如何使用 Zend 2 保存处理程序 DbTableGateway？

Question

Zend\Session Save Handler tutorial gives an example for DbTableGateway in which they create a TableGateway with an undefined $adapter variable. I want to use the handler to tie the Session Manager（从教程的上一页）到我的数据库中的会话存储table。我该怎么做？

我猜代码应该是这样的？

class Module implements AutoloaderProviderInterface, ConfigProviderInterface
{
    public function onBootstrap(MvcEvent $e) {
        $eventManager        = $e->getApplication()->getEventManager();

        // create the session manager
        $moduleRouteListener = new ModuleRouteListener();
        $moduleRouteListener->attach($eventManager);
        $this->bootstrapSession($e);
    }

    public function bootstrapSession($e)
    {
        $session = $e->getApplication()
            ->getServiceManager()
            ->get('Zend\Session\SessionManager');
        $tableGateway = new TableGateway('session', $adapter); // somehow define this somewhere?
        $saveHandler  = new DbTableGateway($tableGateway, new DbTableGatewayOptions());
        $session->setSaveHandler($saveHandler);
        $session->start();

        $container = new Container('initialized');
        if (!isset($container->init)) {
            $serviceManager = $e->getApplication()->getServiceManager();
            $request        = $serviceManager->get('Request');

            $session->regenerateId(true);
            $container->init          = 1;
            $container->remoteAddr    = $request->getServer()->get('REMOTE_ADDR');
            $container->httpUserAgent = $request->getServer()->get('HTTP_USER_AGENT');

            $config = $serviceManager->get('Config');
            if (!isset($config['session'])) {
                return;
            }

            $sessionConfig = $config['session'];
            if (isset($sessionConfig['validators'])) {
                $chain   = $session->getValidatorChain();

                foreach ($sessionConfig['validators'] as $validator) {
                    switch ($validator) {
                        case 'Zend\Session\Validator\HttpUserAgent':
                            $validator = new $validator($container->httpUserAgent);
                            break;
                        case 'Zend\Session\Validator\RemoteAddr':
                            $validator  = new $validator($container->remoteAddr);
                            break;
                        default:
                            $validator = new $validator();
                    }

                    $chain->attach('session.validate', array($validator, 'isValid'));
                }
            }
        }
    }

    public function getServiceConfig()
    {
        return array(
            'factories' => array(
                'Zend\Session\SessionManager' => function ($sm) {
                    $config = $sm->get('config');
                    if (isset($config['session'])) {
                        $session = $config['session'];

                        $sessionConfig = null;
                        if (isset($session['config'])) {
                            $class = isset($session['config']['class'])  ? $session['config']['class'] : 'Zend\Session\Config\SessionConfig';
                            $options = isset($session['config']['options']) ? $session['config']['options'] : array();
                            $sessionConfig = new $class();
                            $sessionConfig->setOptions($options);
                        }

                        $sessionStorage = null;
                        if (isset($session['storage'])) {
                            $class = $session['storage'];
                            $sessionStorage = new $class();

                        if (isset($session['save_handler'])) {
                            // class should be fetched from service manager since it will require constructor arguments
                            $sessionSaveHandler = $sm->get($session['save_handler']);
                        }

                        $sessionManager = new SessionManager($sessionConfig, $sessionStorage, $sessionSaveHandler);
                    } else {
                        $sessionManager = new SessionManager();
                    }
                    Container::setDefaultManager($sessionManager);
                    return $sessionManager;
                },
            ),
        );
    }

我有这段代码可以将会话保存到数据库 table。

'service_manager' => array(
    'factories' => array(
        'Zend\Session\SessionManager' => function (\Zend\ServiceManager\ServiceManager $sm) {
            $sessionConfig = new \Zend\Session\Config\SessionConfig();
            $sessionConfig->setOptions(
                array(
                    'use_cookies' => true,
                    'name' => 'ed2',
                    'gc_maxlifetime' => 1728000
                )
            );

