Playwright

Playwright 模块提供了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：

同步

from playwright.sync_api import sync_playwright, Playwright

def run(playwright: Playwright):
    chromium = playwright.chromium # 或者 "firefox" 或 "webkit"。
    browser = chromium.launch()
    page = browser.new_page()
    page.goto("http://example.com")
    # 其他操作...
    browser.close()

with sync_playwright() as playwright:
    run(playwright)

异步

import asyncio
from playwright.async_api import async_playwright, Playwright

async def run(playwright: Playwright):
    chromium = playwright.chromium # 或者 "firefox" 或 "webkit"。
    browser = await chromium.launch()
    page = await browser.new_page()
    await page.goto("http://example.com")
    # 其他操作...
    await browser.close()

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

方法

stop

v1.9 之前添加 playwright.stop

如果 Playwright 实例是在未使用 Python 上下文管理器的情况下创建的，可以通过该方法终止此 Playwright 实例。这在 REPL 应用场景下非常有用。

from playwright.sync_api import sync_playwright

playwright = sync_playwright().start()

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

playwright.stop()

用法

playwright.stop()

返回值

• NoneType#

属性

chromium

v1.9 之前添加 playwright.chromium

该对象可用于启动或连接到 Chromium，返回 Browser 实例。

用法

playwright.chromium

类型

devices

v1.9 之前添加 playwright.devices

返回一个设备字典，可用于 browser.new_context() 或 browser.new_page()。

同步

def run(playwright: Playwright):
    webkit = playwright.webkit
    iphone = playwright.devices["iPhone 6"]
    browser = webkit.launch()
    context = browser.new_context(**iphone)
    page = context.new_page()
    page.goto("http://example.com")
    # 其他操作...
    browser.close()

with sync_playwright() as playwright:
    run(playwright)

异步

import asyncio
from playwright.async_api import async_playwright, Playwright

async def run(playwright: Playwright):
    webkit = playwright.webkit
    iphone = playwright.devices["iPhone 6"]
    browser = await webkit.launch()
