Web服务器所需的socket.setTimeout代码

如何解决Web服务器所需的socket.setTimeout代码

大家好，我正在制作一个网络聊天服务器。现在由于发生了错误，我需要添加一个socket.io超时来仅断开超时的客户端而不断开每个在线的客户端。但是我不明白如何在此服务器中使用socketio.setTimeout();。我需要协助！。 我将附上我的server.js代码：

var express = require("express");
if (express)
{
    console.log("Express.JS found.");
}
var socket = require("socket.io");
if (socket)
{
    console.log("Socket.IO found.");
}
// Files found

// http server
var http = require("http");
var app = express();
var server = http.Server(app);
var users = [];
var io = require("socket.io")(server);
var count = 0;
server.listen(80,function () {
    console.log("Server running at port 80.")
});
app.get("/",function(req,res) {
    res.sendFile(__dirname + "/index.html");
})
io.on("connection",function(socketio) {
    var name = "";
    socketio.on("has connected",function (username) {
        name = username;
        users.push(username);
        io.emit("has connected",{username: username,usersList: users});
        count = count+1;
        console.log(count+": <SERVER-THREAD-INFO>: "+name + " has connected. Online Users: " + users);
    });
    socketio.on("disconnect",function() {
        users.splice(users.indexOf(name),1);
        io.emit("has disconnected",{username: name,usersList: users});
        count = count+1;
        console.log(count+": <SERVER-THREAD-INFO>: "+name + " has disconnected. Online Users: " + users);
    });
    socketio.on("new message",function(message) {
        io.emit("new message",message);
        count = count+1;
        console.log(count+": <SERVER-USER-MESSAGE>: "+name+": "+message.message);
    });
