简单访问有道词典的翻译界面，将页面翻译功能简单呈现

import urllib.request
import urllib.parse
import jsoncontent = input("请输入需要翻译的内容：")
url= 'http://fanyi.youdao.com/translate?smartresult=dict&smartresult=rule&smartresult=ugc&sessionFrom=dict2.index'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_ENTER'
data['typoResult']='true'data= urllib.parse.urlencode(data).encode('utf-8')
response = urllib.request.urlopen(url,data)
html = response.read().decode('utf-8')
print (html)target = json.loads(html)
print("翻译结果： %s" %(target['translateResult'][0][0]['tgt']))

结果如下：

请输入需要翻译的内容：长城{"type":"ZH_CN2EN","errorCode":0,"elapsedTime":1,"translateResult":[[{"src":"长城","tgt":"The Great Wall"}]],"smartResult":{"type":1,"entries":["","The Great Wall"]}}翻译结果： The Great Wall
>>> ================================ RESTART ================================
>>>
请输入需要翻译的内容：English{"type":"EN2ZH_CN","errorCode":0,"elapsedTime":1,"translateResult":[[{"src":"English","tgt":"英语"}]],"smartResult":{"type":1,"entries":["","n. 英语；英国人；英文；英格兰人","adj. 英国人的；英国的；英文的","vt. 把\u2026译成英语"]}}翻译结果： 英语

增加request header文件

有两种方法:

• Request的headers参数修改
• Request.add_header()方法修改

import urllib.request
import urllib.parse
import jsoncontent = input("请输入需要翻译的内容：")
url= 'http://fanyi.youdao.com/translate?smartresult=dict&smartresult=rule&smartresult=ugc&sessionFrom=dict2.index'head={}
head['User-Agent']='Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.75 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_ENTER'
data['typoResult']='true'data= urllib.parse.urlencode(data).encode('utf-8')req = urllib.request.Request(url,data,head)
'''
req.add_header('User-Agent','Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.75 Safari/537.36')
'''
response = urllib.request.urlopen(req)
html = response.read().decode('utf-8')
print (html)target = json.loads(html)
print("翻译结果： %s" %(target['translateResult'][0][0]['tgt']))

结果如下：

请输入需要翻译的内容：明月{"type":"ZH_CN2EN","errorCode":0,"elapsedTime":8,"translateResult":[[{"src":"明月","tgt":"The bright moon"}]],"smartResult":{"type":1,"entries":["","bright moon"]}}翻译结果： The bright moon

增加time.sleep

import urllib.request
import urllib.parse
import json
import timewhile True:content = input('请输入需要翻译的内容（输入"q!"退出程序）：')if content == 'q!':breakurl= 'http://fanyi.youdao.com/translate?smartresult=dict&smartresult=rule&smartresult=ugc&sessionFrom=dict2.index'head={}head['User-Agent']='Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.75 Safari/537.36'data = {}data['type']='AUTO'data['i']= contentdata['doctype']='json'data['xmlVersion']='1.8'data['keyfrom']='fanyi.web'data['ue']='UTF-8'data['action']='FY_BY_ENTER'data['typoResult']='true'data= urllib.parse.urlencode(data).encode('utf-8')req = urllib.request.Request(url,data,head)'''req.add_header('User-Agent','Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.75 Safari/537.36')'''response = urllib.request.urlopen(req)html = response.read().decode('utf-8')print (html)target = json.loads(html)print("翻译结果： %s" %(target['translateResult'][0][0]['tgt']))time.sleep(5)

结果是执行完每一次程序后暂停5秒，再执行下一次：

请输入需要翻译的内容（输入"q!"退出程序）：皮卡丘{"type":"ZH_CN2EN","errorCode":0,"elapsedTime":1,"translateResult":[[{"src":"皮卡丘","tgt":"Pikachu"}]],"smartResult":{"type":1,"entries":["","Pikachu"]}}翻译结果： Pikachu
请输入需要翻译的内容（输入"q!"退出程序）：盗墓笔记{"type":"ZH_CN2EN","errorCode":0,"elapsedTime":1,"translateResult":[[{"src":"盗墓笔记","tgt":"Grave notes"}]],"smartResult":{"type":1,"entries":["","Time Raiders"]}}翻译结果： Grave notes
请输入需要翻译的内容（输入"q!"退出程序）：
