title: Scrapy - crawled (200) and referer : none
body: <p>I'm trying to learn how to use scrapy and python but I'm not an expert at all... very far from here.
  I always have an empty file after crawling this page : <a href="http://www.cdiscount.com/mpv-8732-SATENCO.html" rel="nofollow noreferrer">product of c-discount</a> and I don't understand why...</p>
  <p>Here is my code :</p>
  <pre><code>import scrapy
  
  from cdiscount_test.items import CdiscountTestItem
  
  f = open('items.csv', 'w').close()
  
  class CdiscountsellersspiderSpider(scrapy.Spider):
      name = 'CDiscountSellersSpider'
      allowed_domains = ['cdiscount.com']
      start_urls = ['http://www.cdiscount.com/mpv-8732-SATENCO.html']
  
      def parse(self, response):
          items = CdiscountTestItem()
          name = response.xpath('//div[@class=&quot;shtName&quot;]/div[@class=&quot;shtOver&quot;]/h1[@itemprop=&quot;name&quot;]/text()').extract()
          country = response.xpath('//div[@class=&quot;shtName&quot;]/span[@class=&quot;shTopCExp&quot;]/text()').extract()
  
          items['name_seller'] = ''.join(name).strip()
          items['country_seller'] = ''.join(country).strip()
          pass
  </code></pre>
  <p>And the result I get in the cmd windows :</p>
