练习 02: 用 Playwright 持久化浏览器目录保留登录态。
|
|
|
|
目标:
|
|
1. 自己导入 `sync_playwright`
|
|
2. 学会 `launch_persistent_context(user_data_dir=...)`
|
|
3. 打开一个固定页面后，手动确认这个浏览器目录会被复用
|
|
4. 理解为什么不要直接复用你日常 Chrome 默认资料目录
|
|
|
|
建议:
|
|
- 第一版先把浏览器正常启动起来
|
|
- `user_data_dir` 建议放在项目目录里，便于观察
|
|
- 如果你想验证登录态，连续运行两次并观察 cookie / 登录状态变化
|
|
|
|
运行:
|
|
./.venv/bin/python learning/playwright_basics/02_persistent_context.py
