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()
