然后我们来看程序操作，代码如下：

#!/usr/bin/python import os import sys import urllib2 import re def Cdown_data(fileurl, fpath, dpath): if not os.path.exists(dpath): os.makedirs(dpath) try: getfile = urllib2.urlopen(fileurl) data = getfile.read() f = open(fpath, 'w') f.write(data) f.close() except: print with open('u1.list') as lines: for line in lines: URI = line.strip() if '?' and '%' in URI: continue elif URI.count('/') == 2: continue elif URI.count('/') > 2: #print URI,URI.count('/') try: dirpath = URI.rpartition('/')[0].split('//')[1] #filepath = URI.split('//')[1].split('/')[1] filepath = URI.split('//')[1] if filepath: print URI,filepath,dirpath Cdown_data(URI, filepath, dirpath) except: print URI,'error'