            /* @var $adapter \Zend\Db\Adapter\Adapter */
            $adapter = $sm->get('Zend\Db\Adapter\Adapter');
            $tableGateway = new \Zend\Db\TableGateway\TableGateway('session', $adapter);
            $saveHandler  = new \Common\Session\SaveHandler\DbTableGateway(
                $tableGateway,
                new \Zend\Session\SaveHandler\DbTableGatewayOptions()
            );

            $sessionManager = new \Zend\Session\SessionManager($sessionConfig);
            $sessionManager->setSaveHandler($saveHandler);
            $sessionManager->start();
            return $sessionManager;
        },
    )
)

配置 db

'db' => array(
    'driver'    => 'Pdo_Mysql',
    'database'  => 'release',
    'username'  => 'username',
    'password'  => 'password',
    'hostname'  => '127.0.0.1',
    'driver_options' => array(
        PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES \'UTF8\''
    )
),
'service_manager' => array(
    'factories' => array(
        'Zend\Db\Adapter\Adapter' => function (\Zend\ServiceManager\ServiceManager $serviceManager) {
            $adapterFactory = new Zend\Db\Adapter\AdapterServiceFactory();
            $adapter = $adapterFactory->createService($serviceManager);

            Zend\Db\TableGateway\Feature\GlobalAdapterFeature::setStaticAdapter($adapter);

            return $adapter;
        }
    )
)

Answer 2

~~答案竟然和newage的答案一样：~~

自从 newage 编辑了他的答案以包含数据库适配器后，我就接受了它作为正确答案。剩下的只是我的实现：

你可以把bootstrapSession方法中所有的TableGateway和savehandler逻辑去掉，放在getServiceConfig方法中。

将 Adapter 的定义添加到 getServiceConfig 中的 'factories' 数组，然后修改 'Zend\Session\SessionManager' 函数以包含 Adapter、TableGateway 和保存处理程序。这就是新的 getServiceConfig 的样子：

public function getServiceConfig()
{
    return array(
        'factories' => array(

            // New code here
            'Zend\Db\Adapter\Adapter' => 'Zend\Db\Adapter\AdapterServiceFactory',
            // New code here

            'Zend\Session\SessionManager' => function ($sm) {
                $config = $sm->get('config');
                if (isset($config['session'])) {
                    $session = $config['session'];

                    $sessionConfig = null;
                    if (isset($session['config'])) {
                        $class = isset($session['config']['class'])  ? $session['config']['class'] : 'Zend\Session\Config\SessionConfig';
                        $options = isset($session['config']['options']) ? $session['config']['options'] : array();
                        $sessionConfig = new $class();
                        $sessionConfig->setOptions($options);
                    }

                    $sessionStorage = null;
                    if (isset($session['storage'])) {
                        $class = $session['storage'];
                        $sessionStorage = new $class();
                    }

                    $sessionSaveHandler = null;
                    if (isset($session['save_handler'])) {
                        // class should be fetched from service manager since it will require constructor arguments
                        $sessionSaveHandler = $sm->get($session['save_handler']);
                    }
                    $sessionManager = new SessionManager();
                }

                // New code here
                /* @var $adapter \Zend\Db\Adapter\Adapter */
                $adapter = $sm->get('Zend\Db\Adapter\Adapter');
                $tableGateway = new TableGateway('mytablename', $adapter);
                $saveHandler  = new DbTableGateway($tableGateway, new DbTableGatewayOptions());
                $sessionManager->setSaveHandler($saveHandler);
                // New code here

                Container::setDefaultManager($sessionManager);
                return $sessionManager;
            },
        ),
    );
}

然后将数据库连接信息添加到模块的配置文件中：

return array(
    // ...
    'db' => array(
        'driver'         => 'Pdo',
        'dsn'            => 'mysql:dbname=mydbname;host=mydbhost;port=xxxx',
        'driver_options' => array(
            PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES \'UTF8\''
        ),
        'username'       => 'dbusername',
        'password'       => 'dbpassword',
    ),
);
