抓包

本登录页面既然是框架，找到php页面，https://service.zol.com.cn/user/siteLogin.php?type=small&callback=userLoginCallback&backurl=https://www.zol.com.cn/

直接访问该php网址，避免其他请求干扰分析

登录url:

https://service.zol.com.cn/user/ajax/siteLogin/login.php

分析

全局搜索siteLogin/login.php

中关村非常的耿直，加密使用md5,var md5Password = CryptoJS.MD5(password+"zol") + '';输入123提交的pwd为74ce2ba17b2c218246e778fb5e895c95，通过md5比对

爬虫实现

拷贝Form Data到请求头加引号.py中自动生成dict格式

import requests
from hashlib import md5

username = '15806204095'
pwd = '123'
md5_pwd = md5((pwd + 'zol').encode('utf8')).hexdigest()
print(md5_pwd)
url = 'https://service.zol.com.cn/user/ajax/siteLogin/login.php'
data = {
    'userid': username,
    'pwd': md5_pwd,
    'isAuto': '1',
    'backurl': 'http://www.zol.com.cn/',
    'tmallBtn': '0',
    'activeBtn': '0',
    'headPicid': '0',
}
r =requests.post(url,data)
print(r.text)
