Я очень плохо знаком с scrapy, пока выполняю код, получаю эту ошибку.
Мой код
import urlparse
from scrapy.http import Request
from scrapy.spiders import BaseSpider
class legco(BaseSpider):
name = "sec_gov"
allowed_domains = ["www.sec.gov", "search.usa.gov", "secsearch.sec.gov"]
start_urls = ["https://www.sec.gov/cgi-bin/browse-edgar?company=&match=&CIK=&filenum=&State=&Country=&SIC=2834&owner=exclude&Find=Find+Companies&action=getcompany"]
#extract home page search results
def parse(self, response):
for link in response.xpath('//div[@id="seriesDiv"]//table[@class="tableFile2"]/a/@href').extract():
req = Request(url = link, callback = self.parse_page)
print link
yield req
#extract second link search results
def parse_second(self, response):
for link in response.xpath('//div[@id="seriesDiv"]//table[@class="tableFile2"]//*[@id="documentsbutton"]/a/@href').extract():
req = Request(url = link, callback = self.parse_page)
print link
yield req
Однажды я попытался запустить этот код: scrapy crawl sec_gov получаю эту ошибку.
