Can't resolve route - basic login

Question

so I'm currently looking into Neos CMS and wanted to create a very basic login logic. [for practice]

I basically followed: http://flowframework.readthedocs.io/en/stable/TheDefinitiveGuide/PartIII/Security.html#authentication

My Code: [neos/ being the root dir]

Routes: [neos/Configuration/Routes.yaml] Note that's what I added in the beginning of the file, not the whole content of the file.

-
  name: 'Authentication'
  uriPattern: 'authenticate'
  defaults:
    '@package': 'VMP.Auth'
    '@controller': 'Authentication'
    '@action': 'authenticate'

AuthenticationController.php [neos/Packages/Plugins/VMP.Auth/Classes/VMP/Auth/Controller/]

<?php
namespace VMP\Auth\Controller;

use TYPO3\Flow\Annotations as Flow;
use TYPO3\Flow\Mvc\ActionRequest;
use TYPO3\Flow\Security\Authentication\Controller\AbstractAuthenticationController;

class AuthenticationController extends AbstractAuthenticationController {

        /**
         * Displays a login form
         *
         * @return void
         */
        public function indexAction() {
        }

        /**
         * Will be triggered upon successful authentication
         *
         * @param ActionRequest $originalRequest The request that was intercepted by the security framework, NULL if there was none
         * @return string
         */
        protected function onAuthenticationSuccess(ActionRequest $originalRequest = NULL) {
                if ($originalRequest !== NULL) {
                        $this->redirectToRequest($originalRequest);
                }
                $this->redirect('someDefaultActionAfterLogin');
        }

        /**
         * Logs all active tokens out and redirects the user to the login form
         *
         * @return void
         */
        public function logoutAction() {
                parent::logoutAction();
                $this->addFlashMessage('Logout successful');
                $this->redirect('index');
        }

        public function fooAction() {
                print "lol";
        }
}

NodeTypes.yaml [neos/Packages/Plugins/VMP.Auth/Configuration/]

  superTypes:
    'TYPO3.Neos:Plugin': TRUE

        providers:
          'AuthAuthenticationProvider':
            provider: 'PersistedUsernamePasswordProvider'

Index.html [neos/Packages/Plugins/VMP.Auth/Resources/Private/Templates/Authentication/]

<form action="authenticate" method="post">
   <input type="text"
      name="__authentication[TYPO3][Flow][Security][Authentication][Token][UsernamePassword][username]" />
   <input type="password"        name="__authentication[TYPO3][Flow][Security][Authentication][Token][UsernamePassword][password]" />
   <input type="submit" value="Login" />
</form>

**Root.ts2 [neos/Packages/Plugins/VMP.Auth/Resources/TypoScript/]

prototype(VMP.Auth:Plugin) < prototype(TYPO3.Neos:Plugin)
prototype(VMP.Auth:Plugin) {
      package = 'VMP.Auth'
      controller = 'Authentication'
      action = 'index'
}

Problem: if I call: www.neos.dev/authenticate I get:

Validation failed while trying to call VMP\Auth\Controller\AuthenticationController->authenticateAction().

So I think, the route itself does work. I now added the login form of my VMP.Auth Plugin to some page and logged in (with an existing user). The login form uses /authenticate as its action, but now I get the following error:

Page Not Found

Sorry, the page you requested was not found.

#1301610453: Could not resolve a route and its corresponding URI for the given parameters. This may be due to referring to a not existing package / controller / action while building a link or URI. Refer to log and check the backtrace for more details.

I don't really know what's the issue here. I guess my routing is wrong but I can't see it.

Answer 1

your onAuthenticationSuccess method has:

$this->redirect('someDefaultActionAfterLogin');

which is probably triggered (correctly) now. That tries to redirect to an action someDefaultActionAfterLoginAction in your AuthenticationController but this action does not exist. For starters try $this->redirectToUri('/') to just have a redirect to the homepage.
