Laravel Lumen + Broadcasting + Redis + Class pusher not found

【中文标题】Laravel Lumen + Broadcasting + Redis + Class pusher not found

【问题描述】：

所以我正在尝试使用 redis 设置广播，但是我无法让它工作，因为我想我缺少一些配置选项。

.env 文件

...
BROADCAST_DRIVER=redis
...

控制器

event(new TestEvent());

TestEvent.php

<?php

namespace App\Events\Socket;

use App\Events\Event;
use Illuminate\Broadcasting\PrivateChannel;
use Illuminate\Contracts\Broadcasting\ShouldBroadcast;

class TestEvent implements ShouldBroadcast


    protected $data;

    /**
     * Create a new event instance.
     *
     * @return void
     */
    public function __construct()
    
        $this->data = [
            'payload' => [
                'test' => 'test'
            ],
            'message' => 'another'
        ];
    

    public function broadcastOn()
    

        return new PrivateChannel('user.2');
    

但是，当我在数据库的 failed_jobs 表中运行它时，会弹出此错误：

39 主要

这很奇怪，因为它不应该尝试创建 Pusher 实例。

我试过 composer dump-autoload、composer clear-cache、php artisan clear-compiled...

这很有趣，因为如果我尝试这段代码并转储实例，我会得到一个配置良好的 BroadcastManager：

$broadcastManager = (new BroadcastManager(app()))->connection();

有人可以帮忙吗？

【参考方案1】：

不要告诉你留言后发生了什么，试试看

composer require pusher/pusher-php-server --no-scripts

或

php artisan clear-compiled

或

编辑“vendor/laravel/framework/src/illuminate/Broadcasting/BroadcastManager.php”中的行

"使用推送器；" “使用 Pusher\Pusher;”

或

在您的 config/app.php 中将此行添加到别名

'Pusher' => Pusher\Pusher::class,

【讨论】：

在vendor/composer/autoload_classmap.php 我有'Pusher\\Pusher' => $vendorDir . '/pusher/pusher-php-server/src/Pusher.php', 所以，use Pusher\Pusher 是正确的。为什么我需要添加别名？
