三、使用async_playwright进行异步编程 Playwright 提供了异步 API,使我们能够在 Python 中进行异步编程。下面是一个简单的示例,演示了如何使用async_playwright异步地打开网页并进行基本操作。 import asyncio from playwright.async_api import async_playwright async def main(): # 启动 Playwright async with async_pl...
创建sync_playwright和async_playwright实例 使用sync_playwright创建实例: withsync_playwright()asp:browser=p.chromium.launch()page=browser.new_page() 1. 2. 3. 使用async_playwright创建实例: asyncwithasync_playwright()asp:browser=awaitp.chromium.launch()page=awaitbrowser.new_page() 1. 2. 3. 使用实...
async def get_offers(self): async with async_playwright() as playwright: chromium = playwright.chromium browser = await chromium.launch(executable_path=f"{self.file}/chrome-win/chrome.exe",headless=True) context = await browser.new_context() page = await browser.new_page() async with page....
Playwright使用异步方法的正确姿势 如下代码会正常运行,通过await可以保证脚本的运行顺序 async def playwright_async_demo(): async with async_playwright() as p: browser = await p.chromium.launch(channel="chrome") page = await browser.new_page() await page.goto("http://www.baidu.com") asyncio.run...

1. Python Playwright 概念 Playwright 是一个由 Microsoft 开发的开源自动化框架,支持多个浏览器(包括 Chromium、Firefox 和 WebKit)。它不仅可以用于自动化测试,还可以用于数据抓取、网站监控等任务。Playwright 提供了丰富的 API,使得开发者可以方便地编写自动化脚本。 2. 异步(Async)在 Python 中的含义和用途 在Py...
Context: Playwright Version: Version 1.11.0-1620331022000 Operating System: Windows Python Version: 3.8.10, repro on 3.9.X as well, but can also get it working on a certain conda environment, but a cloned version of that environment does...
