我是新使用scrapy，我想从一个房地产网站的一些信息。 该网站有一个搜索表单（GET方法）主页。 我试图去在我start_requests（recherche.php）的结果页面，并设置所有GET参数我在FORMDATA参数的地址栏中看到。 我还设置了饼干我有，但他也没擦出火花..
这里是我的蜘蛛：
from scrapy.spider import BaseSpider
from scrapy.selector import HtmlXPathSelector
from scrapy.http import FormRequest, Request
from robots_immo.items import AnnonceItem
class ElyseAvenueSpider(BaseSpider):
name = "elyse_avenue"
allowed_domains = ["http://www.elyseavenue.com/"]
def start_requests(self):
return [FormRequest(url="http://www.elyseavenue.com/recherche.php",
formdata={'recherche':'recherche',
'compteurLigne':'2',
'numLigneCourante':'0',
'inseeVille_0':'',
'num_rubrique':'',

},

'__utmb':'150766562.14.10.1340727680'
},
callback=self.parseAnnonces
)]
def parseAnnonces(self, response):
hxs = HtmlXPathSelector(response)
annonces = hxs.select('//div[@id="contenuCentre"]/div[@class="blocVignetteBien"]')
items = []
for annonce in annonces:
item = AnnonceItem()
item['nom'] = annonce.select('span[contains(@class,"nomBienImmo")]/a/text()').extract()
item['superficie'] = annonce.select('table//tr[2]/td[2]/span/text()').extract()
item['prix'] = annonce.select('span[@class="prixVignette"]/span[1]/text()').extract()
items.append(item)
return items
SPIDER = ElyseAvenueSpider()
当我运行的蜘蛛，是没有问题的，但加载的页面是不是一个好（它在说“请指定搜索”，我没有得到任何结果。）
