Python和Scrapy-Scraper不返回结果

Question

您好，在此感谢您为我提供的任何帮助。我以前从未发布过编码方面的帮助，并且对编程还很陌生。自学成才的老人正在尝试学习新事物，也许建造一些东西来拯救世界（或者只是建造一些东西。

我已经抓狂了，当我运行终端命令“ scrapy crawl coops”时，我总是得到DEBUG：Crawled（200），并且看不到任何“ Found details：”条目。我能够运行scrapy shell“ http://coopdirectory.org/directory.htm”并通过shell手动获得结果。当我尝试屈服为.jl或.js文件时，它们也为空。 （我用草率的教程引号使这项工作很棒）。下面是我的代码，下面是结果。任何方向都很好。

import scrapy


class CoopsSpider(scrapy.Spider):
    name = "coops"
    start_urls = [
    'http://coopdirectory.org/directory.htm',
    ]

    def parse(self, response):
        for coop in response.css('div.coop'):
            yield {
                'name': coop.css('h3 a::text').getall(),
                'address': coop.css('.address::text').getall(),
                'website': coop.css('.web-address::text').getall(),
                'phone': coop.css('.phone::text').getall(),
                'org_type': coop.css('.org-type::text').getall(),
                'inactive': coop.css('.inactive-alert::text').getall(),
                'notes': coop.css('.note::text').getall(),
            }
结果

您好，在此感谢您为我提供的任何帮助。我以前从未发布过编码方面的帮助，并且对编程还很陌生。自学成才的老人正在尝试学习...

您的CSS选择器（'div.coop'）未选择任何内容，因此在循环内无法产生任何结果。您可以通过打开刮擦的外壳（scrapy shell "http://coopdirectory.org/directory.htm"），然后键入response.css('div.coop')来进行测试。您会看到将返回一个空选择（[]）。
