Question

heya我正在使用scrapy创建一个项目，我需要从业务目录中删除业务详细信息http://directory.thesun.co.uk/find/uk/computer-repair
我面临的问题是：当我尝试抓取页面时，我的抓取工具只获取第一页的详细信息，而我还需要获取其余9页的详细信息;那就是10页...... 我显示在我的蜘蛛代码和items.py和设置.py之下请查看我的代码并帮助我解决它

蜘蛛代码::

from scrapy.spider import BaseSpider
from scrapy.selector import HtmlXPathSelector
from project2.items import Project2Item

class ProjectSpider(BaseSpider):
    name = "project2spider"
    allowed_domains = ["http://directory.thesun.co.uk/"]
    start_urls = [
        "http://directory.thesun.co.uk/find/uk/computer-repair"
    ]

    def parse(self, response):
        hxs = HtmlXPathSelector(response)
        sites = hxs.select('//div[@class="abTbl "]')
        items = []
        for site in sites:
            item = Project2Item()
            item['Catogory'] = site.select('span[@class="icListBusType"]/text()').extract()
            item['Bussiness_name'] = site.select('a/@title').extract()
            item['Description'] = site.select('span[last()]/text()').extract()
            item['Number'] = site.select('span[@class="searchInfoLabel"]/span/@id').extract()
            item['Web_url'] = site.select('span[@class="searchInfoLabel"]/a/@href').extract()
            item['adress_name'] = site.select('span[@class="searchInfoLabel"]/span/text()').extract()
            item['Photo_name'] = site.select('img/@alt').extract()
            item['Photo_path'] = site.select('img/@src').extract()
            items.append(item)
        return items

我的items.py代码如下::

from scrapy.item import Item, Field

class Project2Item(Item):
    Catogory = Field()
    Bussiness_name = Field()
    Description = Field()
    Number = Field()
    Web_url = Field()
    adress_name = Field()
    Photo_name = Field()
    Photo_path = Field()

我的settings.py是:::

BOT_NAME = 'project2'

SPIDER_MODULES = ['project2.spiders']
NEWSPIDER_MODULE = 'project2.spiders'

请帮忙我也从其他页面中提取细节......

获取说明.select('span/text()')您正在//div[@class="abTbl "]中选择所有范围内的文字。要提取最后一个跨度，您可以使用'span[last()]/text()' xpath

btw这个http://www.w3schools.com/xpath/xpath_syntax.asp可以帮助你使用XPathes

Scrapy只抓第1页
