Python3爬虫爬取百姓网列表并保存为json功能示例【基于request、lxml和json模块】

import requests
from lxml import etree
import json
#构造头文件，模拟浏览器访问

response=requests.get(url,headers=headers)
body=response.text #获取网页内容
html=etree.HTML(body,etree.HTMLParser())
gethtml=html.xpath('//div[contains(@class,"media-body-title")]')
# 存储为数组list

# 保存为json
