关于scrapy问题

lichanglin1987

这是items.py代码

import scrapy



class CeshiItem(scrapy.Item):
    # define the fields for your item here like:
    # name = scrapy.Field()
    prince = scrapy.Field()
    bookname = scrapy.Field()



这是我的spider.py代码

# -*- coding: utf-8 -*-
import scrapy
from ceshi.items import CeshiItem

class BookSpider(scrapy.Spider):
    name = 'book'
    allowed_domains = ['https://market.douban.com/']
    start_urls = ['https://market.douban.com/book/?utm_campaign=book_freyr_section&utm_source=douban&utm_medium=pc_web&page=1&page_num=18&']

    def parse(self, response):
        bookItem = []
        item = CeshiItem(scrapy.Item)
        booklist = response.xpath('//div[@class="panel-detail"]')
        for each in booklist:
            item['prince'] = each.xpath('./span[@class="book-price"]/i/text()').extracrt()[0]
            item['bookname'] = each.xpath('./div[@class="book-brief"]/h3/text()').extract()[0]

            bookItem.append(item)

        return bookTtem

为啥我最后模拟得出来的是个空列表。哪里出问题了吗

数据匹配有问题吧，去调试看看
