scrapy 返回空的 json 文件

Question

我试图抓取这个网站，但我的蜘蛛返回空的 json，我无法理解问题出在哪里。我的代码和/或我的方法有问题吗？谢谢

import scrapy

import json

class SrealitySpider(scrapy.Spider):

    name = 'sreality'

    allowed_domains = ['www.sreality.cz/en']

    def start_requests(self):

        yield scrapy.Request(url="https://www.sreality.cz/api/en/v2/estates?category_main_cb=1&category_type_cb=2&locality_region_id=10&per_page=20&tms=1548939428469",

                            callback=self.parse_id)

    def parse_id(self, response):

        data = json.loads(response.body)

        estates = data.get("_embedded").get("estates")

        for estate in estates:

            yield scrapy.Request(url="https://www.sreality.cz/api{0}?tms=1548942301694".format(estate.get("_links").get("self").get("href")), callback=self.parse)

    def parse(self, response):

        estate = json.loads(response.body)

        yield {

                 "lat": estate.get("map").get("lat"),

                 "lon": estate.get("map").get("lon"),

                 "title": estate.get("name").get("value").replace(u'\xa0', u' '),

                 "address": estate.get("locality").get("value"),

                 "Price (czk)": estate.get("price_czk").get("value").replace(u'\xa0', u' '),

                 "nearby (m)": {prox.get("name"): prox.get("distance") for prox in estate.get("poi")},

                 "attributes": {attrib.get("name"): attrib.get("value") for attrib in estate.get("items")}

                }
