proxies = {

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
