ZF2 SessionManager 使用

问题描述

我是 ZF2 的新手，不太习惯如何做事.我想使用会话来跟踪用户(记住我).我在课堂上的一个部分有这段代码:

I am new to ZF2 and not quite used to how to do stuff. I want to use session to keep track of an user (remember me). I had this code in one part of my class:

$sessionManager = new \Zend\Session\SessionManager();
$sessionManager->rememberMe($time);

// i want to keep track of my user id too
$populateStorage = array('user_id' => $user->getId());
$storage = new ArrayStorage($populateStorage);
$sessionManager->setStorage($storage);

好的，到目前为止一切顺利.当我尝试:

Ok, so far so good. When i try:

var_dump($sessionManager->getStorage());

我得到了预期的数据.

在我程序的另一部分，我想再次检索我的数据(有点像容器):

In another part of my program, i want to retreive my data again (a bit like containers):

$sessionManager = new \Zend\Session\SessionManager();
var_dump($sessionManager->getStorage());

这只会返回一个空对象.我想这是由于新"，我认为我必须以不同的方式实现 SessionManager，但是如何实现?我不知道.这是我想出的:

This only returns an empty object.I guess this is due to the "new" and i think i have to implement SessionManager in a different way, but how? I do not know. This is what i came up with:

在我的模块中，我现在有:

In my Module i now have:

public function onBootstrap(\Zend\Mvc\MvcEvent $e)
{
    $config = $e->getApplication()
            ->getServiceManager()
            ->get('Configuration');

    $sessionConfig = new SessionConfig();
    $sessionConfig->setOptions($config['session']);
    $sessionManager = new SessionManager($sessionConfig);
    $sessionManager->start();

在我的 module.config 中:

In my module.config:

'session' => array(
    'remember_me_seconds' => 2419200,
    'use_cookies' => true,
    'cookie_httponly' => true,
),

但是如何进行呢?如何获取 sessionManager 的实例?

But how to procede? How do i get the instance for my sessionManager?

推荐答案

没有很好的文档记录 SessionManagerFactory (zf2 api doc) 和 SessionConfigFactory (zf2api 文档).使用这些实例化 SessionManager 非常简单，只需将这些工厂放入您的 ServiceManager 配置中:

There is not well documented SessionManagerFactory (zf2 api doc) and SessionConfigFactory (zf2 api doc). With those is instantiate SessionManager very easy, just put these factories to your ServiceManager configuration:

'service_manager' => [
    'factories' => [
        'Zend\Session\SessionManager' => 'Zend\Session\Service\SessionManagerFactory',
        'Zend\Session\Config\ConfigInterface' => 'Zend\Session\Service\SessionConfigFactory',
    ],
],

并在模块配置中将您的会话选项放在 session_config 键下:

and to module configuration put your session options, under the session_config key:

'session_config' => [
    'remember_me_seconds' => 2419200,
    'use_cookies' => true,
    'cookie_httponly' => true,
],

就是这样，现在您可以从服务定位器的任何地方获取 SessionManager，例如在控制器中:

and that's it, now you can grab SessionManager from service locator anywhere, for example in controller:

/** @var Zend\Session\SessionManager $sm */
$sessionManager = $this->serviceLocator->get('Zend\Session\SessionManager');

自 Zend Framework 2.2 版起可用(相关拉取请求).

This is available as of 2.2 version of Zend Framework (related pull request).
