操作系统： CentOS 6.9_x64
python语言版本： 2.7.13
现有一个tcp客户端程序，需定期从服务器取数据，但由于种种原因（网络不稳定等）需要自动重连。
测试服务器示例代码：
https://github.com/mike-zhang/pyExamples/blob/master/socketRelate/tcpServer1_multithread.py
‘‘‘ tcp client with reconnect E-Mail : Mike_Zhang@live.com ‘‘‘ #! /usr/bin/env python #-*- coding:utf-8 -*- import os,sys,time import socket def doConnect(host,port): sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM) try : sock.connect((host,port)) except : pass return sock def main(): host,port = "127.0.0.1",12345 print host,port sockLocal = doConnect(host,port) while True : try : msg = str(time.time()) sockLocal.send(msg) print "send msg ok : ",msg print "recv data :",sockLocal.recv(1024) except socket.error : print "\r\nsocket error,do reconnect " time.sleep(3) sockLocal = doConnect(host,port) except : print ‘\r\nother error occur ‘ time.sleep(3) time.sleep(1) if __name__ == "__main__" : main()
运行效果：
(py27env) [root@local t1]# python tcpClient1_reconnect.py 127.0.0.1 12345 send msg ok : 1498891374.98 recv data : 1498891374.98 send msg ok : 1498891375.98 recv data : 1498891375.98 send msg ok : 1498891376.98 recv data : socket error,do reconnect send msg ok : 1498891381.99 recv data : 1498891381.99 send msg ok : 1498891382.99 recv data : 1498891382.99
这里只是个简单的示例代码，实现了python的tcp自动重连。
