服务端（创建一个.php文件）记得把端口号修改一下

server = new swoole_websocket_server(self::HOST,self::PORT);
        $this->redis = new Redis();
        $this->redis->connect('127.0.0.1',6379);
        
        // 方法的调用
        $this->server->on('open',[$this,'onOpen']);
        $this->server->on('message',[$this,'onMessage']);
        $this->server->on('close',[$this,'onClose']);
        $this->server->start();
    }
    public function onOpen($server,$request){
        $userId = $request->get['user_id'];
        $this->redis->set('talk'.$userId,$request->fd);
        $this->userId = $userId;
        echo "用户Id->".$userId.'客户端标识'.$request->fd.'连接成功'.PHP_EOL;
    }
    public function onMessage($server,$frame){
    $data = json_decode($frame->data,true);

    // 心跳检测
    if($data['type'] == 'heart'){
        echo "这是心跳".PHP_EOL;
        return;
    }

    $toFd = $this->redis->get('talk'.$data['toid'])?:null;
    if (empty($toFd)){
        $this->server->push($frame->fd,json_encode([
        'type'=>'server',
        'content'=>'亲,对方暂时不在线,请稍后再试！'
        ]));
        return;
    }
    $this->server->push($toFd,json_encode([
