对不起，我的英语不好

我正在尝试获取所有连接的客户端数据

样本；

var a_sockets           =   io.sockets.clients();

console.log(a_sockets);

返回；

     encoder: Encoder {} },
  _events: [Object: null prototype] { connection: [Function] },
  _eventsCount: 1 }

只想获取userId数据。

我想带它[Connected-> userId]

所以我可以比较用户我怎么解决这个问题？我再次为我的英语道歉

谢谢。

如果您能帮助我，我将非常高兴。祝你有美好的一天

简短答案（假设您使用的版本> = 1.0）：

var srvSockets = io.sockets.sockets;
Object.keys(srvSockets);

节点JS获取数据io.sockets.clients（）;
