Question

我正在使用v0.10.37。我的逻辑是由我的检测代码设置不正确的。

if（typeof（socket.to（key）.connected [key]）==='undefined'）

是我目前用来检测的，我也尝试过typeof（socket.to（key）.connected [key] .connected，它引发了一个未定义的错误（我将代码更改为上面的原因）。我需要代码工作，以便客户端数组在向客户端添加新的clientid时删除所有无效的clientid，以便通知可以顺利推送到客户端。

var http = require('http');
var io = require('socket.io');
server = http.createServer(function(req, res){});
server.listen(8082);
var socket = io.listen(server);
var clients = {};
socket.on('connection', function(client)
{
    client.on('setUserId',function(userid)
    {
        console.log("add");
        if(typeof(clients[userid[0]])==='undefined') 
        clients[userid[0]] = {};
        clients[userid[0]][userid[1]] = userid[1];
        console.log(clients);   
        for(var key in clients[userid[0]]) 
        {
            if (typeof(socket.to(key).connected[key]) ==='undefined') 
            delete clients[userid[0]][userid[1]];
        }   
    });
    client.on('removeUserId',function(userid)
    {
        console.log("remove");
        delete clients[userid[0]][userid[1]];
        counter = 0;
        for(var key in clients[userid[0]]) 
        counter++;
        if (counter == 0)
        delete clients[userid[0]];  
        console.log(clients);
    }); 
    client.on('message', function(msg)
    {
        if (msg.indexOf("notifications") != -1)
        {
            userid = msg.replace("notifications","");
            for(var key in clients[userid]) 
            {
                sessionid = key;
                console.log("notification sent" + msg);
                socket.to(sessionid).emit('message',msg);
            }           
        }
        else if (msg.indexOf("message") != -1)
        {
            userid = msg.replace("message","");
            for(var key in clients[userid]) 
            {
                sessionid = key;
                console.log("private message sent" + msg);
                socket.to(sessionid).emit('message',msg);
            }
        }       
        else
        {
            ids = msg.split(",");
            for (i = 0; i < ids.length;i++)
            {
                userid = ids[i];
                for(var key in clients[userid]) 
                {
                    sessionid = key;
                    displaymessage = "notifications" + msg;
                    console.log("notification sent" + displaymessage);
                    socket.to(sessionid).emit('message',displaymessage);
                }
            }
        }
    })
});

我自己修复了，问题是删除了错误的索引。

删除客户端[userid [0]] [key]

做了这个伎俩。

Nodejs检查客户端是否仍然连接
