*******************items.py********************
import scrapy
class ManhuaItem(scrapy.Item):
    # define the fields for your item here like:
    # name = scrapy.Field()  
    name=scrapy.Field()       #公司名称
    duty=scrapy.Field()     #工作的标题
    location=scrapy.Field()     #公司地址
    sallary=scrapy.Field()     #薪水
    time=scrapy.Field()    #时间

  最后在控制台运行即可：scrapy crawl demo -o file.csv
