问题
I'm trying to adapt my ZF2 User module to ZF3 MVC. It has an authentication service manager that is called in the onBootsrap function inside the Module class for every request (i.e. page loading) to check if the user is authenticated.
As serviceLocator and ServiceAware are not available anymore I'm trying to create an AuthenticationServiceFactory but I do not succeed yet. Would you have any ideas on what I'm doing wrong and how I could do it with ZF3 ?
Here is a simplified version of my module/User/config.module.config.php file
namespace User;
use ...
return [
'router' => [...],
'controllers' => [...],
'service_manager' => [
'factories' => [
Service\AuthenticationServiceFactory::class => InvokableFactory::class,
],
],
];
Here is my module/User/src/Service/AuthenticationServiceFactory.php file
namespace User\Service;
use Interop\Container\ContainerInterface;
use Zend\Authentication\AuthenticationService;
use Zend\ServiceManager\Factory\FactoryInterface;
use Zend\Db\Adapter\Adapter as DbAdapter;
use Zend\Authentication\Adapter\DbTable\CredentialTreatmentAdapter as AuthAdapter;
use Zend\Authentication\Storage\Session as Storage;
class AuthenticationServiceFactory implements FactoryInterface
{
public function __invoke(ContainerInterface $container, $requestedName, array $options = null)
{
$controllerPluginManager = $container;
$serviceManager = $controllerPluginManager->get('ServiceManager');
$config = $serviceManager->get('configuration');
$dbAdapter = new DbAdapter($config['db']); // Mysqli driver working in other modules
$authAdapter = new AuthAdapter($dbAdapter);
$authAdapter->setTableName('user')->setIdentityColumn('username')->setCredentialColumn('password');
$storage = new Storage();
return new AuthenticationService($storage, $authAdapter);
}
}
Here is my module/User/src/Module.php file
namespace User\Service;
use Zend\Mvc\MvcEvent;
use Zend\Authentication\Adapter\DbTable\CredentialTreatmentAdapter;
class Module
{
public function getConfig()
{
return include __DIR__ . '/../config/module.config.php';
}
public function onBootstrap(MvcEvent $e)
{
$services = $e->getApplication()->getServiceManager();
$auth = $services->get(AuthenticationServiceFactory::class);
// Returns Fatal error: Call to undefined method Zend\Authentication\AuthenticationServiceFactory::setIdentity()
// $auth is an AuthenticationServiceFactory object and not the AuthenticationService returned by its __invoke() function
$this->authAdapter->setIdentity('dummy_user_name');
$this->authAdapter->setCredential('dummy_password');
print_r($this->authAdapter->authenticate());
}
}
Any ideas ?

As usual, when I find the answer by myself, I post it here en case it may help someone.
module/User/config.module.php
namespace User;
use Zend\Router\Http\Literal;
use Zend\Router\Http\Segment;
use Zend\ServiceManager\Factory\InvokableFactory;
return [
'router' => [...],
'controllers' => [...],
'service_manager' => [
'factories' => [
'auth-service' => Service\AuthenticationServiceFactory::class,
],
],
];
module/User/src/Service/AuthenticationServiceFactory.php
namespace User\Service;
use Interop\Container\ContainerInterface;
use Zend\Authentication\AuthenticationService;
use Zend\ServiceManager\Factory\FactoryInterface;
use Zend\Db\Adapter\Adapter as DbAdapter;
use Zend\Authentication\Adapter\DbTable\CredentialTreatmentAdapter as AuthAdapter;
use Zend\Authentication\Storage\Session as Storage;
class AuthenticationServiceFactory implements FactoryInterface
{
public function __invoke(ContainerInterface $container, $requestedName, array $options = null)
{
// Get data from config files.
$controllerPluginManager = $container;
$serviceManager = $controllerPluginManager->get('ServiceManager');
$config = $serviceManager->get('configuration');
// or we can simplify these 3 lines using the following
//$config = $container->get('configuration');
// Configure DbAdapter with set-up information from config files.
