html = response.text

2. 解析网页

selector = parsel.Selector(html)

print(selector)

dir_name = ‘doutu_list’
if not os.path.exists(dir_name):

os.mkdir(dir_name)

result_list = selector.xpath(‘//a[@class=”col-xs-6 col-sm-3″]’)
for result in result_list:

title = result.xpath('./img/@alt').get()
img_url = result.xpath('./img/@data-original').get()
ext = img_url.split('.')[-1]
file_name = title+'.'+ext
print(title,img_url)
# 保留
