设置
我正在尝试用Scrapy抓取this page。
在草率的shell中，我使用USER_AGENT在网页上获得了正确的200，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得到了404，

我已经在ROBOTSTXT_OBEY = False中尝试过settings.py。
我可以解决这个问题吗？如果可以，怎么办？