$dbAdapter = new DbAdapter($config['db']); // Mysqli driver working in other modules
// Configure AuthAdapter with DbAdapter.
// See https://docs.zendframework.com/zend-authentication/adapter/dbtable/credential-treatment/
$authAdapter = new AuthAdapter($dbAdapter);
$authAdapter->setTableName('user')->setIdentityColumn('username')->setCredentialColumn('password');
// Configure session storage.
$storage = new Storage();
// Return AuthenticationService.
return new AuthenticationService($storage, $authAdapter);
}
}
module/User/src/Module.php
namespace User\Service;
use Zend\Mvc\MvcEvent;
use Zend\Authentication\Adapter\DbTable\CredentialTreatmentAdapter;
class Module
{
public function getConfig()
{
return include __DIR__ . '/../config/module.config.php';
}
public function onBootstrap(MvcEvent $e)
{
// Get the service manager.
$services = $e->getApplication()->getServiceManager();
// Set event to retrieve user's identity for every request.
$eventManager = $e->getApplication()->getEventManager();
$eventManager->attach(MvcEvent::EVENT_ROUTE, array($this, 'protectPage'), -100);
}
public function protectPage(MvcEvent $event)
{
$match = $event->getRouteMatch();
if (! $match) {
// We cannot do anything without a resolved route.
return;
}
// Get AuthenticationService and do the verification.
$services = $event->getApplication()->getServiceManager();
$authService = $services->get('auth-service');
// If user does not have an identity yet.
if (! $authService->hasIdentity()) {
// Do what you want like routing to login page...
}
}
}
My problem was that setting user's identity and credential was not supposed to be done here but rather in a login() function somewhere else. In the Module Class we just need to check the identity.

I upvoted your own answer because I think it's a good one, but maybe this will improve it for the DB connexion.
You wrote that you already have a Mysqli driver working with another module. If you have a repository in this other module for the user table, you can use it and simplify your code with a custom adapter. Supposing your User repository implements User\Model\UserRepositoryInterface:
namespace User\Model;
interface UserRepositoryInterface
{
public function getUser($id);
public function updateUser(User $user);
// other methods...
}
Module\src\Factory\CustomAdapterFactory.php
namespace User\Factory;
use Interop\Container\ContainerInterface;
use User\Adapter\CustomAdapter;
use User\Model\UserRepositoryInterface;
use Zend\ServiceManager\Factory\FactoryInterface;
class CustomAdapterFactory implements FactoryInterface
{
public function __invoke(ContainerInterface $container, $requestedName, array $options = null)
{
return new CustomAdapter($container->get(UserRepositoryInterface::class));
}
}
Your AuthenticationServiceFactory become:
namespace User\Factory;
use Interop\Container\ContainerInterface;
use User\Adapter\CustomAdapter;
use Zend\Authentication\AuthenticationService;
use Zend\ServiceManager\Factory\FactoryInterface;
use Zend\Authentication\Storage\Session as SessionStorage;
class AuthenticationServiceFactory implements FactoryInterface
{
public function __invoke(ContainerInterface $container, $requestedName, array $options = null)
{
$authService = new AuthenticationService();
$storage = new SessionStorage();
$authService->setStorage($storage);
$authService->setAdapter($container->get(CustomAdapter::class));
return $authService;
}
}
Register your factories: module/User/config.module.php
namespace User;
use User\Factory\AuthenticationServiceFactory;
use User\Factory\CustomAdapterFactory;
use User\Factory\UserRepositoryFactory;
use Zend\Authentication\AuthenticationService;
return [
'service_manager' => [
'aliases' => [
Model\UserRepositoryInterface::class => Model\UserRepository::class
],
'factories' => [
Model\UserRepository::class => UserRepositoryFactory::class,
Adapter\CustomAdapter::class => CustomAdapterFactory::class,
MailService::class => MailServiceFactory::class,
AuthenticationService::class => AuthenticationServiceFactory::class,
]
],
// etc...
];
