自己写了玩的一个小脚本，百度图片下载

import reimport osimport requestsimport hashlib  def dowmloadPic(html, keyword):  pic_url = re.findall('"objURL":"(.*?)",', html, re.S)   if len(pic_url) < 1:    return 1   i = 0  for each in pic_url:    print(i + 1, end=',')    md5Str = hashlib.md5(each.encode("utf-8")).hexdigest()     # 抓去链接    oneStr = md5Str + '  ' + keyword + '  ' + each + '\n'    with open('downText.txt', 'a+') as f:      f.write(oneStr)     # 下载图片    # try:    #   pic = requests.get(each, timeout=10)    # except requests.exceptions.ConnectionError:    #   print('链接超时,跳过此操作')    #   continue    #    # kz = os.path.splitext(each)[-1]    # photo = + keyword + '_' + str(i) + kz    #    # with open(photo, 'wb') as f:    #   f.write(pic.content)    i += 1   print('\n')  return 0  if __name__ == '__main__':   word = input('enter a key word:')  page = input('enter the page:')   page = int(page)  page = 1 if page < 1 else page   url = 'http://image.baidu.com/search/flip?tn=baiduimage&ie=utf-8&word=' + word + '&ct=201965323&v=flip'   p = 1  while (p <= page):    print(word + ',第[' + str(p) + ']页：')     pn = (p - 1) * 20    url = url + '&pn=' + str(pn)    result = requests.get(url).content.decode('utf-8')     code = dowmloadPic(result, word)     if code:      print('无相关数据,提前退出程序')      break    p = p + 1   print('程序结束')
