laravel 无法在控制器构造函数中获取会话

发布于01月09日

在new laravel中，我无法在构造函数中获取会话.为什么？

public function __construct()
{
    dd(Session::all()); //this is empty array
}

and then below

public function index()
{
    dd(Session::all()); //here works
}

In old laravel i remember there was not this problem. something changed?

推荐答案

You can't do it by default with Laravel 5.3. But when you edit you Kernel.php and change protected $middleware = []; to the following it wil work.

protected $middleware = [
    \Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode::class,
    \Illuminate\Session\Middleware\StartSession::class,
    \Illuminate\View\Middleware\ShareErrorsFromSession::class,
];

protected $middlewareGroups = [
    'web' => [
        \App\Http\Middleware\EncryptCookies::class,
        \Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,

        \App\Http\Middleware\VerifyCsrfToken::class,
        \Illuminate\Routing\Middleware\SubstituteBindings::class,
    ],
    'api' => [
        'throttle:60,1',
        'bindings',
    ],
];

希望这能奏效！
