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) ------------------------------------------------------------------------------

/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

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!!??
