爬虫入门.

requests爬虫简单框架：

import requests
try:
    r = requests.get(url)
    r.raise_for_status()  #如果状态码不是200会异常
    r.encoding = r.apparent_encoding
    return r.text
except:
    return ‘产生异常

 

 

path=r‘c:/abc.jpg‘
open(path, ‘wb‘)

会报错：PermissionError: [Errno 13] Permission denied: ‘c:/abc.jpg‘

path=r‘c:/1/abc.jpg‘
open(path, ‘wb‘)

就不会。。。不明白

 

path = r‘c:/1/abc.jpg
with open(path, ‘wb‘) as f:
    f.write(r.content)
