download_youtube_videos(video_urls, cookie_file, output_path, user_agent)

需要注意的几点是

1,yt_dlp库

2,UA模仿正常用户浏览

3,携带Cookie

其中,mission.txt是待下载的视频ID,youtube.com_cookies.txt为登录Youtube后导出的Cookie,格式如下:

# Netscape HTTP Cookie File
# http://curl.haxx.se/rfc/cookie_spec.html
# This is a generated file!  Do not edit.

.youtube.com	TRUE	/	TRUE ......

可以使用此类工具导出:
