1、引入from scrapy.utils.project import get_project_settings

2、利用get_project_settings()读取settings.py中的属性

在middlewares.py文件中读取setting属性

from scrapy.utils.project import get_project_settings

class YourSpider(BaseSpider):

def parse(self, response):

settings = get_project_settings()

print “Your USER_AGENT is:\n%s” % (settings.get(‘USER_AGENT’))

#USER_AGENT 在settings.py中定义好的
