Python获取百度翻译的两种方法

一、引言

百度是我们常用的搜索工具，其翻译是与爱词霸合作，总体看其反应速度较快，可以作为项目中重要的翻译工具。根据大家的需要，现提供两种Python获取百度翻译的两种办法：

二、requests法

我们引用requests模块，向百度发出post请求，得到回复后，进行解释为json格式数据。代码如下：

import requests  #找一个趁手的工具，1. 导入这个工具
url = "https://fanyi.baidu.com/sug"  # 2. 确定爬取的网址，存到变量里面url
#3. 伪装爬虫

while True:word = input("请输入单词：")resp = requests.post(url,headers = headers, data = {"kw":word})  # 发请求for item in resp.json()['data']:#想看效果，就打印Itemprint(item["v"])

三、urllib法

导入urllib，发出Request向url请求，再用urlopen读取并编码为utf-8，最后获取单词的翻译，代码如下：

from urllib import request, parse
import json
def translate_word(string):url = "https://fanyi.baidu.com/sug"  # 请求数据的url链接data = {'kw': string}data_url = parse.urlencode(data)req = request.Request(url=url, data=data_url.encode('utf-8'))response = request.urlopen(req).read()res = json.loads(response)if 'data' in res and len(res['data']) > 0:trans_list = res['data'][0]['v']if ';' in trans_list:trans = trans_list.split(';')else:trans = trans_listelse:trans = "翻译失败"return trans_list
print(translate_word("think"))
