Thinkphp 使用Workerman 聊天室_thinkphp workerman

1、下载Workerman插件

composer require topthink/think-worker

2、示例代码 后端

     2.1 下载之后会得到这俩个文件 

2.2 这个文件对应上面的worker_class 的地址 

   2.3.worker.php示例代码

<?php
namespace app\http;
use think\facade\Db;
use think\worker\Server;
use Workerman\Lib\Timer;
use app\model\IndexModel;
/**
 * websockect
 * Class Worker
 * @package app\http
 */
class Worker extends Server
{
    protected $socket = 'http://0.0.0.0:2348';
    /**
     * 心跳检测
     * @var int
     */
    protected static $heartbeat_time    =   55;
 
    public function onConnect($connection){
        var_dump('connect success');
        $connection->send(json_encode('connect success'));
    }
 
    ## 接收消息，接收心跳消息 ,接收用户id 信息等等
    public function onMessage($connection,$data)
    {
        $connection->lastMessageTime = time();
        #var_dump($data);
        $connection->send(json_encode('receive success'));
    }
 
    /**
     * 消息回调
     * @param $worker
     * @author 冬
     * @date 2022/5/5 17:07
     */
    public function onWorkerStart($worker)
    {
        //查看是否有新的下面的3是几秒推送一次
        Timer::add(3, function () use ($worker) {
 
            $time_now           = time();
            var_dump(date('Y-m-d H:i:s',$time_now) );
            ## 推送的数据
            $infoObj =  IndexModel::getTips();
 
            $infoArr = json_decode(json_encode($infoObj),true);
 
            if (true) {
 
                foreach ($worker->connections as $connection) {
                    if (empty($connection->lastMessageTime)) {
                        $connection->lastMessageTime = $time_now;
                    }
 
                    var_dump(date('Y-m-d H:i:s',$connection->lastMessageTime) );
                    if ($time_now - $connection->lastMessageTime > self::$heartbeat_time) {
                        $connection->close();
                    }
 
                    $connection->send(json_encode($infoArr));
                }
 
            } else {
                var_dump(22);
                foreach ($worker->connections as $connection) {
                    if (empty($connection->lastMessageTime)) {
                        $connection->lastMessageTime = $time_now;
                        continue;
                    }
 
                    if ($time_now - $connection->lastMessageTime > self::$heartbeat_time) {      //连接超时
                        $connection->close();
                    }
                }
            }
        });
    }
 
    public function onClose($connection){
        var_dump('close');
    }
 
 
 
}

     2.4 前端示例代码

 
<script>
let ws = new WebSocket("ws://127.0.0.1:2348")
 
ws.onopen = function() {  //绑定连接事件
    console.log("连接成功");
    //每30秒发送一次心跳
    setInterval(function(){
        ws.send(JSON.stringify({'type':"peng"}));
        console.log('发送心跳...');
 
    },30000)
 
};
 
ws.onmessage = function(evt) {//绑定收到消息事件
    data = JSON.parse(evt.data)
    console.log(data);
    //这里处理收到的消息, type类型有两种: connectin、deposit如果有deposit要提示
 
};
 
 
ws.onclose = function(evt) { //绑定关闭或断开连接事件
　　console.log("连接已关闭");
};
 
</script>

3、开启服务 php think worker:server

4、打开前端页面查看是否链接成功
