Why do you use scarpy to climb Dianping's city home page with content, but you can't get it when you climb by area?

as shown in the figure below, when the page is the food section of the whole city, for example, the URL of Xi"an food is "http://www.dianping.com/xian/ch10", you can crawl the data normally (figure 1).

50"http://www.dianping.com/xian/..."

Please take a look at what went wrong! Thank you very much.

I tried to run the site with scrapy shell, but what I opened with view (response) was an empty txt document, not a web page.

here is my code
dianping.py

import scrapy
import requests
from scrapy.selector import Selector
from ..items import DianpingItem


class DianpingSpider(scrapy.Spider):
    name = "dianping"
    start_urls = ["http://www.dianping.com/xian/ch10/r8915/"]

        Dianping = DianpingItem()
        title_list = response.xpath("//div[@class="tit"]/a[1]/h4/text()").extract()

        -sharp recommend_list2 = recommend_list1[0].xpath("string(.)").extract()
        -sharp recommend_list = [item.replace(" ", "").replace("\n", "|") for item in recommend_list2]
        for i1, i2, i3, i4, i5,i6,i7,i8,i9,i10,i11 in zip(title_list,level_list,comment_list,price_list,kouwei_list,huanjing_list,fuwu_list,caixi_list,area_list,address_list,recommend_list):

            Dianping["recommend"] = i11
            yield Dianping
        next_pages = response.xpath("//div[@class="page"]/a[@class="next"]/@href").extract()
