在main.py中使用

#execute(['scrapy','crawl','mj_spider'])
#execute(['scrapy','crawl','gd_spider'])

启动spider时可以正常写入elasticsearch

当使用下面这种方式时====

import scrapy
from scrapy.crawler import CrawlerProcess
from spiders.onem3spider import MJSpider
from spiders.gd_spider import GdSpiderSpider
from twisted.internet import reactor, defer
from scrapy.crawler import CrawlerRunner
from scrapy.utils.log import configure_logging

configure_logging()
runner = CrawlerRunner()

@defer.inlineCallbacks
def crawl():
   yield runner.crawl(MJSpider)
   yield runner.crawl(GdSpiderSpider)
   reactor.stop()

crawl()
reactor.run() # the script will block here until the last crawl call is finished

就无法写入elasticsearch了，这是什么原因？
