又发现一个图集，用python3抓下：

import urllib.request def main(): url='http://cdn.test.com/downloads/character' path='/home/me/Pictures/paper/paper-' for i in range(1,400): ii='' if i<10: ii="00"+str(i) elif i<100: ii="0"+str(i) else: ii=str(i) url=url+ii+".jpg" print (url) h='' try: doc=urllib.request.urlopen(url) h=str(doc.info()) except urllib.error.HTTPError: print(ii+'is not exist') if('jpeg' in h): path=path+ii+".jpg" data = urllib.request.urlopen(url).read() f = open(path,"wb") f.write(data) f.close() path='/home/me/Pictures/paper/paper-' print (str(ii)+"OK") url='http://cdn.test.com/downloads/character' if __name__ == "__main__": main()[/code]

有两点改变，python2 import的是urllib，这里用到urlopen，需要import urllib.request。还有就file已经不用了，换成open就好了。getheader函数也没有了。可以对比下python2版本的另一篇python批量下图。

有个网站图片很好看，网址也很有规律，但是有的是空链接。用python都下下来了。

import urllib
def main():
  url='http://static.host.com/wallpapers/picture-'
  path='/home/me/Pictures/wallpaper/picture-'
  for i in range(0,400):
    url=url+str(i)+".jpg"
    print url
    doc=urllib.urlopen(url)
    type=doc.info().getheader('Content-Type')
    if(type.find('jpeg')!=-1):
      path=path+str(i)+".jpg"
      data=urllib.urlopen(url).read()
      f=file(path,"wb")  
      f.write(data)  
      f.close()
      path='/home/me/Pictures/wallpaper/picture-'
      print str(i)+"OK"
    url='http://static.host.com/wallpapers/picture-'

if __name__ == "__main__":
  main()
