我不知道为什么我无法获得任何结果，而每次发射沙皮鱼时我都得到相同的结果，这是我的蜘蛛：
class MercadoSpider(CrawlSpider):
name = 'mercado'
item_count = 0
allowed_domain = ['https://www.mister-auto.es']
start_urls = ['https://www.mister-auto.es/global_search2.html?
idx=prod_monoindex_ESes&q=FEBI+BILSTEIN']
rules = {
Rule(LinkExtractor(allow =(), restrict_xpaths = ('//*
[@id="pagination2"]/ul/li[11]/a'))),
Rule(LinkExtractor(allow =(), restrict_xpaths =
('//div[@class="produit_header_name"]')),
callback = 'parse_item', follow = False)
}
def parse_item(self, response):
ml_item = MercadoItem()
#info de producto
ml_item['articulo'] = response.xpath('normalize-space(//h1)').extract()
ml_item['precio'] = response.xpath('normalize-space(//span[@class="prix"])').extract()
self.item_count += 1
yield ml_item "
请你能帮我吗？ 我试图更换蜘蛛但没有结果。
