azure - 尝试监听 Azure 事件中心时出现未经授权的错误

Question

我有一个简单的 EventHub 监听器示例代码尝试监听事件中心

public class Program
{



    private const string EventHubConnectionString = "Endpoint=sb://fake.servicebus.windows.net/;SharedAccessKeyName=SendETB;SharedAccessKey=JcvVeX5KsGHfJkPNmdns5jvNYVpB9Wc05jDuMaV3NW8=";
    private const string EventHubName = "myhub";
    private const string StorageContainerName = "my-own-container";
    private const string StorageAccountName = "mystorage";
    private const string StorageAccountKey = "fakeZn8WUV1mcsh0MVbmea/ypxDs+No2tzrhr0kUmjxvA0a0jUxfZ29hHoY/yopVvGLEn/stEQbBEAyjYMX9g==";



    private static readonly string StorageConnectionString = string.Format("DefaultEndpointsProtocol=https;AccountName={0};AccountKey={1}", StorageAccountName, StorageAccountKey);

    public static void Main(string[] args)
    {
        MainAsync(args).GetAwaiter().GetResult();
    }

    private static async Task MainAsync(string[] args)
    {
        Console.WriteLine("Registering EventProcessor...");

        var eventProcessorHost = new EventProcessorHost(
            EventHubName,
            PartitionReceiver.DefaultConsumerGroupName,
            EventHubConnectionString,
            StorageConnectionString,
            StorageContainerName);

        // Registers the Event Processor Host and starts receiving messages
        await eventProcessorHost.RegisterEventProcessorAsync<SimpleEventProcessor>();

        Console.WriteLine("Receiving. Press enter key to stop worker.");
        Console.ReadLine();

        // Disposes of the Event Processor Host
        await eventProcessorHost.UnregisterEventProcessorAsync();
    }
}

}

使用上面提到的代码我得到一个错误。

Error on Partition: 0, Error: Unauthorized access. 'Listen' claim(s) are required to perform this operation. Resource: 'sb://fake.servicebus.windows.net/etbhub/consumergroups/$default/partitions/0'. TrackingId:fakef417d94238ba36d41d32b83341_G9, SystemTracker:gateway5, Timestamp:2020-01-27T22:06:49

错误消息非常具有 self 描述性。确保 SharedAccessKeyName SendETB 允许“监听”权限。您可以在门户网站上进行检查，如下所示。
