[英]How to catch my own Model Exceptions in a Zend Framework Action
我有一个抛出XMLDocument_Exception的模型。 在我的控制器操作中,我想包含一个try catch块,该块可能会引发此异常,但是由于某种原因它没有被捕获。
public function listissuesAction() {
$publicationPid = $this->_request->get('publicationPid');
$this->getFrontController()->throwExceptions(true);
try {
$fedoraPublication = new FedoraMETSPublication($publicationPid);
} catch (XMLDocument_Exception $e) {
return $this->_forward('content/unavailable');
}
}
并且该模型将引发异常,如下所示:
if ($mets) {
$this->loadXML($mets);
} else {
throw new XMLDocument_Exception('Failed to load METS Document from SOAP Server');
}
FedoraMETSPublication扩展了FedoraMETS,后者扩展了XMLDocument。 上面的代码在FedoraMETS的构造函数中。
我看到以下错误:
Fatal error: Uncaught exception 'XMLDocument_Exception' with message 'Failed to load METS Document from SOAP Server' in 2 /Users/dof/Sites/ccymod/trunk/application/models/Fedora/METS.php:21

为什么我的动作控制器中没有捕获此异常?
检查堆栈跟踪,#2:
#2 /Users/dof/Sites/ccymod/trunk/application/views/scripts/browse/listissues.phtml(19): FedoraMETSPublication->getIssues()
显然,异常是抛出给视图而不是控制器。 在视图中使用try...catch
(或更改您的方法)。
