Work on API project. Everything good until I have to add a new endpoint (new method too) and I got this Error for my new endpoint, another endpoint run well. Below is error log:

My routes for new endpoint:

$app->get('/user/notification', 'UserController:getNotification');

My class:

class UserController{
    public function __construct($container)
    {
        // make the container available in the class
        $this->container = $container;
    }

    public function getNotification($request, $response, $args){
        //my code here
    }
}

my dependencies.php:

use App\Controllers\UserController;
$container = $app->getContainer();
$container['UserController'] = function ($c) {
    return new UserController($c);
};

my composer.json

{
    "name": "slim/slim-skeleton",
    "autoload": {
        "psr-4": {
           "App\\": "src/"
        }
    }
}

tried to composer dump-autoload but that did not work.

回答1:

PHP cannot find your class.

require it in the index.php
Fix your PSR-0/4 autoload schema and then dump-autoload

回答2:

Not carefully when rsync to the server. I uploaded to wrong dir Controller instead Controllers.

回答3:

I had a similar issue and I get there. In my case, Slim couldn't instanciate the Controller class because it was simply misspelled.

回答4:

'UserController:getNotification' is not a valid callable based on the code provided. Use either a static function 'UserController::getNotification' or construct UserController and pass array($controller, "getNotification") to $app->get().
