由于公司最近需要對接某業務系統，涉及到部分數據需要提交至其它平臺業務系統，只有其它平臺賬戶，沒有接口，因此做此開發。首先通過OpenCV計算出驗證驗證碼滑塊距離，根據距離，使用 Playwright 利用滑動距離模擬登錄
下面展示Python 通過 Playwright 滑動及登錄過程
- 首先下載 安裝 Playwright
pip install playwright
- 安裝瀏覽器驅動（此步驟會在本地安裝二進制瀏覽器:火狐、谷歌等）
python -m playwright install
- Playwright 錄制腳本(通過腳本錄制，不需要寫代碼，通過鼠標事件將代碼輸出到文件當中)
python -m playwright codegen -o "D:test.py"
- 主要代碼展示
