Pub/Sub: how to simulate rabbitmq routing_key

[Kiran]

Currently we use RabbitMQ for Pub/Sub. We have a standard message defined which carries the payload and is published on an exchange with a routing key. Subscribers then subscribe with a specific routing key. This way subscribers only consumer messages which they are interested in (based on routing key). 

In Masstransit world how can I implement this functionality. We currently use Request/Response and Send (which is tied to a specific queue).

Thanks

Routing key support is coming but not currently built into MassTransit.

Thanks much.

I assume I can use the custom biding in consumer.  How do I add Routing Key when publishing?

Use sendContext.GetPayload<RabbitMqSendContext>().RoutingKey = "....";

Thanks much. One more question, how can I set the routing key in Request/Response. Also when using Masstransit.Host is there a way to set the routing Key.

### For request

 busControl = Bus.Factory.CreateUsingRabbitMq(x =>

            {

                var host = x.Host(new UriBuilder("rabbitmq", _hostName).Uri, h =>

                {

                    h.Username(*****);

                    h.Password(*****); 

                });

            });

busControl.Start();

 busControl.CreateRequestClient<TRequest, TResponse>(new Uri("rabbitmq://" + _hostName + "/" + queueName), timeout.Value);

Not really. The next version with topology makes this a lot easier to work out via conventions. I really need to finish it as it's still under development. 

The develop branch has all the code I just need to test it more.
