laravel 5.2 auth登录和csrf无法正常工作

我在这里遇到了一个大问题我的应用程序运行顺利，直到有一天我的AUTH大楼不再工作了 . 它一直在告诉令牌不匹配错误，但当我尝试禁用CSRF时，登录总是会将我重定向回登录页面，如AUTH false . 有人可以帮助我，我在这里失踪了吗？我正在使用Laravel 5.2

route code:

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

    Route::get('/login', 'Auth\AuthController@getLogin');
    Route::post('/login', 'Auth\AuthController@postLogin');
    Route::get('/home', 'AdminController@index');
});

登录后我得到奇怪的重定向，无论用户/密码是否正确 .
