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()
