我正在尝试通过scrapy下载图像。这是我的不同文件:

items.py

class DmozItem(Item):
        title = Field()
        image_urls = Field()
        images = Field() 

settings.py

BOT_NAME = 'tutorial'

SPIDER_MODULES = ['tutorial.spiders']
NEWSPIDER_MODULE = 'tutorial.spiders'
ITEM_PIPELINES = ['scrapy.contrib.pipeline.images.ImagesPipeline']
IMAGES= '/home/mayank/Desktop/sc/tutorial/tutorial'
蜘蛛

class DmozSpider(BaseSpider):
    name = "wikipedia"
    allowed_domains = ["wikipedia.org"]
    start_urls = [
        "http://en.wikipedia.org/wiki/Pune"
    ]

    def parse(self, response):
        hxs = HtmlXPathSelector(response)
        items = []
        images=hxs.select('//a[@class="image"]')
        for image in images:
                item = DmozItem()
                link=image.select('@href').extract()[0]
                link = 'http://en.wikipedia.com'+link
                item['image_urls']=link
                items.append(item)

尽管有这些设置,但我的管道没有被激活。请帮助。我是这个框架的新手。

首先,settings.py:IMAGES - > IMAGES_STORE

其次,spider:您应该返回item,以便ImagesPipeline可以下载这些图片。

item = DmozItem()
image_urls = hxs.select('//img/@src').extract()
item['image_urls'] = ["http:" + x for x in image_urls]
return item
