【问题描述】：
我是使用scrapy 的新手，我正在尝试从房地产网站获取一些信息。 该站点有一个带有搜索表单的主页（方法 GET）。 我正在尝试转到我的 start_requests (recherche.php) 中的结果页面，并在 formdata 参数中设置我在地址栏中看到的所有获取参数。 我还设置了我拥有的 cookie，但他也没有工作..
这是我的蜘蛛：
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':'',
'rechercheOK':'recherche',
'recherche_budget_max':'',
'recherche_budget_min':'',
'recherche_surface_max':'',
'recherche_surface_min':'',
'recherche_distance_km_0':'20',
'recherche_reference_bien':'',
'recherche_type_logement':'9',
'recherche_ville_0':''
},
cookies={'PHPSESSID':'4e1d729f68d3163bb110ad3e4cb8ffc3',
'__utma':'150766562.159027263.1340725224.1340725224.1340727680.2',
'__utmc':'150766562',
'__utmz':'150766562.1340725224.1.1.utmcsr=(direct)|utmccn=(direct)|utmcmd=(none)',
'__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()
当我运行蜘蛛时，没有问题，但加载的页面不是很好（它说“请指定您的搜索”，我没有得到任何结果..）
