laravel 5.5 修改auth 重置密码邮件

1.输入 php artisan make:notification RestPassword ，在 app otification 下创建 RestPassword.php

然后修改 AppUser：

namespace App;

use IlluminateNotificationsNotifiable;
use IlluminateFoundationAuthUser as Authenticatable;
use AppNotificationsResetPassword as RestPasswordNotification; // 替换 

class User extends Authenticatable
{
    use Notifiable;

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

    /**
     * The attributes that should be hidden for arrays.
     *
     * @var array
     */
    protected $hidden = [
        'password', 'remember_token',
    ];

    public function sendPasswordResetNotification($token)
    {
        $this->notify(new RestPasswordNotification($token));
    }
}

 2.输入 php artisan vendor:publish --tag=laravel-notifications 

将自动创建 email.blade.php 模版，我这里并不想修改 

3.更改邮件内容，修改第一步创建的 app otificationRestPassword.php  

namespace AppNotifications;

use IlluminateBusQueueable;
use IlluminateNotificationsNotification;
use IlluminateContractsQueueShouldQueue;
use IlluminateNotificationsMessagesMailMessage;

class ResetPassword extends Notification
{
    use Queueable;

    /**
     * The password reset token.
     *
     * @var string
     */
    public $token;

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

    /**
     * Get the notification's delivery channels.
     *
     * @param  mixed  $notifiable
     * @return array
     */
    public function via($notifiable)
    {
        return ['mail'];
    }

    /**
     * Get the mail representation of the notification.
     *
     * @param  mixed  $notifiable
     * @return IlluminateNotificationsMessagesMailMessage
     */
    public function toMail($notifiable)
    {
        return (new MailMessage)
                    ->subject('XXXX')
                    ->salutation('XXX')
                    ->line('您之所以收到这封邮件是因为我们收到了您重置密码的申请。')
                    ->action('Reset Password', url(config('app.url').route('password.reset', $this->token, false)))
                    ->line('如果您本人未进行密码重置，您可以不必采取进一步操作!');
    }

}

沿着 IlluminateNotificationsMessagesMailMessage 可以找到 IlluminateNotificationsMessagesSampleMessage 
其中包含了 subject, salutation ...
