Laravel 8 - 未找到外观类

Question

I have been struggling with this after trying to replicate simple tutorials to get started a new project.

Folllowing the tutorials here: https://medium.com/@cmanish049/creating-custom-facades-in-laravel-b9b72d573752

1. Created The Helper Function

    namespace App\\CSVUtils; class CSVParser { public function sayHello() { echo "Hello, from Facade class."; } }

2. Created The Service Provider

   <?php namespace App\\Providers; use Illuminate\\Support\\ServiceProvider; use App\\CSVUtils\\CSVParser; class CsvParserServiceProvider extends ServiceProvider { /** * Register services. * * @return void */ public function register() { $this->app->bind('csvparser',function(){ return new CSVParser(); }); } /** * Bootstrap services. * * @return void */ public function boot() { $this->app->bind('csvparser',function(){ return new CSVParser(); }); } }

3. Created the Facade

   <? namespace App\\CSVUtils; use Illuminate\\Support\\Facades\\Facade; class CSVParserFacade extends Facade { protected static function getFacadeAccessor() { return 'csvparser'; } }

4. Added the following to the app/config.php (I did not remove any of the default entries just added the following

   'providers' => [ App\\Providers\\CsvParserServiceProvider::class, ... ], 'aliases' => [ 'CSV' => App\\CSVUtiles\\CSVParserFacade::class, ... ]

5. Called the Alias in the my controller

   <?php use Illuminate\\Support\\Facades\\Route; Route::get('/csv', function () { CSV::sayHello(); //return view('welcome'); });

RESULT:

ErrorException Class "App\\CSVUtiles\\CSVParserFacade" not found http://localhost/csv

Illuminate\\Foundation\\Bootstrap\\HandleExceptions::handleError vendor/laravel/framework/src/Illuminate/Foundation/AliasLoader.php:80

I have tried a bunch of things, renaming classes / files changing the namespace, calling the Facade directly (rather than from the alias)

I have also tried the following:

composer dump-autoload php artisan config:clear php artisan cache:clear php artisan clear-compiled

And now I feel like I'm loosing my mind. It's been a busy day and my brain is fried but I'm hoping I am missing something simple.

Please help!! :)

Answer 1

Update below code - aliases for CSV :

'providers' => [
     App\Providers\CsvParserServiceProvider::class,
     ...
   ],

 'aliases' => [

     'CSV' => App\CSVUtils\CSVParserFacade::class,

     ...
 ]

Answer 2

Just a little spelling mistake. Correct the spelling in app.php aliases array.

Use this line of code

'CSV' => App\\CSVUtils\\CSVParserFacade::class,
