通过接口,找到代码的位置

接口地址:http://match.yuanrenxue.com/api/match/16?page=2&m=dAd4i5nAPW2EdCTf7d63700a1da4c93eda8085862b8894eKd2P5MkhP8&t=1619875465000

有三个参数:

image.png

p_s 就是时间戳

就剩下一个 参数 m

image.png

经过调试,n[e(528)] 解析之后,就是函数 t[e(528)]

传过去两个参数,btoa 是自定义的函数,还有一个时间戳

在 t[e(528)]函数中,其实返回的是 btoa(p_s)

找到 btoa 函数

一步一步调试,将需要的函数 单独放到一个 js 文件,手动调用结果

mark 一下

1、

在调试过程中发现了几个个很坑的地方。

比如这里,当你把所有的报错信息 都解决了之后,能生成 m 参数,但是去请求接口的时候,提示参数校验不对。

在 try{} 中的代码,如果有某个函数不存在或发送异常,就会终止运行 try 中的代码,去运行 catch 中的代码

然而 catch 中的代码是可以执行成功的

如果调试不细心,观察不仔细,就会遇到,虽然能获取到 m 参数,但是参数始终校验错误。

这里 会找不到 n 函数,需要去找真正的 n 函数

2、

var a = [1, 2, 3]
let num = a.shift()  // 弹出 第一个元素 1
a.push(num)  // 在最后 填入一个元素,
a: [2, 3, 1]

如果这些函数不熟悉,会很难发现 一些装着常量的 list,在运行的时候 用这些函数, 来打乱元素的顺序

调试之后,整理的 js 文件
