    python b站视频下载的五种版本

    项目地址:

    https://github.com/Henryhaohao/Bilibili_video_download

    介绍

    1.下载全集:直接传入B站av号或者视频链接地址(eg: 49842011或者https://www.bilibili.com/video/av49842011)
    2.下载其中一集:传入那一集的视频链接地址(eg: https://www.bilibili.com/video/av19516333/?p=2)

    版本一: bilibili_video_download_v1.py

    加密API版,不需要加入cookie,直接即可下载1080p视频

    版本二:bilibili_video_download_v2.py

    1.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
    2.如果想下载1080p+视频,需要带入B站大会员的cookie中的SESSDATA才行,普通用户的SESSDATA最多只能下载1080p视频;请定期更换代码31行cookie中的SESSDATA值。跟换方法为:浏览器登录B站,在开发者模式(按F12) --> application --> cookie中找到SESSDATA值替换即可,一个月的有效期

    项目: B站视频下载
    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=44743619cid=78328965qn=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!!

    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=44743619cid=78328965qn=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!!
