本文執行個體講述了Python實現批量下載圖片的方法。分享給大家供大家參考。具體實現方法如下：
#!/usr/bin/env python#-*-coding:utf-8-*-'#Filename:download_file.pyimport os,sysimport reimport urllibimport urllib2base_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'.*?',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_urldef 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 idef urlcallback(a,b,c): """ call back function a,已下載的資料區塊 b,資料區塊的大小 c,遠程檔案的大小 """ 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[:]'''
