本想抓取网易摄影上的图,但发现查看html源代码时找不到图片的url,但firebug却能定位得到。(不知道为什么???)

目标是抓取前50页的爆乳图,代码如下:

import urllib2,urllib,re,os
‘‘‘
http://www.dbmeizi.com/category/2?p=%
‘‘‘
def get_url_from_douban():
    url_list=[]
    p=re.compile(r‘‘‘<img.*?src="(.+?\.jpg)‘‘‘) #找出发布人的标题和url
    for i in range(1,50):
        target = r"http://www.dbmeizi.com/category/2?p=%d"%i
        # print target
        req=urllib2.urlopen(target)
        result=req.read()
        matchs=p.findall(result)
        url_list.extend(matchs)
        # print matchs
        # print "-----"*40
    return url_list
def download_pic(url_list):
    # print url_lists
    count=0
    if not os.path.exists(/tmp/pic):
        os.mkdir(/tmp/pic/)
    for url in url_list:
        urllib.urlretrieve(url,/tmp/pic/+str(count)+.jpg)
        count+=1


if __name__==__main__:
    # start_time=time.time()
    print "start getting url..."
    url_lists=get_url_from_douban()
    print "url getted! downloading..."
    download_pic(url_lists)
    print "download finish!!!"
    # cost_time=time.time() - start_time()
    # print cost_time
    # download_pic(url_lists)

只是一个简单的实现方式,没有考虑性能,速度挺慢的。

ps:贴图会不会被查水表!!??
