如何使用 JOLT 规范从一个根元素向嵌套数组中添加 2 个元素？

Question

输入：

{
"k1": "v1",
"k2": "v2",
"event": "SUMMARY"
}

预期输出：

{
  "k1": "v1",
  "k2": "v2",
  "event": "SUMMARY",
  "arr": [
    {
      "k1": "v1",
      "key": "first"
    },
    {
      "k2": "v2",
      "key": "second"
    },
    {
      "summary1": "s1",
      "key": "SUMMARY"
    },
    {
      "summary1": "s2",
      "key": "SUMMARY"
    }
  ]
}

对于每个'k1'和'k2'，各自的数组元素应该添加为

{
"k2": "v2",
"key": "second"
}

当 event = "SUMMARY" 时，应分别添加 2 个元素

{
"summary1": "s1",
"key": "SUMMARY"
},
{
"summary2": "s2",
"key": "SUMMARY"
}

请帮助了解 JOLT 规范

由于您根据我写的内容提供了输入和输出 javascript 中的一个函数。

{ “k1”：“v1”， “k2”：“v2”， “事件”：“摘要” }

该功能仅适用于上述输入

而且您还必须提到您是否想要以哪种语言输出...

//Input

var obj = {
    "k1": "v1",
    "k2": "v2",
    "event": "SUMMARY"
}

//funciton calling 
obj["arr"] = checkThis(obj);



//output
console.log(obj)




function checkThis(obj) {
    var arr = [];
    Object.keys(obj)
        .forEach(function eachKey(key) {
            if (key == "k1") {
                var tempObj = {}
                tempObj["k1"] = obj[key];
                tempObj["key"] = "first";
                arr.push(tempObj)
            } else if (key == "k2") {
                var tempObj = {}
                tempObj["k2"] = obj[key];
                tempObj["key"] = "second";
                arr.push(tempObj)
            } else if (key == "event") {
                var tempObj1 = {}
                var tempObj2 = {}
                tempObj1["summary1"] = "s1";
                tempObj1["key"] = obj[key];
                tempObj2["summary1"] = "s2";
                tempObj2["key"] = obj[key];
                arr.push(tempObj1)
                arr.push(tempObj2)
            }
        });                        
return arr;
}
