通过修改User-Agent值达到浏览器伪装

# 浏览器伪装

import urllib.request

url = "https://blog.csdn.net/weixin_42760923"
res = urllib.request.urlopen(url).read().decode("utf-8")
# 头文件格式header=("User-Agent","具体用户代理值")
headers = ("User-Agent",
           "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/79.0.3945.79 Safari/537.36")
opener = urllib.request.build_opener()
data = opener.open(url).read()
with open("../伪装浏览器.html", "wb") as f:
    f.write(data)
