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 connectdef 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 webSocketDebuggerUrlexcept 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 asyncioURL = '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())
