Zend Framework 2,模块重定向 [英] Zend Framework 2, Module Redirect
本文介绍了Zend Framework 2,模块重定向的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我的 module.php 中有一个函数,该函数在其他所有内容开始加载之前调用,它验证用户是否已登录,但如果用户未登录,我需要它重定向到登录页面在,我可以只使用header",但我想学习Zend"的做事方式.
I have a function in my module.php with the following function which is called before everything else starts to load, it verifies that the user is logged on but I need it to redirect to the login page if the user is not logged in, I could just use "header" but I want to learn the "Zend" way of doing things.
public function preDispatch($e)
{
if (!isset($_SESSION)) session_start();
$sm = $e->getApplication()->getServiceManager();
$adapters = $sm->get('dbAdapters');
if (!isset($_SESSION['auth'])) $_SESSION['auth'] = new MyAuth($adapters[1]);
if ($_SESSION['auth']->IsValid())
{
echo 'Valid<br />';
}
else
{
$e->getControllerClass()->redirect()->toRoute('login-success');
echo '!Valid<br />';
//REDIRECT TO LOGIN PAGE HERE!!!!!
}
}
推荐答案
这正是您要问的问题:
//REDIRECT TO LOGIN PAGE HERE!!!!!
/**
* grab Controller instance from event and use the native redirect plugin
*/
$controller = $e->getTarget();
$controller->plugin('redirect')->toUrl('/logout?' . $query);
/**
* optionally stop event propagation and return FALSE
*/
$e->stopPropagation();
return FALSE;
话虽如此,您可能需要重新考虑使用原始会话.示例(假设您已配置自定义 authAdapter):
That being said, you might want to reconsider using the raw session. Example (assumes you've configured a custom authAdapter):
public function checkSession($e)
{
$controller = $e->getTarget(); // grab Controller instance from event
$app = $e->getApplication();
$locator = $app->getServiceManager();
if ($controller instanceof LogoutController) return;
$authService = $locator->get('ds_auth_service');
$authAdapter = $locator->get('ds_auth_adapter');
/*
* try to authenticate
*/
if (!$authService->hasIdentity()){
$result = $authService->authenticate($authAdapter);
if ($authService->hasIdentity()) {
$this->getEventManager()->trigger('authenticate', $this, array('result' => $result));
}
}
/*
* If we are not in an exempt controller and no valid identity, redirect
*/
$isExempt = $controller instanceof \Application\Controller\LogoutController;
if (!$isExempt && !$authService->hasIdentity()) {
$query = http_build_query($result->getMessages());
$controller->plugin('redirect')->toUrl('/logout?' . $query);
$e->stopPropagation();
return FALSE;
}
// User is logged in
return TRUE;
}
