由于robots.txt错误，您将被禁止，因此只需将以下行添加到您的

设置.py

USER_AGENT = 'Mozilla/5.0 (Windows NT 5.2; rv:10.0.1) Gecko/20100101 Firefox/10.0.1 SeaMonkey/2.7.1' # any browser specific user agent will do
ROBOTSTXT_OBEY=False

好吧，太棒了-这似乎奏效了！然而，我的程序实际上并没有删除任何我想要的文本名。。2018-05-15 16:27:54[scrapy.core.scraper]调试：从{'program'：[]}中刮取。它只是将其留空，我认为我的蜘蛛css有问题吗？是的，只需删除

之间的
号行

。它应该是

div.title a.action.main.noline:：text
