laravel 5.2 取 Auth::user() 的值一直爲NULL

由於 laravel 5.2 更新了路由策略.........

因此全部路由都應該寫在中間件web的下面

Route::group(['middleware' => 'web'], function () {
     // your routes
 });

固然也能夠把web中間件放到全局的中間件裏面去 ，在app/Http/Kernel.php文件中，而後把web中間件刪掉

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