计算抖音_signature

获取抖音数据一定要会计算_signature的值.网上的教程一大堆.我看了很多,也试着运行了.发现基本上都是不能用的,或者作者写的非常不清楚.自己研究了半天.写一个可以直接运行的供大家参考

准备工作

  • 找一个分享链接 在抖音,记录美好生活! http://v.douyin.com/5jDQWr/
  • 找到页面上的tac.下面有图示
  • 修改douyin.js 里面我有写注释的地方.替换为刚才找到的tac.
  • 运行代码,得到跟页面上显示的同一个_signature值
  • 异常错误忽略,不影响

run

# 需要安装jsdom   npm i jsdom
#node douyin.js uid
node douyin.js 1604937842691048

tac在哪里

补充说明

现在还有一个获取tac的动作,需要各位自己用后端获取后传过来执行.自己实现,这边就不写了
