socket.io中有一种方法可以在断开连接的事件中创建超时,然后检查用户是否已重新连接？

这个想法是只有在超时后没有重新连接用户时才在数据库中发出数据/保存用户状态

编辑:跟随@Are Wojciechowski回答,我已经完成了多标签和F5泛滥处理程序

我有这个简单的node.js Servercode使用socket.io(1.5):

var io = require('socket.io').listen(8080);

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

    console.log(' %s sockets connected', io.engine.clientsCount);

    socket.on('disconnect', function() {
        console.log("disconnect: ", socket.id);
    });
});

如果我运行此代码并按F5几次,在某些情况下会创建新连接,然后再断开旧连接.过了一段时间,我认为它的Heartbeat Timout,所有的连接将被关闭.看结果:

 2 sockets connected
 3 sockets connected
 4 sockets connected
 5 sockets connected
 6 sockets connected
 7 sockets connected
 8 sockets connected
 9 sockets connected
 10 sockets connected
 11 sockets connected
disconnect:  0h_9pkbAaE3ftKT9AAAL
 11 sockets connected
 12 sockets connected
 13 sockets connected
 14 sockets connected

 15 sockets connected
