Python中playwright启动浏览器与常见运行方式详解

from playwright.sync_api import sync_playwright


with sync_playwright() as p:
    browser = p.chromium.launch(headless=False)          # 启动 chromium 浏览器
    page = browser.new_page()              # 打开一个标签页
    page.goto("https://www.baidu.com")     # 打开百度地址
    print(page.title())                    # 打印当前页面title
    browser.close()                        # 关闭浏览器对象
