苹果推送通知反馈服务不起作用

Question

我正在开发一个使用 Apple 推送通知的 iPhone 应用程序。在 iPhone 端一切都很好，在服务器端我遇到了问题。通知发送正确，但是当我尝试查询反馈服务以获取已卸载应用程序的设备列表时，我总是得到零结果。我知道我应该获得一个结果，因为该应用程序已从我的一台测试设备上卸载。 24 小时或更长时间后，我仍然没有收到反馈服务的结果。

有什么想法吗？有谁知道反馈服务需要多长时间才能识别出我的应用程序已从我的测试设备上卸载？

注意：我的设备上还有另一个推送通知应用程序，因此我知道我的应用程序不是唯一的应用程序。

代码 - C#：

    public static string CheckFeedbackService(string certaName, string hostName)
    {
        SYLogger.Log("Check Feedback Service Started");
        ServicePointManager.ServerCertificateValidationCallback = new RemoteCertificateValidationCallback(ValidateServerCertificate);
         // Create a TCP socket connection to the Apple server on port 2196
        TcpClient tcpClientF = null;
        SslStream sslStreamF = null;
        string result = string.Empty;
         //Contect to APNS& Add the Apple cert to our collection
        X509Certificate2Collection certs = new X509Certificate2Collection { GetServerCert(certaName) };
        //Set up
        byte[] buffer = new byte[38];
        int recd = 0;
        DateTime minTimestamp = DateTime.Now.AddYears(-1);
        // Create a TCP socket connection to the Apple server on port 2196
        try
        {
            using (tcpClientF = new TcpClient(hostName, 2196))
            {
                SYLogger.Log("Client Connected  ::" + tcpClientF.Connected);
                // Create a new SSL stream over the connection
                sslStreamF = new SslStream(tcpClientF.GetStream(), true,ValidateServerCertificate);
                // Authenticate using the Apple cert
                sslStreamF.AuthenticateAsClient(hostName, certs, SslProtocols.Default, false);
                SYLogger.Log("Stream Readable ::" + sslStreamF.CanRead);
                SYLogger.Log("Host Name ::"+hostName);
                SYLogger.Log("Cert Name ::" + certs[0].FriendlyName);

                if (sslStreamF != null)
                {
                    SYLogger.Log("Connection Started");

                            //Get the first feedback
                            recd = sslStreamF.Read(buffer, 0, buffer.Length);
                            SYLogger.Log("Buffer length ::" + recd);
                            //Continue while we have results and are not disposing
                            while (recd > 0)
                            {

                                        SYLogger.Log("Reading Started");
                                            //Get our seconds since 1970 ?

                                            Array.Copy(buffer, 0, bSeconds, 0, 4);
                                            //Check endianness
                                            if (BitConverter.IsLittleEndian)
                                                    Array.Reverse(bSeconds);

                                            //Make sure we have a good feedback tuple
                                            if (deviceToken.Length == 64 && Timestamp > minTimestamp)
                                            {
                                                SYLogger.Log("Feedback " + deviceToken);

Answer 1

您是否尝试向已卸载的应用程序发送推送通知？据我了解，反馈服务仅发送推送通知发送失败的通知。

Answer 2

卸载后一分钟，您将收到反馈。
