Scrapy:如何以特定的json格式输出项目 [英] Scrapy: How to output items in a specific json format

问题描述

我以json格式输出抓取的数据. 默认的scrapy导出器以json格式输出字典列表. 项目类型如下:

I output the scraped data in json format. Default scrapy exporter outputs list of dict in json format. Item type looks like:

[{"Product Name":"Product1", "Categories":["Clothing","Top"], "Price":"20.5", "Currency":"USD"},
{"Product Name":"Product2", "Categories":["Clothing","Top"], "Price":"21.5", "Currency":"USD"},
{"Product Name":"Product3", "Categories":["Clothing","Top"], "Price":"22.5", "Currency":"USD"},
{"Product Name":"Product4", "Categories":["Clothing","Top"], "Price":"23.5", "Currency":"USD"}, ...]

但是我想以特定格式导出数据，如下所示:

But I want to export the data in a specific format like this:

{
"Shop Name":"Shop 1",
"Location":"XXXXXXXXX",
"Contact":"XXXX-XXXXX",
"Products":
[{"Product Name":"Product1", "Categories":["Clothing","Top"], "Price":"20.5", "Currency":"USD"},
{"Product Name":"Product2", "Categories":["Clothing","Top"], "Price":"21.5", "Currency":"USD"},
{"Product Name":"Product3", "Categories":["Clothing","Top"], "Price":"22.5", "Currency":"USD"},
{"Product Name":"Product4", "Categories":["Clothing","Top"], "Price":"23.5", "Currency":"USD"}, ...]
}

请给我任何解决方案的建议. 谢谢.
