Question

Here is my controller:

Answer 1

in laravel-8 default remove namespace prefix so you can set old way in laravel-7 like:

in RouteServiceProvider.php add this variable

protected $namespace = 'App\Http\Controllers';

and update boot method

public function boot()
{
       $this->configureRateLimiting();

       $this->routes(function () {
            Route::middleware('web')
                ->namespace($this->namespace)
                ->group(base_path('routes/web.php'));

            Route::prefix('api')
                ->middleware('api')
                ->namespace($this->namespace)
                ->group(base_path('routes/api.php'));
        });
}
