爬虫：代码模拟浏览器向服务器发送请求并得到目标数据。

二、

1.get请求

 1 import requests
 2 
 3 query = input("请输入你想查询的内容：")
 4 url = f"https://www.sogou.com/web?query={query}"
 5 
 6 header = {
 7     "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/60.0.3100.0 Safari/537.36"
 8 }
 9 
10 res = requests.get(url, headers=header)
11 
12 print(res)
13 print(res.request)
14 print(res.encoding)
15 
16 with open('sougou.html', mode="w", encoding='utf-8') as f:
17     f.write(res.text)
18     f.close()

2.post请求

import requests

url = "https://fanyi.baidu.com/sug"

s = input('请输入您想查询的单词:')

da = {
    'kw': s
}

res = requests.post(url, data=da)
res.close()
res = res.json()

print(res['data'][0]['k']+'的中文翻译为为：')
print(res['data'][0]['v'])
