我在抓取网站时遇到了一点问题。我按照scrapy的教程学习了如何抓取网站，我有兴趣在网站' https://www.leboncoin.fr '上测试它，但蜘蛛不起作用。所以，我试过：
scrapy shell 'https://www.leboncoin.fr'
但是，我没有对该网站的回应。
$ scrapy shell 'https://www.leboncoin.fr'

To rrschmidt：完整的日志已更新，当我运行时
fetch('https:www.leboncoin.fr')
我收到这个：
2017-05-16 08:33:15 [scrapy.downloadermiddlewares.robotstxt] DEBUG: Forbidden by robots.txt: <GET https://www.leboncoin.fr>
那么，我该如何解决呢？
谢谢你的回答，
