如何在ZF3中自定义标题标签和元标签描述？

Question

我使用的是Zend描述，我试图像ZF2文档处理推荐的那样定制标题标记，但是我得到了以下错误：

未登录的Zend\ServiceManager\Exception\ServiceNotFoundException:无法将服务"viewHelperManager“解析为工厂；您确定在配置期间提供了吗？在/var/www/html/basketmetrics/vendor/zendframework/zend-servicemanager/src/ServiceManager.php:681堆栈跟踪中：#0 /var/www/html/basketmetrics/vendor/zendframework/zend-servicemanager/src/ServiceManager.php(757)：Zend\ServiceManager\ServiceManager->getFactory('viewHelperManag...') 1 /var/www/html/basketmetrics/vendor/zendframework/zend-servicemanager/src/ServiceManager.php(200)：Zend\ServiceManager\ServiceManager->doCreate('viewHelperManag...') #2 /var/www/html/basketmetrics/module/Stats/src/Module.php(43)：Zend\ServiceManager\ServiceManager->get('viewHelperManag...') #3 /var/www/html/basketmetrics/vendor/zendframework/zend-eventmanager/src/EventManager.php(322)：Stats\Module->setLayoutTitle(Object(Zend\Mvc\MvcEvent)) #4 /var/www/html/basketmetrics/vendor/zendframework/zend-eventmanager/src/EventManager.php(171)：Zend\EventManager\E在第681行的/var/www/html/basketmetrics/vendor/zendframework/zend-servicemanager/src/ServiceManager.php中

这是我在Module.php上的代码

namespace Stats;

class Module
{
    const VERSION = '3.0.2';

    public function getConfig()
    {
        return include __DIR__ . '/../config/module.config.php';
    }

    /**
     * @param  \Zend\Mvc\MvcEvent $e The MvcEvent instance
     * @return void
     */
    public function onBootstrap($e)
    {
        // Register a render event
        $app = $e->getParam('application');
        $app->getEventManager()->attach('render', array($this, 'setLayoutTitle'));
    }

    /**
     * @param  \Zend\Mvc\MvcEvent $e The MvcEvent instance
     * @return void
     */
    public function setLayoutTitle($e)
    {
        $matches    = $e->getRouteMatch();
        $action     = $matches->getParam('action');
        $controller = $matches->getParam('controller');
        $module     = __NAMESPACE__;
        $siteName   = 'BasketMetrics';

        // Getting the view helper manager from the application service manager
        $viewHelperManager = $e->getApplication()->getServiceManager()->get('viewHelperManager');

        // Getting the headTitle helper from the view helper manager
        $headTitleHelper   = $viewHelperManager->get('headTitle');

        // Setting a separator string for segments
        $headTitleHelper->setSeparator(' - ');

        // Setting the action, controller, module and site name as title segments
        $headTitleHelper->append($action);
        $headTitleHelper->append($controller);
        $headTitleHelper->append($module);
        $headTitleHelper->append($siteName);
    }    

}

我不知道我是做错了什么，还是不能像在ZF2中那样做。

和元标签“描述”，我如何定制它？
