Handle browser reload socket.io
提问by m4tm4t
There is a way in socket.io to create a timeout in the disconnected event, then check if the user has been reconnected ?
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？
The idea is to emit data / save user state in database only if the user is not reconnected after timeout
这个想法是仅当用户在超时后没有重新连接时才在数据库中发出数据/保存用户状态

There is a socket.on('disconnect', function () { ... });.
So you can just do
有一个socket.on('disconnect', function () { ... });。所以你可以做
socket.on('disconnect', function () {
setTimeout(function () {
//do something
}, 10000);
});
EDIT 1:

I get it now. So maybe you should do something like this:
我现在明白了。所以也许你应该做这样的事情：
Client:
客户：
//right after connection
socket.emit('register', localstorage.getItem('gameUniqueId'));
//somewhere, when game starts
var randomlyGeneratedUID = Math.random().toString(36).substring(3,16) + +new Date;
localStorage.setItem('gameUniqueId', randomlyGeneratedUID);
Server:
服务器：
io.sockets.on('connection', function (socket) {
var player = null;
socket.on('register', function (data) {
if (data !== null) {
//there was something in localstorage
if (game.Players.existsUID(data)) {
player = game.Players.getByUID(data);
player.disconnected = false;
} else {
//timed out, create new player
}
} else {
//localStorage is not set, create new player
}
});
socket.on('disconnect', function () {
player.disconnected = true;
setTimeout(function () {
if (player.disconnected) player.delete();
}, 10000);
});
});
