前言

记录下如何破cookie逆向

目标

目标网址：https://q.10jqka.com.cn/
目标接口：http://q.10jqka.com.cn/index/index/board/all/field/zdf/order/desc/page/2/ajax/1/
对抗：cookie反爬虫处理，关键字v，如图
在这里插入图片描述

解决步骤

1、JS中关键字查找

如上，我们找到了关键字 v，那么接下来就用hook搜查
点击F12，打开 开发者工具，选择Console直接输入hook代码

(function () {Object.defineProperty(document, 'cookie', {set: function (val) {if (val.indexOf('v') != -1) {debugger;}console.log('Hook捕获到cookie设置->', val);return val;}});
})();# val.indexOf('v') 中输入你要的关键字，回车
# 注意需要等待一会，因为程序加载需要时间
# 回车后，程序执行到v处自动断点，并打印，可一步步向下看js推理

运行后如图，n产出刚好是v的数值

接着点击右上角的箭头，会一步步执行接下来的js
连续点一遍下来发现n值最后由 function D() 产出

全局搜索 function D()，最后输出在这，后面可以创建个空值去接收

2. JS调试技巧

从这里可以发现就是整个的文件只有千多行代码，可以采用全复制方式处理cookie

2.1、扣出所有代码，放入自建js文件中，我这例如: cookie.js

2.2、利用execjs执行

import execjswith open('qq.js', encoding='utf-8') as f:x = f.read()v = execjs.compile(x).call('get_cookie')
print(v)

这时会报错一堆错，而且还要挨个补环境，例如下：

execjs._exceptions.ProgramError: ReferenceError: document is not defined
execjs._exceptions.ProgramError: ReferenceError: window is not defined
execjs._exceptions.ProgramError: ReferenceError: navigator is not defined

这时可以使用 jsdom 这个技术，在 js 文件最上方加入运行js所缺补的环境，例如下（所有通用）

const jsdom = require("jsdom");
const { JSDOM } = jsdom;
const dom = new JSDOM(`<!DOCTYPE html><p>Hello world</p>`);window = dom.window
document = window.document
navigator = window.navigator

官方文档：https://github.com/jsdom/jsdom/wiki/jsdom

然后python代码需要调用其中的函数，获取到产出的v值

1、在 js上面创建 ==》 var _v = {};
2、在 function D() 后面加入.xialuo 接收 ==》 _v.xialuo = D，如图
在这里插入图片描述
3、末尾创建个函数好被python调用

function getCookie() {return _v.xialuo()
}

最后，cookie.js 代码如下：

const jsdom = require("jsdom");
const { JSDOM } = jsdom;
const dom = new JSDOM(`<!DOCTYPE html><p>Hello world</p>`);
window=dom.window;
document=window.document;
navigator=window.navigator;var _v = {}var TOKEN_SERVER_TIME = 1656072000.984;
