Question

我正在尝试学习网络套接字。我开发了一个聊天的Web应用程序，它在本地服务器上工作得很好，但在我的VPS上却没有。似乎我的网址“ws：//”+ document.location.host +“/ TikTok / wschat”存在问题。如果有人能帮助我，请告诉我。我是学习者，请不要介意我的英语。我正在使用基于linux的vps与java 8和tomcat 7.提前感谢

与'ws：//tiktokchat.tk：8084 / wschat'的WebSocket连接失败：错误在连接建立：net :: ERR_CONNECTION_REFUSED

var ws=null;
var wsUri = "ws://" + document.location.host+"/TikTok/wschat";
console.log(wsUri);
ws = new WebSocket(wsUri);
ws.onmessage = function(message){
    document.getElementById("chatlog").textContent += message.data + "\n";
};
function postToServer(name){
    ws.send(name+">>>"+document.getElementById("groupMsg").value);
    document.getElementById("groupMsg").value = "";
};
function closeConnect(){
    ws.close();
};

<div id='groupchat'>
<textarea id="chatlog" readonly></textarea><br/>
<input id="groupMsg" type="text" />
<button type="submit" id="sendButton" onClick="postToServer('${username}')">Send!</button>
<button type="submit" id="sendButton" onClick="closeConnect()">End</button>
</div>

package com.tiktok.controller;

import java.io.IOException;
import java.util.ArrayList;

import javax.websocket.OnClose;
import javax.websocket.OnMessage;
import javax.websocket.OnOpen;
import javax.websocket.Session;
import javax.websocket.server.ServerEndpoint;

@ServerEndpoint(value = "/wschat")
public class WsChat{
    //notice:not thread-safe
    private static ArrayList<Session> sessionList = new ArrayList<Session>();

    @OnOpen
    public void onOpen(Session session){
        try{
            sessionList.add(session);
            //asynchronous communication
            session.getBasicRemote().sendText("Welcome!");
        }catch(IOException e){}
    }

    @OnClose
    public void onClose(Session session){
        System.out.println("close");
        sessionList.remove(session);
    }

    @OnMessage
    public void onMessage(String msg){
        System.out.println("message");
        try{
            for(Session session : sessionList){
                //asynchronous communication
                session.getBasicRemote().sendText(msg);
            }
        }catch(IOException e){}
    }
}

vps的网络套接字网址？
