【问题描述】：
我正在尝试从此site 中提取出价信息。我是一个 Scrapy 新手，对于为什么我没有得到任何输出感到困惑，相反，我得到了 Crawled (200)...(referer: None) 并且没有输出。我无法弄清楚我缺少什么或需要改变什么。我真的不知道问题出在哪里。谁能帮忙解决一下？
谢谢！！
这是我的蜘蛛代码：
from ..items import GovernmentItem
import scrapy, urllib.parse
class GeorgiaSpider(scrapy.Spider):
name = 'georgia'
allowed_domains = ['ssl.doas.state.ga.us']
def start_requests(self):
url = 'https://ssl.doas.state.ga.us/gpr/'
yield scrapy.Request(url=url, callback=self.parse)
def parse(self, response):
for row in response.xpath('//*[@class="table table-striped table-bordered"]//tbody//tr'):
item = GovernmentItem()
item['description'] = row.xpath('./td[@class=" all"][2]').extract_first()
item['begin_date'] = row.xpath('./td[@class=" desktop"]').extract_first()
item['end_date'] = row.xpath('./td[@class="desktop tablet mobile sorting_1"]').extract_first()
item['file_urls'] = row.xpath('./td[@class=" all]/a//@href').extract_first()
yield item
这是我的爬取日志文件：
