python代码示例 playwright异步批量打开网页

以下是一个使用playwright异步批量打开网页的Python代码示例：

import asyncio
from playwright.async_api import Playwright, async_playwright


async def open_page(browser_type: str, url: str):
    async with async_playwright() as p:
        browser: Playwright = await getattr(p, browser_type).launch()
        page = await browser.new_page()
        await page.goto(url)
        await asyncio.sleep(3)
        content = await page.content()
        print(content)
        await browser.close()


async def main():
    urls = [
        "https://www.google.com",
        "https://www.bing.com",
        "https://www.baidu.com",
        "https://www.yahoo.com",
    ]
    browser_types = ["chromium", "firefox", "webkit"]

    tasks = []
    for browser_type in browser_types:
        for url in urls:
            tasks.append(open_page(browser_type, url))

    await asyncio.gather(*tasks)


if __name__ == "__main__":
    asyncio.run(main())
