Question

有人可以帮我理解为什么我在跳过的队列中收到响应消息（CreditAuthorizationResponse）（mtSubscriber_creditAuthRequest_queue_skipped）？发件人正在按预期收到响应，但他们也会转到跳过的队列。

我创建了以下使用者，除了进入跳过队列的消息之外，它正在按预期工作：

some_foo.many_objects.each(&:destroy)
# ... other code, not knowing about the earlier 'destroy' call(s)
some_foo.many_objects.empty?
# => true

这是我发送请求的地方：

class CreditAuthorizationConsumer : IConsumer<CreditAuthorizationRequest>
{
    private Func<string, Task> _outputDelegate2;

    public CreditAuthorizationConsumer(Func<string, Task> outputDelegate)
    {
        _outputDelegate2 = outputDelegate;
    } 

    public async Task Consume(ConsumeContext<CreditAuthorizationRequest> context)
    {
        await _outputDelegate2($"Received: {context.Message}: {context.Message.CardNumber}");
        await context.RespondAsync<CreditAuthorizationResponse>(new CreditAuthorizationResponse(true));
        await _outputDelegate2($"Sent CreditAuthorizationResponse for card request {context.Message.CardNumber}");
    }
}

这是我正在初始化客户端总线的地方：

private async Task SendCreditAuthRequestAsync(int numberToSend)
{
    for (int i = 0; i < numberToSend; i++)
    {
        var cardNumber = generateCardNumber();
        await SendRequestAsync(new CreditAuthorizationRequest(cardNumber), "mtSubscriber_creditAuthRequest_queue");
        await WriteOutputAsync($"Sent credit auth request for card {cardNumber}.");
    }
}

这是我正在初始化服务端总线的地方：

private void InitializeBus()
{
    _messageBus = Bus.Factory.CreateUsingRabbitMq(sbc =>
    {
        var host = sbc.Host(new Uri(hostUriTextBox.Text), h =>
        {
            h.Username("guest");
            h.Password("guest");
        });

        sbc.ReceiveEndpoint(host, "mtSubscriber_creditAuthResponse_queue", endpoint =>
        {
            endpoint.Handler<CreditAuthorizationResponse>(async context =>
            {
                await WriteOutputAsync($"Received: {context.Message}: {context.Message.IsAuthorized}");
            });
        });

    });
}

Alexey Zimarev是对的 - 我的回复绑定到我的请求队列（除了响应队列）。简单地删除该绑定解决了问题并且它没有回来。谢谢！
