開源方：微軟

安裝：pip install playwright；python -m playwright install

特點：自動化指令碼錄製；有同步、非同步api

生成程式碼指令：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

同步：關鍵字為：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) # 預設無頭，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()

非同步：關鍵字為：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=百度熱榜")
            await page.screenshot(path=f'example-{browser_type.name}.png')
            await browser.close()
asyncio.get_event_loop().run_until_complete(main())

整合 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 程式碼

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()

中斷網路請求

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_()

記錄並繼續所有網路請求

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