基于此文档,我实现了一个捕获所有路由到错误页面的路由。

这是我的最后一条路线bootstrap.php

Route::set('default', '<path>', array('path' => '.+'))
    ->defaults(array(
        'controller' => 'errors',
        'action'     => '404',
    ));

但是,当我尝试转到不存在的页面时,我不断抛出此异常

Kohana_Exception [ 0 ]:未传递所需的路由参数:路径

如果我将该<path>段设为可选(即用括号括起来),那么它似乎只是加载了home路由,即......

Route::set('home', '')
    ->defaults(array(
        'controller' => 'home',
        'action'     => 'index',
    ));

首先定义家乡路由。

我像这样执行我的主要请求

$request = Request::instance();


try {

    // Attempt to execute the response
    $request->execute();

} catch (Exception $e) {


   if (Kohana::$environment === Kohana::DEVELOPMENT) throw $e;

    // Log the error
    Kohana::$log->add(Kohana::ERROR, Kohana::exception_text($e));

    // Create a 404 response
    $request->status = 404;
    $request->response = Request::factory(Route::get('default')->uri())->execute();

}

$request->send_headers();
echo $request->response;

这意味着 404 标头被发送到浏览器,但我假设通过将请求发送到捕获所有路由,那么它应该显示在我的错误控制器中设置的 404 错误。

<?php defined('SYSPATH') or die('No direct script access.');

class Controller_Errors extends Controller_Base {

    public function before() {
        parent::before();
    }

    public function action_404() {


        $this->bodyClass[] = '404';

        $this->internalView = View::factory('internal/not_found');

        $longTitle = 'Page Not Found';

        $this->titlePrefix = $longTitle;


    }
}

为什么它不会显示我的 404 错误页面?

对于我的项目,我从未为 404 指定任何特定的分隔路由。当找不到合适的路由时,我只是捕获路由引发的异常。

以下是我如何处理我在 Kohana 中发现的所有类型的异常。我希望它会帮助你。

try
{
    try
    {
        $request = Request::instance();
        $request->execute();
    }
    catch (ReflectionException $e)
    {
        Kohana::$log->add(Kohana::ERROR_404, Kohana::exception_text($e));

        if (!IN_PRODUCTION)
        {
        throw $e;
        }

        $request->response = Request::factory('err/404')->execute();
    }
    catch (Exception404 $e)
    {
        Kohana::$log->add(Kohana::ERROR_404, Kohana::exception_text($e));

        if (!IN_PRODUCTION)
        {
        throw $e;
        }

        $request->response = Request::factory('err/404')->execute();
    }
    catch (Kohana_Request_Exception $e)
    {
        Kohana::$log->add(Kohana::ERROR_404, Kohana::exception_text($e));

        if (!IN_PRODUCTION)
        {
        throw $e;
        }

        header('Content-Type: text/html; charset='.Kohana::$charset, TRUE, 404);
        echo Request::factory('err/404')->send_headers()->execute()->response;
        exit;
    }
    catch (exception $e)
    {
        Kohana::$log->add(Kohana::ERROR, Kohana::exception_text($e));

        if (!IN_PRODUCTION)
        {
        throw $e;
        }

        $request->status = 500;
        $request->response = Request::factory('err/500')->execute();
    }
}
catch (exception $e)
{
        if (!IN_PRODUCTION)
        {
            throw $e;
        }
        echo '<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
        "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
        <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">

        <body>
        here is the message that everything is veeeery bad
        </body>
        </html>';
        exit;
}

异常404:

class Kohana_Exception404 extends Kohana_Exception
{
    public function __construct($message = 'error 404', array $variables = NULL, $code = 0)
    {
        parent::__construct($message, $variables, $code);
    }
 }

啊,这个我想通了。

这条线...

$request->response = Request::factory(Route::get('default')->uri())->execute();

正在设置对结果的响应Route::get('default')->uri()。进一步看,我意识到它将返回一个空字符串,它将与home上面的路由匹配。我觉得很傻......
