使用RabbitMQ进行masstransit：为什么消息在响应时自动移到*** _ skipped队列

Question

UCITY.API请求发送到UCITY.USER的“ ucity_us_mobilephonecomplete”队列并接收消息，但Masstransit自动将其移至跳过队列

但其他队列工作正常

跳过的队列它做什么工作感谢您的回答

Answer 1

UCIT.API代码

//execute request
public async Task<ResultOpenUserLogin> MobilephoneComplete(AuthenticationIdentity authenticationIdentity, ArguUserMobilephoneComplete arguUserMobilephoneComplete)
    {
        var response = await UserMobilephoneCompleteRequest.Client.Request(new UserMobilephoneCompleteRequest(CorrelationId)
        {
            DeviceType = authenticationIdentity.DeviceType,
            IdUser = authenticationIdentity.IdUser,
            Mobilephone = arguUserMobilephoneComplete.Mobilephone,
            Passcode = arguUserMobilephoneComplete.Passcode
        });// the request timeout
        if (response.Code != 200)
        {
            throw new UCException(response.Code, response.Message);
        }
        return new ResultOpenUserLogin()
        {
            Token = response.Token,
            UserInfoCompleted = !string.IsNullOrWhiteSpace(response.Mobilephone)
        };
    }


//UserMobilephoneCompleteRequest class detail
[RabbitMqUri(VirtualHost = "ucity_us", Queue = "ucity_us_mobilephonecomplete")]
public class UserMobilephoneCompleteRequest : BaseRequest, IMobilephoneCompleteRequest
{
    public UserMobilephoneCompleteRequest(Guid? correlationId) : base(correlationId)
    {

    }
    public int DeviceType { get; set; }

    public int IdUser { get; set; }

    public string Mobilephone { get; set; }

    public string Passcode { get; set; }

    public static IRequestClient<IMobilephoneCompleteRequest, IAuthenticationResponse> Client
    {
        get
        {
            return _requestClient;
        }
    }

    private static IRequestClient<IMobilephoneCompleteRequest, IAuthenticationResponse> _requestClient
    {
        get; set;
    }

    public override void CreateClient(IBusControl busControl, Uri address)
    {
        _requestClient = busControl.CreateRequestClient<IMobilephoneCompleteRequest, IAuthenticationResponse>(address, TimeSpan.FromSeconds(10));
    }
}

UCIT.USER代码

//these codes work well
 [RabbitMqUri(VirtualHost = "ucity_us", Queue = "ucity_us_mobilephonecomplete")]
public class MobilephoneCompleteConsumer : BaseConsumer<MobilephoneCompleteConsumer>, IConsumer<IMobilephoneCompleteRequest>
{
    public async Task Consume(ConsumeContext<IMobilephoneCompleteRequest> context)
    {
        var dispatch = new UserDispatch(context.Message.CorrelationId);
        IBaseResponseModel response = null;
        try
        {
            response = await dispatch.MobilephoneComplete(context.Message);
        }
        catch (UCException ucEx)
        {
            response = new AuthenticationResponse(context.Message.CorrelationId)
            {
                Code = ucEx.Code,
                Message = ucEx.Message
            };
        }
        catch (Exception ex)
        {
            response = new AuthenticationResponse(context.Message.CorrelationId)
            {
                Code = (int)EnumErrorStatus.UserError,
                Message = ex.Message
            };
            Console.WriteLine(Newtonsoft.Json.JsonConvert.SerializeObject(ex));
        }
        await context.RespondAsync(response);
    }
}

更改此方法以使用正确的响应类型，而不是基本接口。

public async Task Consume(ConsumeContext<IMobilephoneCompleteRequest> context)
{
    var dispatch = new UserDispatch(context.Message.CorrelationId);
    try
    {
        var response = await dispatch.MobilephoneComplete(context.Message);
        return context.RespondAsync(response);
    }
    catch (UCException ucEx)
    {
        var response = new AuthenticationResponse(context.Message.CorrelationId)
        {
            Code = ucEx.Code,
            Message = ucEx.Message
        };
        return context.RespondAsync(response);
    }
    catch (Exception ex)
    {
        var response = new AuthenticationResponse(context.Message.CorrelationId)
        {
            Code = (int)EnumErrorStatus.UserError,
            Message = ex.Message
        };
        Console.WriteLine(JsonConvert.SerializeObject(ex));
        return context.RespondAsync(response);
    }
}

对我来说，同样的问题。 解决问题的第二天，原因似乎是针对当前程序集使用Autofac注册方法，例如：

builder.RegisterConsumers(Assembly.GetExecutingAssembly());

使用以下代码（ 每个消费者的显式注册 ）解决了绑定问题：

builder.RegisterType<YouConsumerHandler>();
