Get spider name in scrapy feed exporter

Question

是否可以在Feed导出器中访问当前蜘蛛的名称？

Answer 1

The doc about storage URI parameters might help.

Or, if you are building your own: The methods used by exporters support passing the spider object to it. For example:

def open_spider(self, spider):
   print spider.name

def close_spider(self, spider):
   print spider.name

def item_scraped(self, item, spider):
   print spider.name
