Javascript Yii2使用Yii2节点套接字从php向客户端发送事件

我经常在一个混凝土房间里向客户发送事件。我按照所有步骤在我的项目中安装扩展，服务器成功启动，客户端连接到套接字，但当我试图从php代码发送事件时，客户端没有收到任何数据

Javascript代码：

var socket = new YiiNodeSocket();
socket.onConnect(function () {
socket.room('testRoom').join(function (success, numberOfRoomSubscribers) {
    // success - boolean, numberOfRoomSubscribers - number of room members
    // if error occurred then success = false, and numberOfRoomSubscribers - contains error message
    if (success) {
        console.log(numberOfRoomSubscribers + ' clients in room: testRoom');
        // do something

        // bind events
        this.on('join', function (newMembersCount) {
            // fire on client join
        });

        this.on('data', function (data) {
            // fire when server send frame into this room with 'data' event
            console.log('in data : ', data);
        });
    } else {
        // numberOfRoomSubscribers - error message
        alert(numberOfRoomSubscribers);
    }
});
});

PHP代码：

    // create frame
    $frame = Yii::$app->nodeSocket->getFrameFactory()->createEventFrame();

    // set event name
    $frame->setEventName('data');

    // set room name
    $frame->setRoom('testRoom');

    // set data
    $frame['key'] = 'hello';

    // send
    $frame->send();

你有办法吗？
