类 Illuminate\Routing\Middleware\Rolemiddleware 不存在

Question

我正在使用 laravel ，当我尝试在路由器中注入中间件时遇到一些错误

我的路由器代码

<?php

Route::get('role',[
    'middleware' => 'Role:editor',
    'uses' => 'TestController@index',
])->middleware('role');

?>

kernal.php

protected $routeMiddleware = [
        'auth' => \App\Http\Middleware\Authenticate::class,
        'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,
        'can' => \Illuminate\Foundation\Http\Middleware\Authorize::class,
        'guest' => \App\Http\Middleware\RedirectIfAuthenticated::class,
        'throttle' => \Illuminate\Routing\Middleware\ThrottleRequests::class,
        'Age' => \App\Http\Middlware\AgeMiddleware::class,
        'Role' => \App\Http\Middlware\RoleMiddleware::class,
    ];

RoleMiddleware.php

<?php

namespace App\Http\Middleware;

use Closure;

class RoleMiddleware
{
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next, $role)
    {
        echo "Role: ".$role;
        return $next($request);
    }
}

?>

这是我的 TestController 代码：

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use App\Http\Requests;


class Firstcontroller extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {
        //
        echo '<br>First Controller';
    }

?>

我收到一个错误：类 Illuminate\Routing\Middleware\Rolemiddleware 不存在。我是 Laravel 新手并使用 Laravel 5.3。你能告诉我为什么它给我一个错误

Answer 1

在 kernal.php 中，您在单词 Middlware 中出现拼写错误

改一下

'Age' => \App\Http\Middlware\AgeMiddleware::class,
  'Role' => \App\Http\Middlware\RoleMiddleware::class,

到

'Age' => \App\Http\Middleware\AgeMiddleware::class,
'Role' => \App\Http\Middleware\RoleMiddleware::class,
