这只是数据样本。在我的程序中，我将在没有任何适当模式的情况下动态获取此类对象。我将必须显示所有这些键值对。如何动态检索所有嵌套的键值对？

检索以下类型的键值对不是问题，但是 event_values 对象是最具挑战性的部分。因为如果这些数据将通过API动态地获得，该如何检索呢？

"is_false_positive": false,
"event_at": "2018-08-31T20:51:59.496Z",
"source": "MAL",
"resolution": "ALERT",
"url": "/hx/api/v3/alerts/3271",
"condition": null,
"event_id": null,
"event_type": null,
"matched_at": "2018-08-31T20:51:59.496Z",

Answer 1

不能完全确定您要做什么，但是如果我理解正确，您应该可以像这样迭代对象：

function inspect(obj, depth){
    for (let key in obj) {
        var indent = new Array(depth * 3).join(' ')
        if(typeof(obj[key]) === 'object')
           inspect(obj[key], depth + 1)
        else
           console.log(indent + key + ":" + obj[key]);
    }
}

inspect(event_values, 0);

如果它确实是一个任意键值列表，则可能还需要考虑嵌套数组。

Answer 2

我不确定您到目前为止想要达到的目标。我假设您具有非结构化的Json输入，并且您想对其进行扫描，并保留列出键的所有值。

如果我是对的，下面的代码可以完成工作：

import {data} from './data';
import {isObject, isArray, isNullOrUndefined} from 'util';


const haveToGoDeeper = val => isObject(val) || isArray(val);

const parser = val => {
  const info = [];
  let finded = {};
  for(let index in val) {
    ["is_false_positive","event_at","source","resolution","url","condition","event_id","event_type","matched_at"].forEach(k => {
        //If actual keys is on the list.
        if(k === index)
            finded[index] = val[index];
    });
    // If we have find at least 1 items on bellow array of keys, we keep it.
    if(Object.keys(finded).length > 0)
      info.push(finded);

    //Recursive section.
    if(haveToGoDeeper(val[index])) {
        info.push(...parser(val[index]));
    }

  }

  return info;
};


console.log(parser(data).filter(e => e !== null));
