Auth::user() 返回 null [英] Auth::user() returns null

问题描述

我使用 Laravel 5.2，中间件有问题.代码在routes.php

<前>使用 IlluminateContractsAuthAccessGate;Route::group(['middleware' => 'web'], function () {路线::认证();Route::get('/', 'HomeController@index');});Route::group(['prefix'=>'admin', 'middleware' => 'admin'], function(){路由::get('/', function(){返回视图('admin.index');});路线::获取('/用户'，功能(){返回视图('admin.user');});});

内核.php:

<前>受保护的 $routeMiddleware = [...'admin' => AppHttpMiddlewareAdminPanel::class，];

AdminPanel.php

<前>命名空间 AppHttpMiddleware;使用闭包；使用 IlluminateSupportFacadesAuth;使用 AppRole;类管理面板{公共函数句柄($request, Closure $next){$user = Auth::user();dd($用户);如果($用户){$role = Role::whereName('admin')->first();if($user->hasRole($role)){返回 $next($request);}}返回重定向('/')；}

所以，

$user = Auth::user()

总是返回 null.感谢您的建议！

解决方案

任何使用 Auth() 的路由都必须封装在 web 中间件中.您已经接近了，只需将您的 Route::group(['prefix' => 'admin'], ...) 移动到上面的组中即可.

Route::group(['middleware' => 'web'], function () {路线::认证();Route::get('/', 'HomeController@index');//移到这里将确保会话、csrf 等都包含在所有这些路由中Route::group(['prefix'=>'admin', 'middleware' => 'admin'], function(){路由::get('/', function(){返回视图('admin.index');});路线::获取('/用户'，功能(){返回视图('admin.user');});});});

I use Laravel 5.2 and have a problem with middleware. There is the code in the routes.php

    use IlluminateContractsAuthAccessGate;


    Route::group(['middleware' => 'web'], function () {

        Route::auth();

        Route::get('/', 'HomeController@index');
    });


    Route::group(['prefix'=>'admin',  'middleware' => 'admin'], function(){
        Route::get('/', function(){
            return view('admin.index');
        });
        Route::get('/user', function(){
            return view('admin.user');
        });
    });

Kernel.php:

    protected $routeMiddleware = [
    ...
     'admin' => AppHttpMiddlewareAdminPanel::class,
    ];

AdminPanel.php

    namespace AppHttpMiddleware;


    use Closure;
    use IlluminateSupportFacadesAuth;
    use AppRole;

    class AdminPanel
    {
        public function handle($request, Closure $next)
        {
            $user = Auth::user();
            dd($user);

            if($user){
                $role = Role::whereName('admin')->first();
                if($user->hasRole($role)){
                    return $next($request);
                }
            }
            return redirect('/');
        }

So,

$user = Auth::user()

always return null. Thanks for suggestions!

解决方案

Any route that uses Auth() must be encapsulated in the web middleware. You're close, just move your Route::group(['prefix' => 'admin'], ...) into the group above.

Route::group(['middleware' => 'web'], function () {

    Route::auth();

    Route::get('/', 'HomeController@index');

    // Moving here will ensure that sessions, csrf, etc. is included in all these routes
    Route::group(['prefix'=>'admin',  'middleware' => 'admin'], function(){
        Route::get('/', function(){
            return view('admin.index');
        });

        Route::get('/user', function(){
            return view('admin.user');
        });
    });
});
