问题描述
I am trying to run Scrapy from Python. I'm looking at this code which (source):
from twisted.internet import reactor
from scrapy.crawler import Crawler
from scrapy.settings import Settings
from scrapy import log
from testspiders.spiders.followall import FollowAllSpider
spider = FollowAllSpider(domain='scrapinghub.com')
crawler = Crawler(Settings())
crawler.configure()
crawler.crawl(spider)
crawler.start()
log.start()
reactor.run() # the script will block here
My issue is that I'm confused on how to adjust this code to run my own spider. I have called my spider project "spider_a" which specifies the domain to crawl within the spider itself.
What I am asking is, if I run my spider with the following code:
scrapy crawl spider_a
How do I adjust the example python code above to do the same?
解决方案
Just import it and pass to crawler.crawl(), like:
from testspiders.spiders.spider_a import MySpider
spider = MySpider()
crawler.crawl(spider)
