pyppeteer: 得到当前运行中的浏览器

一，代码：

import requests
from requests.exceptions import HTTPError
from pyppeteer.launcher import connect

def get_debugger_url():
    url = "http://localhost:9222/json/version"
    try:
        resp = requests.get(url).json()
        print(resp)
        if resp['webSocketDebuggerUrl'] is None:
            raise Exception(resp['msg'])
        webSocketDebuggerUrl = resp['webSocketDebuggerUrl']
        return webSocketDebuggerUrl
    except HTTPError:
        raise Exception(HTTPError.response)

async def get_browser():
    debugUrl = get_debugger_url()
    print(debugUrl)
    browser = await connect(
                browserWSEndpoint=debugUrl,
                defaultViewport=None,
                ignoreHTTPSErrors=True,
                ignoreDefaultArgs=['--enable-automation'],
                logLevel=3
            )
    return browser

二，调用：

import debugbrowser
import asyncio

URL = 'https://movie.douban.com/explore?support_type=movie&is_all=false&category=%E7%83%AD%E9%97%A8&type=%E5%85%A8%E9%83%A8'

async def main():
    browser = await debugbrowser.get_browser()
    print(browser)
    page = await browser.newPage()
    await page.goto(URL, options={'timeout': 30000})
    await page.evaluate('''()=>{Object.defineProperties(navigator,{webdriver:{get:()=>false}})}''')
    await asyncio.sleep(7)
    doc1 = await page.content()
    print(doc1)

if __name__ == '__main__':
    asyncio.get_event_loop().run_until_complete(main())
