scrapy: Call a function when a spider quits

Question

Is there a way to trigger a method in a Spider class just before it terminates?

I can terminate the spider myself, like this:

class MySpider(CrawlS         


        

Answer 1

For me the accepted did not work / is outdated at least for scrapy 0.19. I got it to work with the following though:

from scrapy.signalmanager import SignalManager
from scrapy.xlib.pydispatch import dispatcher

class MySpider(CrawlSpider):
    def __init__(self, *args, **kwargs):
        super(MySpider, self).__init__(*args, **kwargs)
        SignalManager(dispatcher.Any).connect(
            self.closed_handler, signal=signals.spider_closed)

    def closed_handler(self, spider):
        # do stuff here
