yield scrapy.Request() not working properly for crawling next page

Question

The same code works for the different site but not with this one!

site = http://quotes.toscrape.com/

It doesn't give any error and successfully craws 8 pages (or count pages) import scrapy

    count = 8

    class QuotesSpiderSpider(scrapy.Spider):
        name = 'quotes_spider'
        allowed_domains = ['quotes.toscrape.com']
        start_urls = ['http://quotes.toscrape.com/']

        def parse(self, response):
            quotes = response.xpath('//*[@class="quote"]')

            for quote in quotes:
                text = quote.xpath('.//*[@class="text"]/text()').extract_first()
                author = quote.xpath('.//*[@class="author"]/text()').extract_first()

                yield{
                    'Text' : text,
                    'Author' : author
                }

            global count
            count = count - 1
            if(count > 0):
                next_page = response.xpath('//*[@class="next"]/a/@href').extract_first()
                absolute_next_page = response.urljoin(next_page)
                yield scrapy.Request(absolute_next_page)

But it crawls only 1st page for this site

site https://www.goodreads.com/list/show/7

# -*- coding: utf-8 -*-
import scrapy

count = 5

class BooksSpider(scrapy.Spider):
    name = 'books'
    allowed_domains = ["goodreads.com/list/show/7"]
    start_urls = ["https://goodreads.com/list/show/7/"]

    def parse(self, response):
        books = response.xpath('//tr/td[3]')

        for book in books:
            bookTitle = book.xpath('.//*[@class="bookTitle"]/span/text()').extract_first()
            authorName = book.xpath('.//*[@class="authorName"]/span/text()').extract_first()

            yield{
                'BookTitle' : bookTitle,
                'AuthorName' : authorName
            }

        global count
        count = count - 1

        if (count > 0):
            next_page_url = response.xpath('//*[@class="pagination"]/a[@class="next_page"]/@href').extract_first()
            absolute_next_page_url = response.urljoin(next_page_url)
            yield scrapy.Request(url = absolute_next_page_url)

I want to crawl certain limited pages or all pages of 2nd site.

Answer 1

You are using a domain with path in allowed_domains .

allowed_domains = ["goodreads.com/list/show/7"]

should be

allowed_domains = ["goodreads.com"]
