如何基于密钥中的字符串获取密钥和json字符串的值

问题描述

我有一个如下所示的JSON文件：

{
"rooms":{
  "operatorLimbo":[
     
  ],"pager":[
     "w0vu9ourxkdpkf0vwosrim","mekkgn9e9kdpwf2rzpkf41","upkicevngkd5s2h8o01wyz","x29ywtag4kfs0mylq2rd4v"
  ],"ru_pagers":[
     "mekkgn9e9kdpwf2rzpkf41"
  ],"ch_pagers":[
     "upkicevngkd5s2h8o01wyz"
  ],"operators":[
     "r9agylhvekcoibhrk8db8c","p94jb2ocyk5hv0ch8tivk5","v7cxhqxa3kdgik1h4t1sx0","spuvkm9nnketwnqeelqzbf"
  ],"pl_operators":[
     "spuvkm9nnketwnqeelqzbf"
  ],"clients":[
     "g99g943hlkh0kp1864rwpz","prky4witjkh0naaswiewzs"
  ],"pl_users":[
     
  ],"ru_operators":[
     "r9agylhvekcoibhrk8db8c"
  ],"ch_operators":[
     "v7cxhqxa3kdgik1h4t1sx0"
  ],"nl_operators":[
     "p94jb2ocyk5hv0ch8tivk5"
  ],"nl_pagers":[
     "w0vu9ourxkdpkf0vwosrim"
  ],"ch_users":[
     "prky4witjkh0naaswiewzs"
  ],"nl_users":[
     "g99g943hlkh0kp1864rwpz"
  ],"pl_pagers":[
     "x29ywtag4kfs0mylq2rd4v"
  ],"ru_users":[
     
  ],"us_operators":[
     
  ],"au_operators":[
     
  ],"au_users":[
     
  ],"au_pagers":[
     
  ],"za_operators":[
     
  ],"yoiqfvvvokh0kp2v53sic9":{
     "roomid":"yoiqfvvvokh0kp2v53sic9","type":"1to1","ujid":"g99g943hlkh0kp1864rwpz","aid":"3173aaacd43941c7bef1a99e0057ba2b","operator":{
        "fullname":"Operator","name":"Operator","lastname":"Jura"
     },"members":[
        "Ss0G3RcclvOO8I03AAIp","jZGZ_yAb-SC3bEpmAAJz"
     ],"chatRecord":11151,"ojid":"p94jb2ocyk5hv0ch8tivk5","usid":"jZGZ_yAb-SC3bEpmAAJz"
  },"deomjtr27kh0l52ogg9zxh":{
     "roomid":"deomjtr27kh0l52ogg9zxh","ujid":"prky4witjkh0naaswiewzs","members":[
        "DPeOVb1P6qCVXO6GAAJi","AAkb84mpMxLzFHklAAJ7"
     ],"chatRecord":11153,"ojid":"v7cxhqxa3kdgik1h4t1sx0","usid":"AAkb84mpMxLzFHklAAJ7"
  }
  }
}

我感兴趣的是获取ch_operators和pl_operators等值，基本上所有包含_operators的条目以及它的值，

使用以下代码，我只能得到键，也要如何获得值，

Object.keys(this.rooms).filter((key) => key.includes("_operators"))

任何帮助将不胜感激。

解决方法

您可以结合使用Object.entries，.filter和Object.fromEntries来创建具有选定属性的新对象：

Object.fromEntries(
  Object.entries(this.rooms).filter(([key]) => key.includes("_operators"))
)

Object.entries返回一个包含键和值的数组（作为“元组”），而Object.fromEntries从该数组中构建一个新对象。
