Playwright

Playwright 模块提供了一种启动浏览器实例的方法。以下是使用 Playwright 进行自动化操作的典型示例：

🌐 Playwright module provides a method to launch a browser instance. The following is a typical example of using Playwright to drive automation:

Sync

from playwright.sync_api import sync_playwright, Playwright

def run(playwright: Playwright):
    chromium = playwright.chromium # or "firefox" or "webkit".
    browser = chromium.launch()
    page = browser.new_page()
    page.goto("http://example.com")
    # other actions...
    browser.close()

with sync_playwright() as playwright:
    run(playwright)

Async

import asyncio
from playwright.async_api import async_playwright, Playwright

async def run(playwright: Playwright):
    chromium = playwright.chromium # or "firefox" or "webkit".
    browser = await chromium.launch()
    page = await browser.new_page()
    await page.goto("http://example.com")
    # other actions...
    await browser.close()

async def main():
    async with async_playwright() as playwright:
        await run(playwright)
asyncio.run(main())

方法

🌐 Methods

stop

Added before v1.9 playwright.stop

在绕过 Python 上下文管理器创建 Playwright 实例的情况下终止该实例。这在 REPL 应用中很有用。

🌐 Terminates this instance of Playwright in case it was created bypassing the Python context manager. This is useful in REPL applications.

from playwright.sync_api import sync_playwright

playwright = sync_playwright().start()

browser = playwright.chromium.launch()
page = browser.new_page()
page.goto("https://playwright.nodejs.cn/")
page.screenshot(path="example.png")
browser.close()

playwright.stop()
