求助抓B站视频接口
本帖最后由 魔道书生 于 2020-6-29 09:50 编辑最近论坛好多大佬都在发B站视频下载
自己心里也痒痒
参考了@xccxvb 的帖子https://www.52pojie.cn/thread-1203086-1-1.html
看了他的源码
api_url = 'https://api.bilibili.com/x/player/playurl?cid={}&avid={}&qn={}&otype=json&requestFrom=bilibili-helper'api_url = 'https://api.bilibili.com/x/player/playurl?cid={}&avid={}&qn={}&otype=json&requestFrom=bilibili-helper'
想知道这个api是怎么抓到的
我抓了N遍也没找到？？？
我看直链就是类似
http://cn-jstz-dx-v-01.bilivideo.com/upgcxcode/84/90/206729084/206729084-1-16.mp4?expires=1593402542&platform=pc&ssig=tBBeKFj80KZeeCWi5tnmZA&oi=1779007583&trid=13176c3336bf47b5ab22d89eb2daa3aeu&nfc=1&nfb=maPYqpoel5MI3qOUX6YpRA==&cdnid=4965&mid=0&orderid=0,3&logo=80000000
这样的 直接打开返回453 但是却能下载？？？？？？？？
并没有看到有关视频url的接口
每个XHR我都看了 看不到返回视频URL的
求大佬指点
我这里有一份之前帮同事做的下载工具，不过不是通过包抓取的，直接是页面分析（BTW，其实我自己懒得去看，直接在网上找的别人的，感谢已经被我忘记的大佬）
代码如下（ffmpeg这个工具网上下载就好）

from lxml import etree

res = []
try:

if not line in res:
res.append(line)
line = f.readline().strip()
except:
pass
return res

向大佬学习 有可能是app接口 b站很多接口都是passport开头的二级域名 黑龍 发表于 2020-6-29 10:47

那就不知道了啊 等大佬吧{:1_937:} https://github.com/czp3009/bilibili-api/blob/kotlin/src/main/kotlin/com/hiczp/bilibili/api/player/PlayerAPI.kt
这是app逆向出来的接口吧。。 eWVhaA 发表于 2020-6-29 11:40

也是抓到m4s合并的 eWVhaA 发表于 2020-6-29 11:40

好像不是把大佬上面那个接口直接就是flv不用合并 记一次查找bilibili视频API的经历
在视频放完之后可以看到刷出来的新视频时直接调用API接口的
