由于公司最近需要对接某业务系统，涉及到部分数据需要提交至其它平台业务系统，只有其它平台账户，没有接口，因此做此开发。首先通过OpenCV计算出验证验证码滑块距离，根据距离，使用 Playwright 利用滑动距离模拟登录
下面展示Python 通过 Playwright 滑动及登录过程
- 首先下载 安装 Playwright
pip install playwright
- 安装浏览器驱动（此步骤会在本地安装二进制浏览器:火狐、谷歌等）
python -m playwright install
- Playwright 录制脚本(通过脚本录制，不需要写代码，通过鼠标事件将代码输出到文件当中)
python -m playwright codegen -o "D:test.py"
- 主要代码展示
