Question

以下代码运行，但是我无法从中获取任何数据。我正在尝试抓取the Airbnb website，我猜想我在'logements'变量上做错了什么，我是随机选择标签的，但仍然不知道它在哪里弄乱了。我在另一个网站上使用了此代码，并且可以正常工作，所以我非常感谢您的帮助。

import scrapy


class BarceloneSpider(scrapy.Spider):
    name = 'barcelone'
    start_urls = ['https://www.airbnb.fr/s/Barcelone--Espagne/homes?checkin=2https://www.airbnb.fr/s/Barcelone--Espagne/homes?refinement_paths%5B%5D=%2Fhomes&current_tab_id=home_tab&selected_tab_id=home_tab&place_id=ChIJ5TCOcRaYpBIRCmZHTz37sEQ&search_type=pagination&screen_size=medium&hide_dates_and_guests_filters=false&checkin=2020-01-24&checkout=2020-01-27&adults=2&s_tag=Kc7JRtKj&section_offset=5&items_offset=18&last_search_session_id=4b5ab129-f6dd-45ff-91e0-5c6bf9591c25']

    def parse(self, response):
        data={}
        logements= response.css('div.FMP-target')

        for logement in logements:
            for l in logement.css('span._1llb8an::text'):
                data['price']= l.getall()
                yield data

输出：
