Question

我正在使用iOS向asp.net设备发送推送通知。我已成功发送通知（未收到任何错误）。但设备没有收到任何通知。我已成功发送通知（从服务器端）。

 public  void iphonpushnotification(string deviceid)
    {
        string devicetocken =deviceid;//  iphone device token
        int port = 2195;
        String hostname = "gateway.sandbox.push.apple.com";
        //String hostname = "gateway.push.apple.com";

     //   string certificatePath = Server.MapPath("E:\\Certificates.p12");
        string certificatePath = "E:\\pushNotification.p12";

        string certificatePassword = "abc123";

        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, SslProtocols.Default, false);
        }
        catch (AuthenticationException ex)
        {
            Console.WriteLine("Authentication failed");
            client.Close();
          //  Request.SaveAs(Server.MapPath("Authenticationfailed.txt"), true);
            return;
        }

请帮帮我。谢谢你提前

Answer 1

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo 
{
        NSLog(@"%@", userInfo);
}

- (void)application:(UIApplication *)application didFailToRegis[enter image description here][1]terForRemoteNotificationsWithError:(NSError
    *)error 
{
        NSLog(@"Did Fail to Register for Remote Notifications");
        NSLog(@"%@, %@", error, error.localizedDescription);     
}

你需要：

1）沙盒测试帐户

2）使用沙盒帐户登录设备

3）关于功能中的PushNotification

Answer 2

这不是确切的答案。可能它会帮助您调试。

在注册远程通知时，请检查didRegisterForRemoteNotificationsWithDeviceToken和didFailToRegisterForRemoteNotificationsWithError。这将帮助您检查设备是否已成功添加或注册时是否有任何错误。

pushnotification没有使用asp.net到达ios设备？
