Web伺服器

環境：Centos6.4，PHP環境：PHP7

服務端程式碼

<?php
//建立websocket伺服器
$host = '0.0.0.0';
$port = 9501;
$ws = new swoole_websocket_server($host, $port);

//
$ws->on('open', function($ws, $request){ //$ws就是我們的伺服器，$request就是客戶端的資訊
    var_dump($request);
    $ws->push($request->fd,"welcome \n");
});

$ws->on('message', function($ws, $request){
    echo 'Message:'. $request->data;
    $ws->push($request->fd,'get it message');
});
$ws->on('close', function($ws, $request){
    echo 'close';
});

$ws->start();

客戶端程式碼

<!DOCTYPE html>
<html>
<head>
    <title>WebSecket</title>

<body>
<Script>
var wsServer = 'ws://192.168.9.155:9501';
var websocket = new WebSocket(wsServer);
websocket.onopen = function (evt) {
    console.log("連結成功");
};

websocket.onclose = function (evt) {
    console.log("關閉連結");
};

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>

檔案分別是index4.php、index4.html,。
