使用事件触发

执行 php artisan event:generate 并没有生成对应的Listeners下的SendEmailRegister文件 然后这个错误是怎么意思呢

[Symfony\Component\Console\Exception\LogicException]
An option with shortcut “q” already exists.

<?php

namespace App;
//use App\Events\User;
use App\Events\UserRegistered;
use Illuminate\Foundation\Auth\User as Authenticatable;

class User extends Authenticatable
{
    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'name', 'email', 'password',
    ];

    /**
     * The attributes excluded from the model's JSON form.
     *
     * @var array
     */
    protected $hidden = [
        'password', 'remember_token',
    ];

    public static function register(array $attributes)
    {
        $user = static::create($attributes);
        event(new UserRegistered($user));
        return $user;
    }
}

ErrorException in UserRegistered.php line 18: Argument 1 passed to App\Events\UserRegistered::__construct() must be an instance of App\Events\User, instance of App\User given, called in /Users/fanqiang/PHP/www/laravel/laravist/user-signup/app/User.php on line 31 and defined

怎么 发表一次 出来这么多?

laravel的事件触发 和 队列在处理视频中需求，效果不是一样的吗？都是解耦，有什么其他的不同吗？

把一些逻辑放到Model里面然后Model就变得很臃肿了…

为什么在监听器中使用Mail要注入进来而不是直接Mail:send()呢？
