我的 Scrapy 代码不起作用，我不知道为什么。我的蜘蛛是在 Reddit 上爬取权力的游戏 subreddit 的测试。

这是我的代码：

import scrapy


class Redditbot2Spider(scrapy.Spider):
    name = 'redditbot2'
    allowed_domains = ['www.reddit.com']
    start_urls = ['https://www.reddit.com/r/gameofthrones/']


def parse(self, response):
    titles = response.selector.xpath('//h2/text()').extract()
    votes = response.selector.xpath('//div[@class="_1rZYMD_4xY3gRcSS3p80D0"]/test()').extract()
    time = response.selector.xpath('//a[@class="_3jOxDPIQ0KaOWpzvSQo-1s"]/text()').extract()
    comments = response.selector.xpath('//span[@class="FHCV02u6Cp2zYL0fhQPsO"])/text()').extract()

    for item in zip(titles, votes, time, comments):
        scraped_info = {
            'title': titles[0],
            'vote': votes[1],
            'time': time[2],
            'comments': comments[3],
        }
        yield scraped_info

这是错误的日志：
