请求返回的一堆乱七八糟的字符就是加密过后的数据。(当然了,你服务器给我加密后的数据,你想要展示到浏览器页面上肯定需要本地解密数据,你肯定不会把这一堆乱码展示出来的。

在这里插入图片描述

  • 那么我们就需要去找对应的 js 解密流程。

在这里插入图片描述

通过九牛二虎之力终于找到了解密的地方,这一步是最耗时,最容易秃头的步骤。

在这里插入图片描述

找逆向切入点主要方法有:

  • 关键字搜索,打断点调试
  • 利用XHR设置断点;
  • 查看调用栈。

这个网页我是通过打XHR断点 + 搜索关键字decrtpt(解密)的方式找到了这个加密处。

来看看调试出来的数据吧~

从上面的图片,我们可以知道解密流程是由一个h函数实现的,h 函数把传进来的参数t(就是那一大串加密的字符),通过AES解密后返回了一个json格式的字符串,这就是我们想要的数据了。

下面我们开始用 python 去模拟这一流程:

在这里插入图片描述

OK,我们可以通过 requests 获得加密后的数据了,下面的步骤就是将字符解密。

在这里插入图片描述

这是逆向过程中第二费时的步骤,抠网页中的 js 代码然后用pyexecjs模块去执行获得解密数据; 或者将网页中的 js 代码用
python 进行重写(就是把 js 代码逻辑改成 python 的)。

在这里插入图片描述

据我所学知识看来,这是个AES加密,模式是CBC,填充模式是Pkcs7,只要再知道偏移量iv和密钥key是多少,这个解密流程就能被完全突破了,按照函数的位置参数来看,f对应的就是秘钥key

在这里插入图片描述

得来全不费工夫~~~就在上面挨着,拿到密钥和vi之后,就可以使用Python中的Crypto模块进行AES解密。详细代码如下:

import requests
from Crypto.Cipher import AES
from binascii import b2a_hex, a2b_hex


# 向url发起请求,参数page_num为请求的页码数
def request(page_num):
  headers = {
    'Connection': 'keep-alive',
    'Pragma': 'no-cache',
    'Cache-Control': 'no-cache',
    'Accept': 'application/json, text/plain, */*',
    'timeout': '30000',
    'accessToken': '',
    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/88.0.4324.104 Safari/537.36',
    'Referer': 'http://jzsc.mohurd.gov.cn/data/company',
    'Accept-Language': 'zh-CN,zh;q=0.9',
  }

  params = (
    ('pg', page_num),
    ('pgsz', '15'),
    ('total', '450'),
  )
  response = requests.get('http://jzsc.mohurd.xxx.cn/api/webApi/dataservice/query/comp/list', headers=headers, params=params, verify=False)
  return response.text


# 对请求回来的响应数据进行解密,参数text为响应数据
def decrypt(text):
  key = 'jo8j9wGw%6HbxfFn'.encode('utf-8')  //密钥
  iv = '0123456789ABCDEF'.encode('utf-8')  //加密偏移量
  mode = AES.MODE_CBC      //加密模式
  cryptos = AES.new(key, mode, iv)
  plain_text = cryptos.decrypt(a2b_hex(text))
  return bytes.decode(plain_text).rstrip('')

# 获取数据,我们观察下打印的数据是否为解密的数据就可以了
def get_data():
  for i in range(3):
    print(decrypt(request(str(i))))

if __name__ == '__main__':
  get_data()

执行代码后,我们得到网页上的数据了:
