我想用Socket.io将每30秒重新连接到服务器应用程序

Question

我希望客户端每30秒连接一次到服务器并建立新连接。我想更改用户断开连接的时间。

客户端：

<script>
        var socket = io.connect('http://localhost:3000', {
            'reconnect': true,
            'force new connection': true
        });
        socket.on('connect', function (data) {
            socket.emit('storeClientInfo', { customId:"123456789",'sessionId':"asd2131ad113ad" });
        });
</script>

服务器端：

var app = require('express')();
var http = require('http').Server(app);
var io = require('socket.io')(http);
var exec = require("child_process");
var people = [];

io.on('connection', function(socket){
    var peop = {};

    socket.on('storeClientInfo', function (data) {
        var status = new Date().getTime();
        console.log('login:' +status);
        socket.on('disconnect', function(){
            var status = new Date().getTime();
            console.log('logout:' +status);
        });
    });
});

http.listen(3000, function(){
    console.log('listening on *:3000');
});

输出登录信息：

login:1416837382116
logout:1416837407535
login:1416837410118
logout:1416837435537
login:1416837438115

必须在30秒后完成注销。 我尝试改变这些值：

  io.set('heartbeat timeout', );
  io.set('heartbeat interval', );

但我没有成功获得正确的结果。

编辑后的代码：

io.on('connection', function(socket){

socket.on('storeClientInfo', function (data) {
    var userId = data.customId;
    var userIpAddress= socket.request.socket.remoteAddress;
    var status = new Date().getTime()+65000;
    if (typeof people[userId] == 'undefined') {
        people[userId] = {userId: userId,status:status};
        console.log(userId + ' logged. Ip address: '+ userIpAddress);
    } else {
        people[userId] = {userId: userId,status:status};
    }

    socket.on('disconnect', function(){
         setTimeout(function () {
            var now = new Date().getTime();
            if (typeof people[userId] != 'undefined'){
                if (people[userId].status < now) {
                    exec.exec("php some.php " + data.customId, function(err, stdout, stderr) { console.log(userId + " logout!"); });
                    delete people[userId];
                }
            }
        }, 125000);
    });
});

}）;
