EasyNetQ 未确认收到的消息

Question

连接并从 RabbitMQ 接收消息后，它们不会从队列中删除。

每次连接时，我都会收到相同的消息，而且只有一条。

using(bus = RabbitHutch.CreateBus("host=localhost"))
{
    bus.Receive<MyMessage>("my-queue", message => Console.WriteLine("MyMessage: {0}", message.Text));
}

Answer 1

如 Connecting to RabbitMQ 中所述，创建 Bus 的单个实例并在整个应用程序中使用它。

我确定了以下程序：

创建应用程序范围内的总线实例
可选地，将其作为单例添加到依赖项注入中
开始收听消息
注册以在应用程序关闭后处理总线

这是简化的 Startup.cs，其中包含相关片段作为演示代码：

public class Startup
{

    // This will be your application instance
    IBus bus;

    public void ConfigureServices(IServiceCollection services)
    {  
        // Create, assign the Bus, and add it as Singleton to your application
        bus = RabbitHutch.CreateBus("host=localhost");
        // now you can easyly inject in your components
        services.AddSingleton(bus);
    }

    public void Configure(IHostApplicationLifetime lifetime)
    {
        // Start receiving messages from the queue
        bus.Receive<MyMessage>("my-queue", message => Console.WriteLine("MyMessage: {0}", message.Text));

        // Hook your custom shutdown the the lifecycle
        lifetime.ApplicationStopping.Register(OnShutdown);
    }
    private void OnShutdown()
    {
        // Dispose the Bus
        bus.Dispose();
    }
}
