Scrapy Crawling 0 pages

Question

pythonとscrapyには、何がコードに間違っていますか？私はscrapyシェルからデータを取得できますが、なぜscrapyのクロールでは取得できませんか？

編集：私は下のログを入れました、あなたは私がどのような問題をチェックするのを助けることができますか？

問題は解決：
このリンクは、誤った価格= 2-2/
あるべき価格= 2-2

quotes.spider.py

import scrapy 
from tutorial.items import TutorialItem 

class QuotesSpider(scrapy.Spider): 
    name = "quotes" 

def start_requests(self): 
    urls = [ 
     'http://www.testing.com.my/?price=2-2/', 
    ] 
    for url in urls: 
     yield scrapy.Request(url=url, callback=self.parse) 

def parse(self, response): 
    titles = response.xpath('//a[contains(@class, "c-product-card__img-placeholder-inner")]/@href') 
    return titles.extract() 

アイテムです？ .py

from scrapy.item import Item, Field 

class TutorialItem(Item): 
    link = Field()

Answer 1

あなたは、各記事のリンクを抽出したい場合は、私のようなものを提案したい：

response.css("a.c-product-card::attr(href)") 

の代わり：

response.xpath('//a[contains(@class, "c-product-card__img-placeholder-inner")]/@href')
