RabbitMQ RPC 如何自动删除回调队列

Question

I would like to know how to delete the callback queue after the client receive the callback message. After multiples RPC calls I have a lot of callback queues I'm not using any more.

I declare the callback queue as following:

replyToQueueName = _channelListener.QueueDeclare(durable: false,
exclusive: false, autoDelete: true, arguments: null).QueueName;

I thought they were going to be deleted after use but this is not the case. I can see with the management plugin the queues still have a consumer.

Maybe I just must delete the queue after receive the callback message, but I'm not sure is the best approach: channel.QueueDelete("queue-name", false, false);

I've been using this tutorial

Answer 1

I have found a solution (not sure if is the best solution). After receive the callback message, I unsubscribe the consumer:

channel.BasicCancel(consumer.ConsumerTags[0]);

This way the callback queue has no consumer, and it's deleted immediately.
