1、抓取煎蛋網上的圖片。

2、代碼如下：

import urllib.requestimport os#to open the urldef url_open(url): req=urllib.request.Request(url) req.add_header('User-Agent','Mozilla/5.0 (Windows NT 6.3; WOW64; rv:51.0) Gecko/20100101 Firefox/51.0') response=urllib.request.urlopen(url) html=response.read() return html#to get the num of page like 1,2,3,4...def get_page(url): html=url_open(url).decode('utf-8') a=html.find('current-comment-page')+23 #add the 23 offset th arrive at the [2356] b=html.find(']',a) #print(html[a:b]) return html[a:b]#find the url of imgs and return the url of arrdef find_imgs(url): html=url_open(url).decode('utf-8') img_addrs=[] a=html.find('img src=') while a!=-1:  b=html.find('.jpg',a,a+255) # if false : return -1  if b!=-1:   img_addrs.append('http:'+html[a+9:b+4])  else:   b=a+9  a=html.find('img src=',b) #print(img_addrs)   return img_addrs  #print('http:'+each)  #save the imgs def save_imgs(folder,img_addrs): for each in img_addrs:  filename=each.split('/')[-1] #get the last member of arr,that is the name  with open(filename,'wb') as f:   img = url_open(each)   f.write(img) def download_mm(folder='mm',pages=10): os.mkdir(folder) os.chdir(folder) url='http://jandan.net/ooxx/' page_num=int(get_page(url))  for i in range(pages):  page_num -= i  page_url = url + 'page-' + str(page_num) + '#comments'  img_addrs=find_imgs(page_url)  save_imgs(folder,img_addrs)  if __name__ == '__main__': download_mm()
