使用html+swoole通过websocket实现一个简单的聊天室代码
使用html+swoole通过websocket实现一个简单的聊天室代码。
客户端代码：
<html>
<head>客户端</head>
<body>
<script type="text/javascript">
var sock = null;
var wsuri = "ws://127.0.0.1:1234";
window.onload = function () {
console.log("onload");
sock = new WebSocket(wsuri);
sock.onopen = function () {
console.log("connected to " + wsuri);
}
sock.onclose = function (e) {
console.log("connection closed (" + e.code + ")");
}
sock.onmessage = function (e) {
console.log("message received: " + e.data);
}
};
function send() {
var msg = document.getElementById('message').value;
sock.send(msg);
};
</script>
<h1>WebSocket Echo Test</h1>
<form>
<p>
Message: <input id="message" type="text" value="Hello, world!">
</p>
</form>
<button onclick="send();">Send Message</button>
</body>
</html>
服务端代码：
<?php
$serv = new swoole_websocket_server("127.0.0.1", 9502);
$serv->on('Open', function ($server, $req) {
echo "connection open: " . $req->fd;
});
$serv->on('Message', function ($server, $frame) {
echo "message: " . $frame->data;
$server->push($frame->fd, json_encode(["hello", "world"]));
});
$serv->on('Close', function ($server, $fd) {
echo "connection close: " . $fd;
});
$serv->start();
