本文实例讲述了Python实现批量下载图片的方法。分享给大家供大家参考。具体实现方法如下：
#!/usr/bin/env python #-*-coding:utf-8-*-' #Filename:download_file.py import os,sys import re import urllib import urllib2 base_url = 'xxx' array_url = list() pic_url = list() inner_url = list() def get_array_url(array_url,base_url): content = urllib.urlopen(base_url).read() array_url_a = re.findall(r'/rihan.*?.html',content) for url in array_url_a: url_a = 'xxx'+url #print url_a array_url.append(url_a) def get_inner_url(array_url,inner_url): inner_url.append(array_url) content = urllib.urlopen(array_url[10]).read() content = content.replace(" ","") url_a = re.findall(r'<li>.*?</li>',content) for i in url_a: url = re.findall(r'ahref='.*?.html'target',i) if len(url)>0: # print url[0] url_b = re.sub(r'ahref='','',url[0]) # print url_b url_c = re.sub(r''target','',url_b) url_c = 'http://xxx/'+re.sub(r'/.*/','',url_c) inner_url.append(url_c) del inner_url[1] # print inner_url def get_pic_url(pic_url,inner_url,array_url): content = urllib.urlopen(array_url).read() pic_url_a = re.findall(r'center.*?.jpg',content) print 'bbbbbbbbb',len(pic_url_a) pic_url_a = re.findall(r'http://.*.jpg',pic_url_a[0]) pic_url.append(pic_url_a[0]) j=2 for i in inner_url: jj = '/'+str(j)+'.jpg' pic = re.sub(r'/1.jpg',jj,pic_url_a[0]) pic_url.append(pic) j = j+1 del pic_url[-1] for i in pic_url: print i def urlcallback(a,b,c): """ call back function a,已下载的数据块 b,数据块的大小 c,远程文件的大小 """ print "callback" prec=100.0*a*b/c if 100 < prec: prec=100 print "%.2f%%"%(prec,) def download(img_url,file_num): for img in img_url: print img img_name = re.sub(r'http://.*/','',img) path = 'C:/'+str(file_num)+'/'+img_name urllib.urlretrieve(img,path,urlcallback) get_array_url(array_url,base_url) file_num = 3 #download(pic_url,file_num) get_inner_url(url,inner_url) get_pic_url(pic_url,inner_url,url) ''' for url in array_url: print url # get_inner_url(url,inner_url) # get_pic_url(pic_url,inner_url) get_inner_url(url,inner_url) get_pic_url(pic_url,inner_url,url) download(pic_url,file_num) file_num = file_num+1 del inner_url[:] del pic_url[:] '''
希望本文所述对大家的Python程序设计有所帮助。
