弹幕[dàn mù] (barrage),中文流行词语,指的是在网络上观看视频时弹出的评论性字幕。下面我们就来看一下使用workerman实现简单弹幕的方法。

php代码:

<?php  
use Workerman\Worker;  
require_once '../Autoloader.php';//注意 这里要看你的workerman里的这个文件在哪 然后在进行修改  
  
$global_uid = 0;  
  
// 当客户端连上来时分配uid,并保存连接,并通知所有客户端  
function handle_connection($connection) {  
    global $text_worker, $global_uid;  
    // 为这个链接分配一个uid  
    $connection->uid = ++$global_uid;  
    foreach ($text_worker->connections as $conn) {  
        $conn->send("user[{$connection->uid}] online");  
    }  
}  
  
// 当客户端发送消息过来时,转发给所有人  
function handle_message($connection, $data) {  
    global $text_worker;  
    foreach ($text_worker->connections as $conn) {  
        $conn->send("user[{$connection->uid}] said: $data");  
    }  
}  
  
// 当客户端断开时,广播给所有客户端  
function handle_close($connection) {  
    global $text_worker;  
    foreach ($text_worker->connections as $conn) {  
        $conn->send("user[{$connection->uid}] logout");  
    }  
}  
  
$text_worker = new Worker("websocket://0.0.0.0:2347");  
  
$text_worker->count = 1;  
  
$text_worker->onConnect = 'handle_connection';  
$text_worker->onMessage = 'handle_message';  
$text_worker->onClose = 'handle_close';  
  
Worker::runAll();

HTML代码:

<!DOCTYPE html>  

<html>  
<head>  
    <meta charset="UTF-8">  
    <title>Simple Chat</title>  
</head>  
<body>  
    <center> 
<h1>Simple Chat</h1>  
<input type="text" id="msg">  
<button type="button" id="send">send</button> 


<div id="content" style="width:200px;height:200px;border:1px solid red">
    假装在播放视频
    <marquee behavior="" direction=""></marquee>
</div>  
</center>
</body>  
  
<script type="text/javascript">  
    window.onload = function () {  
        var ws = new WebSocket("ws://127.0.0.1:2347");  
  
        document.getElementById("send").onclick = function () {  
            var msg = document.getElementById("msg").value;  
            ws.send(msg);  
        };  
  
        ws.onopen = function () {  
            console.log("连接成功");  
//            ws.send('raid');  
        };  
        ws.onmessage = function (e) {  
            document.getElementById("content").innerHTML += '<marquee behavior="" direction="">' + e.data + '</marquee>';  
        };  
    };  
</script>  
  
</html>
