太长了，就不放出所有了，video中的backUrl是视频下载地址（记得加ua和referer）对应的id编号
116：1080，60
80：1080
64：720
。。。一一对应的
怎么提取？：
方法1.
万能的正则表达式（只要条件够多，没有匹配不出来的）
方法2.
把前缀去掉，用json.loads()转化为json字典，再用字典的key，value提取
视频下一集
我在F12界面中没看到，但在页面源代码中看到了
直接用python提取

查看下一个视频就知道使用p来切换的
把page获取，name获取就行了
番剧下载地址
下载地址提取方式差不多，拿罪恶王冠.举例，用代码提取
window.__playinfo是下载地址，
window__initial是下一集地址，提取方式差不多，但要记住要提取哪类链接（最好是ep的）
其他项用if过滤就行了。
这些就是下载b站视频的大致操作了。比iqiyi那些简单多了
