MacBookPro 自动化连接网络

背景

因为公司有台MacBookPro笔记本跑一些自动化脚本,但是公司的网络经常会自动断开,平均每两天会自动断开一次,只能手动重新连接网络.

解决目标

主要想通过自动脚本自动连接网络并且形成网络巡检工具.

核心难点是如何通过命令连接网络.

Mac OSX 命令行下控制 Wifi命令

Mac 命令行下查看当前 Wifi网络设备名称

代码语言：javascript复制

networksetup -listallhardwareports

可以看出相关网卡和蓝牙信息.

启动 Wifi

代码语言：javascript复制

networksetup -setairportpower en0 on

关闭 Wifi

代码语言：javascript复制

networksetup -setairportpower en0 off

加入 Wifi

代码语言：javascript复制

networksetup -setairportnetwork en0  WIFI_SSID_I_WANT_TO_JOIN  WIFI_PASSWORD

WIFI_SSID_I_WANT_TO_JOIN是WIFI的名字. WIFI_PASSWORD是WIFI的密码.

执行命令后,WIFI就会自动恢复连接,大概5秒左右.

定时监控脚本

脚本逻辑是: 请求百度共5次并且每次请求间隔2秒,如果出现连接异常,则重新连接网络.

class PingObject():

if __name__ == '__main__':

    scheduler = BlockingScheduler()
    scheduler.add_job(PingObject.job, trigger='interval', minutes=30, id='my_job_id_test', next_run_time=datetime.now())

    scheduler.start()

    print('Press Ctrl {0} to exit'.format('Break' if os.name == 'nt' else 'C'))

    try:
        while True:
            time.sleep(2)  # 其他任务是独立的线程执行
    except (KeyboardInterrupt, SystemExit):
        scheduler.shutdown()
        print('Exit The Job!')

脚本可以放到终端前台或者后台执行即可.

每30分钟自动监控一次,自动报警通知如下.
