在 Laravel 中安装 Dompdf 后出现 PHP 错误

Question

我运行了这个:

composer require barryvdh/laravel-dompdf

然后我在bootstrap/app.php中注册:

$app->register(\Barryvdh\DomPDF\ServiceProvider::class);

然后我尝试发布:

php artisanvendor:publish --provider="Barryvdh\DomPDF\ServiceProvider"。

然后我遇到了一个大错误，如下所示:

PHP Fatal error:  Uncaught ReflectionException: Class config does not exist in G:\web development  all classes\simba2\vendor\laravel\framework\src\Illuminate\Container\Container.php:809
Stack trace:

现在，当我尝试运行 php artisan ser this 时，它显示了同样的错误。

我认为在 bootstrap/app.php 中注册 laravel-dompdf 是为了 lumen 而不是为了 laravel .

您需要做的是:

1. 首先从您的 bootstrap/app.app 中删除此行 $app->register(\Barryvdh\DomPDF\ServiceProvider::class); 。 php

2. 打开 config/app.php 文件并将 DomPDF 服务提供者合并到提供者数组中，并将 DomPDF 外观合并到别名数组中像这样:

   • 添加 Barryvdh\DomPDF\ServiceProvider::class, 到 providers 数组，如下所示:

     'providers' => [
     /*
     * Laravel Framework Service Providers...
     */
     Illuminate\Auth\AuthServiceProvider::class,
     Illuminate\Broadcasting\BroadcastServiceProvider::class,
     Illuminate\Bus\BusServiceProvider::class,
     Illuminate\Cache\CacheServiceProvider::class,
     ...
     
     /*
     * Package Service Providers...
     */
     Barryvdh\DomPDF\ServiceProvider::class, // added here 
     
     /*
     * Application Service Providers...
     */
     App\Providers\AppServiceProvider::class,
     App\Providers\AuthServiceProvider::class,
     ...
     ],
     

   • 添加 'PDF' => Barryvdh\DomPDF\Facade::class, 到 aliases 数组，如下所示:

      'aliases' => [
     
         'App' => Illuminate\Support\Facades\App::class,
         'Arr' => Illuminate\Support\Arr::class,
         'Artisan' => Illuminate\Support\Facades\Artisan::class,
         ...
         ...
         'PDF' => Barryvdh\DomPDF\Facade::class,
     
         ],
     

   • 保存您的config/app.php

3. 最后执行以下命令以发布来自供应商的 Assets 。

   php artisan vendor:publish --provider="Barryvdh\DomPDF\ServiceProvider"
   

这应该可以解决您的问题

您可以开始使用laravel-dompdf:

use PDF;
