Pushsharp 苹果通知调用 SSPI 失败错误

我正在使用 PushSharp 在 C# 中发送 Apple 推送通知，我有我的生产 .pem 文件及其密码。下面是我的代码片段。我总是收到此错误..

"A call to SSPI failed, see inner exception. ---> System.ComponentModel.Win32Exception: The message received was unexpected or badly formatted-" 

OR

"System.IO.IOException: Authentication failed because the remote party has closed the transport stream."

我尝试了网络中几乎所有可用的代码。甚至尝试了 MoonAPNS 但同样的错误，对于自定义脚本也收到此 SSPI 失败错误。我使用相同的 .pem 文件并运行 php 脚本从同一服务器向 APN 发送推送通知，它有效。

var push = new PushBroker();
var appleCert = File.ReadAllBytes(Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "ck.pem"));
 push.RegisterAppleService(new ApplePushChannelSettings(false, appleCert, "pwd")); 
 push.QueueNotification(new AppleNotification()
                                           .ForDeviceToken("XXXXXXXXXXXXXXX")
                                           .WithAlert("Hello World!")
                                           .WithBadge(7)
                                           .WithSound("sound.caf"));


                LogManager.Info("Waiting for Queue to Finish..");
                push.StopAllServices();

请帮忙 提前致谢

我认为你的 c# 可能不正确，要验证，而不是使用 .pem，你可以尝试使用下面的代码作为测试使用你的 p12 证书...

    Boolean bsandbox = true;
    string p12fileName =AppDomain.CurrentDomain.BaseDirectory + "yourCert.p12";
    string p12password = "1234";

    string deviceID1 = "2909b25e0c699b2dc4864b4b9f719e67aac7e0fab791a72a086ffb788ba28f6a"; //
    string msg = "This is the message sent at : ";
    string alert = "Hello world at " + DateTime.Now.ToLongTimeString();
    int badge = 1;
    string soundstring = "default";
    var payload1 = new NotificationPayload(deviceID1, alert, badge, soundstring);
    payload1.AddCustom("custom1", msg); 

    var notificationList = new List<NotificationPayload> { payload1 };



    var push = new PushNotification(bsandbox, p12fileName, p12password);

    var rejected = push.SendToApple(notificationList);`
