我目前的代码面临以下问题，以使其正常运行。我只是连接了URL，但无法正常工作：
当前相对路径（这是我通过常规response.xpath爬取得到的）：
/imagename.jpg
这是我当前的代码：
class MercadoSpider(CrawlSpider):
name = 'extractor'
item_count = 0
rules = {
# Para cada item
Rule(LinkExtractor(allow = (), restrict_xpaths = ('//*[@id="main-container"]/div/div[2]/div[1]/ul/li[7]/a'))),
Rule(LinkExtractor(allow =(), restrict_xpaths = ('//*[@id="main-container"]/div/div[2]/div[2]/div/div/div/h4/a')),
callback = 'parse_item', follow = False)
}
def parse_item(self, response):
ml_item = MercadoItem()
ml_item['titulo'] = response.xpath('normalize-space(//*[@id="main-container"]/div/div[2]/div[1]/div[2]/h2)').extract_first()
ml_item['sku'] = response.xpath('normalize-space(//*[@id="main-container"]/div/div[2]/div[1]/div[2]/ul/li[2]/a)').extract()

#info de la tienda o vendedor
ml_item['categoria'] = response.xpath('normalize-space(//*[@class="woocommerce-breadcrumb breadcrumbs"])').extract_first()
self.item_count += 1
if self.item_count > 10000:
raise CloseSpider('item_exceeded')
yield ml_item
