1、非常简单js混淆

• 试题连接:http://match.yuanrenxue.com/match/12

m的值是base64加密

解决方法：

import base64
import requests
import time
# http://match.yuanrenxue.com/api/match/12?page=1&m=eXVhbnJlbnh1ZTE%3D
sum = 0
for i in range(5):
    time.sleep(0.3)
    m = 'yuanrenxue'+str(i+1)
    m = base64.b64encode(m.encode('utf-8'))
    m = m.decode('utf-8')
    print(m)
    header = {
        'User-Agent': 'yuanrenxue.project',
        'Cookie': 'Hm_lvt_c99546cf032aaa5a679230de9a95c7db=1614301813; no-alert2=true; sessionid=7zw5agrizbkl4mfr2sbbsl8eu87fp89p; yuanrenxue_cookie=1615427946|OQ627PFzh1ka4yQF1jYvRpo3qEjjafxRaWGwpyCFr9UmrowVRUpUR4U3LoIdHBomSiNDxq5PUtjtrcAgfTAK9vMfPw1fxMaFSGkb3KVWZPDRkWFKU9P1f6Df8Cq4p5mTSkuOYXhkXCs08Vs3nzC3Oiobi0p2kEZM4fph9cSUw0; Hm_lpvt_c99546cf032aaa5a679230de9a95c7db=1615428833'
    }
    url = 'http://match.yuanrenxue.com/api/match/12?page='+str(i+1)+'&m='+m
    r = requests.get(url, timeout=(2, 2), headers=header)
    r = r.json()
    data = r['data']
    for value in data:
        num = value['value']
        sum = sum + num
print(sum)

2、雪碧图、样式干扰 css加密

• 试题连接:http://match.yuanrenxue.com/match/4

查看数字的样式为图片
接口中发现返回的数据图片的数据
数据里面包含干扰图片
干扰图片分别又px偏移和html页面代码中的style属性决定

3、js混淆源码乱码

• 试题连接:http://match.yuanrenxue.com/match/1

• f12跳过条件断点，查看接口连接发现有特殊m值 查找m值成为解决问题关键
• 在页面源码发现‘m=var m =oo0O0(timestamp.toString()) + window.f;’关键字，拷贝该部分页面源码到js文件格式化的辅助软件查看
• 在源码中找到function oo0O0(mw)方法，同时分析window.b发现其为固定值，在接口中得到该值替换掉求window.b的代码
• 根据function oo0O0(mw)方法中的eval函数知道其中包含某个表达式并返回值，通过node.js模拟得到window.j的方法
• 最后通过拼接得到yuanrenxue1.js文件，用yuanrenxue1.py文件驱动yuanrenxue1.js求得其解

解决办法：
yuanrenxue1.js文件：

const jsdom = require('jsdom');
const {JSDOM} = jsdom;
const document = new JSDOM('
hello world
')
window = document.window;

function oo0O0(mw) {
    // window.b = '';
    // for (var i = 0, len = window.a.length; i < len; i++) {
    //     console.log(window.a[i]);
    //     window.b += String[document.e + document.g](window.a[i][document.f + document.h]() - i - window.c)
    // }
    window.b =

4、js混淆动态cookie

• 试题连接:http://match.yuanrenxue.com/match/2

• 打开试题链接F12后发现刷新后的页面会反复请求页面地址2次之后才会返回页面数据
• 同时在接口的链接中发现了cookie值中带有会变化的m值，查找m值便是问题的关键
• 模拟请求页面数据发现返回了js代码，查看js代码被ob加密过，说明大概率就跟cookie加密有关了，代码中的‘document[“cookie”] = “m” + M() + “=” + V(Y) + “|” + Y + “; path=/”;’便是需要m值生成方式
• 利用node.js环境模拟运行返回的js代码得到m值，最后编写two.py文件驱动two.js文件获取试题接口返回的数据

5、访问逻辑

• 试题连接:http://match.yuanrenxue.com/match/3

• f12后观察发现翻页数据请求会返回log和page两个信息
• 并且并没有什么关键参数，于是尝试分别先后request.get返回的log和page并打印page文本信息
• page返回的文本数据是js代码，分析发现eval关键字，复制js代码到浏览器console运行，再讲eval运行一遍
• eval同样返回了一个js代码，代码中有document.cookie关键字，复制关键字到浏览器打印其返回值，得到cookie值
• 对比接口的cookie值发现少了sessionid，所以并没有用
• 最后分析访问逻辑，在request.get时需要带上具有一定规律的header头

解决办法：

import requests
for i in range(5):
    s = requests.session()
    header = {
        'Host': 'match.yuanrenxue.com',
