Question

无论我做什么，我都无法将404页面绑定到Laravel的处理程序。

这就是我的handler.php的样子：

//app/Exceptions/handler.php
public function render($request, Exception $e)
    {   
        if($this->isHttpException($e))
        {

            switch ($e->getStatusCode()) {
                // not found
                case 404:
                    return \Response::view('errors.404',404);
                break;
                // internal error
                case '500':
                    return \Response::view('errors.500',500);   
                break;

                default:
                    return $this->renderHttpException($e);
                break;
            }
        }
        else
        {
            return parent::render($request, $e);
        }
    }

在我的控制器中，我渲染视图：

render view($request)

其中$ request是uri。

我在/ views / errors /下添加了404.blade.php，但仍然得到了Laravel的标准调试错误页面：糟糕，看起来出了问题。

转储 $ this-＆gt; isHttpException（$ e）返回false bolean

这是整个日志

Answer 1

除了在views/errors中创建一些模板文件之外，您不必编写任何代码，例如

    laravel/resources/views/errors/404.blade.php
    laravel/resources/views/errors/500.blade.php
    laravel/resources/views/errors/403.blade.php

Laravel可以自动渲染它们。

只要您想使用Laravel默认视图/错误目录来存储自定义错误视图，就应该在app / Exceptions / handler.php中调用isHttpException（）方法。

    /**
     * Render an exception into an HTTP response.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Exception  $e
     * @return \Illuminate\Http\Response
     */
    public function render($request, Exception $e)
    {
        if ($this->isHttpException($e))
        {
            switch ($e->getStatusCode()) {
                // not found
                case 404:
                  //whatever you want to do with this exception
                  return $this->renderHttpException($e); 
                break;
                // internal error
                case '500':
                  //whatever you want to do with this exception
                  return $this->renderHttpException($e); 
                break;

                default:
                    return $this->renderHttpException($e);
                break;
            }
        }
        else
        {
            return parent::render($request, $e);
        }
    }

为Laravel 5
