Laravel 9 Undefined class 'MainController' once uncommented controller namespace in RouteS-CodePudding

I have a fresh installation of Laravel 9 and I tried to uncomment controller namespace in RouteServiceProvider.php. But in my api routes throw an error:

Undefined class 'MainController'

My controller is correctly placed under this namespace.

App\Http\Controllers

api.php file is like this.

Route::group(['prefix' => '/main'], function () {
Route::get('/', [MainController::class, 'index']);
});

Controller file is like this.

<?php

namespace App\Http\Controllers;

class MainController extends Controller
{
  public function index()
  {
    return response()->json(['status'=>200,'message'=>'success']);
  }
}

If I import the controller file to api routes file, it works as normal.

CodePudding user response：

use this in route file web.php

use App\Http\Controllers\MainController;

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

CodePudding user response：

You have to add full path of use controller in route file like these

use App\Http\Controllers\MainController;

And also use full path when we declare a route...

Route::get('/', [App\Http\Controllers\MainController::class, 'index']); });
