百度贴吧图片抓取工具（Python）

废话不多说，直接上源码。

import os,urllib,urllib2,re

path='E:/img'     #图片保存路径

url=raw_input('Please input URL:')#贴吧地址

pn=1            #贴吧页码

while 1:

    address=url+'?'+'pn='+str(pn)#当前页地址

    try:

        html=urllib2.urlopen(address).read()#读取当前页html

        print '!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!page%d!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!'%(pn)

    except:

        print 'TTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTT'

        exit(0)

    m=re.findall('http://imgsrc.baidu.com/forum/w%3D580/sign=.*?\.jpg',html)#利用正则表达式分析图片URL

    for i in range(0,len(m)):

        print m[i]

        n=re.search('sign=(.*?)/',m[i])#提取图片URL部分字符串作为文件名

        file_name=n.group(1)+'.jpg'

        file_name=os.path.join(path,file_name)

        try:

            print 'loading...'

            urllib.urlretrieve(m[i],file_name)#下载图片

            print 'this picture down complete.'

        except:

            print 'error'

    pn=pn+1#翻页
