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

 try:
  httpClient = http.client.HTTPConnection('api.fanyi.baidu.com')
  httpClient.request('GET', myurl)
  # response是HTTPResponse对象

  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
