Question

我和RabbitMQ一起使用MassTransit。

我在网站上更改了经典示例：

这样：

x.ReceiveEndpoint(host, ConfigurationManager.AppSettings["ServiceQueueName"],
    e => { e.Consumer<RequestConsumer>(); });

与

            var consumer = new RequestConsumerT<string, string>(request =>
                {
                    return "here it is " + request;
                }
            );
            x.ReceiveEndpoint(host, ConfigurationManager.AppSettings["ServiceQueueName"],
                e => { e.Instance(consumer); });

我正在使用RequestConsumerT类作为消费者：

public class RequestConsumerT<TRequest, TResponse> :
    IConsumer<TRequest>
    where TRequest: class
    where TResponse : class
{
    Func<TRequest, TResponse> _implementation;

    public RequestConsumerT(Func<TRequest, TResponse> implementation)
    {
        _implementation = implementation;
    }

    public async Task Consume(ConsumeContext<TRequest> context)
    {
        //await context.RespondAsync<TResponse>(_implementation.Invoke(context.Message));
        context.Respond<TResponse>(_implementation.Invoke(context.Message));
    }

然后，当我提出请求时，消费者没有回答。我的代码出了什么问题，好吗？

谢谢

这是我得到的错误：

这里有一些Rabbitmq经理的截图：

The consumer

Exchanges

MassTransit通用消费者不会消费
