使用 jq 向现有 JSON 数组添加新列表、字符串和重组

Question

我有这个 input.json

{
   "list": [
      {
         "something1": "aaaa",
         "status": {
            "totalItems": 2,
            "Items": [
               {
                  "city": "santa",
                  "state": "VA",
                  "adress": "1 avenue"
               },
               {
                  "city": "manhatan",
                  "state": "NY",
                  "adress": "1 drive"
               }
            ]
         }
      },
      {
         "something1": "bbbb",
         "status": {
            "totalItems": 0
         }
      }
   ]
}

我想添加列表并在值之间附加一些文本并输出如下：

{
   "Newlist": [
      {
         "name": "NewName.aaaa",
         "HaveItem": "Yes",
         "Data": [
            "santa is a city of VA with address 1 avenue",
            "manhatan is a city of NY with address 1 drive"
         ]
      },
      {
         "name": "NewName.bbbb",
         "HaveItem": "No"
      }
   ]
}

我尝试过使用 jq '.list | map({name: .something1, HaveItem: (if .status.totalItems != 0 then "Yes" else "No" end), Data: (if .status.totalItems != 0 then .status.Items else "NULL" end) })' 但我不知道如何在值之间添加字符串。

连接两个字符串的一种方法是使用+，例如而不是

name: .something1

你会写

name: ("NewName." + .something1)

以您的查询为起点，下一步是将所有内容包装在一个以Newlist 为键的对象中：

{ Newlist:
    .list
    | map({name: ("NewName." + .something1),
           HaveItem:
             (if .status.totalItems != 0 
              then "Yes" 
              else "No" end),
           Data: 
             (if .status.totalItems != 0
              then .status.Items
              else "NULL" end)
    } ) }

您应该能够对其进行调整以产生您想要的最终结果。
