2023 js逆向爬虫 有道翻译 代码

前置条件：nodejs环境、安装  crypto 和  python3环境

js.js文件：

const crypto = require("crypto")function decode(resp_data) {g_o = 'ydsecret://query/key/B*RGygVywfNBwpmBaZg*WT7SIOUP2T0C9WHMZN39j^DAdaZhAnxvGcCY6VYFwnHl'g_n = 'ydsecret://query/iv/C@lZe2YzHtZ2CYgaXKSVfsb7Y4QWHjITPPZ0nQp87fBeJ!Iv6v^6fvi2WN@bYpJ4'const g_o_1 = new Uint8Array(crypto.createHash('md5').update(g_o).digest())const g_n_1 = new Uint8Array(crypto.createHash('md5').update(g_n).digest())const cipher = crypto.createDecipheriv('aes-128-cbc', g_o_1, g_n_1)let s = cipher.update(resp_data, 'base64', 'utf-8')s += cipher.final("utf-8")return s
}
