python-3.x - Scrapy Python Xpath 和 CSS + splash：返回一个空列表

Question

我想在这个网页上抓取产品的名称，但我得到一个空列表。我将 splash 用于动态网页，但结果是一样的。有人可以告诉我该怎么做吗？任何其他解决方案？

这是我要抓取的网页：https ://www.woolworths.com.au/shop/browse/drinks/cordias-juices-iced-teas/iced-teas

import scrapy

from shop.items import ShopItem

from scrapy_splash import SplashRequest


class Spider(scrapy.Spider) :

      name = 'productsspider'
      start_urls = ['https://www.woolworths.com.au/shop/browse/drinks/cordials-juices-iced-teas/iced-teas']

      def start_requests(self):
          for url in self.start_urls:
          yield SplashRequest(url=url, callback=self.parse, args={"wait":3})

      def parse(self, response):
          item = ShopItem()
          for p in response.css(".divng-tns-c32-15 product-grid.ng-trigger.ng-trigger-staggerFadeInOut"):
              item = productsItem()
              item["product_name"] = p.css(".ng-tns-c32-15.product-grid--tile.ng-star-inserted .ng-tns-c32-15.product-grid--tile.ng-star-inserted shared-product-tile section .shelfProductTile-content div header a::text").extract()
              yield item
