python3调用百度翻译API实现实时翻译

今天需要做一个翻译的工具，找到之前写过的有道翻译，已经不能用了，最后看到百度翻译还不错，不过官方版本是python2，我需要python3，就自己写了一个：

# coding: utf8

 说明： appid和secretkey为百度翻译文档中自带的，需要切换为自己的
   python2和python3部分库名称更改对应如下：
   httplib  ----> http.client
   md5   ----> hashlib.md5
   urllib.quote ----> urllib.parse.quote

import http.client
import hashlib
import json
import urllib
import random
 
def baidu_translate(content):
 appid = '20151113000005349'
 secretkey = 'osubcezlgjzvw8qdqc41'
 httpclient = none
 myurl = '/api/trans/vip/translate'
 q = content
 fromlang = 'zh' # 源语言
 tolang = 'jp' # 翻译后的语言
 salt = random.randint(32768, 65536)
 sign = appid + q + str(salt) + secretkey
 sign = hashlib.md5(sign.encode()).hexdigest()
 myurl = myurl + '?appid=' + appid + '&q=' + urllib.parse.quote(
  q) + '&from=' + fromlang + '&to=' + tolang + '&salt=' + str(
  salt) + '&sign=' + sign
 
 try:
  httpclient = http.client.httpconnection('api.fanyi.baidu.com')
  httpclient.request('get', myurl)
  # response是httpresponse对象
  response = httpclient.getresponse()
  jsonresponse = response.read().decode("utf-8")# 获得返回的结果，结果为json格式
  js = json.loads(jsonresponse) # 将json格式的结果转换字典结构
  dst = str(js["trans_result"][0]["dst"]) # 取得翻译后的文本结果
  print(dst) # 打印结果
 except exception as e:
  print(e)
 finally:
  if httpclient:
   httpclient.close()
 
if __name__ == '__main__':
 while true:
  print("请输入要翻译的内容,如果退出输入q")
  content = input()
  if (content == 'q'):
   break
  baidu_translate(content)

官方版本：

#/usr/bin/env python
#coding=utf8
 
import httplib
import md5
import urllib
import random
 
appid = '20151113000005349'
secretkey = 'osubcezlgjzvw8qdqc41'
 
 
httpclient = none
myurl = '/api/trans/vip/translate'
q = 'apple'
fromlang = 'en'
tolang = 'zh'
salt = random.randint(32768, 65536)
 
sign = appid+q+str(salt)+secretkey
m1 = md5.new()
m1.update(sign)
sign = m1.hexdigest()
myurl = myurl+'?appid='+appid+'&q='+urllib.quote(q)+'&from='+fromlang+'&to='+tolang+'&salt='+str(salt)+'&sign='+sign
 
try:
 httpclient = httplib.httpconnection('api.fanyi.baidu.com')
 httpclient.request('get', myurl)
 
 #response是httpresponse对象
 response = httpclient.getresponse()
 print response.read()
except exception, e:
 print e
finally:
 if httpclient:
  httpclient.close()
