一个获取B站视频封面的小工具
本帖最后由 Traitor 于 2022-3-28 14:04 编辑刚入门Python的小菜鸡，用的是面向过程写的，代码有点乱，有什么问题还望指出，代码有点长。
最下面有开源地址和附件
说明：
1.如果视频的分p则直接输出每个视频的封面信息，不是则输出一个视频的封面信息。
2.每集番剧封面也就是带有ep号的表示某一集，电影封面也是带ep号。
3.md链接则是直接获取该番剧的全部封面，一般点击b站番剧下面的番剧标题，就可以进入到该番剧的md链接下了。
链接样式：

https://www.bilibili.com/video/av679711482
注意：
1.还有一种视频是分p但是不能获取全部分p的封面，也算是一个小bug吧
2.如果该番剧是即将上线的情况下，md号只能获取到该番剧的海报图和相关信息，同样ss号不能获取到内容
3.如果输入了错误的信息则返回空
支持： bv号、av号、ep号、ss号、md号、带有bv号链接、av号链接、ep链接、ss号链接、md号链接、手机端分享链接直接粘贴即可
更新：2022年3月28日14:02 修改了输出内容的逻辑让代码看起来不是那么复杂
