用python监控电脑的电量，小于设定值后，并通过飞书机器人通知

1. 使用pip3安装pustil

   pip3 install pustil

2. 每隔10分钟检查电脑电量和充电状态

   def check_power_electric():
   
       while True:
           time.sleep(600)  # 每隔10分钟检查一次
           battery = psutil.sensors_battery()
           plugged = battery.power_plugged
           percent = str(battery.percent)
           if plugged == False:
               # 未接入电源线，没有在充电
               plugged = "Not Plugged In"
           else:
               plugged = "Plugged In"
           if int(percent) <= 40 and plugged == "Not Plugged In":
               print(recent)

3. 使用飞书机器人发送通知

   def send_notify(percent):
       webhook = "替换你的飞书机器人webhook地址"
       headers = {
           "Content-Type": "application/json",
           "Charset": "UTF-8"
       }
       message = {
           "msg_type": "post",
           "content": {
               "post": {
                   "zh_cn": {
                       "title": "测试服务器电量剩余{0}%，请及时充电!!!".format(percent),
                       "content": [
                           [
                               {
                                   "tag": "text",
                                   "text": ""
                               },
                           ]
                       ]
                   }
               }
           }
       }
       requests.post(url=webhook, json=message, headers=headers)

4. 当电量低于40%时且不在充电时，发送通知。修改第2步的代码

    if int(percent) <= 40 and plugged == "Not Plugged In":
          send_notify(percent)

5. 启动监控进程

   if __name__ == '__main__':
       t = Thread(target=check_power_electric)
       t.start()

6. 完整代码如下：

   import psutil
   import time
   import requests
   from threading import Thread
   
   def check_power_electric():
   
       while True:
           time.sleep(600)  # 每隔10分钟检查一次
           battery = psutil.sensors_battery()
           plugged = battery.power_plugged
           percent = str(battery.percent)
           if plugged == False:
               # 未接入电源线
               plugged = "Not Plugged In"
           else:
               plugged = "Plugged In"
           if int(percent) <= 40 and plugged == "Not Plugged In":
               send_notify(percent)
   
   def send_notify(percent):
       webhook = "替换你的飞书机器人webhook地址"
       headers = {
           "Content-Type": "application/json",
           "Charset": "UTF-8"
       }
       message = {
           "msg_type": "post",
           "content": {
               "post": {
                   "zh_cn": {
                       "title": "测试服务器电量剩余{0}%，请及时充电!!!".format(percent),
                       "content": [
                           [
                               {
                                   "tag": "text",
                                   "text": ""
                               },
                           ]
                       ]
                   }
               }
           }
       }
       requests.post(url=webhook, json=message, headers=headers)
   
   
   if __name__ == '__main__':
       t = Thread(target=check_power_electric)
       t.start()

7. 使用nohup和&启动

   #在iterm窗口执行（在check_power.py文件同一目录下执行）
   #启动
   nohup python3 check_power.py &
   
   #查看是否成功
   ps -ef|grep check_power.py
   
   #kill进程，退出监控
   kill -9 PID
   

   　　

　　 至此结束，希望对你有点帮助
