代码在后面
思路1总结 抓包找到这四个加密参数
‘salt’: salt,
‘sign’: sign,
‘ts’: ts,
‘bv’: bv,
得到四个值（涉及到js中 MD5， 时间戳。 随机数等）
携带这四个值去发送请请求， 携带cookies referer User-Agent
var r = function(e) {var t = n.md5(navigator.appVersion), r = "" + (new Date).getTime(), i = r + parseInt(10 * Math.random(), 10);return {ts: r,bv: t,salt: i,sign: n.md5("fanyideskweb" + e + i + "n%A-rKaT5fb[Gy?;N5@Tj")}};
分析可知salt 是i， 而i是 r + 一个(0,9)的随机数， r 是时间戳
ts 是 r 时间戳
navigator.appVersion 是User-Agent
断点可以看得出来e 是传的参数 i=‘hello’ 要翻译的内容
思路2总结: 用execjs执行js文件
import execjs
with open(‘youdao.js’, ‘r’, encoding=‘utf-8’) as r:
js = r.read()
js = pile(js)
result = js.call(‘function’, ‘apple’)
print(result)

由于时间比较紧，就先给大家分享一种方法，有时间我会继续完成第二种方法代码与大家分享。
