我正在忙于编写数据库会话模块，因此我可以在多个应用程序之间快速安装它。该模块将作为要启动的第一个模块从自动装载器加载。我想要完成的是将默认会话容器/会话处理程序更改为所有模块的默认会话处理程序，它也应该是数据库托管会话。我已经与zf2会话处理程序争论了很长一段时间，并且日志中的错误有意义。所以我到目前为止所拥有的。 Module.php的基本模块包含...
命名空间DBSession;
use Zend\Mvc\ModuleRouteListener;
class Module {
public function onBootstrap($e) {
$e->getApplication()->getServiceManager()->get('translator');
$eventManager = $e->getApplication()->getEventManager();
$moduleRouteListener = new ModuleRouteListener();
$moduleRouteListener->attach($eventManager);
$config = $e->getApplication()->getServiceManager()->get('Config');
$controller = $e->getTarget();
$controller->config = $config;
new \DBSession\Storage\DBStorage();
}
public function getConfig() {
return include __DIR__ . '/config/module.config.php';
}
public function getAutoloaderConfig() {
return array(
'Zend\Loader\ClassMapAutoloader' => array(
__DIR__ . '/autoload_classmap.php',
),
'Zend\Loader\StandardAutoloader' => array(
'namespaces' => array(
__NAMESPACE__ => __DIR__ . '/src/' . __NAMESPACE__,
),
),
);
}
}
启动数据库会话处理程序的实际类。
namespace DBSession\Storage;
use Zend\Session\SaveHandler\DbTableGateway;
use Zend\Session\SaveHandler\DbTableGatewayOptions;
use Zend\Db\Adapter\Adapter;
use Zend\Session\SessionManager;
use Zend\Session\Container;
class DBStorage {
public function __construct() {
$dbAdapter = new Adapter(array(
'driver' => 'Mysqli',
'host' => 'localhost',
'dbname' => 'zf2_session',
'username' => 'zf2',
'password' => 'testme',
'options' => array(
'buffer_results' => true,
),
));
$tableGateway = new \Zend\Db\TableGateway\TableGateway('session', $dbAdapter);
$gwOpts = new DbTableGatewayOptions();
$gwOpts->setDataColumn('data');
$gwOpts->setIdColumn('id');
$gwOpts->setLifetimeColumn('lifetime');
$gwOpts->setModifiedColumn('modified');
$gwOpts->setNameColumn('name');
$saveHandler = new DbTableGateway($tableGateway, $gwOpts);
$sessionManager = new SessionManager();
$sessionManager->setSaveHandler($saveHandler);
return Container::setDefaultManager($sessionManager);
}
}
尝试创建会话时，我在日志中看到以下内容，我知道如何修复。这开始让我讨厌魔术......

更新：
zend framework＆gt; = 2.2，此问题已不复存在。
旧回答：
我在将会话存储到数据库时遇到了同样的问题，我在基本模块类\module\Application\Module.php中编写了initDbSession函数
class Module
{
public function onBootstrap(MvcEvent $e)
{
$e->getApplication()->getServiceManager()->get('translator');
$eventManager = $e->getApplication()->getEventManager();
$moduleRouteListener = new ModuleRouteListener();
$moduleRouteListener->attach($eventManager);
// session start from here
$this->initDbSession( $e );
}
/**
* Store session into database
*
* @param type $e
*/
private function initDbSession( MvcEvent $e )
{
// grab the config array
$serviceManager = $e->getApplication()->getServiceManager();
$config = $serviceManager->get('config');
$dbAdapter = $serviceManager->get('Zend\Db\Adapter\Adapter');
/* some how this not works for me
$sessionOptions = new \Zend\Session\SaveHandler\DbTableGatewayOptions( null );
$sessionTableGateway = new \Zend\Db\TableGateway\TableGateway('session', $dbAdapter);
$saveHandler = new \Zend\Session\SaveHandler\DbTableGateway($sessionTableGateway, $sessionOptions);
*/
/* I written my own save handler , I am using mysql as database */
$saveHandler = new \My\Session\SaveHandler\Mysql( $config['db'] );
$sessionConfig = new \Zend\Session\Config\SessionConfig();
$sessionConfig->setOptions($config['session']);
// pass the saveHandler to the sessionManager and start the session
$sessionManager = new \Zend\Session\SessionManager( $sessionConfig , NULL, $saveHandler );
$sessionManager->start();
\Zend\Session\Container::setDefaultManager($sessionManager);
}
// other function goes here ...
这是我的配置文件，位于\config\autoload\global.php
return array(
'db' => array(
'driver' => 'Pdo',
'dsn' => 'mysql:dbname=zf2;host=localhost',
'driver_options' => array(
PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES \'UTF8\'',
'buffer_results' => true
),
'username' => 'root',
'password' => '',
'host' => 'localhost',
'dbname' => 'zf2',
),
'session' => array(
'remember_me_seconds' => 2419200,
'use_cookies' => true,
'cookie_httponly' => true,
'cookie_lifetime' => 2419200,
'gc_maxlifetime' => 2419200,
),
'service_manager' => array(
'factories' => array(
'Zend\Db\Adapter\Adapter' => 'Zend\Db\Adapter\AdapterServiceFactory'
)
)
);
Mysql表结构是
CREATE TABLE `session` (
`id` CHAR(32) NOT NULL DEFAULT '',
`name` VARCHAR(255) NOT NULL,
`modified` INT(11) NULL DEFAULT NULL,
`lifetime` INT(11) NULL DEFAULT NULL,
`data` TEXT NULL,
PRIMARY KEY (`id`)
)COLLATE='utf8_general_ci' ENGINE=InnoDB;
下面给出了自定义Mysql保存处理程序类。我写了这个课，因为新的Zend\Session\SaveHandler\DbTableGateway
不在我的服务器上工作。我在\library\My\Session\SaveHandler\Mysql.php

在最近进入ZF2的所有修复程序之后，我的原始解决方案现在无需修改即可工作，但是我为任何想要使用它的人添加了一个新的编写器模块，它减少了手动执行所有操作的需要。 / p>

这是另一个类似的解决方案： How to use cookie in Zend Framework 2?
确保更改此行：
Session::setDefaultManager($sessionManager);
有了这个：
Container::setDefaultManager($sessionManager);
使用：
use Zend\Session\Container;
