一个简单的python爬虫,以豆瓣妹子“http://www.dbmeizi.com/category/2?p= ”为例

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="http://www.mamicode.com/(.+?\.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_listdef 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+=1if __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)

/System/Library/Frameworks/Python.framework/Versions/2.7/bin/python /Users/lsf/PycharmProjects/some_subject/get_doubanmeizi_pic.py
start getting url...
url getted! downloading...
download finish!!!

Process finished with exit code 0

 

运行结果如图:

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!!??
