使用Jolt重新父级JSON对象 [英] Re-parent a JSON object using Jolt

问题描述

我想使用Jolt将JSON对象向下移动一级。这是我的输入数据：

I'd like to move a JSON object down one level using Jolt. Here's my input data :

{
    "rating": {
        "primary": {
            "value": 3,
            "max": 5
        },
        "quality": {
            "value": 3,
            "max": 7
        }
    }
}

我正在使用以下规格文件：

I'm using the following spec file :

[
  {
    "operation": "shift",
    "spec": {
      "$": "NEWPARENT"
    }
  }
]

我目前正在制作此输出：

I'm currently producing this output :

{
  "NEWPARENT" : "root"
}

但是，我的目标是制作：

However, my goal is to produce :

{
  "NEWPARENT": {
    "rating": {
      "primary": {
        "value": 3,
        "max": 5
      },
      "quality": {
        "value": 3,
        "max": 7
      }
    }
  }
}

任何人都可以帮我创建正确的spec文件吗？

Can anyone help me create the proper spec file?

推荐答案

Spec

[
  {
    "operation": "shift",
    "spec": {
      "@": "NEWPARENT"
    }
  }
]

仅供参考，您看到的根是Jolt处理顶级JSON输入可以是List或Map，以及您希望能够将List转换为映射（反之亦然）。

FYI, the "root" you are seeing is an artifact of the way that Jolt deals with the fact that the top level JSON input can be either a List or a Map, and that you want to be able to Transform a List into a Map (and vice versa).

因此，jolt包装输入，以便它始终转换具有单个键root的Map，作为输入的值。

So, jolt "wraps" the input so that it is "always" transforming a Map that has a single key "root", with a value that is the input.
