使用Barryvdh\DomPDF\Facade预览pdf而不是下载

Question

我正在使用Barryvdh\DomPDF\在我的laravel项目中生成pdf文件，这是我的控制器：

<?php
// Our Controller
namespace App\Http\Controllers;

use Illuminate\Http\Request;
// This is important to add here.
use Barryvdh\DomPDF\Facade as PDF;

class CustomerController extends Controller
{
    public function printPDF()
    {
        // This  $data array will be passed to our PDF blade
        $data = [
            'title' => 'First PDF for Medium',
            'heading' => 'Hello from 99Points.info',
            'content' => 'Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industrys standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged.'
            ];

        $pdf = PDF::loadView('pdf_view', $data);
        return $pdf->download('medium.pdf');
    }
}

如何在浏览器中预览我的pdf结果而不是下载？

谢谢

将返回更改为包含文件和标头上的文件MIME类型的响应

$pdf = PDF::loadView('pdf_view', $data)->download('medium.pdf');

return response($pdf, 200)
            ->header('Content-Type', File::mimeType($pdf));
