我一直在尝试基于 Austin Sample 创建一个示例应用程序。首先,我有一个带有示例的 404,我通过调整 App.Config 中的 connectionString 来修复它(我忘了那个,我的错)。现在我创建了第二个接收器,它应该将消息发送到服务总线队列而不是 Azure 表。启动 SampleApplication 和 EventSourceSimulator 时,前两条消息似乎正确传递,但第三条消息显示 404 错误。以下是错误的屏幕截图和我的接收器的类。如果您需要更多信息来帮助我,请告诉我。提前致谢,

{
readonly QueueClient _queueClient;

ServiceBusQueueSink(string errorType, bool storeCtis)
{
_errorType = errorType;
_storeCtis = storeCtis;

qd.MaxSizeInMegabytes = 2048;
qd.DefaultMessageTimeToLive = new TimeSpan(0, 1, 0);

_connectionstring = CloudConfigurationManager.GetSetting("Microsoft.ServiceBus.ConnectionString");
_namespaceManager = NamespaceManager.CreateFromConnectionString(_connectionString);

{
_namespaceManager.CreateQueue(_queueName);
}

更新:我在管理门户的服务总线队列中看不到任何东西,所以我想那里什么也没有。
