我有一个使用Pika包(0.9.13)的Python客户端,并从RabbitMQ集群中的一个节点检索数据.群集由放置在两个不同主机(url_1和url_2)中的两个节点组成.如何让我的Python客户端订阅这两个节点？

这是我的代码的主要结构:

import pika
credentials = pika.PlainCredentials(user, password)
connection = pika.BlockingConnection(pika.ConnectionParameters(host=url_1,
                                     credentials=credentials, ssl=ssl, port=port))
channel = connection.channel() 
channel.exchange_declare(exchange=exchange.name, 
                         type=exchange.type, durable=exchange.durable)

result = channel.queue_declare(queue=queue.name, exclusive=queue.exclusive, 
                             durable=queue.durable, auto_delete=queue.autoDelete)
channel.queue_bind(exchange=exchange.name, queue=queue.name, 
                   routing_key=binding_key)
channel.basic_consume(callback,
                  queue=queue.name,
                  no_ack=True)

channel.start_consuming()
