python - Scrapy 没有在分页之后填充输出

问题描述

我写了一个简单的蜘蛛来提取一些书籍数据，我之前已经这样做了，但现在它不起作用，我无法找出问题所在。我正在使用Python 3.7.

RomHistSpider.py

import scrapy
from romanceshistoricos.items import Livro 

class RomHistSpider(scrapy.Spider):
    name = 'RomHistSpider'
    allowed_domains = ['ebook-romanceshistoricos.blogspot.com']
    start_urls = [
            'https://ebook-romanceshistoricos.blogspot.com/',
            ]

    def parse(self, response):

        livros = response.xpath('//h3/a/@href').extract()
        for livro in livros:
            absolute_url = response.urljoin(livro)
            yield scrapy.Request(absolute_url, callback=self.parse)

        titulo = response.xpath('//div[1]/h3/text()').extract_first()
        serie = response.xpath('//*[@class="post-body entry-content"]/b[1]/text()').extract_first()
        sinopse = ''.join(response.xpath('//*[@id="post-body-8314965505352045179"]/div/b/span/text()').extract())
        tags = response.xpath('//div[1]/div/div/div/div[1]/div[3]/div[2]/span/a/text()').extract()
        endereco = response.url

        item = Livro()
        item['titulo'] = titulo.strip() 
        if serie is not None:
            item['serie'] =  serie.strip() 
        else:
            item['serie'] = 'n/a' 
        item['sinopse'] = sinopse.partition('Capítulo')[0]
        item['tags'] = ', '.join(tags)
        item['url'] = endereco

        return item

        nxt_url = response.xpath(
                '//*[@id="Blog1_blog-pager-older-link"]/@href').extract_first()
        if nxt_url is not None:
            yield response.follow(nxt_url, callback=self.parse)

~scrapy crawl RomHistSpider -o test.csv
