Azure ServiceBus FaultTolerantAmqpObject`1' 异常

Question

因此，由于需要 TLS 1.2，我已升级到 Azure.Messaging.ServiceBus 版本 7.1.2，并将我的项目升级到 .NET 4.7.2。我像这样重写了监听器（这是一个预置 windows 服务）BusListener.cs :

public static async Task ReceiveMessagesAsync()
    {   
        await using (ServiceBusClient client = new ServiceBusClient(ConfigurationManager.AppSettings[SERVICE_BUS_CONNECTION_STRING]))
        {
            ServiceBusProcessor processor = client.CreateProcessor(QUEUE_NAME, new ServiceBusProcessorOptions());

            processor.ProcessMessageAsync += MessageHandler;
            processor.ProcessErrorAsync += ErrorHandler;

            await processor.StartProcessingAsync();
        }
    }

我调用 windows 服务 ServiceMain.cs

Task.Run(() => BusListener.ReceiveMessagesAsync());

我在等待大约 10 秒后收到此错误，但从未收到任何消息：

Cannot access a disposed object. Object name: 'FaultTolerantAmqpObject`1'. - at Microsoft.Azure.Amqp.Singleton`1.d__13.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at Azure.Messaging.ServiceBus.Amqp.AmqpConnectionScope.d__54.MoveNext()

我环顾四周，从另一个答案看来是这样的：Service Bus Disposed Object that I could be running into issues due to the method being static, even though this is what I'm following in the Microsoft "how to" guide here: https://docs.microsoft.com/en-us/azure/service-bus-messaging/service-bus-dotnet-get-started-with-queues

我不确定是我写的服务总线部分不正确还是我遗漏了什么？有没有办法通过 ping 或测试连接来更好地了解问题所在？

当您创建 ServiceBusClient 时，它拥有与它创建的任何子对象所使用的服务的连接。通过在这一行中配置客户端：

await using (ServiceBusClient client = new ServiceBusClient(ConfigurationManager.AppSettings[SERVICE_BUS_CONNECTION_STRING]))

您正在关闭您创建的处理器使用的连接。我建议将客户端提升到方法之外，并允许它在应用程序的生命周期内作为单例存在。一般来说，这是我们推荐的管理 Azure 客户端的方法。 （参见：client lifetime）
