读书郎平板定时截图监控平板屏幕内容

现在学生经常需要平板上网课,读书郎家长端有监控平板平板的功能,但是频繁手动操作,也不方便。就用appium实现定时去抓取一下平板使用情况。经过一天的时间,终于实现稳定、定时抓取读书郎平板屏幕截图。里面有一些很实用的知识点

脚本写好后 ,还需要执行一个批处理文件,每隔120秒执行一次脚本

@echo off
for /l %%a in (1, 1, 5000) do (
  echo %%a
    D:workStockprojectreadboyvenvScriptspython.exe D:/work/Stock/project/readboy/readboy_cap.py
    TIMEOUT /T 120
)
'pause

在抓取过程中,还看到有破坏分子进入腾讯会议进行破坏,干扰教学
