Public class RegisterCustomerConsumer : IConsumer Here’s the updated RegisterCustomerConsumer object: We’re lucky because the ConsumeContext object of the Consume method has the same function. However we have no access to the bus in the consumer. Here’s an example of publishing an IRegisterCustomer: The IBusControl interface has a Publish method that could do the job. One way of achieving it is publishing the event from the RegisterCustomerConsumer object. Our goal is to publish an event as soon as the command has been taken care of.

We’ll have 4 command windows up and running when starting the demo at the end of this post so it’s good to have an easy means of identifying which window belongs to what.

#MASSTRANSIT CONSUMER GET HEADERS REGISTRATION#

We’ll first make a slight change in the Main method of Program.cs:Ĭonsole.Title = "This is the customer registration command receiver." Ĭonsole.WriteLine("CUSTOMER REGISTRATION COMMAND RECEIVER.") We’ve also registered an IConsumer called RegisterCustomerConsumer when building the bus control. It currently listens to commands on the queue called. We also have a project called MassTransit.Receiver in our demo project. When a new customer is registered then we won’t publish all the details to the consuming parties. It has some of the same properties as IRegisterCustomer. Go ahead and insert the following event interface into the library: Our demo project has a M圜ompany.Messaging C# library where we already have a command-style interface called IRegisterCustomer. We know from the previous post and the MassTransit documentation page we referred to that an event name consists of a noun, which is the resource or the domain, followed by a verb in past tense that describes what happened to the resource. The event will be consumed by 2 receivers that the event publisher will not have any knowledge of. The goal is to publish a customer registered event from the register customer command consumer. In this post we’ll extend our demo to publishing a message that can be consumed by multiple receivers. Our first example centred around sending a single command using a single queue.

Instead, they are basic terminology in the world of messaging. Therefore commands and events are not some special C# language features in this case. Both are best encapsulated in an interface with get-set properties and separate naming conventions. The message type can by convention be an event or a command.

We saw a very basic configuration of the bus control and how to register a consumer for a message type. We managed to send a message from a publisher to a consumer using the MassTransit/RabbitMq client library.

#MASSTRANSIT CONSUMER GET HEADERS CODE#

I’m using Autofac here, but the code is quite similar for other IoC containers.I’m registering the IUserFactory that stores the users data as a scoped instance Now we need to add the necessary registrations.Notice that to get it working I had to use the Service Locator pattern and resolve the IoC instance through the context provided in the send method.First we create a ConsumerConsumeContext filter.What I need is an implementation of a ConsumerConsumeContext filter(quite a mouthful). As I mentioned yesterday I discovered the way to go when having a look at the Masstransit pipeline: Unfortunately these filters doesn’t share the same scope with the consumer and turn out not to be a good solution for my use case. This use case doesn’t sound too hard and a first look at the documentation showed that you can have scoped filters Idea is that the same scope is applicable inside my consumer so that I’m guaranteed that the correct audit information is written into the database. I want a MassTransit filter that reads out some user information from a message header and store it in a scoped class.
