python - Scrapy shell 工作正常，但在爬虫上显示 404

Question

设置

我正在尝试用 Scrapy抓取此页面。

在scrapy shell中，我200使用USER_AGENT在页面上得到正确的，即

scrapy shell -s USER_AGENT='Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/55.0.2883.95 Safari/537.36' 'https://www.seloger.com/list.htm?abslc=new&enterprise=0&natures=1,2,4&places=[{cp:77}]&projects=2,5&qsversion=1.0&types=1,2&bd=DetailToList_SL&abSLC=new'

---

问题

在我的实际脚本中，使用相同的 USER_AGENT，Scrapy 得到 404，

我已经ROBOTSTXT_OBEY = False在settings.py.

我可以解决这个问题吗？如果可以，我该怎么做？
