    -sharp define the fields for your item here like:
    -sharp name = scrapy.Field()
    image_urls = scrapy.Field()-sharp
    images = scrapy.Field()

from jiandan import settings

class JiandanPipeline(ImagesPipeline)

    def get_media_requests(self, item, info):
        for image_url in item["image_urls"]:
            print(image_url)
            yield scrapy.Request(image_url)


    def item_completed(self, results, item, info):
        image_paths = [x["path"] for ok, x in results if ok]
        if not image_paths:
            raise DropItem("Item contains no images")
        return item
