Python使用Scrapy爬取妹子图

Python Scrapy爬虫，听说妹子图挺火，我整站爬取了，上周一共搞了大概8000多张图片。和大家分享一下。

核心爬虫代码

    # -*- coding: utf-8 -*-
    from scrapy.selector import Selector
    import scrapy
    from scrapy.contrib.loader import ItemLoader, Identity
    from fun.items import MeizituItem


    class MeizituSpider(scrapy.Spider):
      name = "meizitu"
      allowed_domains = ["meizitu.com"]
      start_urls = (
        'http://www.meizitu.com/',
      )

      def parse(self, response):
        sel = Selector(response)
        for link in sel.xpath('//h2/a/@href').extract():
          request = scrapy.Request(link, callback=self.parse_item)
          yield request

        pages = sel.xpath("//div[@class='navigation']/div[@id='wp_page_numbers']/ul/li/a/@href").extract()
        print('pages: %s' % pages)
        if len(pages) > 2:
          page_link = pages[-2]
          page_link = page_link.replace('/a/', '')  
          request = scrapy.Request('http://www.meizitu.com/a/%s' % page_link, callback=self.parse)
          yield request

      def parse_item(self, response):
        l = ItemLoader(item=MeizituItem(), response=response)
        l.add_xpath('name', '//h2/a/text()')
        l.add_xpath('tags', "//div[@id='maincontent']/div[@class='postmeta clearfix']/div[@class='metaRight']/p")
        l.add_xpath('image_urls', "//div[@id='picture']/p/img/@src", Identity())

        l.add_value('url', response.url)
        return l.load_item()
