Simulate the network timeout (unplug the network cable), and then restore the network state. The program receiving data is interrupted, and then it seems to be blocked or unresponsive?

It looks like the group is blocked, I don't know how to deal with it

Execute ctrl+c to get the stack

What I do is catch the exception, wait a bit and then try to reconnect.

我所做的是捕获异常，稍等片刻，然后尝试重新连接。

我直接捕获了错误，但是貌似没错误，得有一个心跳发送，没有返回才会报错，如果没有发送ping的方法，不会报错，会一直hold,不过我现在已经加上心跳，他活的很好，并且重连也很好
