Pyhton3 B站下载指定up主所有视频并归类存放（源码）

B站视频下载器

给大家分享两个python3脚本，第一个脚本输入up主的id就可以下载他/她的全部视频（包括多分p视频）且分类存放；第二个脚本输入av/bv号就可以直接下载指定视频（同样包括多分p视频），这两个脚本都是基于you_get实现的。都是复制了就可以用的，非常方便。
源码都已经上传至github，之后修复bug或有新的功能都会及时更新（非常欢迎star或fork）：https://github.com/Eathoublu/BilibiliUserDownloader
鸣谢知乎以及CSDN的各位大佬提供了av号与bv号互转的算法，这在实现过程中起到了至关重要的作用。源码和使用方法如下：

使用方法

环境：python3
需要安装万能的you_get工具包 pip3 install you_get

bilibili_downloader.py：按照up主来下载视频（适用于多分p视频）

参照main函数中的方法：

1. 实例化Manager类，传入一个prefix（即前缀路径）。
2. 调用Manager的run方法，传入一个用户id（即为希望下载的up主的id）
3. enjoy
   注：该工具附带了断点续传功能，在run方法中加入整形参数kstart即可从指定位置继续传输。e.x.假如一个up主有20个视频，你传到第10个的时候断开了，那么屏幕上会显示10/20，那么接下来重新开始运行脚本时，只需传入kstart=10即可从断开的地方继续传输。

bilibili_downloader4SingleVideo.py：按照av号（或者bv号）来下载单独的视频（同样适用于多分p视频）

这是一个补充的脚本，比第一个稍微实用一点。
main函数中几乎一目了然了，方法如下：

1. 实例化Manager。
2. 调用Manager的run方法，参数vid是av号或者bv号，mode：av号就填‘av’反之亦然，prefix是路径，kstart是断点续传，与第一个工具使用方法一致。
