如何在 laravel 8 中创建带有变量的自定义错误页面
How to create a custom error page with variables in laravel 8
问:
大家早上好,如何在 laravel 8 中创建带有变量的自定义错误页面?因此,我想显示一个带有 @extend('layouts.app') 的错误页面,在此 layouts.app 中,我给出了一个变量,例如 $general 来显示 generals 表中的数据。
我已经尝试了下面的代码,但结果仍然是 Undefined variable: general。
异常\处理程序.php
<?php
namespace App\Exceptions;
use App\Models\General;
use Illuminate\Foundation\Exceptions\Handler as ExceptionHandler;
use Throwable;
use Exception;
use Illuminate\Support\Arr;
use Illuminate\Auth\AuthenticationException;
class Handler extends ExceptionHandler
{
/**
* A list of the exception types that are not reported.
*
* @var array
*/
protected $dontReport = [
//
];
/**
* A list of the inputs that are never flashed for validation exceptions.
*
* @var array
*/
protected $dontFlash = [
'current_password',
'password',
'password_confirmation',
];
/**
* Register the exception handling callbacks for the application.
*
* @return void
*/
public function register()
{
$this->reportable(function (Throwable $e) {
//
});
}
protected function unauthenticated($request, AuthenticationException $exception)
{
if ($request->expectsJson()) {
return response()->json(['error' => 'Unauthenticated.'], 401);
}
$guard = Arr::get($exception->guards(), 0);
$route = 'login';
if ($guard == 'admin') {
$route = 'admin.login';
}
return redirect()->route($route);
}
public function render($request, Throwable $exception)
{
if($this->isHttpException($exception)){
switch ($exception->getCode()) {
case 404:
//return redirect()->route('404');
$general = General::find(1);
return response()->view('errors.404', ['general' => $general], $exception->getCode());
break;
case 405:
return response()->view('errors.405', [], $exception->getCode());
break;
case 500:
return response()->view('errors.500', [], $exception->getCode());
break;
}
}
return parent::render($request, $exception);
}
}
错误\404.刀片.php
@extends('layouts.front')
@section('title', __('Not Found'))
@section('code', '404')
@section('message', __('Not Found'))
在 Laravel 8 错误页面中添加变量的正确方法是什么?谢谢:)

可以创建自己的服务提供程序(或仅使用 App\Providers\AppServiceProvider)
在引导方法中寄存 View::composer,它将侦听错误页面视图
/**
* Bootstrap services.
*
* @return void
*/
public function boot()
{
// Using closure based composers...
View::composer('errors::404', function ($view) {
$general = General::find(1);
$view->with('general', $general);
});
}
您也可以使用通配符“errors::*”
