python scrapy cssセレクタ名抽出が機能しない

Question

CSSセレクタを使用してhttp://www.bschool.careers360.com/search/all/bangaloreから大学名を抽出しようとしていますが、データが抽出されません。 "ROBOTSTXT_OBEY = False"が設定されています。変更後、私のコードは以下の通りです。が、結果は同じ

import scrapy 

class BloreSpider(scrapy.Spider): 
    name = 'blore' 
    start_urls = ['http://www.engineering.careers360.com/search/college/bangalore'] 

    def parse(self, response): 
     for quote in response.css('div.title'): 
      yield { 
       'author': quote.xpath('.//a/text()').extract_first(), 
      } 

     next_page = response.css('li.pager-next a::attr("href")').extract_first() 
     if next_page: 
      next_page = response.urljoin(next_page) 
      yield scrapy.Request(next_page, callback=self.parse) 

をままで、ログが

Answer 1

あなたのxpathがあなたのquoteノードは、他の言葉であなたが//前.を追加する必要があり、あなたの相対的であることが必要です。

これを試してみてください：

def parse(self, response): 
    for quote in response.css('div.title'): 
     yield { 
      #'author': quote.xpath('//a/text()').extract_first(), 
      #      ^
      'author': quote.xpath('.//a/text()').extract_first(), 
     } 

    next_page = response.css('li.pager-next a::attr("href")').extract_first() 
    # if next_page is not None: 
    if next_page: # you can also just do this 
     next_page = response.urljoin(next_page) 
     yield scrapy.Request(next_page, callback=self.parse) 

編集：あなたの提供、ログを見ては、robots.txtのを取得しようとしたとき、あなたが404を得るように思えます。試しましたが、ROBOTS_TXT_OBEY = Falseをsettings.py
