如何在Scrapy中使用包含URL和ID的JSON并组织结果？

import scrapy
import json

class MySpider(scrapy.Spider):
    name = 'my_spider'

    def start_requests(self):
        with open('data.json') as f:
            data = json.load(f)
        
        for item in data:
            url = item['url']
            id = item['id']
            
            yield scrapy.Request(url, callback=self.parse, meta={'id': id})
    
    def parse(self, response):
        id = response.meta['id']
        url = response.url
        
        # 根据需要从response提取数据，并组织结果
        data = {
            'id': id,
            'url': url,
            'data': ...
        }
        
        # 进一步处理结果，比如存储到数据库
        
        yield data
