js_reverse/AST抽象语法树/5.AST操作之API用法-path路径/decode_obfuscator.js

const fs = require('fs');
const {parse} = require("@babel/parser");
const traverse = require("@babel/traverse").default;
const generator = require("@babel/generator").default;
let encode_file = "./encode.js";

let js_code = fs.readFileSync(encode_file, {encoding: "utf-8"});
let ast = parse(js_code);

const visitor = {
    enter(path)
    {
        if(path.isNumericLiteral())
        {
            path.remove()
        }
    },
}

traverse(ast, visitor);

// 写入文件
let {code} = generator(ast);
console.log(code)
fs.writeFile('decode.js', code, (err) => {});
