原文链接地址：「docker实战篇」python的docker- 抖音视频抓取（中）（25）
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。
