scrapy获取高德地图的城市数据

#spider页业务逻辑如下:
import scrapy
import json

class AmapSpider(scrapy.Spider):
    name = 'amap'
    allowed_domains = ['amap.com']
    start_urls = ['https://www.amap.com/service/cityList?version=201982221']
    sort_city_OK={}
    sort_province_OK={}
    item={}
    def parse(self, response):
        result=json.loads(response.text)
        dt=result["data"]
        hot_city=dt["cityData"]    #热门城市，没用
        sort_city=dt["cityByLetter"]  #按城市排
        sort_province=dt["provinceByLetter"]    #按省排

        for k,v in sort_city.items():
            self.sort_city_OK[k]=[d["name"] for d in v]

        for k,v in sort_province.items():   #k=A,B,C...
            temp_province_dict = {}
            for province in v:

                    temp_province_dict[k2]=[n["name"] for n in v2]
            self.sort_province_OK[k]=temp_province_dict
        self.item={"sort_city":self.sort_city_OK,"sort_province":self.sort_province_OK}
