python3调用百度翻译接口样例

baidu开放的翻译接口http://api.fanyi.baidu.com/api/trans/product/apidoc支持每月200万字的免费翻译，提供了各种语言的使用demo。python语言的demo是2版本的，稍作修改在python3跑了下，并将结果写入文件中。这样可以获得一些中英翻译的语料，进行翻译，分类等很多自然语言的任务。

#coding=utf-8import http.clientimport hashlibfrom urllib import parseimport randomappid = '注册的id'secretKey = '注册获得的key'httpClient = Nonemyurl = '/api/trans/vip/translate'q = '苹果是一家很棒的公司\n我爱北京天安门'fromLang = 'zh'toLang = 'en'salt = random.randint(32768, 65536)sign = appid+q+str(salt)+secretKeym1 = hashlib.md5()m1.update(sign.encode(encoding='utf-8'))sign = m1.hexdigest()myurl = myurl+'?appid='+appid+'&q='+parse.quote(q)+'&from='+fromLang+'&to='+toLang+'&salt='+str(salt)+'&sign='+sign file = open('result.txt','w')try:    httpClient = http.client.HTTPConnection('api.fanyi.baidu.com')    httpClient.request('GET', myurl)    response = httpClient.getresponse()    str = response.read().decode('utf-8')    str = eval(str)    for line in str['trans_result']:        file.write(line['dst']+'\n')except Exception as e:    print(e)finally:    if httpClient:        httpClient.close()file.close()

翻译结果：
