• Swoole跟thinkphp5结合开发WebSocket在线聊天通讯系统教程


    https://cloud.tencent.com/developer/article/1408530

    ThinkPHP使用Swoole需要安装 think-swoole Composer包,前提系统已经安装好了Swoole PECL 拓展

    tp5的项目根目录下执行composer命令安装think-swoole:

    composer require topthink/think-swoole

    话不多说,直接上代码:

    新建WebSocket.php控制器:

    (监听端口要确认服务器放行,宝塔环境还需要添加安全组规则)

    <?php
     
    namespace apphomecontroller;
    use thinkswooleServer;
    class WebSocket extends Server
    {
        protected $host = '0.0.0.0'; //监听所有地址
        protected $port = 9501; //监听9501端口
        protected $serverType = 'socket';
        protected $option = [ 
            'worker_num'=> 4, //设置启动的Worker进程数
            'daemonize'    => false, //守护进程化(上线改为true)
            'backlog'    => 128, //Listen队列长度
            'dispatch_mode' => 2, //固定模式,保证同一个连接发来的数据只会被同一个worker处理
     
            //心跳检测:每60秒遍历所有连接,强制关闭10分钟内没有向服务器发送任何数据的连接
            'heartbeat_check_interval' => 60,
            'heartbeat_idle_time' => 600
        ];
     
        //建立连接时回调函数
        public function onOpen($server,$req)
        {
            $fd = $req->fd;//客户端标识
            $uid = $req->get['uid'];//客户端传递的用户id
            $token = $req->get['token'];//客户端传递的用户登录token
            
            //省略token验证逻辑......
            if (!$token) {
                $arr = array('status'=>2,'message'=>'token已过期');
                $server->push($fd, json_encode($arr));
                $server->close($fd);
                return;
            }
            //省略给用户绑定fd逻辑......
            echo "用户{$uid}建立了连接,标识为{$fd}
    ";
        }
     
        //接收数据时回调函数
        public function onMessage($server,$frame)
        {
            $fd = $frame->fd;
            $message = $frame->data;
     
            //省略通过fd查询用户uid逻辑......
            $uid = 666;
            $data['uid'] = $uid;
            $data['message'] = '用户'.$uid.'发送了:'.$message;
            $data['post_time'] = date("m/d H:i",time());
            $arr = array('status'=>1,'message'=>'success','data'=>$data);
     
            //仅推送给当前连接用户
            //$server->push($fd, json_encode($arr));
            
            //推送给全部连接用户
            foreach($server->connections as $fd) {
                $server->push($fd, json_encode($arr));
            } 
        }
     
        //连接关闭时回调函数
        public function onClose($server,$fd)
        {
            echo "标识{$fd}关闭了连接
    ";
        }
    }

                    }
                }
            });
        }else{
            layer.alert("您的浏览器不支持 WebSocket!");
        }
    });
    </script>

    服务器移到项目根目录开启服务:

    php public/index.php Websocket/start

    这里的路径,是因为我绑定了home模块为默认模块,tp5默认情况是:php public/index.php index/Websocket/start)

    开启成功,查看端口已经被监听:

    lsof -i:9501

    演示效果如下:
