Question

尝试在laravel中的/public/assets/others/brochure/jan-2016.pdf路由中查看存储在brochure/jan-2016.pdf', 'BrochureController@show');文件中的pdf。

但我收到的错误为：Whoops, looks like something went wrong

路线代码：

Route::get('/brochure/{file}', 'BrochureController@show');

在控制器中：

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use App\Http\Requests;
use App\Http\Controllers\Controller;

class BrochureController extends Controller
{   
    public function show($filename)
    {       
        $filename = 'jan-2016.pdf';
        $filepath = 'assets/others/brochure/';
        $path = $filepath.$filename;

        return Response::make(file_get_contents($path), 200, [
        'Content-Type' => 'application/pdf',
        'Content-Disposition' => 'inline; '.$filename,
        ]);
    }
}

当我尝试仅打印文件内容时，它会捕获文件并使用file_get_contents($path)以某种奇怪的方式显示

输出： %PDF-1.4 %�� 1 0 obj <>stream PScript5.dll Version 5.2.2 GVTP January 2016 Dummy content endstream endobj 2 0 obj <> endobj 4 0 obj <> endobj 3 0 obj <> endobj 5 0 obj <>/Rotate 90/Parent 3 0 R/MediaBox[0 0 595 842]/Contents 11 0 R/Type/Page>> endobj 11 0 obj <>stream x��]Ys�u.;��8Ξ��d��z_�'�Z��Iت�� $��_��oN�L�9=sw@��-...

这意味着它从确切的路径中选择文件。我认为有一位读者可以将其作为第三方服务来处理，例如：Adobe pdf阅读器。

我做错了什么？

Answer 1

这是代码

$filename = 'assets/others/129778.pdf';
$path = storage_path().DIRECTORY_SEPARATOR.$filename;

return Response::make($path, 200, [
'Content-Type' => 'application/pdf',
'Content-Disposition' => 'inline; '.$filename,
]);

看看它是否有效并且知道了吗？

Answer 2

在BrochureController.php中

public function show($filename)
{
    $file = base_path(). "/public/assets/others/brochure/". $filename;

    $name = "Human Name For File.pdf";

    $headers = ['Content-Type: application/pdf'];

    return Response::download($file, $name, $headers);
}

现在在您的应用中访问http://example.com/brochure/jan-2016.pdf并下载jan-2016.pdf文件。

如果您不希望用户能够猜到他们也可以访问http://example.com/assets/others/jan-2016.pdf那么您可以将PDF移动到另一个目录（例如/resources/brochures）可公开访问，然后您可以将方法的第一行更改为：

$file = base_path(). "/resources/brochures/". $filename;

这意味着每个人都必须转到http://example.com/brochure/jan-2016.pdf才能访问该文件。

Answer 3

你可以使用这个包[barryvdh / laravel-dompdf] [1]。并使用如下：这只是示例snippset

class BrochureController extends Controller
{   
    public function show($filename)
    {       
        $html = 'Your content in PDF';    

        $pdf = PDF::loadHTML($html);

        //set the name of the pdf document
        $file_name = 'jan-2016.pdf';

        //check if the path exist or not
        if(!File::exists(storage_path() . '/pdf')) {

             $result = File::makeDirectory(storage_path() . '/pdf');
        }

        $pdf->save(storage_path() . '/pdf/' . $file_name);

        //return $file_name;

        return $pdf->download($file_name);

    }
}

Answer 4

考虑报价合同示例

控制器：

<?php

namespace App\Http\Controllers;
use Illuminate\Support\Facades\File;
use Illuminate\Support\Facades\Response;

class OfferController extends Controller
{
    public function index()
    {
        $file = public_path().DIRECTORY_SEPARATOR.'media'.DIRECTORY_SEPARATOR.'offer.pdf';
        $file = File::get($file);
        $response = Response::make($file,200);
        $response->header('Content-Type', 'application/pdf');
        return $response;
    }
}

路线：

Route::get('/offer','OfferController@index')->name('offer');

优点：

https://name.site/offer
