问题遇到的现象和发生背景

为什么爬虫没法获得网页源代码？

用代码块功能插入代码，请勿粘贴截图

import requests
headers = {'User-Agent':'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/80.0.3987.87 Safari/537.36 SE 2.X MetaSr 1.0'}
url = 'https://www.baidu.com/s?rtt=1&bsst=1&cl=2&tn=news&ie=utf-8&word=阿里巴巴'
res = requests.get(url, headers=headers)
res.encoding = 'utf-8'

print(res.text)

运行结果及报错内容

我想要达到的结果

想知道为什么不对，该怎么改

不去控制台看真实请求接口 这能行吗
cookie换成你的

import requests

headers = {
