wss 配置和 nginx的配置

wss swoole 服务端

<?php
error_reporting(E_ALL);
set_time_limit(0);

//创建websocket服务器对象，监听0.0.0.0:9502端口
$ws = new swoole_websocket_server("0.0.0.0", 9505, SWOOLE_PROCESS, SWOOLE_SOCK_TCP | SWOOLE_SSL);
$config = [
        'daemonize' => true,
        'ssl_key_file'  => '/workspace/file/2191282_www.havetatami.com.key',
        'ssl_cert_file' => '/workspace/file/2191282_www.havetatami.com.pem'
];
$ws->set($config);
//监听WebSocket连接打开事件
$ws->on('open', function ($ws, $request) 
        var_dump($request->fd);
        $ws->push($request->fd, "hello, welcome\\n");
);

//监听WebSocket消息事件
$ws->on('message', function ($ws, $frame) 
        var_dump($ws->connection_list());
        foreach ($ws->connection_list() as $fd)
                $ws->push($fd, "server: $frame->data");
        
);

//监听WebSocket连接关闭事件
$ws->on('close', function ($ws, $fd) 
    echo "client-$fd is closed\\n";
);

$ws->start();

wss 浏览器端

<html>
<head>
<meta charset=utf-8 >
<title>test</title>
</head>

<body>

<h3 style="text-align:center;">test</h3>

<script>

var wsServer = 'wss://www.havetatami.com:9502/websocket';
var websocket = new WebSocket(wsServer);

function ssend()
        websocket.send(1);
        setTimeout(ssend, 100);


websocket.onopen = function (evt) 
        console.log("Connected to WebSocket server.");
        //ssend();
;

websocket.onclose = function (evt) 
    console.log("Disconnected");
;

websocket.onmessage = function (evt) 
    console.log('Retrieved data from server: ' + evt.data);
;

websocket.onerror = function (evt, e) 
    console.log('Error occured: ' + evt.data);
;

</script>
</body>
</html>
