问题描述

我读到 AppError 类现在是为了向后兼容，应该使用 Exceptions 来代替.如何为 404 错误或完全自定义错误等内容创建自定义错误页面?

试试这个:

/app/Config/core.php

异常渲染需要设置为AppExceptionRender.示例:

Configure::write('Exception', array('处理程序' =>'ErrorHandler::handleException','渲染器' =>'AppExceptionRenderer','日志' =>真的));

/app/Controller/ErrorsController.php

class ErrorsController 扩展 AppController {公共 $name = '错误';公共函数 beforeFilter() {父::beforeFilter();$this->Auth->allow('error404');}公共函数 error404() {//$this->layout = 'default';}}

/app/Lib/Error/AppExceptionRenderer.php

App::uses('ExceptionRenderer', 'Error');类 AppExceptionRenderer 扩展 ExceptionRenderer {公共函数 notFound($error) {$this->controller->redirect(array('controller' => 'errors', 'action' => 'error404'));}}

/app/View/Errors/error404.ctp

<h2>404 错误 - 页面未找到</h2>

在需要的地方插入:throw new NotFoundException();

I read that the AppError class is now for backwards compatibility and that Exceptions should be used instead. How does one go about creating custom error pages for things like 404 errors, or completely custom errors?

Try this:

/app/Config/core.php

Exception render need to set as an AppExceptionRender. Example:

Configure::write('Exception', array(
        'handler' => 'ErrorHandler::handleException',
        'renderer' => 'AppExceptionRenderer',
        'log' => true
));

/app/Controller/ErrorsController.php

class ErrorsController extends AppController {
    public $name = 'Errors';

    public function beforeFilter() {
        parent::beforeFilter();
        $this->Auth->allow('error404');
    }

    public function error404() {
        //$this->layout = 'default';
    }
}

/app/Lib/Error/AppExceptionRenderer.php

App::uses('ExceptionRenderer', 'Error');

class AppExceptionRenderer extends ExceptionRenderer {

    public function notFound($error) {
        $this->controller->redirect(array('controller' => 'errors', 'action' => 'error404'));
    }
}

/app/View/Errors/error404.ctp

<div class="inner404">
    <h2>404 Error - Page Not Found</h2>
</div>

Insert it where you need: throw new NotFoundException();
