Scrapy爬取图片只能爬取一张

目标URL为：https://sc.chinaz.com/tupian/

使用Scrapy框架，尝试使用ImagesPipeline

出来的结果是仅爬取到了最后一张：

以下是我的代码：

spider：

import scrapy
from imgPro.items import ImgproItem
from PIL import Image


class ImgSpider(scrapy.Spider):
    name = 'img'
    #allowed_domains = ['www.xxx.com']
    start_urls = ['https://sc.chinaz.com/tupian/']


    def parse(self, response):
        div_list = response.xpath('//*[@id="container"]/div')
        # print(div_list)
        # url = 'https://sc.chinaz.com'

        for div in div_list:
            #使用伪属性 （图片懒加载）
            img_src = 'https:' + div.xpath('./div/a/img/@src2')[0].extract()
            print(img_src)

        item = ImgproItem()
        item['src'] = img_src

        #提交item到管道
        yield item

items：

import scrapy


class ImgproItem(scrapy.Item):
    # define the fields for your item here like:
    src = scrapy.Field()

    pass

pipelines：

import scrapy

from scrapy.pipelines.images import ImagesPipeline

class imagePipeLine(ImagesPipeline):

    #该方法可以基于图片地址进行图片请求
    def get_media_requests(self, item, info):
       yield scrapy.Request(item['src'])

    #该方法指定图片存储路径
    def file_path(self, request, response=None, info=None, *, item=None):
        imag_name = request.url.split('/')[-1]
        return imag_name

    #将item返回给下一个需要执行的管道类
    def item_completed(self, results, item, info):
        return item

我能说的是 找规律
