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''' @Author: LCY @Contact: lchuanyong@126.com @blog: http://http://blog.csdn.net/lcyong_ @Date: 2018-01-15 @Time: 19:19 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 官方链接： http://api.fanyi.baidu.com/api/trans/product/index ''' import http.clientimport hashlibimport jsonimport urllibimport 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 httplibimport md5import urllibimport random appid = '20151113000005349'secretKey = 'osubCEzlGjzvw8qdQc41' httpClient = Nonemyurl = '/api/trans/vip/translate'q = 'apple'fromLang = 'en'toLang = 'zh'salt = random.randint(32768, 65536) sign = appid+q+str(salt)+secretKeym1 = 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 efinally: if httpClient: httpClient.close()

以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持。
