgbody = message;
payload = "{\"aps\":{\"alert\":\"" + strmsgbody + "\",\"badge\":" + totunreadmsg.ToString() + ",\"sound\":\"mailsent.wav\"},\"acme1\":\"bar\",\"acme2\":42}";
writer.Write((byte)0); //First byte of payload length; (big-endian first byte)
byte[] b1 = System.Text.Encoding.UTF8.GetBytes(payload);
writer.Write((byte)b1.Length); //payload length (big-endian second byte)
writer.Write(b1);
writer.Flush();
byte[] array = memoryStream.ToArray();
try
{
sslStream.Write(array);
sslStream.Flush();
}
catch
{
}
client.Close();
发送到多个设备的通知我必须单独发送到每个设备。我可以向设备列表发送通知吗?
尝试使用自己的服务器。在下一次更新中,您将放入一个侦听Web服务器的函数,并在它触发某个事件时指出推送事件。 – devRicher
你有没有考虑过使用ASP.Net SignalR?这是为了这个目的。 –
使用自己的服务器不会改变APN的工作方式。另外使用SignalR与推送通知完全不同。至于这个问题,你是不是打开和关闭每个通知的连接?这将需要很长时间。通知必须逐个发送,但可以在单个连接中发送。你只需要处理错误消息。 –
