    md5.update(s.encode())
    sign = md5.hexdigest()
    params['sign'] = sign

    with open('sign.js', "r", encoding="utf-8") as f:
        data = f.read()
    js = execjs.compile(data)
    return js.call("s", resp.text)

对应 sign.js 中的代码

const crypto = require('crypto');

function g(e) {
    return crypto.createHash("md5").update(e).digest()
}

function s(t) {

    let o = 'ydsecret://query/key/B*RGygVywfNBwpmBaZg*WT7SIOUP2T0C9WHMZN39j^DAdaZhAnxvGcCY6VYFwnHl'
    let n = 'ydsecret://query/iv/C@lZe2YzHtZ2CYgaXKSVfsb7Y4QWHjITPPZ0nQp87fBeJ!Iv6v^6fvi2WN@bYpJ4'

    const a = Buffer.alloc(16, g(o))
        , c = Buffer.alloc(16, g(n))
        , i = crypto.createDecipheriv("aes-128-cbc", a, c);
    let s = i.update(t, "base64", "utf-8");
    return s += i.final("utf-8")

}

测试结果如下：

print(spide_youdao("有道翻译"))
