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:
1.获取cid的api为 https://api.bilibili.com/x/web-interface/view?aid=47476691 aid后面为av号
2.下载链接api为 https://api.bilibili.com/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!!
