ConnectionResetError: [Errno 104] Connection reset by peer|4-16

python socket 编程，sftp远程读日志文件，取最后的30行返回。收到ConnectionResetError: [Errno 104] Connection reset by peer报错。

最后找到原因是send的数据size太大，服务器端重置了连接

Traceback (most recent call last):

 File "s1.py", line 63, in <module>

   data = tcpCliSock.recv(bufsize).decode()

ConnectionResetError: [Errno 104] Connection  reset by peer

解决办法：把异常by pass

from  socket import error as SocketError

import errno

try:

    ...

    ...

except SocketError as e:

   if e.errno != errno.ECONNRESET:

       raise

   pass
