Playwright

Playwright 模組提供啟動瀏覽器實例的方法。以下是使用 Playwright 驅動自動化的典型範例

同步

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)

非同步

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

stop

在 v1.9 之前新增 playwright.stop

如果 Playwright 的此實例是繞過 Python 內容管理器建立的，則終止此實例。這在 REPL 應用程式中很有用。

from playwright.sync_api import sync_playwright

playwright = sync_playwright().start()

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

playwright.stop()

用法

playwright.stop()
