纠正在RabbitMQ中导致交换失败的内容

Question

As per the tutorial, I use var consumer = new EventingBasicConsumer(channel); to register message on the queue.

But I noticed that if the exchange is deleted, (forcefully using the API), or by stopping rabbit, I don't actually get any notification that something is wrong

var consumer = new EventingBasicConsumer(channel);
consumer.Received += (model, ea) =>
{
    var body = ea.Body;
    var message = Encoding.UTF8.GetString(body);
    Console.WriteLine(" [x] Received {0}", message);
};

What events can I register to tell if/when the exchange was deleted or if I was somehow disconnected for whatever reason?

Answer 1

There is nothing wrong if an exchange is deleted. Since your consumer consumes from a queue , the only result is that no more messages are routed from this exchange to the queue.

This is different from your consumer being disconnected from the queue or the queue being deleted which will result in your consumer being disconnected. Check out HandleModelShutdown and other methods your consumer can implement for such cases.
