cd DoubanImgs

scrapy genspider download_douban douban.com

vim spiders/download_douban.py

# coding=utf-8from scrapy.spiders import Spiderimport refrom scrapy import Requestfrom ..items import DoubanImgsItemclass download_douban(Spider): name = 'download_douban' default_headers = { 'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8', 'Accept-Encoding': 'gzip, deflate, sdch, br', 'Accept-Language': 'zh-CN,zh;q=0.8,en;q=0.6', 'Cache-Control': 'max-age=0', 'Connection': 'keep-alive', 'Host': 'pleted(self, results, item, info): image_paths = [x['path'] for ok, x in results if ok] if not image_paths: raise DropItem("Item contains no images") item['image_paths'] = image_paths return item
