Question

创建完工程后，首先要做的是定义Item，确定我们需要提取的结构化数据。主要定义两个Item，一个负责装载小说的基本信息，一个负责装载小说热度（点击量和人气等）的信息。代码如下：

  import scrapy
  
  
  class YunqiBookListItem(scrapy.Item):
     # 小说id
     novelId = scrapy.Field()
     # 小说名称
     novelName = scrapy.Field()
     # 小说链接
     novelLink = scrapy.Field()
     # 小说作者
     novelAuthor = scrapy.Field()
     # 小说类型
     novelType = scrapy.Field()
     # 小说状态
     novelStatus = scrapy.Field()
     # 小说更新时间
     novelUpdateTime = scrapy.Field()
     # 小说字数
     novelWords = scrapy.Field()
     # 小说封面
     novelImageUrl = scrapy.Field()
  
  class YunqiBookDetailItem(scrapy.Item):
     # 小说id
     novelId = scrapy.Field()
     # 小说标签
     novelLabel  =scrapy.Field()
     # 小说总点击量
     novelAllClick = scrapy.Field()
     # 月点击量
     novelMonthClick = scrapy.Field()
     # 周点击量
     novelWeekClick = scrapy.Field()
     # 总人气
     novelAllPopular = scrapy.Field()
     # 月人气
     novelMonthPopular = scrapy.Field()
     # 周人气
     novelWeekPopular = scrapy.Field()
     # 评论数
     novelCommentNum = scrapy.Field()
     # 小说总推荐
     novelAllComm = scrapy.Field()
     # 小说月推荐
     novelMonthComm = scrapy.Field()
     # 小说周推荐
     novelWeekComm = scrapy.Field()
