Laravel MailEclipse包报错：ChangeEmailRequest构造函数参数不足

Bug描述 #

Too few arguments to function App\Mail\ChangeEmailRequest::__construct(), 0 passed in D:\Laravel\grand\grandcalendar-api\vendor\qoraiche\laravel-mail-editor\src\MailEclipse.php on line 796 and exactly 2 expected

基于已有邮件类安装MailEclipse包后，访问对应页面触发此错误。

复现步骤 #

• 安装应用
• 访问 /maileclipse/mailables
• 触发报错

问题分析与解决 #

原ChangeEmailRequest邮件类的构造函数要求必须传入2个参数：

<?php

namespace App\Mail;

use App\Models\User;
use Illuminate\Bus\Queueable;
use Illuminate\Mail\Mailable;
use Illuminate\Mail\Mailables\Content;
use Illuminate\Queue\SerializesModels;
use Illuminate\Mail\Mailables\Envelope;
use Illuminate\Contracts\Queue\ShouldQueue;

class ChangeEmailRequest extends Mailable
{
    use Queueable, SerializesModels;

    public $otp;
    public $userName;

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

    // 其余方法省略
}

MailEclipse包在加载邮件类时会无参实例化该类，导致参数缺失报错。为构造函数参数添加默认值null即可解决问题：

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