如何在Laravel 5.3中传递Request数据到Mailable - how to pass Request data into Mailable in Laravel 5.3

我无法理解如何使用Laravel 5.3的新Mailable特性将Request数据传递给邮件使用下面的代码，我得到了错误，变量$request没有定义。

web.php

Route::get('/',                 ['as' => 'home',        'uses' => 'HomeController@index']);
Route::get('/callback',         ['as' => 'callback.show',   'uses' => 'PostController@callbackshow']);
Route::post('/callback',        ['as' => 'callback.send',   'uses' => 'PostController@callbacksend']);

控制器' PostController.php

<?php namespace App'Http'Controllers;
use App'Mail'Callback;
use Illuminate'Http'Request;

class PostController extends Controller {

    public function __construct()
    {
    }
    public function callbackshow() 
    {
        return view('callback');   
    }
    public function callbacksend(Request $request) 
    {
        $email = new Callback($request);
        'Mail::to('test@gmail.com')->send($email);
    }

邮件' Callback.php

namespace App'Mail;
use Illuminate'Http'Request;
use Illuminate'Bus'Queueable;
use Illuminate'Mail'Mailable;
use Illuminate'Queue'SerializesModels;
use Illuminate'Contracts'Queue'ShouldQueue;
class Callback extends Mailable
{
    use Queueable, SerializesModels;
    public function __construct(Request $request)
    {
        $this->request = $request->all();
    }
    public function build()
    {
        return $this->view('emails.callback');
    }
}

邮件' callback.blade.php

Name: {{ $request->name }}<br>
Email :  {{ $request->email }}<br>

这里是错误

Whoops, looks like something went wrong.

我是这样解决这个问题的

namespace App'Mail;
use Illuminate'Http'Request;
use Illuminate'Bus'Queueable;
use Illuminate'Mail'Mailable;
use Illuminate'Queue'SerializesModels;
use Illuminate'Contracts'Queue'ShouldQueue;
class Callback extends Mailable
{
    use Queueable, SerializesModels;
    public $input;

    public function __construct(Request $request)
    {
        $this->input = $request->all();
        if (empty($this->input['email'])) { $this->input['email'] = 'admin@site.ru'; }
    }

    public function build()
    {
            return $this->subject('Обратный звонок с сайта')
                        ->view('emails.callback')
                        ->cc($this->input['email'], $this->input['name'])
                        ->replyTo($this->input['email'], $this->input['name']);
    }
}
