目标要求

抓取所有(5页)机票的价格，并计算所有机票价格的平均值，填入答案。

网站分析

这种js逆向的问题, 首先要打开开发者工具(控制台), 刷新网页, 很明显这个地址, 就是我们要破解的url

https://match.yuanrenxue.com/api/match/1?m=376ce684e9277c7203c34508d4f1c705%E4%B8%A81636883345

点击下一页, 看看有没有什么规律, 看起来页数和m的值是变化的, 页数暂时不用管, 那m的值就是我们需要破解的参数

找到目标后, 接下来就是找加密的js代码, 首先就是搜索关键字, 我们先来搜索m=, 看搜索结果第一个比较像, 点进去后发现并不是想要的

再来看看m参数, 长这个样子

c9d12a0dbcdd7c26a7abb5913dae7745丨1636883488

搜一下关键字丨, 注意是中文字符的丨, 结果显示也没有

接下来换个思路找, 查看这个url的请求堆栈

看到前两个请求调用的jquery的两个函数, 直接点第三个, 可以看到是一行无法自动格式化的js代码

把它复制出来找个第三方工具, 格式化一下, 我用的Chrome插件(FeHelper), 格式化后, 会看到一行混淆后的js

再把它复制出来, 用猿人学的工具(http://tool.yuanrenxue.com/deobfuscator)来解一下混淆js代码

这下就明白为什么搜丨, 搜不来了, 是给混淆了, 可以清楚的看到这个m是由oo0O0函数 + window.f + '丨' + _0x2268f9(Date.parse(new Date()) + 100000000) / 1000组成的

接下来就是, 破解这段代码的各个参数, 哪里不明白的直接在控制台测试一下,

但是这个网站的一打开控制台就是无限的debugger, 先把这个烦人的无限的debugger关掉, 点击输出这行内容的js代码

然后右击选中行, 选择一律不在此处暂停(Never pause here)选项

然后看代码, 一个个解密参数

_0x2268f9: 是一个时间戳

oo0O0 函数: 在页面中一下就能看到

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)}var U = ['W5r5W6VdIHZcT8kU', 'WQ8CWRaxWQirAW=='];var J = function (o, E) {o = o - 0x0;var N = U[o];if (J['bSSGte'] === undefined) {var Y = function (w) {var m = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789+/=',T = String(w)['replace'](/=+$/, '');var A = '';for (var C = 0x0, b, W, l = 0x0; W = T['charAt'](l++); ~W && (b = C % 0x4 ? b * 0x40 + W : W, C++% 0x4) ? A += String['fromCharCode'](0xff & b >> (-0x2 * C & 0x6)) : 0x0) {W = m['indexOf'](W)}return A};var t = function (w, m) {var T = [],A = 0x0,C, b = '',W = '';w = Y(w);for (var R = 0x0, v = w['length']; R < v; R++) {W += '%' + ('00' + w['charCodeAt'](R)['toString'](0x10))['slice'](-0x2)}w = decodeURIComponent(W);var l;for (l = 0x0; l < 0x100; l++) {T[l] = l}for (l = 0x0; l < 0x100; l++) {A = (A + T[l] + m['charCodeAt'](l % m['length'])) % 0x100, C = T[l], T[l] = T[A], T[A] = C}l = 0x0, A = 0x0;for (var L = 0x0; L < w['length']; L++) {l = (l + 0x1) % 0x100, A = (A + T[l]) % 0x100, C = T[l], T[l] = T[A], T[A] = C, b += String['fromCharCode'](w['charCodeAt'](L) ^ T[(T[l] + T[A]) % 0x100])}return b};J['luAabU'] = t, J['qlVPZg'] = {}, J['bSSGte'] = !![]}var H = J['qlVPZg'][o];return H === undefined ? (J['TUDBIJ'] === undefined && (J['TUDBIJ'] = !![]), N = J['luAabU'](N, E), J['qlVPZg'][o] = N) : N = H, N};eval(atob(window['b'])[J('0x0', ']dQW')](J('0x1', 'GTu!'), '\x27' + mw + '\x27'));return ''
}

现在可以确定mw是一个字符串时间戳, 把js代码放在本地跑一下, 看一下相关的参数

这里我用的是js2py, 完全不依赖js环境, 直接将js代码转为python代码执行, 但是缺点也很明显, 没有那么完整的js环境, 缺少的需要自己补齐

import js2py
import timejs = js2py.EvalJs()
js.execute(open("oo0O0.js", encoding="utf-8").read())
js.oo0O0(str(int(time.time()) * 1000 + 100000000))

一运行就会报错

js2py.internals.simplex.JsException: TypeError: Undefined and null dont have properties (tried getting property 'length')

看一下js, 是window.a那里报的错, 是因为没有定义window.a这个变量, 从控制台找出来补上, 顺便把其它的几个也补上

因为js2py运行有document依赖的代码会报错, 所以在代码里面将document的属性, 写到windows里面(或者直接定义为变量), 代码也要改一下

这时候在此运行会发现, 到最后一行报错了, 这是因为js2py没有atob函数

js2py.internals.simplex.JsException: ReferenceError: atob is not defined

先来看一下, eval最后一行的各个组成打印一下

"window['b']"

'replace'
"J('0x1', 'GTu!')"
'mwqqppz'
"''' + mw + '''"
"'1636895868000'"

明白了各个部分, 可以把这行js变一下

eval(atob(window['b'])[J('0x0', ']dQW')](J('0x1', 'GTu!'), 'x27' + mw + 'x27'));

改成这样

eval(atob(window['b'])['replace']('mwqqppz', mw));

再来看一下atob(window['b']) 是个啥结果

既然atob本地会报错, 那就放到控制台执行一下

格式化一下, 可以看到是一个md5加密, 最后赋值给了window.f

到这里基本就明白了, 其实就是把 md5字符串js 的 mwqqppz 替换成了 mw, 然后eval执行了 hex_md5(mw), 最后赋值给了 window.f

简化一下m参数的加密代码

m = window.f + '丨' + _0x2268f9 / 1000;

也就是

m = hex_md5(_0x2268f9) + '丨' + _0x2268f9 / 1000;

接下来只需要用python实现, 然后测试就行了✌️
