我尝试按照此处的说明进行操作:http://kohanaframework.org/3.0/guide/kohana/tutorials/error-pages但由于某种原因,我无法捕捉到 HTTP_Exception_404 我仍然得到一个丑陋的错误页面,而不是我的自定义页面。
此外,当我输入 URL error/404/Message 时,我会收到一条丑陋的 Kohana HTTP 404 错误消息。
这是文件结构:
- 模块
- 我的
- init.php
- 类
- Controller
- error_handler.php
- http_response_exception.php
- kohana.php
- Controller
- 观看次数
- error.php
- 我的
代码:
init.php:
<?php defined('SYSPATH') or die('No direct access');
Route::set('error', 'error/<action>(/<message>)', array('action' => '[0-9]++', 'message' => '.+'))
->defaults(array(
'controller' => 'error_handler'
));
http_response_exception.php:
<?php defined('SYSPATH') or die('No direct access');
class HTTP_Response_Exception extends Kohana_Exception {
public static function exception_handler(Exception $e)
{
if (Kohana::DEVELOPMENT === Kohana::$environment)
{
Kohana_Core::exception_handler($e);
}
else
{
Kohana::$log->add(Kohana::ERROR, Kohana::exception_text($e));
$attributes = array
(
'action' => 500,
'message' => rawurlencode($e->getMessage()),
);
if ($e instanceof HTTP_Response_Exception)
{
$attributes['action'] = $e->getCode();
}
// Error sub-request.
echo Request::factory(Route::url('error', $attributes))
->execute()
->send_headers()
->response;
}
}
}
kohana.php:
<?php defined('SYSPATH') or die('No direct script access.');
class Kohana extends Kohana_Core
{
/**
* Redirect to custom exception_handler
*/
public static function exception_handler(Exception $e)
{
Error::exception_handler($e);
}
} // End of Kohana
error_handler.php:
<?php defined('SYSPATH') or die('No direct access');
class Controller_Error_handler extends Controller {
public function before()
{
parent::before();
$this->template = View::factory('template/useradmin');
$this->template->content = View::factory('error');
$this->template->page = URL::site(rawurldecode(Request::$instance->uri));
// Internal request only!
if (Request::$instance !== Request::$current)
{
if ($message = rawurldecode($this->request->param('message')))
{
$this->template->message = $message;
}
}
else
{
$this->request->action = 404;
}
}
public function action_404()
{
$this->template->title = '404 Not Found';
// Here we check to see if a 404 came from our website. This allows the
// webmaster to find broken links and update them in a shorter amount of time.
if (isset ($_SERVER['HTTP_REFERER']) AND strstr($_SERVER['HTTP_REFERER'], $_SERVER['SERVER_NAME']) !== FALSE)
{
// Set a local flag so we can display different messages in our template.
$this->template->local = TRUE;
}
// HTTP Status code.
$this->request->status = 404;
}
public function action_503()
{
$this->template->title = 'Maintenance Mode';
$this->request->status = 503;
}
public function action_500()
{
$this->template->title = 'Internal Server Error';
$this->request->status = 500;
}
} // End of Error_handler
我真的看不出我哪里做错了。提前感谢您的帮助。
最佳答案
首先,您需要确保正在加载您的模块,方法是将其包含在 application/bootstrap.php 文件的模块部分中,如下所示
Kohana::modules(array(
'my'=>MODPATH.'my'
)
);
您提到直接访问错误处理程序 Controller 的 url 会触发 404 错误,这让我认为您的模块尚未加载。
我还建议进行更多更改。
http_response_exception.php 不需要扩展 Kohana_Exception,因为这个类不是异常,而是异常处理程序。按照同样的思路,更合适的类名可能是 Exception_Handler,因为该类不代表异常,而是处理它们。其次,由于您命名此文件的方式,它应该位于 modules/my/classes/http/response/exception.php 中。除此之外,这个类的代码看起来没问题。
同样,由于您对 Controller 的命名方式,它的定位和命名方式应该有所不同。将其移至 modules/my/classes/controller/error/handler.php
请记住,根据 http://kohanaframework.org/3.2/guide/kohana/conventions,类名中的下划线表示新目录
最后,我认为您不需要在此处扩展 Kohana_Core 类,只需注册您自己的自定义异常处理程序即可。您可以在应用程序的引导文件或模块的 init 文件中使用以下通用代码注册自定义异常处理程序:
set_exception_handler(array('Exception_Handler_Class', 'handle_method'));
这是我使用的客户异常处理程序,与您的非常相似:
<?php defined('SYSPATH') or die('No direct script access.');
class Exception_Handler {
public static function handle(Exception $e)
{
$exception_type = strtolower(get_class($e));
switch ($exception_type)
{
case 'http_exception_404':
$response = new Response;
$response->status(404);
$body = Request::factory('site/404')->execute()->body();
echo $response->body($body)->send_headers()->body();
return TRUE;
break;
default:
if (Kohana::$environment == Kohana::DEVELOPMENT)
{
return Kohana_Exception::handler($e);
}
else
{
Kohana::$log->add(Log::ERROR, Kohana_Exception::text($e));
$response = new Response;
$response->status(500);
$body = Request::factory('site/500')->execute()->body();
echo $response->body($body)->send_headers()->body();
return TRUE;
}
break;
}
}
}
