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 驱动自动化的典型示例：

Sync

from playwright.sync_api import sync_playwright

def run(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

async def run(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())

• playwright.chromium
• playwright.devices
• playwright.firefox
• playwright.request
• playwright.selectors
• playwright.stop()
• playwright.webkit

playwright.stop()

Added in: v1.8

• returns: <NoneType>#

终止此 Playwright 实例，以防它是绕过 Python 上下文管理器创建的。这对 REPL 应用程序很有用。

>>> from playwright.sync_api import sync_playwright

>>> playwright = sync_playwright().start()

>>> browser = playwright.chromium.launch()
>>> page = browser.new_page()
>>> page.goto("http://whatsmyuseragent.org/")
>>> page.screenshot(path="example.png")
>>> browser.close()

>>> playwright.stop()

playwright.chromium

Added in: v1.8

• type: <BrowserType>

此对象可用于启动或连接到 Chromium，返回 Browser 的实例。

playwright.devices

Added in: v1.8

• type: <Dict>

返回用于 browser.new_context(**kwargs) 或 browser.new_page(**kwargs) 的设备字典。

Sync

from playwright.sync_api import sync_playwright

def run(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")
    # other actions...
    browser.close()

with sync_playwright() as playwright:
    run(playwright)

Async

import asyncio
from playwright.async_api import async_playwright

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

playwright.firefox

Added in: v1.8

• type: <BrowserType>

此对象可用于启动或连接到 Firefox，返回 Browser 的实例。

playwright.request

Added in: v1.16

• type: <APIRequest>

公开用于 Web API 测试的 API。

playwright.selectors

Added in: v1.8

• type: <Selectors>

Selectors 可用于安装自定义选择器引擎。有关详细信息，请参阅使用选择器。

playwright.webkit

Added in: v1.8

• type: <BrowserType>

此对象可用于启动或连接到 WebKit，返回 Browser 的实例。
