我有一个scrapy来抓取一个网站的问题。我按照scrapy教程学习如何抓取网站，我有兴趣在网站上测试它＆＃39; https://www.leboncoin.fr＆＃39;但蜘蛛不起作用。所以，我试过了：
scrapy shell 'https://www.leboncoin.fr'
但是，我还没有得到该网站的回复。
$ scrapy shell 'https://www.leboncoin.fr'

到rrschmidt：完整的日志已更新，当我运行时
fetch('https:www.leboncoin.fr')
我收到了这个：

那么，我该如何解决呢？
感谢您的回答，

看起来该网站已通过robots.txt限制抓取。通常礼貌地尊重这个愿望。
但如果您真的想要抓取网站，可以通过在settings.py中将ROBOTSTXT_OBEY设置更改为false来更改scrapy的默认行为
ROBOTSTXT_OBEY=False
