мне нужна помощь. Я хотел сделать поисковый робот для определенного веб-сайта (underminejournal). Я хочу получить эти данные с сайта, чтобы создать для меня консольный вывод, потому что я в основном работаю на консолях и не хочу так часто переключаться. Другой момент в том, что я хочу поместить данные в базу данных (sql и т. Д. Не проблема). Но почему-то я просто получаю это сообщение, когда пытаюсь запустить сканер, учебник, я думаю, не очень полезен:

Мой паук — это:

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


class JournalSpider(scrapy.Spider):
    name = "journal"
    allowed_domains = ["theunderminejournal.com"]
    start_urls = (
        'theunderminejournal.com/#eu/eredar/item/124442',
    )

    def parse(self, response):
        page = respinse.url.split("/")[-2]
        filename = 'journal-%s.html' % page
        with open(filename, 'wb') as f:
            f.write(response.body)
            self.log('Saved file %s' % filename)
        pass
  

Кто-нибудь знает подсказку?
