【转】网络翻译实现

原理：利用有道翻译api，提交要查询的单词，返回json结果，然后对结果进行解析输出。

代码在Win7中文系统，Py2.7.3调试通过，有道翻译的key要自己申请：
# -*- coding: cp936 -*-

import urllib

import json

kf = 'xxxx'  #申请的keyfrom
k = 'xxxxxxxxxx'#申请的API key

def dealjson(ret):

    ret = json.loads(ret)

    error = ret['errorCode']

    print error

    if error == 20:

        print '要翻译的文本过长'

    elif error == 30:

        print '无法进行有效的翻译'

    elif error == 40:

        print '不支持的语言类型'

    elif error == 50:

        print '无效的key'

    elif error == 0:

        trans = ret['translation']

        for i in trans:

            print i

        print ret['query']

        if 'basic' in ret.keys():

            explain =  ret['basic']['explains']

            for i in explain:

                print i

                web =ret['web']

                for i in web:

                    print i['key'],

                    for j in i['value']:

                        print j,

                    print



if __name__=='__main__':

    while True:
        kf = 'xxx'
        k = 'xxxx'
        word = raw_input('输入英语单词: ')

        if word == '':

            continue

        word = urllib.quote(word)

        print word

        url = 'http://fanyi.youdao.com/openapi.do?keyfrom='+ kf +'&key=' + k + '&type=data&doctype=json&version=1.1&q='+word

        ret = urllib.urlopen(url).read()
        dealjson(ret)
