本例程使用urlib實現(xiàn)的,基于python2.7版本,采用beautifulsoup進行網(wǎng)頁分析,沒有第三方庫的應該安裝上之后才能運行,我用的IDE是pycharm,閑話少說,直接上代碼!
# -*- coding: utf-8 -*import reimport osimport urllibimport urllib2from bs4 import BeautifulSoupdef craw(url,page): html1=urllib2.urlopen(url).read() html1=str(html1) soup=BeautifulSoup(html1,'lxml') imagelist=soup.select('#J_goodsList > ul > li > div > div.p-img > a > img') namelist=soup.select('#J_goodsList > ul > li > div > div.p-name > a > em') #pricelist=soup.select('#plist > ul > li > div > div.p-price > strong') #print pricelist path = "E:/{}/".format(str(goods)) if not os.path.exists(path): os.mkdir(path) for (imageurl,name) in zip(imagelist,namelist): name=name.get_text() imagename=path + name +".jpg" imgurl="http:"+str(imageurl.get('data-lazy-img')) if imgurl == 'http:None': imgurl = "http:" + str(imageurl.get('src')) try: urllib.urlretrieve(imgurl,filename=imagename) except: continue'''#J_goodsList > ul > li:nth-child(1) > div > div.p-img > a > img#plist > ul > li:nth-child(1) > div > div.p-name.p-name-type3 > a > em#plist > ul > li:nth-child(1) > div > div.p-price > strong:nth-child(1) > i'''if __name__ == "__main__": goods=raw_input('please input the goos you want:') pages=input('please input the pages you want:') count =0.0 for i in range(1,int(pages+1),2): url="https://search.jd.com/Search?keyword={}&enc=utf-8&qrst=1&rt=1&stop=1&vt=2&suggest=1.def.0.T06&wq=diann&page={}".format(str(goods),str(i)) craw(url,i) count += 1 print 'work completed {:.2f}%'.format(count/int(pages)*100)圖片的命名為商品的名稱,京東商品圖片地址的屬性很可能會有所變動,所以大家進行編寫的時候應該舉一反三,靈活運用!
這是我下載下來的手機類圖片文件的截圖:

我本地的爬取的速度很快,不到一分鐘就能爬取100頁上千個商品的圖片!
以上這篇python利用urllib實現(xiàn)爬取京東網(wǎng)站商品圖片的爬蟲實例就是小編分享給大家的全部內(nèi)容了,希望能給大家一個參考,也希望大家多多支持武林站長站。
