Question

我正在使用MassTransit和RaabbitMQ，当我尝试发送消息时，我收到此错误：

rabbitmq://localhost/FilesVersioning => An exception was thrown during Send

我在HttpModule中的Web请求结束时发送消息。

有谁知道这个错误意味着什么？

据我所知，我不会关闭与MassTransit相关的任何内容。

修改

据我所知，它抛出了这个lamda： https://github.com/phatboyg/MassTransit/blob/master/src/Transports/MassTransit.Transports.RabbitMq/OutboundRabbitMqTransport.cs#L51

EDIT2：

我像这样初始化服务总线：

        var _bus = ServiceBusFactory.New(sbc =>
        {
            sbc.UseRabbitMq();
            sbc.ReceiveFrom("rabbitmq://localhost/queue0");
            sbc.ReceiveFrom("rabbitmq://localhost/queue1");
            sbc.ReceiveFrom("rabbitmq://localhost/queue2");
            sbc.Validate();
            sbc.Subscribe(a => a.Handler<Item0>((msg, item) => new Item0Handler().Handle(msg)));
            sbc.Subscribe(a => a.Handler<Item1>((msg, item) => new Item1Handler().Handle(msg)));
            sbc.Subscribe(a => a.Handler<Item2>((msg, item) => new Item2Handler().Handle(msg)));
        });

...我使用_bus来发送和接收消息。我是MassTransient的初学者，所以这个配置也可能是错的......

Answer 1

行。问题似乎是我在一条总线上使用了很多输入队列（sbc.ReceiveFrom()内的许多ServiceBusFactory.New()次呼叫。）

最后，我创建了许多这样的公共汽车：

    var _bus = ServiceBusFactory.New(sbc =>
    {
        sbc.UseRabbitMq();
        sbc.ReceiveFrom("rabbitmq://localhost/queue0");
        sbc.Validate();
        sbc.Subscribe(a => a.Handler<Item0>((msg, item) => new Item0Handler().Handle(msg)));
        sbc.Subscribe(a => a.Handler<Item1>((msg, item) => new Item1Handler().Handle(msg)));
        sbc.Subscribe(a => a.Handler<Item2>((msg, item) => new Item2Handler().Handle(msg)));
    });

    var _bus2 = ServiceBusFactory.New(sbc =>
    {
        sbc.UseRabbitMq();
        sbc.ReceiveFrom("rabbitmq://localhost/queue1");
        sbc.Validate();
        sbc.Subscribe(a => a.Handler<Item0>((msg, item) => new Item0Handler().Handle(msg)));
        sbc.Subscribe(a => a.Handler<Item2>((msg, item) => new Item2Handler().Handle(msg)));
    });
