使用项目字段中的内容重命名Scrapy 0.24中下载的图像，同时避免文件名冲突？

pipes.py：

from scrapy.pipelines.images import ImagesPipelinefrom scrapy.http import Requestfrom scrapy.exceptions import DropItemfrom scrapy import logclass MyImagesPipeline(ImagesPipeline):    #Name download version    def file_path(self, request, response=None, info=None):        image_guid = request.meta['model'][0]        log.msg(image_guid, level=log.DEBUG)        return 'full/%s' % (image_guid)    #Name thumbnail version    def thumb_path(self, request, thumb_id, response=None, info=None):        image_guid = thumb_id + request.url.split('/')[-1]        log.msg(image_guid, level=log.DEBUG)        return 'thumbs/%s/%s.jpg' % (thumb_id, image_guid)    def get_media_requests(self, item, info):        yield Request(item['image_urls'][0], meta=item)

您使用的是

settings.py

ITEM_PIPELINES = {'allenheath.pipelines.MyImagesPipeline': 1}

为了使缩略图起作用，请将其添加到

settings.py

IMAGES_THUMBS = {    'small': (50, 50),    'big': (100, 100),}
