B站最新視訊下載下傳連結的擷取

之前直接用的工具，發現21年的視訊不能下載下傳，得，還得自己分析一下

本文隻講方法，不提供工具，僅供學術研究~

1.擷取視訊的AID和CID

B站AID和CID的擷取的本質（直接搜CID更友善）

偷懶工具：

2.解析視訊

替換AID和CID：

https://api.bilibili.com/x/player/playurl?avid={1}&cid={2}&qn=1&type=&otype=json&platform=html5&high_quality=1

通過浏覽器拿到傳回值：

{"code":0,"message":"0","ttl":1,"data":{"from":"local","result":"suee","message":"","quality":192,"format":"mp4720","timelength":3045000,"accept_format":"mp4720","accept_description":["高清 720P"],"accept_quality":[192],"video_codecid":7,"seek_param":"start","seek_type":"offset","durl":[{"order":1,"length":3045000,"size":716993619,"ahead":"","vhead":"","url":"https://upos-sz-mirrorcos.bilivideo.com/upgcxcode/02/15/315891502/315891502-1-192.mp4?e=ig8euxZM2rNcNbNz7WdVhwdlhbhBhwdVhoNvNC8BqJIzNbfq9rVEuxTEnE8L5F6VnEsSTx0vkX8fqJeYTj_lta53NCM=\u0026uipk=5\u0026nbs=1\u0026deadline=1642306699\u0026gen=playurlv2\u0026os=cosbv\u0026oi=3748392193\u0026trid=6b16b2feeedb48d5b448d8373e20367bT\u0026platform=html5\u0026upsig=bf7ce69d2e89bcbda89406bb8bd26fc1\u0026uparams=e,uipk,nbs,deadline,gen,os,oi,trid,platform\u0026mid=0\u0026bvc=vod\u0026nettype=0\u0026bw=235465\u0026orderid=0,1\u0026logo=80000000","backup_url":null}],"support_formats":[{"quality":192,"format":"mp4720","new_description":"720P 高清","display_desc":"720P","superscript":""}],"high_format":null}}
           

3.通路下載下傳

隻需要url裡面的值，然後把轉義字元

\u0026

還原成

打開就可以下載下傳視訊了：

4.測試

随便點個2022的視訊也是可以的：
