用法

playwright 同步

from playwright.sync_api import sync_playwright
with sync_playwright() as p:
    browser = p.chromium.launch(headless=False，slow_mo=50)
    page = browser.new_page()
    page.goto("https://www.baidu.com")
    print(page.title())
    browser.close()

headless=False 不使用无头浏览模式，

slow_mo=50 执行速度

playwright 异步

import asyncio
from playwright.async_api import async_playwright

async def main():
    async with async_playwright() as p:
        browser = await p.chromium.launch()
        page = await browser.new_page()
        await page.goto("http://playwright.dev")
        print(await page.title())
