Playwright 是一个强大而灵活的工具,能够帮助我们高效地进行浏览器自动化操作。通过使用playwright.async_api的异步 API,我们可以编写高性能的异步脚本,完成各种自动化任务。无论是自动化测试还是网页数据抓取,Playwright 都是一个值得学习的利器。 希望本文对你了解 Playwright 和使用async_playwright进行异步浏览器自动化有...
导入sync_playwright和async_playwright 在Python文件中导入sync_playwright和async_playwright: fromplaywright.sync_apiimportsync_playwrightfromplaywright.async_apiimportasync_playwright 1. 2. 创建sync_playwright和async_playwright实例 使用sync_playwright创建实例: withsync_playwright()asp:browser=p.chromium.launch()...
异步代码的编写方法与同步基本一致,区别在于同步调用的是 sync_playwright,异步调用的是 async_playwright。最终运行效果与同步一致。 import asyncio from playwright.async_api import async_playwright async def main(): async with async_playwright() as p: browser = await p.chromium.launch(headless=False) pag...

可以看到整个写法和同步模式基本类似,导入的时候使用的是 async_playwright 方法,而不再是 sync_playwright 方法。写法上添加了 async/await 关键字的使用,最后的运行效果是一样的。 另外我们注意到,这例子中使用了 with as 语句,with 用于上下文对象的管理,它可以返回一个上下文管理器,也就对应一个 PlaywrightContext...
这里我们使用sync_playwright上下文管理器同步启动Playwright,然后编写同步测试逻辑。 Python - 异步模式 使用async_api,我们可以编写异步的测试脚本: fromplaywright.async_apiimportasync_playwright asyncdefrun(playwright):chromium = playwright.chromiumbrowser =awaitchromium.launch()page =awaitbrowser.new_page()await...
