项⽬: B站动漫番剧(bangumi)下载
版本2: ⽆加密API版，但是需要加⼊登录后cookie中的SESSDATA字段，才可下载720p及以上视频
API:
源码资本最佳投资人
1.获取cid的api为 api.bilibili/x/web-interface/view?aid=47476691 aid后⾯为av号
2.下载链接api为 api.bilibili/x/player/playurl?avid=44743619&cid=78328965&qn=32 cid为上⾯获取到的 avid为输⼊的av号 qn为视频质量
注意:
但是此接⼝headers需要加上登录后'Cookie': 'SESSDATA=3c5d20cf%2C1556704080%2C7dcd8c41' (30天的有效期)(因为现在只有登录后才能看到720P以上视频了)不然下载之后都是最低清晰度，哪怕选择了80也是只有480p的分辨率!!
