開源方：微軟

安裝：pip install playwright；python -m playwright install

特點：自動化腳本錄制；有同步、異步api

生成代碼指令：python -m playwright codegen其他：需要Python 3.7及以上；官方api為node版本，python版本待補充

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) # 默認無頭，這樣為有頭模式 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=百度熱榜') page.screenshot(path=f’example-{browser_type.name}.png’) sleep(5) browser.close()異步：關鍵字為：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=百度熱榜') await page.screenshot(path=f’example-{browser_type.name}.png’) await browser.close()asyncio.get_event_loop().run_until_complete(main())集成 pytest 測試

@pytest.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')執行 JS 代碼

from playwright import sync_playwrightwith 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()中斷網絡請求

from playwright import sync_playwrightwith sync_playwright() as p: browser = p.chromium.launch() page = browser.newPage()def log_and_continue_request(route, request): print(request.url) route.continue_()記錄并繼續所有網絡請求

page.route(’**’, lambda route, request: log_and_continue_request(route, request))page.goto(’http://todomvc.com’)browser.close()
