我一個一個發送通知給用戶,它需要一段時間。 這是我的代碼如何在一個請求中向多個設備(iOS)發送推送通知?
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();
發送到多個設備的通知我必須單獨發送到每個設備。我可以向設備列表發送通知嗎?
嘗試使用自己的服務器。在下一次更新中,您將放入一個偵聽Web服務器的函數,並在它觸發某個事件時指出推送事件。 – devRicher
你有沒有考慮過使用ASP.Net SignalR?這是爲了這個目的。 –
使用自己的服務器不會改變APN的工作方式。另外使用SignalR與推送通知完全不同。至於這個問題,你是不是打開和關閉每個通知的連接?這將需要很長時間。通知必須逐個發送,但可以在單個連接中發送。你只需要處理錯誤消息。 –
