proxies = {

  "http": "http://124.131.242.155:80"

headers = {'content-type': 'application/json',

           'Accept - Encoding': 'gzip, deflate, sdch'

           }

url = 'http://luoyang.cncn.com/photo/'

r = requests.get(url,headers=headers).text.encode("utf8")

print r

list_url_list = re.findall('data-original="(.*?\.jpg)"', r)

i = 1

for each in list_url_list:

    print "正在下载中 :"+ each

    # 休息10秒钟再去下载

    time.sleep(1)

    pic = requests.get(each, headers=headers)

    # 打印出来是否请求成功，成功后返回状态码 200

    print pic.status_code

    fp = open('pic\\' + str(i) + '.jpg', 'wb')

    fp.write(pic.content)

    fp.close()

    i += 1

    print i

此实例具有时效性，可能过一点时间网站更换主页，可能就不能实现抓取图片，注意在项目中新建 pic文件夹
