scrapy item定义

class QQHrItem(scrapy.Item):
    # define the fields for your item here like:
    # name = scrapy.Field()
    title = scrapy.Field()
    position = scrapy.Field()
    publish_data = scrapy.Field()

class QQHrItem(scrapy.Item):

# define the fields for your item here like:

# name = scrapy.Field()

title = scrapy.Field()

position = scrapy.Field()

publish_data = scrapy.Field()

定义item有什么用呢

1，区分不同的数据

2，通过isinstance(item,spideritemclass)判断数据是哪个spider的item
