无法顺利通过表格

无法顺利通过表格

我会使用

FormRequest.from_response()

哪个为您完成所有工作，因为您仍然可能会错过一些字段：

from scrapy.spider import baseSpiderfrom scrapy.selector import HtmlXPathSelectorfrom scrapy.http import FormRequest, Requestfrom robots_immo.items import AnnonceItemclass ElyseAvenueSpider(baseSpider):    name = "elyse_avenue"    allowed_domains = ["elyseavenue.com"] # i fixed this    start_urls = ["http://www.elyseavenue.com/"] # i added this    def parse(self, response):        yield FormRequest.from_response(response, formname='moteurRecherche', formdata={'recherche_distance_km_0':'20', 'recherche_type_logement':'9'}, callback=self.parseAnnonces)    def parseAnnonces(self, response):        hxs = HtmlXPathSelector(response)        annonces = hxs.select('//div[@id="contenuCentre"]/div[@]')        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[@]/span[1]/text()').extract() items.append(item)        return items
