【问题描述】：

我使用的是 laravel 5.8 版本。我正在向推送者发送消息和用户值，但将推送者接收事件 {“消息”：空，“用户”：空}。这是我的 broadcasting.php 文件

 'connections' => [

        'pusher' => [
            'driver' => 'pusher',
            'key' => env('PUSHER_APP_KEY'),
            'secret' => env('PUSHER_APP_SECRET'),
            'app_id' => env('PUSHER_APP_ID'),
            'options' => [
//                'cluster' => env('PUSHER_APP_CLUSTER'),
//                'useTLS' => true,
                'cluster' => 'ap2',
                'useTLS' => true
            ],
        ],

这是我的 chatevent.php 文件。命名空间应用\事件；

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

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

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

还有我的 bootstrap.js 文件。

import Echo from 'laravel-echo';

window.Pusher = require('pusher-js');

window.Echo = new Echo({
    // broadcaster: 'pusher',
    // key: process.env.MIX_PUSHER_APP_KEY,
    // cluster: process.env.MIX_PUSHER_APP_CLUSTER,
    // encrypted: truebroadcaster: 'pusher',
    broadcaster: 'pusher',
        key:'7d64c4828272fba9bbdd',
        cluster: 'ap2',
        encrypted: true
});

我向推送器发送消息和用户的控制器功能。

 public function send()
    {
        $message = 'hello';
        $user = User::find(Auth::id());

        event(new ChatEvent($message, $user));
    }
}

【解决方案1】：

在您的 chatEvent 类中添加有效负载：并且您正在以错误的方式访问数据成员：

 $this->message = $message; //right way

代替：

$this->$message = $message; //wrong way,(remove dollar sign when using $this->)

编写代码如下：您也可以将消息变量替换为有效负载：

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

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

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