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()
