抖音分享页面
之前有相关文章介绍了分享页面的抓取和sign值的生成。要看详细方法可点击下方链接。
本篇文章主要是说一下最新生成sign值的代码，最后会贴在文章下方。
新版的分享页面上增加了webdriver的验证，并且今年谷歌新版本浏览器停止了对开发者模式隐藏webdervier的支持。
导致了之前的 add_experimental_option(‘excludeSwitches’, [‘enable-automation’])失效了。方法在下面文章
抖音视频sign值生成
页面链接： https://www.amemv.com/share/user/102064772608
102064772608就是分享页面需要的ID。
页面上的数据：
下面是我提取出的数据 :
运行环境：
| Package | Version |
|---|---|
| python | 3.6.8 |
| Google Chrome | 80.0.3987.163 |
| Selenium | 3.141.0 |
需要安装selenium和对应的谷歌驱动。

抖音无水印视频
当前保存的 videoUrl 链接是经过处理后的，如果需要无水印的视频。
把 videoUrl 链接中的 playwm 替换成 play 。删除 watermark=1 。
然后把浏览器切换为手机版，再打开链接。
使用程序下载的时候需要使用手机版的 User-Agent。
