websocket和webserver保持80端口

Question

我拥有域（例如：mydomain.com）

我想通过域连接到套接字

P.S。现在我正在连接到本地网络套接字var socket = new WebSocket("ws://localhost:8080");

如何将Web服务器和WebSocket保持在80端口上（因为它们冲突）？

如何使用域（如var socket = new WebSocket("ws://echo.websocket.org");）建立与套接字的连接？

我读到有关Apache代理的信息...但是我不明白该怎么办...

我正在使用OpenServer

<script>
window.onload = function(){
    var socket = new WebSocket("ws://localhost:8080");
    var status = document.querySelector("#status");

    socket.onopen = function() {
        status.innerHTML += `<i class="ui orange label">Connected</i>`;
        status.scrollTop = status.scrollHeight;
    };

    socket.onclose = function(event) {
        if (event.wasClean) {

        }
    };

    socket.onerror = function(event) {

    };

    document.forms["messages"].onsubmit = function(){
        let message = {
            msg:  ' ' + this.msg.value,
            from: this.from.value,
        };
        socket.send(JSON.stringify(message));
        return false;
    };

    socket.onmessage = function(event) {
        let message = JSON.parse(event.data);

        var hd = document.querySelector("#hidden_content");

        hd.innerHTML += `<div class="ui segment" style="min-height: 40px; word-break: break-all; min-width: 80%;">New message from ${message.username}</div>`;

    };
}
