概述
花瓣图片的加载使用了延迟加载的技术，源代码只能下载20多张图片，修改后基本能下载所有的了，只是速度有点慢，后面再优化下
import urllib,urllib2,re,sys,os,requests path=r"C:\wqa\beautify" url = 'http://huaban.com/favorite/beauty' #http://huaban.com/explore/zhongwenlogo/?ig1un9tq&max=327773629&limit=20&wfl=1 i_headers = {"User-Agent": "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML,like Gecko) Chrome/46.0.2490.71 Safari/537.36"} count=0 def urlHandle(url): req = urllib2.Request(url,headers=i_headers) html = urllib2.urlopen(req).read() reg = re.compile(r'"pin_id":(\d+),.+?"file":{"farm":"farm1","bucket":"hbimg",.+?"key":"(.*?)",.+?"type":"image/(.*?)"',re.S) groups = re.findall(reg,html) return groups def imgHandle(groups): if groups: for att in groups: pin_id = att[0] att_url = att[1] + '_fw236' img_type = att[2] img_url = 'http://img.hb.aicdn.com/' + att_url r = requests.get(img_url) with open(path + att_url + '.' + img_type,'wb') as fd: for chunk in r.iter_content(): fd.write(chunk) groups = urlHandle(url) imgHandle(groups) while(groups): count+=1 print count pin_id = groups[-1][0] print pin_id urltemp = url+'/?max=' + str(pin_id) + '&limit=' + str(20) + '&wfl=1' print(urltemp) groups = urlHandle(urltemp) #print groups imgHandle(groups)
