使用 JOLT 从 JSON 中的数组中有选择地获取某些数组

Question

我一直在尝试从非常长且复杂的 json 格式中获取一些字段，但没有得到我想要的输出。

我的当前规范从事件数组中获取所有事件并将它们列在输出中。我不确定如何 select 特定事件并只输出这些事件。我不太确定语法

我的JSON:

{
  "rootid": "19718",
  "clloadm": "2021-06-01T22:40:02",
  "clload": "2021-06-01T21:21:39",
  "date": "2021-05-25T21:52:30",
  "events": [
    {
      "done": {
        "id": "e0",
        "value": "2021-05-29T08:08:19"
      },
      "id": "e0_event",
      "started": {
        "id": "e0",
        "value": "2021-05-29T08:08:19"
      },
      "status": "complete"
    },
    {
      "done": {
        "id": "e1",
        "value": "2021-05-27T02:20:25"
      },
      "id": "e1_event",
      "started": {
        "id": "e1",
        "value": "2021-05-27T02:20:25"
      },
      "status": "complete"
    },
    {
      "done": {
        "id": "e2",
        "value": "2021-05-29T08:08:19"
      },
      "id": "e2_event",
      "started": {
        "id": "e2",
        "value": "2021-05-29T08:08:19"
      },
      "status": "complete"
    },
    {
      "done": {
        "id": "e3",
        "value": "2021-05-29T08:08:19"
      },
      "id": "e3_event",
      "started": {
        "id": "e3",
        "value": "2021-05-29T08:08:19"
      },
      "status": "complete"
    },
    {
      "done": {
        "id": "e4",
        "value": "2021-05-29T08:08:19"
      },
      "id": "e4_event",
      "started": {
        "id": "e4",
        "value": "2021-05-29T08:08:19"
      },
      "status": "complete"
    }
  ],
  "ids": [
    {
      "id": "id",
      "source": "source",
      "value": "value"
    },
    {
      "id": "new_id",
      "source": "new_source",
      "value": "value"
    }
  ]
}

我现在获取所有事件的 Jolt 规格：

[
  {
    "operation": "shift",
    "spec": {
      "rootid": "rootid",
      "clloadm": "clloadm",
      "clload": "clload",
      "date": "date",
      "events": {
        "*": {
          "*": {
            "@value": "@id"
          }
        }
      },
      "ids": {
        "*": {
          "@value": "@id"
        }
      }
    }
  }
]

我得到的输出：

{
  "rootid" : "19718",
  "clloadm" : "2021-06-01T22:40:02",
  "clload" : "2021-06-01T21:21:39",
  "date" : "2021-05-25T21:52:30",
  "e0" : [ "2021-05-29T08:08:19", "2021-05-29T08:08:19" ],
  "e1" : [ "2021-05-27T02:20:25", "2021-05-27T02:20:25" ],
  "e2" : [ "2021-05-29T08:08:19", "2021-05-29T08:08:19" ],
  "e3" : [ "2021-05-29T08:08:19", "2021-05-29T08:08:19" ],
  "e4" : [ "2021-05-29T08:08:19", "2021-05-29T08:08:19" ],
  "id" : "value",
  "new_id" : "value"
}

我想要的输出

{
  "rootid" : "19718",
  "clloadm" : "2021-06-01T22:40:02",
  "clload" : "2021-06-01T21:21:39",
  "date" : "2021-05-25T21:52:30",
  "e0" : [ "2021-05-29T08:08:19", "2021-05-29T08:08:19" ],
  "e4" : [ "2021-05-29T08:08:19", "2021-05-29T08:08:19" ],
  "id" : "value",
  "new_id" : "value"
}

您可以将单独的键 e0 和 e4 写为 @id 键的条件情况，同时重写 键值对的其余部分 通过"*":"&"表示如

[
  {
    "operation": "shift",
    "spec": {
      "*": "&",
      "events": {
        "*": {
          "*": {
            "@id": {
              "e0": { "@(2,value)": "&" },
              "e4": { "@(2,value)": "&" }
            }
          }
        }
      },
      "ids": {
        "*": {
          "@value": "@id"
        }
      }
    }
  }
]
