Azure 通知中心错误 401

Question

我在设置将推送通知发送到 iOS/Android 设备的控制台应用程序时遇到了一些问题。

错误如下：

Unhandled Exception: System.AggregateException: One or more errors
occurred. ---System.UnauthorizedAccessException: The remote server
returned an error: (401)
Unauthorized..TrackingId:ea158550-8761-41f8-821d-dbcb88fcce56,TimeStamp:18/07/2016

XamarinAzurePushNotification.Server.Program.Main(String[] args) in
B:\Personal Development\Visual Studio
2015\AzurePushNotifications\XamarinAzurePushNotification.Server\Program.cs:line
26

这是我的控制台应用程序代码：

private static void Main(string[] args)
{
    var hub = NotificationHubClient.CreateClientFromConnectionString("Endpoint=sb://ConnectionStringName.servicebus.windows.net/;SharedAccessKeyName=DefaultListenSharedAccessSignature;SharedAccessKey=ConnectionStringKey", "HubName");

    var iOS_alert = "{\"aps\":{\"alert\":\"Hello. This is a iOS notification! Tada!\", \"sound\":\"default\"}}";
    hub.SendAppleNativeNotificationAsync(iOS_alert).Wait();

    var android_alert = "{\"message\": \"Can I interest you in a once in a lifetime push notification?!\", \"title\":\"Ding, dong!\"}";
    hub.SendGcmNativeNotificationAsync(android_alert).Wait();

    Console.WriteLine("MESSAGE SENT");
}

如果有人能帮我解决这个问题，那就太好了。

Answer 1

看起来你正在使用DefaultListenSharedAccessSignature;而是使用DefaultFullSharedAccessSignature。

Answer 2

如果以上任何一个答案都不起作用，请检查服务器/PC 是否配置了正确的日期时间。在我的情况下，在客户端上，服务器的日期时间设置错误，我得到了错误：

错误代码：0x17 System.AggregateException：发生一个或多个错误。 ---> System.UnauthorizedAccessException：远程服务器返回错误：（401）未授权。 ExpiredToken: .TrackingId:4c2cdbg3-e1a8-4240-b963-d6f55e8f2c76_G29,TimeStamp:8/23/2018 8:58:27 AM ---> System.Net.WebException：远程服务器返回错误：（401）未经授权。 在 System.Net.HttpWebRequest.EndGetResponse（IAsyncResult asyncResult） 在 Microsoft.Azure.NotificationHubs.NotificationRequestAsyncResult1.<>c.<GetAsyncSteps>b__26_3(TAsyncResult thisPtr, IAsyncResult r) at Microsoft.Azure.NotificationHubs.Messaging.IteratorAsyncResult1.StepCallback（IAsyncResult 结果） --- 内部异常堆栈跟踪结束 ---

在我发现问题之前非常沮丧。
