本文实例讲述了Python爬虫实现简单的爬取有道翻译功能。分享给大家供大家参考，具体如下：
# -*- coding:utf-8 -*-
#!python3
import urllib.request
import urllib.parse
import json
while True :
content = input("请输入需要翻译的内容:(按q退出)")
if content == 'q' :
break
url = 'http://fanyi.youdao.com/translate?smartresult=dict&smartresult=rule&smartresult=ugc&sessionFrom=https://www.baidu.com/link'
head = {}
head[ 'User-Agent'] = 'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/53.0.2785.143 Safari/537.36'
data = {}
data['type'] = 'AUTO'
data['i'] = content
data['doctype'] = 'json'
data['xmlVersion'] = '1.8'
data['keyfrom'] = 'fanyi.web'
data['ue'] = 'UTF-8'
data['action'] = 'FY_BY_CLICKBUTTON'
data['typoResult'] = 'true'
data = urllib.parse.urlencode(data).encode('utf-8')
req = urllib.request.Request(url,data,head)
response = urllib.request.urlopen(req)
html = response.read().decode('utf-8')
target = json.loads(html)
print("翻译结果：%s" %(target['translateResult'][0][0]['tgt']))
