我们经常会在网上搜索井下载图片，然而一张一张地下载就太麻烦了，本案例
就是通过网络爬虫技术， 一次性下载该网站所有的图片并保存 。
网站图片下载并保存
将指定网站的 .jpg 和 .png 格式的图片全部下载井保存在自己本地新建的 images 文件夹中 。
import requests,os
from bs4 import BeautifulSoup
from urllib.request import urlopen url = 'http://www.tooopen.com/img/87.aspx' html = requests.get(url)
html.encoding="utf-8" sp = BeautifulSoup(html.text, 'html.parser')
# 建立images目录保存图片
images_dir="E:\\images\\"
if not os.path.exists(images_dir):
os.mkdir(images_dir)
# 取得所有 <a> 和 <img> 标签
all_links=sp.find_all(['a','img']) for link in all_links:
# 读取 src 和 href 属性内容
src=link.get('src')
href = link.get('href')
attrs=[src,src]
for attr in attrs:
# 读取 .jpg 和 .png 檔
if(attr != None)and(('.jpg' in attr)or('.png' in attr)):
# 设置图片文件完整路径
full_path = attr
filename = full_path.split('/')[-1] # 取得图片名
ext = filename.split('.')[-1] #取得扩展名
filename = filename.split('.')[-2] #取得主文件名
if('jpg' in ext):

else:

# 保存图片
try:

f = open(os.path.join(images_dir,filename),'wb')
f.write(image.read())
f.close()
except:
