swooleWebSocket

1：先创建服务端文件WebSocket.php

<?php

class WebSocket
{
    private $ws = null;
    
    public function __construct(){
        //创建WebSocket Server对象，监听0.0.0.0:9502端口
        $this -> ws = new Swoole\WebSocket\Server('0.0.0.0', 9502, SWOOLE_PROCESS, SWOOLE_SOCK_TCP | SWOOLE_SSL);
        
        
         $this -> ws->set(
            [
                'ssl_cert_file' => '__DIR__fullchain.pem',//证书位置
                'ssl_key_file' => '__DIR__privkey.pem',//证书位置
                // 'open_http2_protocol' => true,
            ]
        );
        
        //监听WebSocket连接打开事件
        $this -> ws ->on('Open', [$this, "onOpen"]);
        //监听WebSocket消息事件
        $this -> ws->on('Message', [$this, "onMessage"]);
        
        //监听WebSocket连接关闭事件
        $this -> ws->on('Close', [$this, "onClose"]);
        
        $this -> ws->start();
    }
    
    public function onOpen($ws, $request){
        var_dump($request->fd, $request->get, $request->server);
        $ws->push($request->fd, "欢迎客户端： {$request -> fd}\n");
    }
    
    public function onMessage($ws, $frame){
        echo "信息: {$frame->data}\n";
        foreach ($ws -> connections as $fd){
          if($fd == $frame -> fd){
              $ws->push($fd, "我: {$frame->data}");  
          }else {
              $ws->push($fd, "对方: {$frame->data}");  
          }
        }
    }
    
    public function onClose($ws, $fd){
        echo "客户端：{$fd} 关闭\n";
    }
}

new WebSocket();

2：创建客户端文件demo.php

<!doctype html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport"
          content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    <title>Document</title>
</head>
<body>
    <div id="welcome"></div>
    <div>
        <input type="text" id="input" />
        <input type="button" onclick="send()" value="发送"/>
    </div>
    <div id="message"></div>
    <script src="./jquery.js"></script>
    <script>
        var wsServer = "wss://url:9502";//域名加端口
        var websocket = new WebSocket(wsServer);
        console.log(websocket);
        websocket.onopen = function (res) {
            
            $("#welcome").append(
                "<h1>链接成功，欢迎！</h1>"
            );
        };
        
        websocket.onclose = function (res) {
            $("#message").append(
                "<h3>链接关闭</h3>"
            );
        };
        
        websocket.onmessage = function (res) {
            $("#message").append(
                "<h3>" + res.data + "<h3>"
            );
        };

        websocket.onerror = function (res, e) {
            $("#message").append(
                "<h3>" + res.data + "<h3>"
            );
        };
        function send(){
            websocket.send($("#input").val());
        }
    </script>
</body>
</html>

3：启动服务php WebSocket.php

最后再补充端口一定要开启
