原理：利用[playwright](https://playwright.dev/)搭桥，保留登录成功后的上下文浏览器环境，通过执行JS表达式获取一些加密参数
通过使用此方式，免去了复现核心加密JS代码，逆向难度大大降低。
## 项目特点
- 类型注解，代码结构清晰，方便阅读
- 项目实现有点复杂，但是使用起来比较稳定
- 这种利用浏览器搭桥的方式可以应用到其他平台的爬虫，只需要修改一些参数即可
## 已实现

- [x] 并发执行爬虫请求
- [x] 抖音登录（二维码、手机号、cookies）
- [x] 抖音滑块（模拟滑动实现，准确率不太OK）
- [x] 支持登录成功后的上下文浏览器环境保留
## 待实现
