python - 使用 scrapy 在 Stack Overflow 中进行网页抓取，但我无法获得该问题的投票

Question

我正在抓取 Stack Overflow，我已经捕获了标题、URL 和标签，但我无法捕获每个问题的投票。有人能帮我吗？我不太擅长 xpath

def parse_item(self, response):
    questions = response.xpath('//div[@class="question-summary"]')

    for question in questions:
        item = StackItem()
        item['url'] = question.xpath(
            'div[@class="summary"]/h3/a[@class="question-hyperlink"]/@href').extract()[0]
        item['title'] = question.xpath(
            'div[@class="summary"]/h3/a[@class="question-hyperlink"]/text()').extract()[0]
        item['tags'] = question.xpath(
            'div[@class="summary"]/div[2]/a[@class="post-tag"]/text()').extract()
        item['votes'] = question.xpath(
            '/div[1]/div[1]/div[1]/div[1]/span/strong/textContent()').extract()[0]

        yield item

我正在抓取页面: https://stackoverflow.com/questions?page=2&sort=newest

怎么样

item['votes'] = question.css('.vote-count-post > strong::text').extract()[0]

？
