为 Laravel 5 创建自定义 404 视图答案

【问题标题】：Creating a custom 404 view for Laravel 5为 Laravel 5 创建自定义 404 视图
【发布时间】：2015-08-20 22:04:09
【问题描述】：

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，我像这样渲染视图：

render view($request)

其中 $request 是 uri。

我在 /views/errors/ 下添加了 404.blade.php，但仍然得到 Laravel 的标准调试错误页面：哎呀，好像出了点问题。

转储 $this->isHttpException($e) 返回 false 布尔值

这是整个日志

【问题讨论】：

您能否提供日志中的完整错误消息？
我已经添加了日志
如果您尝试返回 dd('404 error') 而不是视图，它是否工作正常？
默认路径是views/errors，不是view/errors
@Alexandros, dd('404 error');返回“404 错误”

【解决方案1】：

一旦你想使用 Laravel 默认的视图/错误目录来存储你的自定义错误视图，你应该在 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);
        }
    }

【讨论】：

这是我的 handler.php 的样子，但不起作用
这不像你的问题中的 handler.php.. :/ 尝试用这个替换你的，看看是否有效。

【解决方案2】：

您无需编写任何代码，只需在 views/errors 中创建一些模板文件，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。

【讨论】：

我在帖子中确实提到我在视图/错误中添加了 404.blade.php
在调试模式下，它显示错误描述页面而不是您的错误页面，尝试更改您的.env文件中的APP_DEBUG=false，或您的config/app.php文件中的'debug' => false,。
