Laravel 5.3 auth 登陆不成功？

@mitoop
我改成了这样 还是有问题

// Login Routes...
Route::get('login', ['as' => 'login', 'uses' => 'Auth\LoginController@showLoginForm']);
Route::post('login', ['as' => 'login.post', 'uses' => 'Auth\LoginController@login']);
Route::group(['middleware' => ['web']], function() {
Route::post('logout', ['as' => 'logout', 'uses' => 'Auth\LoginController@logout']);

// Registration Routes...
Route::get('register', ['as' => 'register', 'uses' => 'Auth\RegisterController@showRegistrationForm']);
Route::post('register', ['as' => 'register.post', 'uses' => 'Auth\RegisterController@register']);
// Password Reset Routes...
Route::get('password/reset', ['as' => 'password.reset', 'uses' =>   'Auth\ForgotPasswordController@showLinkRequestForm']);
Route::post('password/email', ['as' => 'password.email', 'uses' => 'Auth\ForgotPasswordController@sendResetLinkEmail']);
Route::get('password/reset/{token}', ['as' => 'password.reset.token', 'uses' =>    'Auth\ResetPasswordController@showResetForm']);
Route::post('password/reset', ['as' => 'password.reset.post', 'uses' => 'Auth\ResetPasswordController@reset']);
