第四个js逆向项目–全量js文件扣取-一一网

从网站中分析出来js代码执行的部分，然后我们将其提取出来，这个扣取过程教之前更加复杂 , 最后使用的是execjs执行js代码

第一步：熟悉需求

目标网站：unicom_trip.133.cn/city/?syste…

需要的数据的部分

第二步:找到异步加载的接口，分析接口数据

我们看到数据展示到了页面上，我们来找xhr请求

应该就是从这LXA?date=20220303&type=arr请求中获取的数据，我们首先分析有没有加密参数，发现并没有，可以直接请求到拿到数据

当我们看数据的时候，发现数据部分是一串字符串

这里有个技巧可以注意一下：

复制代码

我们可以得到的结论就是，数据被加密了，前端从后端获取到数据后，通过js进行了解密，将数据提取出来放到了页面上，分析js吧

第三步：我们要找到解密js部分

3.1 搜索

我们解析了base64的字符，这样我们有两种选择，我们可以使用技巧，搜索JSON.parse或者直接按照键mac进行搜索

通过json.parse进行搜索，数量太多

我们换mac键试试

3.2 分析js

有个技巧就是：我们搜索到的多个匹配项，我们直觉过滤，然后我们在不能分辨的上面打上断点，刷新页面，看是否经过那个接口，经过，看看和我们的数据是不是相同的，可以快速的选择出我们要找的变量

我们在可疑的地方打上断点

3.3 打上断点，刷新页面调试

详细调试过程上个教程中有，这个部分直接查找进行使用

刷新运行，在第一个断点处，我们发现城市码和城市名称对应的字典，这个对我们后续的数据获取有帮助

在控制台中我们可以获取到cityList,数据太多仅作部分数据的展示

{"999":{"city_code":"999","city_name":"无法区分"},"V0152900":{"city_code":"V0152900","city_name":"阿盟"},"V0152200":{"city_code":"V0152200","city_name":"兴安盟"},"V0150400":{"city_code":"V0150400","city_name":"赤峰"},"V0150100":{"city_code":"V0150100","city_name":"呼和浩特"},"V0152302":{"city_code":"V0152302","city_name":"呼伦贝尔"},"V0152700":{"city_code":"V0152700","city_name":"鄂尔多斯"},"V0152500":{"city_code":"V0152500","city_name":"锡林郭勒"},"V0152800":{"city_code":"V0152800","city_name":"巴彦淖尔"},"V0152600":{"city_code":"V0152600","city_name":"乌兰察布"},...`剩余数据略`}
复制代码

我们跳过第一个断点进入第二个断点，我们发现这个地方就是我们要找的js数据解析的部分

经过在控制台测试，我们可以发现，数据就是通过这个部分解析的，所以接下来就是扣取js的过程了

**改写js **: 对js代码进行简单的整合，变成我们想要的格式

function dataDecode(data){
    var base = new Base64(); 
    var d = JSON.parse(base.decode(data));
    var key = 'UVJgCE+OFIff3hK5BT5sPBbGZzjR6FwntjSCwOA9tUQ=';
    var key1  = CryptoJS.enc.Base64.parse(key);
    var iv1   = CryptoJS.enc.Base64.parse(d.iv);
    var decrypted=CryptoJS.AES.decrypt(d.value,key1,{
        iv : iv1,
        mode : CryptoJS.mode.CBC,
        padding : CryptoJS.pad.Pkcs7
    });
    var d = decrypted.toString(CryptoJS.enc.Utf8);
    return JSON.parse(d);
}
复制代码

3.4 追查相关的js

原则：缺什么补充什么

我们可以新建一个js文件，将刚才的dataDecode函数放入其中，运行代码

# encrypt_data 可以从请求中获取
import execjs
with open("test.js","r",encoding="utf-8") as f:
    str1 = f.read()
ctx = execjs.compile(str1)
a = ctx.call('dataDecode', encrypt_data)
复制代码

我们得到错误 Base64 不存在 ,寻找h方法，查找过程上个教程中有详细陈述

在网页中找到Base64，追加到我们的test.js中

            chr3 = ((enc3 & 3) << 6) | enc4;  
            output = output + String.fromCharCode(chr1);  
            if (enc3 != 64) {

在次运行我们的程序，我们缺失CryptoJS

在网页中进行查找，这个就比较繁琐，首先CryptoJS 是个object , 不能直接跳进去，找到相关文件了，又不知道何处终止

第一个问题，跳不进去—> 解决方式：通过后面的方法parse进入这个文件

第二个问题，不知道何时终止—> 解决方式：依据经验处理(比较抽象)

我们分析下：这个部分实际上就是将CryptoJS对象，使用工厂的方式进行封装

在最后的部分返回了CryptoJS对象

所以经过分析可得中间的所有代码都是CryptoJS对象代码(代码太长了，就不放在笔记中了，只放开始和截至位置)

我们将他放到js文件中，即可

第四步：python获取数据，结合js解密

然后我们通过执行js文件就能对我们获取到的加密数据进行解密了
