之前分享页面不给展示数据了，我今天发现又可以用了，然而之前的signature值生成已经不适用于新版的sign。
本文简述生成方法，文末提供生成代码。方案仅以学习为目的，禁止滥用。
2021/8/17 今天发现分享页被新版的网页版取代了，不过接口还可以使用。
新版网页版的sign《网页版_signature》
@TOC
页面链接：鞠婧祎分享页面
通过控制台可以清晰的看到两条数据请求，分别是用户信息和用户视频。
用户信息还是和之前一样没有更新，用户视频的signature值变短了。
加密追踪
直接ctrl+F，搜索signature
找到 signature = (0,_bytedAcrawler.sign)(nonce); 并打上断点
刷新页面进行调试，可以发现 nonce是页面上的uid，4199772083203972。
_bytedAcrawler.sign 是 匿名函数中的sign方法。
组合起来就可以生成sign。
当然没这么简单，你需要往下还原方法。
生成思路
还原js，定义自启动方法，定义属性调用sign。
!function anonymous(){...}()(...)
Object.defineProperty(test, "__esModule", {
value: true
});
var signature = (0 , test.sign)(nonce);完整代码
使用时把两个文件放在同一目录下，运行python文件即可。
我把 js 和 python 代码分开了，没有写在一个里面，因为 js的字符串有混淆，windwos系统可能因为字符格式报错。
