Laravel: Not picking up __invoke method?

Question

Trying to use invokable controllers, but it seems to fail to find the __invoke method?

Invalid route action: [App\Http\Controllers\App\Http\Controllers\MainController].

It seems to be returning true on:

if (! method_exists($action, '__invoke')) {
    throw new UnexpectedValueException("Invalid route action: [{$action}].");
}

Routes:

<?php

Route::get('/', \App\Http\Controllers\MainController::class);

MainController:

<?php

namespace App\Http\Controllers;

class MainController extends Controller
{
    public function __invoke()
    {
        dd('main');
    }
}

Answer 1

Laravel by default assumes that your controllers will be located at App\Http\Controllers\. So when you're adding the full path to your controller, Laravel will check it there, at App\Http\Controllers\App\Http\Controllers\MainController.

To solve it simply remove the namespace when you're registering the route, and register it like this:

Route::get('/', MainController::class);

Alternatively, you can stop this behavior by removing ->namespace($this->namespace) from mapWebRoutes() method on RouteServiceProvider class, which is located at App\Providers folder. Then you can register your routes like this:

Route::get('/', \App\Http\Controllers\MainController::class);

The best answer that works for everyone is laravel documentation.

just use this at the top of your route(web.php) if (websiteController is the name of your controller)

use App\Http\Controllers\WebsiteController;

and define your route like this for your index page

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