节点中的javascript对象值

在 nodejs 的控制台日志中 . 尝试读取对象中的对象但结果不正确 . 这就是我想要做的事情：请耐心等待我阅读 . 不确定如何正确格式化 .

我跑了这个我得到以下结果 .

console.log(Object.values(room));


[ 'helloRoom',
  'b19b29e4-c61f-4425-927e-4290a3e8b309mw',
  { 'b19b29e4-c61f-4425-927e-4290a3e8b309mw': 
     WebSocket {
       domain: null,
       _events: [Object],
       _eventsCount: 2,
       _maxListeners: undefined,
       readyState: 1,
       bytesReceived: 0,
       extensions: {},
       protocol: 'echo-protocol',
       _binaryType: 'nodebuffer',
       _finalize: [Function],
       _finalizeCalled: false,
       _closeMessage: null,
       _closeTimer: null,
       _closeCode: null,
       _receiver: [Receiver],
       _sender: [Sender],
       _socket: [Socket],
       _ultron: [Ultron],
       protocolVersion: 13,
       _maxPayload: 104857600,
       _isServer: true,
       id: 'b19b29e4-c61f-4425-927e-4290a3e8b309mw',
       room: 'b19b29e4-c61f-4425-927e-4290a3e8b309mw',
       is_host: true } },
  [ 'b19b29e4-c61f-4425-927e-4290a3e8b309mw' ],
  'b19b29e4-c61f-4425-927e-4290a3e8b309mw' ]

然后我跑了这个：

for(var s in room){
        console.log(s);
       }

我得到以下结果：

name
id
sockets
users
host

这样做：

console.log(room.id);

我得到以下内容：

a5c6ac55-89a3-4f06-aace-81179674fdedmw

这样做：console.log（Object.values（room.sockets））;我明白了：

    room: 'a5c6ac55-89a3-4f06-aace-81179674fdedmw',
    is_host: true } ]

我想要的是 room.socket.id

我试过了：

console.log(room.sockets.id);

我明白了：

undefined

我试过了：

console.log(Object.values(room.sockets.id));

我明白了：

TypeError: Cannot convert undefined or null to object

我怎么能自己得到 room.sockets.id ？

[更新] Sutarmin Anton的评论有效 .

“... room.sockets实际上是一个对象 . 使用

Object.keys（room.sockets）

哪个应该从room.sockets对象的键获取id并返回它们的数组 . 或者，如果你坚持从每个套接字的id属性获取id，那么

Object.values（room.sockets）.map（socket => socket.id）“
