import scrapy from ..items import ReatutorialItem class ReaspiderSpider(scrapy.Spider): name = 'REAspider' page_number = 2 start_urls = ['website/page1'] def parse(self, response): urls = response.xpath("//li/a[@class='csweblead']/@href").extract() for url in urls: url = response.urljoin(url) yield scrapy.Request(url=url, callback=self.parse) items = ReatutorialItem() name = response.css('.BlueBold14-1::text').extract() price = response.css('.cslistinglead::text').extract() rating= response.css('.bodytext:nth-child(3)::text').extract() items ['name'] = name items ['price'] = price items ['rating'] = rating yield items next_page ='website'+ str(ReaspiderSpider.page_number) +'website' if ReaspiderSpider.page_number <= 7: ReaspiderSpider.page_number +=1 yield response.follow (next_page, callback = self.parse)
