Node.js + Socket.io：当用户由于不活动而断开连接时，检测客户端

Question

I want to detect client-side when a user has disconnected due to INACTIVITY . For me, using a disconnect() event doesn't work because it encompasses other forms of a client disconnecting besides inactivity.

My current code:

var socket = io.connect();

socket.on("disconnect", () => {
    console.log("You have been disconnected from the match.");
});

Answer 1

This might help you!

 var socket = io.connect(); socket.on("disconnect", () => { //it emits a logoff event socket.emit("logoff", { reason: "Disconnected due to inactivity" }); console.log("You have been disconnected from the match."); }); 

Answer 2

On your server side:

io.on('connection', function(socket){
  socket.on('disconnect', function(){
    console.log('user disconnected'); // client has been disconnected, client maybe has many connections.
  });
});

Orther way, Client side takes a http request to noti to server that it has been disconnected.

var socket = io.connect();

socket.on("disconnect", () => {
    console.log("You have been disconnected from the match.");
    $.post('http://serverdomain/socket/' + socket.id + '/disconnected') // Just make a http request,
    // example by jQuery
});
