windown 使用python 自动切换网络

由于工作环境的特殊性，有时需要切换到内网工作，有时需要通过手机连接外网，想自动运行一个脚本就做完这事

首先在PC机上安装一个无线网卡，例如360wifi就可以。

除了python，还用到了DOS命令，事实我觉得可以直接通过python来实现，有时间再试试。

以下是实现代码：

import os
import time
import sys
import socket
import subprocess

NET_WLAN_NAME = "WLAN"
NET_LOCAL_NAME = "本地连接"

def operate_network_adapter(adaptername, toopen):
    processx = None
    try:
        cmd = "netsh interface set interface \"%s\" admin=%s" %(adaptername, "disabled" if toopen==False else "enabled")
        processx = subprocess.Popen(cmd, stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.STDOUT, shell=False, creationflags=0x08000000)

        processx.wait()
        if processx.returncode == 0:
            print('\n cmd \"%s\" success.\n' %cmd)
        else:
            print('\n cmd \"%s\" error.\n' %cmd)
        processx.kill()

        pass
    except:
        print('\n%s\n' %(sys.exc_info()[1]))
        pass
    finally:
        if processx != None:
            processx.kill()
        pass
    pass

if __name__ == "__main__":
    process = None

    try:
        myname = socket.getfqdn(socket.gethostname())
        myaddr = socket.gethostbyname(myname)

        if '127.0.0.1' not in myaddr:
            #open local network
            operate_network_adapter(NET_WLAN_NAME, False)
            time.sleep(2)
            operate_network_adapter(NET_LOCAL_NAME, True)
        else:
            #open wlan
            operate_network_adapter(NET_LOCAL_NAME, False)
            time.sleep(2)
            operate_network_adapter(NET_WLAN_NAME, True)

        pass
    except:
        print('\n%s\n' %(sys.exc_info()[1]))
        pass
    finally:
        pass
