推送器：JSON 返回空字符串

Question

我正在尝试使用 Pusher 和 Laravel-Echo 在 Laravel 中制作实时通知系统。所以在 Vue 文件中，当我连接到私人频道时，从 auth 端点返回的 JSON 是空字符串。

这是我的代码。

config/auth.php

<?php

return [

    /*
    |--------------------------------------------------------------------------
    | Authentication Defaults
    |--------------------------------------------------------------------------
    |
    | This option controls the default authentication "guard" and password
    | reset options for your application. You may change these defaults
    | as required, but they're a perfect start for most applications.
    |
    */

    'defaults' => [
        'guard' => 'web',
        'passwords' => 'users',
    ],

    /*
    |--------------------------------------------------------------------------
    | Authentication Guards
    |--------------------------------------------------------------------------
    |
    | Next, you may define every authentication guard for your application.
    | Of course, a great default configuration has been defined for you
    | here which uses session storage and the Eloquent user provider.
    |
    | All authentication drivers have a user provider. This defines how the
    | users are actually retrieved out of your database or other storage
    | mechanisms used by this application to persist your user's data.
    |
    | Supported: "session", "token"
    |
    */

    'guards' => [
        'web' => [
            'driver' => 'session',
            'provider' => 'users',
        ],
        'teacher' => [
            'driver' => 'session',
            'provider' => 'teacher',
        ],

        'api' => [
            'driver' => 'token',
            'provider' => 'users',
            'hash' => false,
        ],
    ],

    /*
    |--------------------------------------------------------------------------
    | User Providers
    |--------------------------------------------------------------------------
    |
    | All authentication drivers have a user provider. This defines how the
    | users are actually retrieved out of your database or other storage
    | mechanisms used by this application to persist your user's data.
    |
    | If you have multiple user tables or models you may configure multiple
    | sources which represent each model / table. These sources may then
    | be assigned to any extra authentication guards you have defined.
    |
    | Supported: "database", "eloquent"
    |
    */

    'providers' => [
        'users' => [
            'driver' => 'eloquent',
            'model' => App\User::class,
        ],
        'teacher' => [
            'driver' => 'eloquent',
            'model' => App\Teacher::class,
        ],

        // 'users' => [
        //     'driver' => 'database',
        //     'table' => 'users',
        // ],
    ],

    /*
    |--------------------------------------------------------------------------
    | Resetting Passwords
    |--------------------------------------------------------------------------
    |
    | You may specify multiple password reset configurations if you have more
    | than one user table or model in the application and you want to have
    | separate password reset settings based on the specific user types.
    |
    | The expire time is the number of minutes that the reset token should be
    | considered valid. This security feature keeps tokens short-lived so
    | they have less time to be guessed. You may change this as needed.
    |
    */

    'passwords' => [
        'users' => [
            'provider' => 'users',
            'table' => 'password_resets',
            'expire' => 60,
            'throttle' => 60,
        ],
    ],

    /*
    |--------------------------------------------------------------------------
    | Password Confirmation Timeout
    |--------------------------------------------------------------------------
    |
    | Here you may define the amount of seconds before a password confirmation
    | times out and the user is prompted to re-enter their password via the
    | confirmation screen. By default, the timeout lasts for three hours.
    |
    */

    'password_timeout' => 10800,

];

resources/js/bootstrap.js

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: true,    
});

Pusher.logToConsole = true;

vue文件，挂载函数连接私密频道

mounted(){
        window.Echo.private('homeworknotif')
        .listen('HomeworkAdded', e => {
          console.log(e);
        })
      },

家庭作业已添加事件文件

<?php

namespace App\Events;

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 HomeworkAdded implements ShouldBroadcast
{
    use Dispatchable, InteractsWithSockets, SerializesModels;

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

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

routes/channels.php

Broadcast::channel('homeworknotif', function($user, $id){
    return true;
});

在控制器中广播

public function eventer(){
        broadcast(new HomeworkAdded('hello world'));
    }

当我将 window.Echo.private 更改为 window.Echo.channel 时，没有错误，控制台中的日志显示，我已发送数据，但数据仅在日志中可见。

Answer 1

我不敢相信，但我没有在 .env 文件中设置我的 BROADCAST_DRIVER，它是日志而不是推送器。
