Laravel邮件视图未返回传递的数据

Question

我正在尝试使用Laravel默认邮件外观发送电子邮件：-

Mail::to($user->email)->send(New NotifyUserExpiring($diff,$Sub->user));

在Mail\NotifyUserExpiring中：-

<?php

namespace App\Mail;

use Illuminate\Bus\Queueable;
use Illuminate\Mail\Mailable;
use Illuminate\Queue\SerializesModels;
use Illuminate\Contracts\Queue\ShouldQueue;

class NotifyUserExpiring extends Mailable
{
    use Queueable, SerializesModels;

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

    /**
     * Build the message.
     *
     * @return $this
     */
    public function build()
    {
        return $this->view('web.mail.NotifyUserExpiring')->with('user',$this->user)->with('diff',$this->diff);
    }
}

在网络上。邮政NotifyUserExpiring视图文件我正在使用刀片打印方式变量：-

Hello {{ $user->first_name }}
Message Here

当我检查我的邮件收件箱时，我收到了一封带有{{$user的电子邮件-

你好{{$user-

<div>
    Hello {{ $user->first_name }}

    Message body test
</div>

确保邮件视图文件名的后缀为。刀身php，以便它通过刀片渲染引擎。
