Jolt 將 JSON 鍵/值轉換為字符串數組

Question

編輯：鍵名是動態的和未知的。

我想要一個 Object 並創建一個字符串數組，其中每個鍵和值連接在一起。

我的鍵包含我需要擺脫的下划線（我有那部分工作）。 我正在努力找出將所有內容結合在一起的下一步。 （我想我錯過了如何從 RHS 引用鍵和值？）

輸入：

{
  "object": {
    "key_1": [
      "A",
      "B"
    ],
    "key_2": [
      "C"
    ],
    "key_3": [
      "D",
      "E",
      "F"
    ]
  }
}

所需的 Output：

{
  "results": [
    "key 1: A B",
    "key 2: C",
    "key 3: D E F"
  ]
}

規格：

[
  {
    "operation": "shift",
    "spec": {
      "object": {
        "*_*": "results.&(0,1) &(0,2)",
        "*": "results.&"
      }
    }
  }
]

當前規格 output：

{
  "results": {
    "key 1": [
      "A",
      "B"
    ],
    "key 2": [
      "C"
    ],
    "key 3": [
      "D",
      "E",
      "F"
    ]
  }
}

似乎您需要使用帶有連接函數的修改轉換，以及移位轉換規范，例如

[
  {
   // combine the components of the each array with one extra whitespaces between them
    "operation": "modify-overwrite-beta",
    "spec": {
      "*": {
        "*": "=join(' ',@(1,&))"
      }
    }
  },
  {
   // get rid of underscores
    "operation": "shift",
    "spec": {
      "*": {
        "*_*": "&1.&(0,1) &(0,2)"
      }
    }
  },
  {
    // generate new arrays with the first components are the keys, and second ones are the values of the previous attributes of the object
    "operation": "shift",
    "spec": {
      "*": {
        "*": {
          "$": "&",
          "@": "&"
        }
      }
    }
  },
  {
   // get concatenated values for key-value pairs with colons between them
    "operation": "modify-overwrite-beta",
    "spec": {
      "*": "=join(': ',@(1,&))"
    }
  },
  {
   // get the desired result as a single array
    "operation": "shift",
    "spec": {
      "*": {
        "@": "results[]"
      }
    }
  }
]
