山东大学断网自动重连

需要用到山东大学校园网，实现断网自动重连。

代码实现如下：

 coding=utf-8

import requests
import time
import os
import subprocess
import re

class Reconnect:
    # 初始化
    def __init__(self):
        # 检测间隔时间，单位为秒
        self.every = 10


    # 获取当前时间戳，13位
    def getNowTime(self):
        return str(int(time.time())) + "000"
    # 获取ip
    def get_ipconfig_ip(self):

        ipconfig_result_list = os.popen('ipconfig').readlines()  # 执行cmd命令ipconfig，并将结果存于ipconfig_result_list

        for i in range(0, len(ipconfig_result_list)):  # 逐行查找
            if re.search(r'无线局域网适配器 WLAN', ipconfig_result_list[i]) != None:

                for j in range(1, 8):
                    if re.search(r"IPv4 地址", ipconfig_result_list[i + j]) != None:
                        match_ip = re.search(r'\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}', ipconfig_result_list[i + j]).group(
                            0)  # 由正则表达式获取ip地址
                        return match_ip

        return None
