我怎样才能用Scrapy刮下几页

Question

这是我的刮擦代码。我不知道我的错误，但只在第一页刮擦。我如何刮擦和遍历页面？有没有其他方法可以刮取下一页

import scrapy

class HurriyetEmlakPage(scrapy.Spider):
    
    name = 'hurriyetspider'
    allowed_domain = 'hurriyetemlak.com'
    start_urls = ['https://www.hurriyetemlak.com/satilik']
    
    def parse(self, response):
       
       fiyat = response.xpath('//div[@class="list-view-price"]//text()').extract()
       durum = response.xpath('//div[@class="middle sibling"]//div[@class="left"]//text()').extract()
       oda_sayisi = response.xpath('//span[@class="celly houseRoomCount"]//text()').extract()
       metrekare = response.xpath('//span[@class="celly squareMeter list-view-size"]//text()').extract()
       bina_yasi = response.xpath('//span[@class="celly buildingAge"]//text()').extract()
       bulundugu_kat = response.xpath('//span[@class="celly floortype"]//text()').extract()
       konum = response.xpath('//div[@class="list-view-location"]//text()').extract()

       scraped_info = {
            'fiyat':fiyat,
            'durum': durum,
            'oda_sayisi' : oda_sayisi,
            'metrekare' : metrekare,
            'bina_yasi' : bina_yasi,
            'bulundugu_kat': bulundugu_kat,
            'konum' : konum
        }
       yield scraped_info
       next_page_url = response.xpath('//li[@class="next-li pagi-nav"]//a').extract_first()
       if next_page_url:
            next_page_url = response.urljoin(next_page_url)
            yield scrapy.Request(url = next_page_url,callback = self.parse)

Answer 1

实际上，您只需生成如下url列表：

url_list = [f"https://www.hurriyetemlak.com/satilik?page={page}" for page in range(1,7326)]

输出

['https://www.hurriyetemlak.com/satilik?page=1',
 'https://www.hurriyetemlak.com/satilik?page=2',
 'https://www.hurriyetemlak.com/satilik?page=3',
 'https://www.hurriyetemlak.com/satilik?page=4',
 'https://www.hurriyetemlak.com/satilik?page=5',
