Zend Framework 2无法从会话中检索值

Question

我在Zend Framework2中的会话处理方面遇到了问题

为什么在beaconAction中设置$session->带宽后，在fileAction中仍然是'null‘？

public function fileAction() {
    $session = new SessionContainer();
    $bandwidth = $session->bandwidth;
    var_dump($session->bandwidth);
    die;
    $settings = $this->getSettings();
    $this->lightbox($this);
    return new ViewModel(array(
        'file' => $this->getEvent()->getRouteMatch()->getParam('file'),
        'film_path' => $settings['film_path'],
        'poster_file' => $settings['poster_file'],
    ));
}

public function beaconAction() {
    $session = new SessionContainer();
    $bandwidth = $this->getRequest()->getQuery('bw');
    $session->bandwidth = $bandwidth;
    var_dump($session->bandwidth);
    return new ViewModel(array(
        'bandwidth' => $bandwidth
    ));
}

也许可以尝试设置会话容器的名称空间，并检查查询数据http://framework.zend.com/manual/2.2/en/modules/zend.session.container.html#basic-usage

public function fileAction() {
    $session = new SessionContainer("mybeaconsession");  // <--- this
    $bandwidth = $session->bandwidth;
    var_dump($session->bandwidth);
    die;
    $settings = $this->getSettings();
    $this->lightbox($this);
    return new ViewModel(array(
        'file' => $this->getEvent()->getRouteMatch()->getParam('file'),
        'film_path' => $settings['film_path'],
        'poster_file' => $settings['poster_file'],
    ));
}

public function beaconAction() {
    $session = new SessionContainer("mybeaconsession");     // <-- try this
    $bandwidth = $this->params('bw');                       // <-- try this
    $session->bandwidth = $bandwidth;
    var_dump($session->bandwidth);
    return new ViewModel(array(
        'bandwidth' => $bandwidth
    ));
}
