Question

我在设置控制台应用程序时会遇到一些问题，该应用程序会向iOS / Android设备发送推送通知。

错误显示如下：

Unhandled Exception: System.AggregateException: One or more errors

以下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");
}

如果有人能帮我一把，那就太棒了。

Answer 1

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

如果以上任何答案均无效，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，并且出现错误：

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）未经授权。 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） at Microsoft.Azure.NotificationHubs.NotificationRequestAsyncResult 1.<>c.<GetAsyncSteps>b__26_3(TAsyncResult thisPtr, IAsyncResult r) at Microsoft.Azure.NotificationHubs.Messaging.IteratorAsyncResult 1.StepCallback（IAsyncResult结果） ---内部异常堆栈跟踪的结尾---

非常沮丧，直到我发现问题。
