使用requests+pyquery爬取dd373地下城跨五最新商品信息

废话不多说直接上代码：

　　可以使用openpyel库对爬取的信息写入Execl表格中代码我就不上传了

import requests
from urllib.parse import urlencode
from requests import RequestException
from pyquery import PyQuery as pq

    #获取dd373html信息

    }
    data = {
        "minPrice":333,
        "maxPrice":""
    }

    try:
        response = requests.get(url,headers=headers)
        if response.status_code == 200:
            return response.text
        return None
    except RequestException:
        print("链接错误",url)
        return None
