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
