我想從版權政府網站使用scrapy獲取數據。這是我的蜘蛛:如何獲得scrapy FormRequest的工作

from scrapy.spider import BaseSpider 
from scrapy.selector import HtmlXPathSelector 
from scrapy.http import FormRequest, Request 
from scrapy.utils.response import open_in_browser 

class CopyrightSpider(BaseSpider): 
     name = "copyright_records" 
     start_url = ["http://cocatalog.loc.gov/cgi-bin/Pwebrecon.cgi?DB=local&PAGE=First"] 

     def parse(self, response): 
       yield FormRequest.from_response(response, 
               formname='querybox', 
               formdata={'Search_Arg': 'walt disney', 'Search_Code': 'Command Keyword'}, 
               callback=self.parse1) 

     def parse1(self, response): 

      open_in_browser(response) 

運行履帶然而,當我看到0的頁面被抓取我不明白的錯誤:

這只是一個錯字。

替換:

start_url = ["http://cocatalog.loc.gov/cgi-bin/Pwebrecon.cgi?DB=local&PAGE=First"] 

有:

start_urls = ["http://cocatalog.loc.gov/cgi-bin/Pwebrecon.cgi?DB=local&PAGE=First"]
