Example of how to implement command line Youdao dictionary using python

Preface

Since I have been using the Linux system, the support for dictionaries is particularly poor. For me, a poor English speaker, I always get stuck when reading English documents. I was used to using Youdao Dictionary before. , I feel very good. Although there is a web version, it is not supported for the English web pages of the entire site. Simply implement one yourself, a small tool written in Python to implement Youdao dictionary. The idea is also very simple. Just call Youdao's API directly and parse the returned json.

Only python native libraries are used, supporting python2 and python3.

Sample code

#!/usr/bin/env python
# -*- coding:utf-8 -*-

# API key：273646050
# keyfrom：11pegasus11

import json
import sys

try: # py3
 from urllib.parse import urlparse, quote, urlencode, unquote
 from urllib.request import urlopen
except: # py2
 from urllib import urlencode, quote, unquote
 from urllib2 import urlopen


def fetch(query_str=''):
 query_str = query_str.strip("'").strip('"').strip()
 if not query_str:
 query_str = 'python'

 print(query_str)
 query = {
 'q': query_str
 }
 url = 'http://fanyi.youdao.com/openapi.do?keyfrom=11pegasus11&key=273646050&type=data&doctype=json&version=1.1&' + urlencode(query)
 response = urlopen(url, timeout=3)
 html = response.read().decode('utf-8')
 return html


def parse(html):
 d = json.loads(html)
 try:
 if d.get('errorCode') == 0:
  explains = d.get('basic').get('explains')
  for i in explains:
  print(i)
 else:
  print('无法翻译')

 except:
 print('翻译出错，请输入合法单词')


def main():
 try:
 s = sys.argv[1]
 except IndexError:
 s = 'python'
 parse(fetch(s))


if __name__ == '__main__':
 main()

Use

to paste the above code and name it Modify the name mv youdao.py youdao for youdao.py

, and then add executable permissions chmod a+x youdao

and copy it to /usr/local/bin. cp youdao /usr/local/bin

When using, use the word to be translated as the first command line parameter, and enclose the sentence in quotation marks.
