对于一个研究项目，我正在应用一个非常基本的蜘蛛代码，以从Google新闻结果摘要中提取ID元素“ resultStats”（请参见下文）。但是，我通过搜索创建的CSV文件中没有显示结果。
下面的代码是否有任何巧妙的调整，以使其显示分配给'resultStats'的值？
我正在使用Scrapy模块进行此搜索，尽管我阅读了很多声明，BeautifulSoup可能是一个很好的补充。如果更可行，我很乐意考虑使用BS4模块。
import scrapy
class QuotesSpider(scrapy.Spider):
name = 'termcheck'
start_urls = [
'https://www.google.com/search?q=elon+musk&biw=1440&bih=752&source=lnt&tbs=cdr%3A1%2Ccd_min%3A1%2F1%2F2015%2Ccd_max%3A12%2F31%2F2015&tbm=nws',
]
def parse(self, response):
for quote in response.css('div.quote'):
yield {
'resultStats': resultStats.css('span.text::text').get(),
}
next_page = response.css('li.next a::attr("href")').get()
if next_page is not None:
yield response.follow(next_page, self.parse)
下面的运行时日志：
