问题描述
对不起，如果我的问题很愚蠢，我是MassTransit的新手.
Sorry if my question is dumb, I'm new to MassTransit.
我的系统由一台服务器和多个客户端设备组成.我想从服务器向特定客户端或一组客户端发送消息.据我了解， IBusControl.Publish 将消息发送给所有订阅者，而 IBusControl.Send 发送给唯一的订阅者.
My system consists of a server and multiple client devices.I'd like to send a message from the server to a specific client or to a group of clients.As far as I understand, IBusControl.Publish sends the message to all subscribers, and IBusControl.Send to the only one subscriber.
如何使用MassTransit实现此目的?我的交通工具是RabbitMQ/Azure服务总线.
How can I achieve this using MassTransit?My transports are RabbitMQ / Azure Service Bus.
谢谢！
推荐答案
MassTransit实现标准的消息传递模式，该模式不是MassTransit特定的.点对点，发布-订阅，无效的消息通道，死信通道等:
MassTransit implements standard messaging patterns, which aren't MassTransit-specific. Point-to-point, publish-subscribe, invalid message channel, dead letter channel and so on:
您确实可以选择使用 Send 向一个使用者发送消息，以及使用 Publish 将消息广播给该消息类型的所有订阅者.
You indeed have the choice between sending a message to one consumer using Send and to broadcast messages to all subscribers for that message type by using Publish.
通过向消费者添加代码，可以轻松完成所有其他事情:
Everything else can be easily done by adding code to consumers:
await bus.Publish(new MyMessage { ReceiverGroup = "group1", ... });
和
public async Task Consume(IContext<MyMessage> context)
{
if (context.Message.ReceiverGroup != myGroup) return;
...
}
