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
}
