kombu未重新连接到RabbitMQ

Question

我有两台服务器，分别叫做A和B。B运行RabbitMQ，而A通过Kombu连接到RabbitMQ。如果我在B上重新启动RabbitMQ，则kombu连接断开，消息不再传递。然后，我必须重置A上的进程以重新建立连接。有没有更好的方法，也就是说，有没有一种方法可以让Kombu自动重新连接，即使RabbitMQ进程重新启动了？

我的基本代码实现如下，提前感谢！:)

def start_consumer(routing_key, incoming_exchange_name, outgoing_exchange_name):
    global rabbitmq_producer

    incoming_exchange = kombu.Exchange(name=incoming_exchange_name, type='direct')
    incoming_queue = kombu.Queue(name=routing_key+'_'+incoming_exchange_name, exchange=incoming_exchange, routing_key=routing_key)#, auto_delete=True)

    outgoing_exchange = kombu.Exchange(name=outgoing_exchange_name, type='direct')
    rabbitmq_producer = kombu.Producer(settings.rabbitmq_connection0, exchange=outgoing_exchange, serializer='json', compression=None, auto_declare=True)

    settings.rabbitmq_connection0.connect()
    if settings.rabbitmq_connection0.connected:
        callbacks=[]
        queues=[]

        callbacks.append(callback)
        # if push_queue:
        #   callbacks.append(push_message_callback)
        queues.append(incoming_queue)

        print 'opening a new *incoming* rabbitmq connection to the %s exchange for the %s queue' % (incoming_exchange.name, incoming_queue.name)
        incoming_exchange(settings.rabbitmq_connection0).declare()
        incoming_queue(settings.rabbitmq_connection0).declare()

        print 'opening a new *outgoing* rabbitmq connection to the %s exchange' % outgoing_exchange.name
        outgoing_exchange(settings.rabbitmq_connection0).declare()

        with settings.rabbitmq_connection0.Consumer(queues=queues, callbacks=callbacks) as consumer:
            while True:
                settings.rabbitmq_connection0.drain_events()

在消费者端，当连接断开时，kombu.mixins.ConsumerMixin处理重新连接(还处理心跳等，并允许您编写更少的代码)。不幸的是，似乎没有ProducerMixin，但您可以深入研究代码并对其进行调整...？
