Laravel BroadcastAs 中的 Pusher 传递参数

Question

嗨，我有这个 js 代码

var pusher = new Pusher('my pusher key', {
        cluster: 'ap2'
    });
    var channel = pusher.subscribe('my-channel');

    channel.bind('my-event', function(data)
    {
        console.log(data);
    });

这是我的 Laravel 代码

protected $pos_invoice;
public function __construct($pos_invoice)
{
    $this->pos_invoice = $pos_invoice;
}
public function broadcastOn()
{
    return new Channel('my-channel');
}

public function broadcastAs()
{
    return 'my-event';
}

这是调用代码

return event( new \App\Events\New_pos_online_order_event('aa'));

现在是代码

channel.bind('my-event', function(data)
    {
        console.log(data);
    });

总是在控制台上返回[]，所以我尝试了这个

public function broadcastAs()
{
    return 'my-event.'.$this->pos_invoice;
}

还有这个

public function broadcastOn()
{
    return new Channel('my-channel'.'asdfasdf');
}

当我更改任何内容时

public function broadcastOn()
{
    return 'my-channel';
}

public function broadcastAs()
{
    return 'my-event';
}

代码不起作用并且在控制台上没有返回任何内容 那么我如何使用 js 在 Pusher 和 Laravel 上传递参数 谢谢..

Answer 1

您需要定义函数broadcastWith

**
 * Get the data to broadcast.
 *
 * @return array
 */
public function broadcastWith()
{
    return ['pos_invoice' => $this->pos_invoice];
}

您将在绑定函数的数据中收到数组
