laravel - 如何使用 laravel 和 pusher api 向特定用户广播事件？

Question

我的问题是向特定用户广播事件。我正在构建一个实时聊天应用程序。所以这有私人聊天和群聊。

在一对一聊天（私人聊天）中，如果一个用户向另一个用户发送消息，则将新消息广播给目标用户，而不是所有用户。目前，向所有用户广播。同上，在群聊中，我希望向群中的成员定向广播。

这是我的代码。

laravel 事件

<?php

namespace App\Events;

use App\Message;
use Illuminate\Broadcasting\Channel;
use Illuminate\Broadcasting\InteractsWithSockets;
use Illuminate\Broadcasting\PresenceChannel;
use Illuminate\Broadcasting\PrivateChannel;
use Illuminate\Contracts\Broadcasting\ShouldBroadcast;
use Illuminate\Foundation\Events\Dispatchable;
use Illuminate\Queue\SerializesModels;

class NewMessage implements ShouldBroadcast
{
    use Dispatchable, InteractsWithSockets, SerializesModels;
    public $message;
    /**
     * Create a new event instance.
     *
     * @return void
     */
    public function __construct($message)
    {
        $this->message = $message;
        // $this->dontBroadcastToCurrentUser();
    }

    /**
     * Get the channels the event should broadcast on.
     *
     * @return \Illuminate\Broadcasting\Channel|array
     */
    public function broadcastOn()
    {
        return new PrivateChannel('chats');
    }
}

渠道

<?php

use Illuminate\Support\Facades\Broadcast;

/*
|--------------------------------------------------------------------------
| Broadcast Channels
|--------------------------------------------------------------------------
|
| Here you may register all of the event broadcasting channels that your
| application supports. The given channel authorization callbacks are
| used to check if an authenticated user can listen to the channel.
|
*/

Broadcast::channel('App.User.{id}', function ($user, $id) {
    return (int) $user->id === (int) $id;
});
Broadcast::channel('chats', function ($user) {
    return auth()->check();
});
