title: How get the spider return data with scrapy through an external script?
body: <p>What is the way to view the return data of the parse function of the spider when I execute a script like this?</p>
  
  <pre><code>from twisted.internet import reactor
  from scrapy.crawler import Crawler
  from scrapy.settings import Settings
  from scrapy import log, signals
  from testspiders.spiders.followall import FollowAllSpider
  
  spider = FollowAllSpider(domain='scrapinghub.com')
  crawler = Crawler(Settings())
  crawler.signals.connect(reactor.stop, signal=signals.spider_closed)
  crawler.configure()
  crawler.crawl(spider)
  crawler.start()
  crawler.stats
  #log.start()
  reactor.run()
  </code></pre>
  
  <p>I disable the log for view the print messages in the spiders, but with the log enabled the return data don't show either.</p>
  
  <p>The code of the spider parse function return a simple string.</p>
  
  <p>How i get this data? I try to print the "reactor.run" results but always is "none"</p>
