CrawlSpider无法正常工作

Question

我是scrapy的新手，我在使用此代码时遇到了问题，而不是通过链接进行解析。

import sys
sys.path.append(r'C:\Users\User\Miniconda3\Lib\site-packages')

import scrapy
from scrapy.spiders import CrawlSpider, Rule
from scrapy.linkextractors import LinkExtractor

class MySpider(CrawlSpider):
    name = 'poder360.com'
    allowed_domais = ['poder360.com.br']
    start_urls = ['https://www.poder360.com.br']

    rules = (Rule(LinkExtractor(allow_domains=['poder360.com.br']),
        callback='parse_item', follow=True))

    def parse_item(self, response):
        self.logger.info('Hi, this is an item page! %s', response.url)
        item = scrapy.Item()
        item['title'] = response.xpath('//title/text()').extract()
        print(item['title'])
        return item
