I have just added a number in respect to the Consumer project number. The only difference would be in the value of subscription in the Startup file of the Consumer. Next we need to follow the same process of creating classes, modifying Startup files for the rest of the Consumer projects.
need to always start the bus, so it behaves correctly This is done during bus configuration, particularly within the configuration of a receive endpoint.Ĭonfigurator.SubscriptionEndpoint(subscriptionName, endpointConfigurator =>ĮndpointConfigurator.ConfigureConsumer(registrationContext) Var host = configurator.Host(connectionString) Ĭonfigurator.Message(m => ) įor a consumer to receive messages, the consumer must be connected to a receive endpoint. would normally be in different applications ServiceCollectionConfigurator.AddConsumer() Services.AddMassTransit(serviceCollectionConfigurator => Var subscriptionName = "new-purchase-topic-subscriber" Var newPurchaseTopic = "new-purchase-topic" // need to make sure the topic name is written correctly Var connectionString = "Endpoint=sb:/// SharedAccessKeyName=RootManageSharedAccessKey SharedAccessKey=blablasharedaccesskey" We’re done with Sender for now, so let’s move to one of the Consumer projects.Īdd a new class and call it PurchaseConsumer. To note, because we are using topics we need to use IPublishEndpoint rather than ISendPointProvider like you would do for Queues. specify the message Purchase to be sent to a specific topicīusFactor圜onfig.Message(configTopology =>ĬonfigTopology.SetEntityName(newPurchaseTopic) Ĭonfig.AddBus(provider => azureServiceBus) Var azureServiceBus = (busFactor圜onfig => create the bus using Azure Service bus Var newPurchaseTopic = "new-purchase-topic" "Endpoint=sb:/// SharedAccessKeyName=RootManageSharedAccessKey SharedAccessKey=blablasharedaccesskey" Public void ConfigureServices(IServiceCollection services) Next add the HttpPost method NewPurchase. In the Controller folder of the Sender project add a new controller.
#Masstransit http code
Next thing we would be adding the code to publish and consume message
#Masstransit http install
In that tab search for each of these packages and install them to Sender and Consumer projects. Right click on the project and select Manage Nuget Packages. We need to install several MassTransit related packages in addition to Azure Service bus. Next thing is to add several Nuget packages AsbMassNetCoreTopic.Consumer, AsbMassNetCoreTopic.Consumer1 etc For me it’s easier to track Consumers with name to contain a number e.g. Or you can process it and send it further where you want to.Īdd multiple new web app projects to this solution and select Empty template. In essence this is where our message would end up going. Now we need to add multiple Consumers or Receivers. Net Standard these would be able to share a particular class library without any issues.
Net platform versions(.Net Framework 4.5 and. In other words if you got two projects of different. The reason why we add the class library of Net Standard is because it provides a uniformity in the. You can read a definition for it here or here. In the same solution add New Project and select Class Library (.Net Standard) This project will contain our Contracts. This project is going to be our Sender according to Microsoft resources or Producers according to Masstransit documentation. Open Visual Studio and choose ASP.NET Core Web Application. You can have an Inventory management system that tracks when stock needs to be replenished and Management a Dashboard to view details of their sales. In a real world example this could be different users, different systems and so on.Īs with the Point of sale system example. Each subscriber can receive a copy of the same message. Whereas with Topics the message is available to one or many subscriptions. It is always one message to one consumer though – one to one relationships. The main difference is that the message in the Queue is consumed by one or more competing consumers. Here is a Microsoft example that I have based this tutorial on. The case study would be around the POS(point of sale) system. This is quite similar to a post about Azure Service Bus Queue with MassTransit.
#Masstransit http how to
In this post I will explain how to create a service bus topic, subscribe to it and consume it.
