nodejs响应数据相乘

Question

我用socket.io.my做了一个应用程序问题是当我关闭节点并再次打开时服务器响应计数是up.first time 1 resutlset send但第二次2和第三次3等等？有什么问题

客户端代码

<script>
var socket = io.connect('http://10.0.0.192:8888');

socket.on('connecting', function () {
    console.log('connecting');
});

socket.on('connect', function(s){
    console.log('connect');
    socket.emit('Baglan');
    console.log('emit-Baglan');
    socket.on('guncelle',function(data){
        console.log(new Date().getMilliseconds());
        console.dir(data);
    });
});

socket.on('reconnecting', function () {
    console.log('reconnecting');
});

socket.on('reconnect', function () {
    console.log('reconnect');
});

socket.on('reconnect_failed', function () {
    console.log('reconnect_failed');
});
</script>

和服务器

function getDataForClients() {
var d = new Array();
d.push({records:res});
//console.log(d);
return d;}
function onRequest(request, response) {
    var pathname = url.parse(request.url).pathname;
    //console.log("Request for " + pathname + " received.");
    route(handle, pathname, response, request);
}
server = http.createServer(onRequest);
io = require('socket.io').listen(server);
io.set('log level', 1);
io.sockets.on('connection', function (client) {
    //console.log(client);
    client.on("Baglan",function(){
        //console.log("user connected");
        __sockets.push(client);
        client.room="weather";
        client.records=[];
        client.join(client.room);
        if(!res)
            guncelle(false,client);
        else
            client.emit("guncelle",getDataForClients());
    });
    client.on('disconnect', function(){
        var i = __sockets.indexOf(client);
        __sockets.splice(i,1);
        client.leave(client.room);
        //console.log("user leave");
    }); 
});

server.listen(8888);
  function guncelle(v,c) {
//console.log("update");
var db = mysql.createClient({
    user: 'user',
    password: '***',
});
db.query('USE '+TEST_DATABASE);
db.query(
    "select * from table",
    function selectCb(err, results, fields) {
        if (err) {
            throw err;
        }
        res = results;
        var _data = getDataForClients();
        if(v)
            io.sockets.emit("guncelle",_data);
        else
            c.emit("guncelle",_data);
        db.end();
    }
);

}

15 ms之间有5个结果。
