利用土办法+AI编写的视频下载脚本过程复现

pwp

写在最前：年前，学校某位领导参加了一个省级培训，他认为课程很好，想保存下来二天给他下属学习，故而让我把这视频down下来。



时间一晃就过去了大半年，我早已把这事忘得乙肝二静了，前几天他又问我，下好没，我谎称视频太多，才下得几集，并承诺清明下好。于是就准备大肝一次。

逆向了好半天，时间一点一滴地过去了，已经来到凌晨2点多，都模拟不出来，这里我就不赘述这个过程了。

无奈准备放弃，突然零机移动，既然我不能逆向怎么拿到视频地址，我直接复制服务器给的地址下载不就行啦？

直接上我的土办法：

1、既然服务器发送了课程的全部视频给我，还是json格式的：




2、那我不直接问ai写下载脚本就行啦：






3、稍等110秒，就出来脚本了：




4、打工搞成，给大家json和python玩玩：

  采用aiohttp实现异步下载，速度提升5-8倍
• 
  使用连接池限制并发数（建议10-20），避免触发反爬

用正则匹配出下载网址，再用迅雷下载也行。
