以下代码取的是院校专业分数线
推断参数含义
signsafe 数据加密签名获取
搜索 锁定 signsafe 字段以及加密
以上看到，t就是请求中的signsafe参数。而且，函数中也出现了HmacSHA1、base64等方法。由此可知，定位的加密位置是正确的。接下来需要将加密函数抠下来改写，方便调用。下断点继续跟踪方法调用。跟踪v.a.enc.Utf8.parse方法，如下多次尝试, 最终试出
var CryptoJS = require("crypto-js");
function signsafe_jami(p) {
p = p.replace(/^\/|https?:\/\/\/?/, "");
p = p.replace(/%2F/g, "/");
console.log(p)
let f = CryptoJS.HmacSHA1(CryptoJS.enc.Utf8.parse(p), "D23ABC@#56");
f = CryptoJS.enc.Base64.stringify(f).toString();
f = CryptoJS.MD5(f).toString();
return f;
}
url = "https://api.eol.cn/web/api/?local_batch_id=14&local_province_id=31&local_type_id=3&page=1&school_id=31&size=100&special_group=&uri=apidata%2Fapi%2Fgk%2Fscore%2Fspecial&year=2021"
console.log(signsafe_jami(url))
开始前 先安装 npm install crypto-js
data 解析
通过以上 signsafe 访问文章开头接口, 拿到一长串 data 数据(见开头图2)
从 method 知道使用的是 aes-256-cbc的方式进行加密, 推出加密方法是aes-256， 密钥长度256位，cbc指的是在加密和解密是需要一个初始化向量(Initialization Vector, IV)，在每次加密之前或者解密之后，使用初始化向量与明文或密文异或。说白了，就是设定的密钥，添加一个初始化偏移量。加密时，明文先与iv偏移量异或，再将结果进行256位的块加密，得到的输出就是密文，同时本次的输出密文作为下一个块加密的IV。
通过搜索 aes 确定疑似代码 进行仿写

最终完结, 又因为偷懒 想直接部署到服务器
使用 express 部署 (第一次写 代码像 ? 一样)
npm install express
npm install body-parser
npm install cors --save
npm install crypto-js
index.js
/* 引入express框架 */
const express = require('express');
const app = express();
/* 引入cors */
const cors = require('cors');
app.use(cors());
/* 引入body-parser */
const bodyParser = require('body-parser');
const CryptoJS = require("crypto-js");
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({extended: false}));
const {get_data} = require("./data_decode.js");
app.all('*', function (req, res, next) {
if (!req.get('Origin')) return next();
// use "*" here to accept any origin
res.set('Access-Control-Allow-Origin', '*');
res.set('Access-Control-Allow-Methods', 'GET');
res.set('Access-Control-Allow-Headers', 'X-Requested-With, Content-Type');
// res.set('Access-Control-Allow-Max-Age', 3600);
if ('OPTIONS' == req.method) return res.send(200);
next();
});
app.get('/', (req, res) => {
res.send('<p style="color:red">服务已启动</p>');
})
// get接收前端传递过来的参数
app.post("/api/post/signsafe",(req,res)=>{
let url = req.body.url; // 接收前端传递过来的参数
console.log(url)
let obj = {
code: 2000,
status: 'ok',
data: signsafe_jami(url)
}
res.send(obj)
})
app.get("/api/get/signsafe",(req,res)=>{
let url = req.query.url; // 接收前端传递过来的参数
console.log(url)
let obj = {
code: 2000,
status: 'ok',
data: signsafe_jami(url)
}
res.send(obj)
} )
app.post("/api/post/data",(req,res)=>{
console.log(req.body);
let data = req.body.data; // 接收前端传递过来的参数
let obj = {
code: 2000,
status: 'ok',
data: get_data(data)
}
res.send(obj)
})
/* 监听端口 */
app.listen(3000, () => {
console.log('listen:3000');
})
function signsafe_jami(p) {
p = p.replace(/^\/|https?:\/\/\/?/, "");
p = p.replace(/%2F/g, "/");
console.log(p)
let f = CryptoJS.HmacSHA1(CryptoJS.enc.Utf8.parse(p), "D23ABC@#56");
f = CryptoJS.enc.Base64.stringify(f).toString();
f = CryptoJS.MD5(f).toString();
return f;
}
data_decode.js
exports.get_data = AES_Decrypt
var CryptoJS = require("crypto-js");
var key = CryptoJS.enc.Hex.parse("4587dc9b6a7c3e9ef3b920f994edc3a210c460977528138d41e58b9b02c94ffd");
var iv = CryptoJS.enc.Hex.parse("6aa677d0f4d6646eec5e9a82aedb60b0");
console.log(key);
console.log(iv);
function AES_Decrypt(word) {
var srcs = CryptoJS.enc.Base64.stringify(CryptoJS.enc.Hex.parse(word));
var decrypt = CryptoJS.AES.decrypt(srcs, key, {
iv: iv,
mode: CryptoJS.mode.CBC,
padding: CryptoJS.pad.Pkcs7
});
return decrypt.toString(CryptoJS.enc.Utf8);
}
最后记录一下最开始的解密 data 代码 ()
Tips: 只能说 可以实现 但没必要
exports.get_data = get_data
var CryptoJS = CryptoJS || (function (Math, undefined) {
var C = {};
