### 使用 Playwright 在 Jupyter Notebook 中进行自动化浏览器操作为了在 Jupyter Notebook 环境中使用 Playwright 进行网页自动化测试或数据抓取工作，需要先安装必要的 Python 包。可以通过 pip 安装最新版本的 `playwright` 和其依赖项[^1]。 ```bash pip install playwright ``` 接着，在首次运行之前还需要下载所需的浏览器二进制文件： ```python import asyncio from playwright.async_api import async_playwright async def setup_browsers(): pw = await async_playwright().start() await pw.chromium.launch() # 或者 firefox, webkit await pw.stop() await setup_browsers() ``` 创建一个新的单元格来编写具体的脚本逻辑。下面是一个简单的例子，展示如何打开页面并截屏保存： ```python import asyncio from IPython.display import display, Image from playwright.async_api import async_playwright async def capture_screenshot(url='https://example.com', path='screenshot.png'): async with async_playwright() as p: browser = await p.chromium.launch(headless=False) page = await browser.new_page() await page.goto(url) await page.screenshot(path=path) await browser.close() display(Image(filename=path)) await capture_screenshot() ``` 这段代码会启动 Chromium 浏览器实例（非无头模式），导航到指定 URL 并捕获整个视口的截图，最后关闭浏览器连接并将图片显示出来[^2]。
