socket.io如何制作自定义用户列表

Question

如何制作连接到nodejs socket.io服务器的用户的自定义列表？通过自定义，我的意思是每个用户都有像xPos，yPos，name这样的属性。从而使表看起来是

[ {xPos: 13, yPos: 42, name: "Example1"}, {xPos: 32, yPos: 53, name: "Example2"} ]

也，我不是母语，我的英语可能是太可怕了。

Answer 1

// Index users by socket id 
var ACTIVE_USERS = {}; 

io.on('connection', function(socket) { 
    socket.on('NEW_USER', function(user) { 
    // Here user can have your custom properties (xPos, yPos, etc) that can be passed in from the client 
    ACTIVE_USERS[socket.id] = user; 
    }) 

    socket.on('disconnect', function() { 
    delete ACTIVE_USERS[socket.id]; 
    }); 
}); 

// You can get active users as an array this way 
var users = Object.keys(ACTIVE_USERS).map(function(key) { 
    return ACTIVE_USERS[key]; 
})
