Laravel 事件中的 broadcastOn() 方法从不触发

Question

我是 laravel 和 websockets 的新手。我已经让我的 websockets 在 laravel-websockets 仪表板上工作，现在我试图用这个 javascript 命令触发一个 websocket 事件：

axios.post('updatequeue', {queue_position: newPos});

newPos 是一个数字。

这是我的控制器方法：

public function updateQueue(Request $request){
        $queueposition = $request->input('queue_position');
        event(new QueueUpdate($queueposition));
}

这是我的活动：

class QueueUpdate implements ShouldBroadcast
{
    use Dispatchable, InteractsWithSockets, SerializesModels;

    public $queue_position;

    /**
     * Create a new event instance.
     *
     * @return void
     */
    public function __construct($queue_position)
    {
        $this->queue_position = $queue_position;

    }

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

当我在仪表板中查看事件时，没有任何显示。我从 axios 请求中得到 200 响应。我在整个过程中都放置了日志，并且调用了我的事件 __construct 方法，但没有调用 broadcastOn()。我真的被困在这里，如果有人有任何想法，我将不胜感激。

这是我的 broadcasting.php:

<?php

return [

    'default' => env('BROADCAST_DRIVER', 'null'),

    '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'),
                'host'          => env('WEBSOCKET_BROADCAST_HOST'),
                'port'          => env('WEBSOCKET_BROADCAST_PORT'),
                'scheme'        => env('WEBSOCKET_SCHEME'),
                'encrypted'     => env('WEBSOCKET_ENCRYPTED'),
            ],
        ],

        'redis' => [
            'driver' => 'redis',
            'connection' => 'default',
        ],

        'log' => [
            'driver' => 'log',
        ],

        'null' => [
            'driver' => 'null',
        ],

    ],

];

和websockets.php：

<?php

use BeyondCode\LaravelWebSockets\Dashboard\Http\Middleware\Authorize;

return [


    'dashboard' => [
        'port' => env('LARAVEL_WEBSOCKETS_PORT', 6001),
    ],

    'apps' => [
        [
            'id' => env('PUSHER_APP_ID'),
            'name' => env('APP_NAME'),
            'key' => env('PUSHER_APP_KEY'),
            'secret' => env('PUSHER_APP_SECRET'),
            'enable_client_messages' => false,
            'enable_statistics' => true,
        ],
    ],

    'app_provider' => BeyondCode\LaravelWebSockets\Apps\ConfigAppProvider::class,


    'allowed_origins' => [
        //
    ],

    'max_request_size_in_kb' => 250,

    'path' => 'laravel-websockets',

    'middleware' => [
        'web',
        Authorize::class,
    ],

    'statistics' => [

        'model' => \BeyondCode\LaravelWebSockets\Statistics\Models\WebSocketsStatisticsEntry::class,

        'interval_in_seconds' => 60,


        'delete_statistics_older_than_days' => 60,

        'perform_dns_lookup' => false,
    ],


    'ssl' => [

        'local_cert' => env('LARAVEL_WEBSOCKETS_SSL_LOCAL_CERT', null),

        'local_pk' => env('LARAVEL_WEBSOCKETS_SSL_LOCAL_PK', null),

        'passphrase' => env('LARAVEL_WEBSOCKETS_SSL_PASSPHRASE', null),

        'verify_peer' => env('LARAVEL_WEBSOCKETS_SSL_VERIFY_PEER', true),
    ],


    'channel_manager' => \BeyondCode\LaravelWebSockets\WebSockets\Channels\ChannelManagers\ArrayChannelManager::class,
];

我是本地人。以下是 broadcasting.php 的值：

'driver' => 'pusher',
            'key' => portalkey,
            'secret' => secret,
            'app_id' => portalID,
                'cluster'       => portalcluster,
                'host'          => 127.0.0.1,
                'port'          => 6001,
                'scheme'        => http,
                'encrypted'     => false,

Answer 1

如果您可以连接到 laravel-websockets 仪表板但事件不会显示，可能是您的 /laravel-websockets/auth 请求因 csrf 令牌而失败。尝试将 laravel-websockets 添加到 VerifyCsrfToken 中间件中的 $except 变量。

Answer 2

您应该在 .env 文件中设置 QUEUE_CONNECTION=sync。

这将使广播正常工作并解决您的问题。
