php – 将Zend_Auth存储后端$_SESSION更改为Memcached

$oBackend = new Zend_Cache_Backend_Libmemcached(
        array(
            'servers' => $servers,'compression' => false
    ) );

    // configure caching frontend strategy
    $oFrontend = new Zend_Cache_Core(
        array(
            'caching' => true,'automatic_serialization' => true
        ) );

    // build a caching object
    $cache = Zend_Cache::factory( $oFrontend,$oBackend );

    $saveHandler = new ApplicationAuthAdapterMemcached();
    $saveHandler->setCacher($cache);

    Zend_Session::setSaveHandler($saveHandler);

它正在保存值memcache成功没有问题.我测试

$namespace = new Zend_Session_Namespace();
    $namespace->name = "Fatih";

在其他控制器

$ns = new Zend_Session_Namespace();
    var_dump($ns->name);

没关系,但是我不能在memcache中看到Zend_Auth的值.但是如果我的var_dump($_ SESSION)
我可以看到它像

["Zend_Auth"]=> array(1) { ["storage"]=> object(Application_Security_Auth_Storage)#66 (1) { ["_user":protected]=> object(Application_Security_Auth_User)#84 (4) { ["id":protected]=> object(MongoId)#87 (1) { ["$id"]=> string(24) "4fcca6b8c863c79d33000004" } ["username":protected]=> string(5) "admin" ["role":protected]=> string(5) "admin" ["fullname":protected]=> NULL } } }

在这里可以看到我的登录方式;

public function login($username,$password)
{
    if ($username == "" || $password == "")
        return false;

    $adapter = new Application_Security_Auth_Adapter();

    $adapter->setIdentity($username);
    $adapter->setCredential($password);

    $auth = Zend_Auth::getInstance();
    $result = $auth->authenticate($adapter);

    return $result->isValid();
}
