Laravel 8 ERROR :Target class [App\Http\Controllers\App\Http\Controllers\PostController] does-CodePudding

I am new in laravel 8, I add new Controller and edit web.php but still have this error:'Target class [App\Http\Controllers\App\Http\Controllers\PostController] does not exist'

this is PostController.php

<?php

namespace app\Http\Controllers;


class PostController extends Controller
{
    public function index()
    {
        return view('articles');
    }

}

web.php

<?php

use Illuminate\Support\Facades\Route;
use App\Http\Controllers\PostController;

Route::get('/','App\Http\Controllers\PostController@index' );

i also tried the other solution by adding namespace but doesnt work

$namespace = 'App\Http\Controllers';

it give me this error: "Class 'app\Http\Controllers\Controller' not found"

if anyone here can explain to me where is the problem I will be thankful

CodePudding user response：

just convert this to this code

<?php

use Illuminate\Support\Facades\Route;
use App\Http\Controllers\PostController;

Route::get('/','App\Http\Controllers\PostController@index' );

By this one :

enter code here

<?php

use Illuminate\Support\Facades\Route;
use App\Http\Controllers\PostController;

Route::get('/',[PostController::class, 'index']);

the error is you have written a laravel 7 , 6,etc code so the new routes in laravel 8 is like this [NameOfController::class,'name_of_method'] , you can take a look at laravel 8 docs https://laravel.com/docs/8.x/routing

CodePudding user response：

This is happing because default namespace is removed from laravel 8. You should enable from your RouteServiceProvider like below by uncommenting line

 /**
     * The path to the "home" route for your application.
     *
     * This is used by Laravel authentication to redirect users after login.
     *
     * @var string
     */
    public const HOME = '/backend/dashboard';

    /**
     * The controller namespace for the application.
     *
     * When present, controller route declarations will automatically be prefixed with this namespace.
     *
     * @var string|null
     */
    protected $namespace = 'App\\Http\\Controllers'; //uncomment this
