使用python的pika链接rabbitMq断裂

比如我们执行一个很长的任务的时候，执行结束ack确认发现确认失败，mq都断了。

只要是使用pyhon的pika都会出现这个问题，因为pika本身是没有主动发送心跳机制的（你用java的话是没问题的）

解决方式:

在链接中heartbeat=0

credentials = pika.PlainCredentials('xxx','xxx') connection = pika.BlockingConnection(pika.ConnectionParameters( host = "xxxx",port = 5672, credentials = credentials , heartbeat=0 ))

解决方式2:

我亲自试过，确实有用

长时间的话，家里的网抖动可能出现，我们家有时候就会断网个10几秒，有时候打游戏就会掉线：

pika.exceptions.AMQPHeartbeatTimeout: No activity or too many missed heartbeats in the last xx seconds 这种情况，把他拉起就行了，加一个

while True: try: # 用户名密码，没有设置的可以省略这一步 credentials = pika.PlainCredentials('xx', 'xx') connection = pika.BlockingConnection(pika.ConnectionParameters( host="xxxx", port=5672, credentials=credentials, heartbeat=10 )) channel = connection.channel() channel.queue_declare(queue="xxx", durable=True) # 如果是持久化队列就是True channel.basic_qos(prefetch_count=1) channel.basic_consume("xxx", on_message) print(f'main thread id: {threading.get_ident()}') print("开始消费") channel.start_consuming() except KeyboardInterrupt: # channel.stop_consuming() print("出现异常，可能是网络原因，重新启动"+e) time.sleep(30)
