Python 通过Playwright+OpenCV破解滑动验证码 实例

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

1. 首先下载 安装 Playwright

pip install playwright

2. 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

3. 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"

4. 主要代码展示
