Laravel 角色中间件，未找到类角色

Laravel RoleMiddleware, class role not found

提问by Devon

I'm trying to add a simple middleware to check if a user matches a role. I'm running into an issue when I use the middleware, I get an Exception:

我正在尝试添加一个简单的中间件来检查用户是否与角色匹配。使用中间件时遇到问题，出现异常：

ReflectionException: class role does not exist

ReflectionException: 类角色不存在

I do not attempt to call a class named role so I assume this is happening magically in Laravel somewhere.

我不会尝试调用名为 role 的类，所以我认为这在 Laravel 的某个地方神奇地发生了。

My middleware:

我的中间件：

class RoleMiddleware
{
    /**
     * Run the request filter.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @param  string  $role
     * @return mixed
     */
    public function handle($request, Closure $next, $role)
    {
        if (! $request->user()->is($role)) {
            return redirect('/login');
        }

        return $next($request);
    }

}

In the users table, I have a role field and in the User model I have:

在用户表中，我有一个角色字段，在用户模型中我有：

/**
 * Check if a user is a certain role
 *
 * @param $role
 * @return bool
 */
function is($role) {
    return ($this->role == $role);
}

The route group:

路线组：

Route::group(['prefix' => 'support', 'middleware' => ['role:admin', 'web']], function() {
        Route::get('threads', 'ThreadController@index');
});

In Http/Kernel.php:

在 Http/Kernel.php 中：

protected $middlewareGroups = [
    'web' => [
        \App\Http\Middleware\EncryptCookies::class,
        \Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,
        \Illuminate\Session\Middleware\StartSession::class,
        \Illuminate\View\Middleware\ShareErrorsFromSession::class,
        \App\Http\Middleware\VerifyCsrfToken::class,
    ],

    'role' => [
        RoleMiddleware::class,
    ],
];

Anyone have any ideas on what could be causing this ReflectionException?

任何人都对可能导致此 ReflectionException 的原因有任何想法？

This came down to two problems:

这归结为两个问题：

1. $middlewareGroupsmay not allow for parameters. (Needs to be confirmed) Dropping RoleMiddlewaredown to $routeMiddlewaregot rid of the exception.

2. Having 'web' after 'role:admin' resulted in a null$request->user(). So for future users, you may need to consider placement of your middleware and a check to see if $request->user()is null.

1. $middlewareGroups可能不允许参数。（需要确认）RoleMiddleware下拉$routeMiddleware去掉异常。

2. 在 'role:admin' 之后加上 'web' 会导致null$request->user(). 因此，对于未来的用户，您可能需要考虑放置中间件并检查是否$request->user()为空。

Hope this helps someone else.

希望这对其他人有帮助。

For Spatie/Laravel-Permissions to work properly we have to register the two route middleware (roleand permission) in app/Http/Kernel.phpas follows, along with the other two auth middleware:

为了让 Spatie/Laravel-Permissions 正常工作，我们必须按如下方式注册两个路由中间件 (role和permission) app/Http/Kernel.php，以及另外两个 auth 中间件：

/**
 * The application's route middleware.
 *
 * These middleware may be assigned to groups or used individually.
 *
 * @var array
 */
protected $routeMiddleware = [
    'auth' => \Illuminate\Auth\Middleware\Authenticate::class,
    'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,
    'permission' => \Spatie\Permission\Middlewares\PermissionMiddleware::class,
    'role' => \Spatie\Permission\Middlewares\RoleMiddleware::class,
];

In Http/Kernel.php, you need to include the full path to RoleMiddleware. E.g.:

在 中Http/Kernel.php，您需要包含到RoleMiddleware. 例如：

...
'role' => [
    \App\Http\Middleware\RoleMiddleware::class,
],
...

Try to change this

尝试改变这一点

Route::group(['prefix' => 'support', 'middleware' => ['role:admin', 'web']], function() {
    Route::get('threads', 'ThreadController@index');
});

to

到

Route::group(['prefix' => 'support', 'middlewareGroups' => ['role:admin', 'web']], function() {
    Route::get('threads', 'ThreadController@index');
});

I'm a beginner in laravel i was facing this same problem and fixed by changing the name from middleware to "your-own-middelware-name".

我是 laravel 的初学者，我遇到了同样的问题，并通过将名称从中间件更改为“您自己的中间件名称”来解决。
