Question

我正在使用RabbitMQ总线和微服务。因为我有2个微服务。我从1服务发布，并尝试在2服务中获取该已发布消息，但我没有得到。这是我的代码。 Startup.cs-发布者，因为我使用的是.net core，而不是放置整个文件，而是放置总线配置

var builder = new ContainerBuilder();
            builder.Register(c =>
            {
                return Bus.Factory.CreateUsingRabbitMq(rmq =>
                {
                    var host = rmq.Host(new Uri("rabbitmq://localhost"), "/", h =>
                    {
                        h.Username("guest");
                        h.Password("guest");
                    });
                    rmq.ExchangeType = ExchangeType.Fanout;
                });

            }).
             As<IBusControl>()
            .As<IBus>()
            .As<IPublishEndpoint>()
            .SingleInstance();

            builder.Populate(services);
            ApplicationContainer = builder.Build();
            var busControl = ApplicationContainer.Resolve<IBusControl>();
            busControl.Start();
            return new AutofacServiceProvider(ApplicationContainer);

控制器发布

_bus.Publish<OrderCompletedEvent>(new { BuyerId = Order.CustomerId.ToString() }).Wait();

消费者启动

var builder = new ContainerBuilder();

            // register a specific consumer
            builder.RegisterType<OrderCompletedEventConsumer>();
            builder.Register(context =>
            {
                var busControl = Bus.Factory.CreateUsingRabbitMq(cfg =>
                {


                    var host = cfg.Host(new Uri("rabbitmq://localhost/"), "/", h =>
                    {
                        h.Username("guest");
                        h.Password("guest");
                    });

                    cfg.ReceiveEndpoint(host, "rabbitmqpocCart" + Guid.NewGuid().ToString(), e =>
                    {
                        e.LoadFrom(context);
                        e.Consumer(() => new OrderCompletedEventConsumer());
                    });
                });

                return busControl;
            })
                .SingleInstance()
                .As<IBusControl>()
                .As<IBus>();
            builder.Populate(services);
            ApplicationContainer = builder.Build();
            var busControl1 = ApplicationContainer.Resolve<IBusControl>();
            busControl1.Start();
            return new AutofacServiceProvider(ApplicationContainer);

消费者服务

    public class OrderCompletedEventConsumer : IConsumer<OrderCompletedEvent>
        {
            public OrderCompletedEventConsumer()
            {
            }

public Task Consume(ConsumeContext<OrderCompletedEvent> context)
        {
            Debug.WriteLine(context.Message.BuyerId);
            await Test();

        }
            public async Task<bool> Test()
            {
                return true;
            }
        }

我已将调试放入“使用方法”中，但没有成功。我错过了什么吗？请帮我。我还注意到，这两种服务都在应用程序启动时开始运行。正确吗？

请给我一些很好的示例链接或文档链接。

谢谢
