$GLOBALS['TSFE']->fe_user->setKey("ses","key",$value)
$GLOBALS["TSFE"]->fe_user->getKey("ses","key")
更新 自 TYPO3 v10 起，使用 $GLOBALS["TSFE"] 已经过时，所以如果您需要解决方案，请参考 https://dev59.com/QnTYa4cB1Zd3GeqPpwac#76817091
setKey 之后不要忘记 $GLOBALS['TSFE']->fe_user->storeSessionData();。 - Hafenkranich<?php
class Tx_EXTNAME_Service_SessionHandler implements t3lib_Singleton {

public function restoreFromSession($key) {
$sessionData = $GLOBALS['TSFE']->fe_user->getKey('ses', $this->prefixKey . $key);
return unserialize($sessionData);

将此类注入到您的控制器中
/**
*
* @var Tx_EXTNAME_Service_SessionHandler
*/
protected $sessionHandler;
/**
*
* @param Tx_EXTNAME_Service_SessionHandler $sessionHandler
*/
public function injectSessionHandler(Tx_EXTNAME_Service_SessionHandler $sessionHandler) {
$this->sessionHandler = $sessionHandler;
}
// Write your object into session
$this->sessionHandler->writeToSession('KEY_FOR_THIS_PROCESS');
// Get your object from session
$this->sessionHandler->restoreFromSession('KEY_FOR_THIS_PROCESS');
// And after all maybe you will clean the session (delete)
$this->sessionHandler->cleanUpSession('KEY_FOR_THIS_PROCESS');
将Tx_EXTNAME和tx_extname重命名为您的扩展名，并注意将会话处理程序类放入正确的目录中（Classes-> Service-> SessionHandler.php）。
您可以存储任何数据，而不仅仅是对象。
希望对您有所帮助。
从Typo3 v7开始，您还可以复制原生会话处理程序(\TYPO3\CMS\Form\Utility\SessionUtility)用于表单，并根据需要进行更改。该类区分普通用户和已登录用户，并支持通过sessionPrefix分隔的多个会话数据。
我也做了同样的事情，将该类推广到更常见的目的。我只删除了一个方法，更改了变量名称并添加了hasSessionKey()方法。以下是我的完整示例：
use TYPO3\CMS\Frontend\Controller\TypoScriptFrontendController;
/**
* Class SessionUtility
*
* this is just a adapted version from \TYPO3\CMS\Form\Utility\SessionUtility,
* but more generalized without special behavior for form
*
*
*/
class SessionUtility {
/**
* Session data
*
* @var array
*/
protected $sessionData = array();
/**
* Prefix for the session
*
* @var string
*/
protected $sessionPrefix = '';
/**
* @var TypoScriptFrontendController
*/
protected $frontendController;
/**
* Constructor
*/
public function __construct()
{
$this->frontendController = $GLOBALS['TSFE'];
}
/**
* Init Session
*
* @param string $sessionPrefix
* @return void
*/
public function initSession($sessionPrefix = '')
{
$this->setSessionPrefix($sessionPrefix);
if ($this->frontendController->loginUser) {
$this->sessionData = $this->frontendController->fe_user->getKey('user', $this->sessionPrefix);
} else {
$this->sessionData = $this->frontendController->fe_user->getKey('ses', $this->sessionPrefix);
}
}
/**
* Stores current session
*
* @return void
*/
public function storeSession()
{
if ($this->frontendController->loginUser) {
$this->frontendController->fe_user->setKey('user', $this->sessionPrefix, $this->getSessionData());
} else {
$this->frontendController->fe_user->setKey('ses', $this->sessionPrefix, $this->getSessionData());
}
$this->frontendController->storeSessionData();
}
/**
* Destroy the session data for the form
*
* @return void
*/
public function destroySession()
{
if ($this->frontendController->loginUser) {
$this->frontendController->fe_user->setKey('user', $this->sessionPrefix, null);
} else {
$this->frontendController->fe_user->setKey('ses', $this->sessionPrefix, null);
}
$this->frontendController->storeSessionData();
}
/**
* Set the session Data by $key
*
* @param string $key
* @param string $value
* @return void
*/
public function setSessionData($key, $value)
{
$this->sessionData[$key] = $value;
$this->storeSession();
}
/**
* Retrieve a member of the $sessionData variable
*
* If no $key is passed, returns the entire $sessionData array
*
* @param string $key Parameter to search for
* @param mixed $default Default value to use if key not found
* @return mixed Returns NULL if key does not exist
*/
public function getSessionData($key = null, $default = null)
{
if ($key === null) {
return $this->sessionData;
}
return isset($this->sessionData[$key]) ? $this->sessionData[$key] : $default;
}
/**
* Set the s prefix
*
* @param string $sessionPrefix
*
*/
public function setSessionPrefix($sessionPrefix)
{
$this->sessionPrefix = $sessionPrefix;
}
/**
* @param string $key
*
* @return bool
*/
public function hasSessionKey($key) {
return isset($this->sessionData[$key]);
}
}
不要忘记先调用 initSession 方法，在您想使用该类的任何方法时都需要这样做。
由于用户搜索类似于 typo3 extbase session data 的内容时会找到此线程，因此答案 ($GLOBALS['TSFE']) 已过时，在TYPO3 v11.5或v12.4中采用了现代方法来回答此问题。
<?php
namespace MyVendor\MyExtension\Controller;
use Psr\Http\Message\ResponseInterface;
use TYPO3\CMS\Extbase\Mvc\Controller\ActionController;
use TYPO3\CMS\Frontend\Authentication\FrontendUserAuthentication;
class CustomController extends ActionController
{
/** @var FrontendUserAuthentication */
protected $frontendUser;
/**
* Share $frontendUser to all actions.
* initializeAction() instead of _construct() because we need the request object.
*/
public function initializeAction(): void
{
parent::initializeAction();
$this->frontendUser = $this->request->getAttribute('frontend.user');
}
/**
* The first action which save some data in the frontend user session.
*
* @return ResponseInterface
*/
public function firstAction(): ResponseInterface
{
$this->frontendUser->setAndSaveSessionData('myKey', 'myMixedData');
// Do stuff...
return $this->htmlResponse();
}
/**
* The second action which fetches the data from the frontend user session.
*
* @return ResponseInterface
*/
public function secondAction(): ResponseInterface
{
$this->frontendUser->getSessionData('myKey');
// Do stuff...
return $this->htmlResponse();
}
}
