快手用户公开视频下载代码

最近刷快手发现有些想缓存的视频下载不了，于是就用了一两天的时间研究了一下快手，可以通过用户的快手ID（用eid也可以）下载用户所有公开的视频（私有视频需要用户的token，不登录拿不到），可能有些用户没有快手ID，只有用户id，所以在文章后面我会放上一段通过用户id查询用户eid的代码。

# ID: Heniao__
USER_IDS = ['Lijing1997']  # 快手ID列表，也可以用eid列表
SAVE_PATH = 'C:\\Users\\Lay\\Desktop'  # feeds下载存储路径

通过用户id查询用户eid，eid可用于上面的视频下载
