Laravel 中间件在经过身份验证的用户中返回 null

Question

我试图阻止某些用户访问某些路由。我创建了一个名为 CheckUserRole 的中间件。但当我尝试从登录用户获取任何数据时，我总是得到空响应，这与我在视图中请求用户 ID 时不同。

我正在使用 PHP 8.2.8 和 laravel 10

这是我的 web.php 文件

<?php

use Illuminate\Support\Facades\Route;

use App\Http\Controllers\HomeController;
use App\Http\Controllers\Admin\PsychologicalTestController;
use App\Http\Controllers\Admin\ProfileController;
use App\Http\Controllers\Admin\TaskController;
use App\Http\Controllers\Admin\CapsuleController;

/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider and all of them will
| be assigned to the "web" middleware group. Make something great!
|
*/

Route::redirect('/', '/login');

// Authentication routes
Route::middleware(['auth',])->group(function () {
    Route::get('/home', [HomeController::class, 'index'])->name('home');
});
Route::middleware(['auth'])->group(function () { 

    // Admin routes
    Route::middleware(['check.user.role'])->prefix('admin')->group(function () {
        Route::resource('psycological-test', PsychologicalTestController::class);
        Route::resource('profile', ProfileController::class);
        Route::resource('task', TaskController::class, ['as' => 'admin']);
        Route::resource('capsule', CapsuleController::class);
    });

});

更令我惊讶的是，我决定只包含 Auth 中间件，并尝试用 dd 来破坏它，但是在执行视图时，它会正常打开，就好像它没有进入中间件一样。

在我的 web.php 中测试

Route::group(['middleware' => 'auth'], function () {
    Route::group(['prefix' => 'admin'], function () {
        Route::resource('capsule', CapsuleController::class);
    });
}); 

App\Http\Middleware\Authenticate.php

    /**
     * Get the path the user should be redirected to when they are not authenticated.
     */
    protected function redirectTo(Request $request): ?string
    {
        dd($request);
        // return $request->expectsJson() ? null : route('login');
    }

我尝试移动内核文件中的中间件，但没有成功。

内核.php

<?php

namespace App\Http;

use Illuminate\Foundation\Http\Kernel as HttpKernel;

class Kernel extends HttpKernel
{
    /**
     * The application's global HTTP middleware stack.
     *
     * These middleware are run during every request to your application.
     *
     * @var array<int, class-string|string>
     */
    protected $middleware = [
        // \App\Http\Middleware\TrustHosts::class,
        \App\Http\Middleware\TrustProxies::class,
        \Illuminate\Http\Middleware\HandleCors::class,
        \App\Http\Middleware\PreventRequestsDuringMaintenance::class,
        \Illuminate\Foundation\Http\Middleware\ValidatePostSize::class,
        \App\Http\Middleware\TrimStrings::class,
        \Illuminate\Foundation\Http\Middleware\ConvertEmptyStringsToNull::class,
        \App\Http\Middleware\CheckUserRole::class,
        \App\Http\Middleware\CheckParticipantPhase::class,
        
    ];

    /**
     * The application's route middleware groups.
     *
     * @var array<string, array<int, class-string|string>>
     */
    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,
            \Illuminate\Routing\Middleware\SubstituteBindings::class,
        ],

        'api' => [
            // \Laravel\Sanctum\Http\Middleware\EnsureFrontendRequestsAreStateful::class,
            \Illuminate\Routing\Middleware\ThrottleRequests::class.':api',
            \Illuminate\Routing\Middleware\SubstituteBindings::class,
        ],
    ];

    /**
     * The application's middleware aliases.
     *
     * Aliases may be used instead of class names to conveniently assign middleware to routes and groups.
     *
     * @var array<string, class-string|string>
     */
    protected $middlewareAliases = [
        'auth' => \App\Http\Middleware\Authenticate::class,
        'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,
        'auth.session' => \Illuminate\Session\Middleware\AuthenticateSession::class,
        'cache.headers' => \Illuminate\Http\Middleware\SetCacheHeaders::class,
        'can' => \Illuminate\Auth\Middleware\Authorize::class,
        'guest' => \App\Http\Middleware\RedirectIfAuthenticated::class,
        'password.confirm' => \Illuminate\Auth\Middleware\RequirePassword::class,
        'precognitive' => \Illuminate\Foundation\Http\Middleware\HandlePrecognitiveRequests::class,
        'signed' => \App\Http\Middleware\ValidateSignature::class,
        'throttle' => \Illuminate\Routing\Middleware\ThrottleRequests::class,
        'verified' => \Illuminate\Auth\Middleware\EnsureEmailIsVerified::class,
        'check.user.role' =>\App\Http\Middleware\CheckUserRole::class,
        'check.participant.phase' =>\App\Http\Middleware\CheckUserStatus::class,
        'localize'                => \Mcamara\LaravelLocalization\Middleware\LaravelLocalizationRoutes::class,
        'localizationRedirect'    => \Mcamara\LaravelLocalization\Middleware\LaravelLocalizationRedirectFilter::class,
        'localeSessionRedirect'   => \Mcamara\LaravelLocalization\Middleware\LocaleSessionRedirect::class,
        'localeCookieRedirect'    => \Mcamara\LaravelLocalization\Middleware\LocaleCookieRedirect::class,
        'localeViewPath'          => \Mcamara\LaravelLocalization\Middleware\LaravelLocalizationViewPath::class
    ];
}

最后，当我运行这个时

dd(
 auth()->id() ?? '?',
 Auth::id() ?? '?',
 $request->user()->id ?? '?',
 auth()->check(),
 get_class(auth()->guard())
);

我明白了

"?" // app/Http/Middleware/CheckUserRole.php:19
"?" // app/Http/Middleware/CheckUserRole.php:19
"?" // app/Http/Middleware/CheckUserRole.php:19
false // app/Http/Middleware/CheckUserRole.php:19
"Illuminate\Auth\SessionGuard" // app/Http/Middleware/CheckUserRole.php:19

任何提示或帮助将不胜感激。

答案是，你不能在全局中间件数组和别名数组中同时注册一个中间件。这就是 Laravel 无法正确使用它的原因。
