php - PhalconPHP-如何向用户显示500错误

Question

如何使用PhalconPHP 来向用户显示500错误？

我使用此代码显示404错误(显示错误404.volt View )和500错误(显示错误500.volt View )。
404错误页面将按预期显示，但不会显示500错误页面。

$di->set('dispatcher', function() {
 //Create/Get an EventManager
 $eventsManager = new \Phalcon\Events\Manager();
 //Attach a listener
 $eventsManager->attach("dispatch:beforeException", function($event, $dispatcher, $exception) {
 //Handle 404 exceptions
 if ($exception instanceof \Phalcon\Mvc\Dispatcher\Exception) {
 $dispatcher->forward(array(
 'controller' => 'index',
 'action' => 'error404'
 ));
 return false;
 }
 //Handle other exceptions
 $dispatcher->forward(array(
 'controller' => 'index',
 'action' => 'error500'
 ));
 return false;
 });
 $dispatcher = new \Phalcon\Mvc\Dispatcher();
 //Bind the EventsManager to the dispatcher
 $dispatcher->setEventsManager($eventsManager);
 return $dispatcher;
}, true);

您可以通过在转发 Controller 的操作中设置请求的状态来做到这一点。在您的情况下indexController::error500Action()

$this->response->setStatusCode(500, "Internal Server Error");
