【问题描述】：
我正在尝试将此 JSON 转换为数组，以便我可以简单地将它们列为 html 中的键值对。 JSON 具有我想保留的嵌套属性，但我只想对那些包含“单位”和“值”的对象进行字符串化。所有其他应列为子项。请帮助弄清楚我做错了什么。
这是 json 输入：
{
"clusterName": "ml6.engrlab.com-cluster",
"statusProperties": {
"loadProperties": {
"loadDetail": {
"restoreWriteLoad": {
"value": 0,
"units": "sec/sec"
},
},
"totalLoad": {
"value": 0.0825921967625618,
"units": "sec/sec"
}
},
"secure": {
"value": false,
"units": "bool"
},
"statusDetail": {
"licenseKeyOption": [
{
"value": "conversion",
"units": "enum"
},
{
"value": "failover",
"units": "enum"
}
],
"connectPort": 7999,
"softwareVersion": {
"value": 9000100,
"units": "quantity"
}
},
"rateProperties": {
"rateDetail": {
"largeReadRate": {
"value": 0,
"units": "MB/sec"
}
},
"totalRate": {
"value": 67.2446365356445,
"units": "MB/sec"
}
},
"online": {
"value": true,
"units": "bool"
},
"cacheProperties": {
"cacheDetail": {
"tripleCachePartitions": {
"tripleCachePartition": [
{
"partitionSize": 768,
"partitionBusy": 0,
"partitionUsed": 0,
"partitionFree": 100
}
]
}
}
}
}
}
我的代码
function isNested(obj) {
if(!obj) return false;
let propArry = Object.keys(obj)
for(let i=0; i<propArry.length; i++){
if(obj[propArry[0]].constructor.name === 'Object') return true
}
return false;
}
function getKeyValueAsChildren(obj) {
let vals = [];
for(let key in obj) {
if(obj.hasOwnProperty(key)){
vals.push({key:key, value: obj[key]})
}
}
return vals
}
function valueAsString(obj) {
if(typeof obj !== 'object') return obj;
return `${obj['value']} ${obj['units']}`
}
function getChildren(key, obj) {
if(Object.keys(obj).sort().toString() === "units,value"){
return {key: key, value: valueAsString(obj)}
} else {
return {key: key, children: getKeyValueAsChildren(obj) }
}
}
function getValues(properties, values = []) {
for(let key in properties) {
if(properties.hasOwnProperty(key)) {
let value = properties[key]
if(typeof value !== 'object') {
values.push({key: key, value: value})
} else if(Array.isArray(value)){
let children = []
value.map(v => {
children.push(getChildren(key, v))
})
values.push({key: `${key}List`, children: children})
}
else if(value.constructor.name === 'Object' && isNested(value)){
// I THINK THE MAIN PROBLEM IS HERE
let keys = Object.keys(value)
let children = [];
keys.forEach(key => {
children.push({key: key, children: getValues(value[key])})
})
values.push({key: key, children: children})
}
else {
values.push(getChildren(key, value))
}
}
}
return values
}
getValues(hostProperties)
这会返回
[
{
"key": "clusterName",
"value": "ml6.engrlab.com-cluster"
},
{
"key": "statusProperties",
"children": [
{
"key": "loadProperties",

"value": "sec/sec"
}
]
}
]
},
{
"key": "totalLoad",
"value": "0.0825921967625618 sec/sec"
}
]
},
{
"key": "secure",

},

}
]
},

},

},
]
},
{

}
]
},
{

{
"key": "partitionFree",
"value": 100
}
]
}
]
}
]
}
]
}
]
}
]
}
]
但我需要这个

{
"key": "loadProperties",

嗨，这确实是我问题的最简化形式。 JSON比我发布的要大得多。我已经缩减到涵盖我需要处理的所有情况的小型集合。我正在寻找的输出格式非常适合我的需求
