简单爬虫，通过百度翻译api获取数据

一、导入模块

import urllib.requestimport urllib.parse

二、构造请求头，设置请求参数

• 1.设置url

url = 'http://fanyi.baidu.com/sug'

• 2.在headers中构造user-agent

headers = {'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/63.0.3239.108 Safari/537.36'}

• 3.构造post参数

word = 'wolf'data = {    'kw':word}data = urllib.parse.urlencode(data).encode('utf-8')

三、模拟request请求

request = urllib.request.Request(url=url,headers=headers,data=data)

四、发送请求

response = urllib.request.urlopen(request)

五、输出获取数据

print(response.read().decode('utf-8'))
