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 sleep
from playwright import sync_playwright
with 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 asyncio
from playwright import async_playwright
async 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.<b style="color:transparent">本文来源gao@!dai!ma.com搞$$代^@码网*</b>fixture(scope="session")
def test_playwright_is_visible_on_google(page):
page.goto("https://www.google.com")
page.type("input[name=q]", "Playwright GitHub")
page.click("input[type=submit]")
page.waitForSelector("text=microsoft/Playwright")
执行 JS 代码
from playwright import sync_playwright
with sync_playwright() as p:
browser = p.firefox.launch()
page = browser.newPage()
page.goto('https://www.example.com/')
dimensions = page.evaluate('''() => {
return {
width: document.documentElement.clientWidth,
height: document.documentElement.clientHeight,
deviceScaleFactor: window.devicePixelRatio
} }''')
print(dimensions)
browser.close()
中断网络请求
from playwright import sync_playwright with sync_playwright() as p: browser = p.chromium.launch() page = browser.newPage() def log_and_continue_request(route, request): print(request.url) route.continue_()
记录并继续所有网络请求
page.route('**', lambda route, request: log_and_continue_request(route, request))
page.goto('http://todomvc.com')
browser.close()
