python playwright怎么连接已开启的浏览器

Python Playwright可以使用`connect`方法连接已经打开的浏览器。代码示例：

from playwright.sync_api import Playwright, sync_playwright

async def connect_to_browser(channel: str) -> Playwright:
    playwright = await sync_playwright().start()
    browser = await playwright.connect_over_websocket(url=channel)
    return playwright

# 连接已经打开的浏览器，需要提供 WebSocket URL
playwright = await connect_to_browser("ws://127.0.0.1:1234/devtools/browser/xxxxx")
