Laravel 5.2用户登录由于某种原因重定向回登录

Question

I have a Laravel 5.2 app and have used the artisan make:auth command. Everything was generated correctly, I changed my table name and managed to register. I then tried to login but I'm continually sent back to the login page. If I put incorrect credentials in on purpose, I get an error so I know my credentials are correct and that Laravel is communicating with the database. I just have no idea why I keep getting back to the login page. Can anyone help? I have posted my routes below:

Route::auth();


Route::group(['middleware' => 'auth'], function () {
    Route::post('entity/process', 'EntityController@process');
    Route::get('entity/form/{subCategoryID}/{id?}', 'EntityController@viewForm');
    Route::get('entity/delete/{id}', 'EntityController@delete');
    Route::get('/viewList/{masterCategoryID}/{subCategoryID}', 'EntityController@viewList');
    Route::get('/viewCategories', 'MasterCategoryController@viewAll');

  Route::get('/', 'MasterCategoryController@viewAll');
});

Answer 1

Solution 1 : Change this variable in App\\Http\\Controllers\\Auth\\AuthController

protected $redirectAfterLogout = '/login'

Solution 2 : Write your own customLogout method in AuthController. Then override default logout route like this

Route::auth();
Route::get('logout', 'Auth\AuthController@customLogout'); 

Answer 2

After investigating further I found that the database ID field for my users table was null and was not set to auto increment. I changed it to 1 and enabled auto increment then everything worked as expected. Thanks for everyone's help.
