一、urllib

import urllib.request

response= urllib.request.urlopen("")

print(html)

 

utf-8解码

html = html.decode("utf-8")

print(html)

二、实战一 下载一只猫

import urllib.request

response = urllib.request.urlopen('http://placekitten.com/g/600/700')
#=req=urllib.request.Request('http://placekitten.com/g/600/700')
#response=urllib.request.urlopen(req)
cat_img = response.read()

with open('cat_600_700.jpg','wb')as f:
f.write(cat_img)

 

三个查询函数. geturl()  info()  getcode()

>>> response.geturl()
'http://placekitten.com/g/600/700'
>>> response.info()
<http.client.HTTPMessage object at 0x0000027B8D8FC898>
>>> print(response.info())

>>> response.getcode()
200
>>>
