分析

参数中password和challenge看起来是加密参数，其实challenge是极验验证码请求的参数，本文针对password进行参数分析，暂时先不做讨论。

搜索login/login.json并格式化js后，发现改password通过md5实现加密，在Watch界面输入g查看g的内容

放行程序后，在g.isValidate && (g.password = md5(g.password)处重新打上断点并登录

那么分析得出password=md5(“veenike”+md5(passwrod)+”veenike”)

爬虫实现

plain

import requests
from hashlib import md5

username = '15806204095'
pwd = '123'
md5_pwd = md5(("veenike" + md5(pwd.encode('utf8')).hexdigest() + "veenike").encode("utf8")).hexdigest()
print(md5_pwd)
url = 'https://passport.lagou.com/login/login.json?jsoncallback=jQuery111306946515748870927_1618229101639&isValidate=true&username='+username+'&password=+'+md5_pwd+'+&request_form_verifyCode=&challenge=c3bebcad0648898aa58cb3f4dbf2f820&_=1618229101642'
r =requests.get(url)
print(r.text)
