python使用pika链接rabbitmq Connection reset by peer 解决办法

记录一下，

最近在用机器学习打算做一个Rest API, 数据存入mongo,任务采用消息队列，rabbitmq

由于引擎采用python编写，所以WEB也直接打算用python编写了，比较省事。

WEB采用flask,连接rabbitmq使用pika，但是在链接过程中，无论是消费还是生产，只要过了一段时间就会主动断链，

提示：

Connection reset by peer

其实原因很简单，服务端没有收到客户端的心跳包，默认是10秒，但是预计的已经超过10秒还没有发心跳包，所以服务端主动断连了。

解决的办法：

py2的代码：

在py3:ConnectionParameters设置heartbeat_interval=0即可。

在py2:ConnectionParameters设置heartbeat=0即可。
