Python实现简单的获取图片爬虫功能示例

#coding=utf-8
import urllib
import re
def getHtml(url):
  page = urllib.urlopen(url)
  html = page.read()
  return html
def getImg(html):
  reg = r'src="(.+?\.jpg)" pic_ext'
  imgre = re.compile(reg)
  imglist = re.findall(imgre, html)
  return imglist
// 网站地址
url = "http://tieba.baidu.com/p/3368048910?pn=2"
html = getHtml(url)
listimg = getImg(html)
x = 0
for imgAddress in listimg:
  print imgAddress
  urllib.urlretrieve(imgAddress, 'image%s.jpg' % x)
  x+=1
