我正在尝试抓取＃页数据。我已经做过一个可以从单个＃页面上抓取数据的抓取工具。但是在刮掉首页之后，它突然完成了工作

具有解析功能和剪贴功能的整个文件-Scraper.py

class Proddduct(scrapy.Item):
    price = scrapy.Field()
    description = scrapy.Field()
    link = scrapy.Field()
    content = scrapy.Field()


class LapadaScraperSpider(scrapy.Spider):
    name = 'lapada_scraper2'

    def parse(self,response):

        for item in self.scrape(response):
            yield item

        if next_page_url:
            print("Found url: {}".format(next_page_url))
            yield scrapy.Request(url=next_page_url,callback=self.parse)

    def scrape(self,response):
        parser = scrapy.Selector(response)

        products = parser.xpath("//div[@class='content']")

        for product in products:
            item = Proddduct()
            XPATH_PRODUCT_DESCRIPTION  = ".//strong/text()"
            XPATH_PRODUCT_PRICE  = ".//div[@class='price']/text()"
            XPATH_PRODUCT_LINK = ".//a/@href"

            raw_product_description = product.xpath(XPATH_PRODUCT_DESCRIPTION).extract()
            raw_product_price = product.xpath(XPATH_PRODUCT_PRICE).extract()
            raw_product_link = product.xpath(XPATH_PRODUCT_LINK).extract_first()

            item['description'] = raw_product_description
            item['price'] = raw_product_price
            item['link'] = raw_product_link

            yield item

    def get_information(self,response):
        item = response.meta['item'] 
        item['phonenumber'] = "12345"
        yield item

如何在所有页面中抓取所有物品？

谢谢
