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.
