爬取旅游景点的数据遇到错误

Question

为什么我爬取不了旅游景点的数据,代码如下

import requests
import parsel
import csv
import time
page=1
url = 'https://piao.qunar.com/ticket/list.htm?keyword=%E6%B2%B3%E6%BA%90&&region=&from=mpl_search_suggest&page={}'.format(page)
headers = {
    'user-agent': 'Mozilla/5.0 (Linux; Android 6.0; Nexus 5 Build/MRA58N) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/112.0.0.0 Mobile Safari/537.36 Edg/112.0.1722.58'
}
response = requests.get(url=url, headers=headers)
for page in range(1, 11):
    time.sleep(1)
    lis=[]
    for li in lis:
        title = li.css('.sight_item_caption a::attr(title)').get()  # 景区名字
        dit['景区名字'] = title
        level = li.css('.sight_item_info .level::text').get()   # 景区等级
        dit['景区等级'] = level
        area = li.css('.area a::attr(title)').get()     # 地区
        dit['地区'] = area
        address = li.css('.address span::attr(title)').get()  # 地址
        dit['地址'] = address
        string = li.css('.product_star_level em::attr(title)').get()    # 热度
        star_level = float(string.strip('热度: '))
        dit['热度'] = star_level
        intro = li.css('.intro::attr(title)').get()  # 简介
        dit['简介'] = intro
        price = li.css('.sight_item_price em::text').get()   # 价格
        dit['价格'] = price
        hot_num = li.css('.hot_num::text').get()  # 月销
        dit['月销'] = hot_num
        csv_writer.writerow(dit)
f = open('河源旅游景点.csv', mode='a', encoding='utf-8-sig', newline='')
csv_writer = csv.DictWriter(f, fieldnames=['景区名字', '景区等级', '地区', '地址', '热度', '简介', '价格', '月销'])
csv_writer.writeheader()
print(dit)
