其中用到urllib2模块和正则表达式模块。下面直接上代码：
[/code]
#!/usr/bin/env python
#-*- coding: utf-8 -*-
#通过urllib(2)模块下载网络内容
import urllib,urllib2,gevent
#引入正则表达式模块，时间模块
import re,time
from gevent import monkey
monkey.patch_all()
def geturllist(url):
url_list=[]
print url
s = urllib2.urlopen(url)
text = s.read()
#正则匹配，匹配其中的图片
html = re.search(r'
', text, re.S)
urls = re.finditer(r'jpg)
',html.group(),re.I)
for i in urls:
url=i.group(1).strip()+str("jpg")
url_list.append(url)
return url_list
def download(down_url):
name=str(time.time())[:-3]+"_"+re.sub('.+?/','',down_url)
print name
urllib.urlretrieve(down_url, "D:\\TEMP\\"+name)
def getpageurl():
page_list = []
#进行列表页循环
for page in range(1,700):
url="http://jandan.net/ooxx/page-"+str(page)+"#comments"
#把生成的url加入到page_list中
page_list.append(url)
print page_list
return page_list
if __name__ == '__main__':
jobs = []
pageurl = getpageurl()[::-1]
#进行图片下载
for i in pageurl:
for (downurl) in geturllist(i):
jobs.append(gevent.spawn(download, downurl))
gevent.joinall(jobs)
[/code]
程序不长才45行，不是太难，大家可以研究下，这里我只是抛砖引玉，大家可以根据原理开发出其他的抓取程序，呵呵，自己想去吧。。。我就不多说了~~
