开源方：微软

安装：pip install playwright；python -m playwright install

特点：自动化脚本录制；有同步、异步api

生成代码指令：python -m playwright codegen
其他：需要Python 3.7及以上；官方api为node版本，python版本待补充

同步：关键字为：sync_playwright

from time import sleepfrom playwright import sync_playwrightwith sync_playwright() as p: for browser_type in [p.chromium, p.firefox, p.webkit]: browser = browser_type.launch(headless=False) # 默认无头，这样为有头模式 page = browser.newPage() page.goto('http://baidu.com') page.fill("input[name=\"wd\"]", "AirPython") with page.expect_navigation(): page.press("input[name=\"wd\"]", "Enter") page.waitForSelector("text=百度热榜") page.screenshot(path=f'example-{browser_type.name}.png') sleep(5) browser.close()

异步：关键字为：async_playwright

import asynciofrom playwright import async_playwrightasync def main(): async with async_playwright() as p: for browser_type in [p.chromium, p.firefox, p.webkit]: browser = await browser_type.launch(headless=False) page = await browser.newPage() await page.goto('http://baidu.com') await page.fill("input[name=\"wd\"]", "AirPython") await page.press("input[name=\"wd\"]", "Enter") await page.waitForSelector("text=百度热榜") await page.screenshot(path=f'example-{browser_type.name}.png') await browser.close()asyncio.get_event_loop().run_until_complete(main())

集成 pytest 测试

@pytest.fixture(scope="session")def test_playwright_is_visible_on_google(page): page.goto("https://')browser.close()
