本次主要针对python对上次抖音分享的页面中的_signature进行解析并完成抖音视频的下载。源码https://github.com/limingios/dockerpython.git 源码/「「docker实战篇」python的docker- 抖音视频抓取下24
https://github.com/limingios/dockerpython.git 谷歌插件
找到方法完成本地的html的生成
其实就是复制出来分享页面的函数然后通过函数调用的方式完成_signature的生成。

最终结果
里面关于chromedriver的配置直接引入他的路径最稳了我比较喜欢这种方式网上很多搞环境变量的导致电脑很慢不建议。
PS基本上抖音视频下载的都已经完成了下次对于需要注意的做下总结。
