Python下载某课旺M3U8加密文件并合成视频自动创建文件夹
本帖最后由 Teachers 于 2021-9-7 18:21 编辑### 前言
只能手机上下载，我想下载到电脑上，于是就用Python写了这个工具，废话不多说上代码，需要用的身份验证内容得去app上抓。
如果违规请管理员直接删帖！
### 代码

download(value['video_url'], '某课旺视频下载/' + index_make + '/' + str(i + 1) + '-' + o['title'] + '/',
str(item + 1) + '-' + value[
'title'])
dw_url(response.json())
```
目录清晰！
上次搞一个阿里加密的视频课程，吐血了，后面干脆放弃了 非常有希望的下载!! 支持支持 支持 ！！ 热心回复！ 可以可以，支持！ 不错不错！！！ 大神呀，谢谢 好厉害 学习了
