Asp.net MassTransit获得消费者的响应
嗨,enybody是否知道如何解决MassTransit中的以下问题:消费者获得请求和响应,但响应不会返回到client.request。方法。我在ASP NET WEB API中创建了项目,并通过IRequestClient接口实现了请求/响应通信:Asp.net MassTransit获得消费者的响应,asp.net,asp.net-web-api,rabbitmq,masstransit,consumer,Asp.net,Asp.net Web Api,Rabbitmq,Masstransit,Consumer,嗨,enybody是否知道如何解决MassTransit中的以下问题:消费者获得请求和响应,但响应不会返回到client.request。方法。我在ASP NET WEB API中创建了项目,并通过IRequestClient接口实现了请求/响应通信: public class RequestResponseCommandProvider<TRequest, TResponse> : IRequestResponseCommandProvider<TRequest, T

我已在Autofac中创建serviceBus作为模块的配置:
public class BusModule : Autofac.Module
{
private readonly string _hostUri;
IEnumerable<IConfigurableConsumer> _consumers;
public BusModule(string hostUri, IEnumerable<IConfigurableConsumer> consumers)
{
_hostUri = hostUri;
_consumers = consumers;
}
protected override void Load(ContainerBuilder builder)
{
builder.RegisterAssemblyTypes(AppDomain.CurrentDomain.GetAssemblies());
builder.Register(r => Bus.Factory.CreateUsingRabbitMq(sfc =>
{
var host = sfc.Host(new Uri(_hostUri), h =>
{
h.Username("guest");
h.Password("guest");
});
if (_consumers != null)
{
foreach (var consumer in _consumers)
{
consumer.Configure(sfc);
}
}
}))
.As<IBus>()
.As<IBusControl>()
.SingleInstance();
builder.RegisterType<RecieveObserver>()
.As<IReceiveObserver>();
}
}
公共类总线模块:自动传真模块

{

使用者由构造函数添加。
将提供程序注入服务:

当我检查RabbitMQ中的队列时,所有消息都如下所示:
我已经看到了Chris Patterson所做的示例RequestResponse,但我在使用依赖注入时遇到了问题。
我将感激你对我所做错事的帮助。。GitHub上还有所有存储库,您可以在其中找到包含此代码但仍然无法工作的简单项目:两个问题:
IBus
第一次被解析时,您将得到一个很长的超时事实上,我们需要启动总线才能收到响应
