如何在socket.io nodejs服务器上列出房间

问题描述

在问题如何创建socket.io之后取得进展多播组，我发现将房间作为完成我需要的工作的好方法.

after progress on the question how to create socket.io multicast groups, I found making rooms a great way to do what I needed.

但是，很高兴知道所有房间，而无需额外的数据结构.

However, it would be great to know about all the rooms, without an extra data-structure.

是否可以从服务器套接字获取服务器上所有房间的列表?

Is it possible to get a list of all rooms on the server from the server socket?

推荐答案

简短答案:

io.sockets.adapter.rooms

我分析了io:

我得到以下输出:

{ server:
   { stack:
      [ [Object],
        [Object],
        [Object],
        [Object],
        [Object],
        [Object] ],

        _params: [],
        middleware: [Function] },
     router: [Getter],
     __usedRouter: true,
     type: 'tcp4',

  connected: { '210837319844898486': true },
  open: { '210837319844898486': true },
  closed: {},
  closedA: [],
  rooms:
   { '': [ '210837319844898486' ],
     '/public-alfred': [ '210837319844898486' ] },
  roomClients: { '210837319844898486': [ '': true, '/public-alfred': true ] },
  oldListeners: [ [Function] ],
  _events:
   { 'set:origins': [Function],
     'set:flash policy port': [Function],
     'set:transports': [Function] } }

从单个客户端io.sockets.adapter.rooms加入会议室"public-alfred"后，包含:

after joining room "public-alfred" from a single client io.sockets.adapter.rooms contained:

 { '': [ '210837319844898486' ],
         '/public-alfred': [ '210837319844898486' ] }
