问题描述
我必须使用Python发布消息，然后使用Masstransit（.Net核心应用程序）使用它。
为了进行测试，我创建了一个控制台应用程序，以使用Azure.ServiceBuss库生成消息。 使用者是ServiceBus的Masstransit实现。
当我使用控制台应用程序将消息发送到队列时，Masstransit无法使用它。 我知道互操作性，必须发送给Masstransit的所有标头才能使用消息，但是我无法使使用者工作。
生产者：
namespace Masstransit.MultipleBus.ServiceBus.Models.Commands
{
class Program
{
const string ServiceBusConnectionString = "connstring";
const string QueueName = "topic";
static IQueueClient queueClient;
public static async Task Main(string[] args)
{
queueClient = new QueueClient(ServiceBusConnectionString,QueueName);
// Send messages.
await SendMessagesAsync();
Console.WriteLine("ENVIoU");
Console.ReadKey();
await queueClient.CloseAsync();
}
private static async Task SendMessagesAsync()
{
try
{
while (true)
{
string messageBody = JsonConvert.SerializeObject(new EnviarExemploPocAzureServiceBusCommand(
NewId.NextGuid(),NewId.NextGuid(),new Proposta()
)
{
Headers = new Dictionary<string,object>() { },Host = new HostInfo()
});
var message = new Message(Encoding.UTF8.GetBytes(messageBody));
Console.WriteLine($"Enviando mensagem: {messageBody}");
await queueClient.SendAsync(message);
Console.WriteLine("Enviado. Enviar outro?");
Console.ReadKey();
}
}
catch (Exception exception)
{
Console.WriteLine($"{DateTime.Now} :: Exception: {exception.Message}");
}
}
}
}
我要发送的课程：
namespace Masstransit.MultipleBus.ServiceBus.Models.Commands
{
public class EnviarExemploPocAzureServiceBusCommand
{
public EnviarExemploPocAzureServiceBusCommand(Guid msgid,Guid convId,Proposta msg)
{
MessageId = msgid.ToString();
ConversationId = convId.ToString();
MessageType = new[]
{
"urn:message:Masstransit.MultipleBus.ServiceBus.Models.Commands:Proposta"
};
Message = msg;
SourceAddress = "";
DestinationAddress = "sb://organization.servicebus.windows.net/topic";
}
public string DestinationAddress { get; set; }
public string MessageId { get; set; }
public string ConversationId { get; set; }
public string SourceAddress { get; set; }
public HostInfo Host { get; set; }
public IDictionary<string,object> Headers { get; set; }
public Proposta Message { get; set; }
public string[] MessageType { get; set; }
}
public class Proposta
{
public Proposta()
{
Nome = "TESTE 2";
AcaoId = 2;
Mensagem = "TESTE 2";
}
public string Nome { get; set; }
public int AcaoId { get; set; }
public string Mensagem { get; set; }
}
public class HostInfo
{
public HostInfo()
{
MachineName = "NOTEXXXXX";
ProcessName = "iisexpress";
ProcessId = 34188;
Assembly = "Masstransit.MultipleBus";
AssemblyVersion = "1.0.0.0";
FrameworkVersion = "3.1.5";
MasstransitVersion = "7.0.2.0";
OperatingSystemVersion = "Microsoft Windows NT 10.0.19041.0";
}
public string MachineName { get; set; }
public string ProcessName { get; set; }
public int ProcessId { get; set; }
public string Assembly { get; set; }
public string AssemblyVersion { get; set; }
public string FrameworkVersion { get; set; }
public string MasstransitVersion { get; set; }
public string OperatingSystemVersion { get; set; }
}
}
消息在ServiceBus中排队：
{
"DestinationAddress": "sb://organization.servicebus.windows.net/topic","MessageId": "00010000-0faa-0009-6939-08d854e183aa","ConversationId": "00010000-0faa-0009-69f0-08d854e183aa","SourceAddress": "","Host": {
"MachineName": "NOTEXXXXX","ProcessName": "iisexpress","ProcessId": 32608,"Assembly": "Masstransit.MultipleBus","AssemblyVersion": "1.0.0.0","FrameworkVersion": "3.1.5","MasstransitVersion": "7.0.2.0","OperatingSystemVersion": "Microsoft Windows NT 10.0.19041.0"
},"Headers": {
},"Message": {
"nome": "TESTE 2","acaoId": 2,"mensagem": "TESTE 2"
},"MessageType": [
"urn:message:Masstransit.MultipleBus.ServiceBus.Models.Commands:Proposta"
]
}
消费者创业公司：
services.AddMasstransit<IAzureServiceBusService>(x =>
{
x.AddConsumer<EnviarExemploPocAzureServiceBusCommandHandler>();
x.UsingAzureServiceBus((context,cfg) =>
{
cfg.UseConcurrencyLimit(serviceBusSettings.AzureServiceBusSettings.ExemploAplicacaoPocA.ConcurrencyLimit);
cfg.Host("connString",h =>
{
h.OperationTimeout = TimeSpan.FromSeconds(serviceBusSettings.AzureServiceBusSettings.ExemploAplicacaoPocA.OperationTimeout);
h.TransportType = Microsoft.Azure.ServiceBus.TransportType.AmqpWebSockets;
});
cfg.UseServiceBusMessageScheduler();
});
});
services.AddMasstransitHostedService();
services.AddSettings(configuration);
处理程序：
namespace Masstransit.MultipleBus.ServiceBus.Handlers.CommandHandlers
{
public class EnviarExemploPocAzureServiceBusCommandHandler : IConsumer<Proposta>
{
public async Task Consume(ConsumeContext<Proposta> context)
{
await Task.CompletedTask;
}
}
public class EnviarExemploPocAzureServiceBusFaultCommandHandler : IConsumer<Fault<EnviarExemploPocAzureServiceBusCommand>>
{
public async Task Consume(ConsumeContext<Fault<EnviarExemploPocAzureServiceBusCommand>> context)
{
await Task.CompletedTask;
}
}
}
当我也使用Masstransit发送消息时，使用者工作并且消息排队如下：
{
"messageId": "00010000-0faa-0009-6497-08d854edbfe1","conversationId": "00010000-0faa-0009-3b83-08d854edbfe5","sourceAddress": "sb://organization.servicebus.windows.net/XXXX","destinationAddress": "sb://organization.servicebus.windows.net/topic","messageType": [
"urn:message:Masstransit.MultipleBus.ServiceBus.Models.Commands:Proposta"
],"message": {
"nome": "TESTE DOIS","mensagem": "TESTE DOIS"
},"sentTime": "2020-09-09T18:25:37.6127127Z","headers": {
"MT-Activity-Id": "|1e87ff49-4beb56732bfd4887.3."
},"host": {
"machineName": "NOTEXXXXXX","processName": "iisexpress","processId": 37092,"assembly": "Masstransit.MultipleBus","assemblyVersion": "1.0.0.0","frameworkVersion": "3.1.5","masstransitVersion": "7.0.2.0","operatingSystemVersion": "Microsoft Windows NT 10.0.19041.0"
}
}
我在做什么错？ 名称空间似乎是正确的，我做了关于它的所有事情，但我无法使其正常工作。 有人可以帮我吗？
