python实现简单的爬取网页图片

先创建一个image文件

代码如下；举例：爬取sina网址的图片

import re
import chardet
import requests
import  chardet
url = "https://www.sina.com.cn"
response = requests.get(url=url)
charset = chardet.detect(response.content).get('encoding')
response.encoding = charset
html = response.text
images = re.findall(r"src=\"(.*?jpg|png|jepg)\"", html)
for index,item, in enumerate(images):
    if not item.startswith("http"):
        real_url = "http:"+item
        print("开始从{}下载图片".format(real_url))
        resp = requests.get(real_url)
        with open("image/"+str(index)+".jpg","wb") as f:
            f.write(resp.content)

结果如下：
