本文介绍了使用Python实现有道翻译API的过程，包括关键参数如salt、ts、sign的生成方法，涉及requests、json、random、time和hashlib等模块。通过将JavaScript代码转换为Python代码，成功实现了翻译功能，并提供了封装的MD5加密方法。

import hashlib
import json
import random
import time

import requests

base_url = 'http://fanyi.youdao.com/translate_o?smartresult=dict&smartresult=rule'
headers = {
    'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/73.0.3683.86 Safari/537.36',

    md5.update(bytes(value,encoding='utf-8'))
    return md5.hexdigest()

# print(response.text)

json_data = json.loads(response.text)
for data in json_data['smartResult']['entries']:
    result+=data
print(result)

有道翻译有变化参数三个：salt、ts、sign
用到了五个模块
requests,json,random,time,hashlib
js中源代码：salt = “” + (new Date).getTime()+parseInt(10 * Math.random(), 10)
转换成python：salt=str(time.time()*1000+random.randint(1,10))
源代码：ts = (new Date).getTime()
转换成python：ts=str(time.time()*1000)
源代码：sign: n.md5(“fanyideskweb” + e + i + “n%A-rKaT5fb[Gy?;N5@Tj”)
转换：sign = n.md5(“fanyideskweb” + kw + salt + “n%A-rKaT5fb[Gy?;N5@Tj”)
封装md5方法
def get_md5(value):
md5 = hashlib.md5()
md5.update(bytes(value,encoding=‘utf-8’))
return md5.hexdigest()
sign获取md5方法
sign=get_md5(value)
for循环中json_data中里面包含smartResult,而smartResult中包含entries，所有取其索引完成翻译
