I am pretty new in PHP and Laravel framework and I am going crazy trying to implement the following task.
I am trying to follow this tutorial to implement a custom user provider:
https://blog.georgebuckingham.com/laravel-52-auth-custom-user-providers-drivers/
I am using Larave 5.3 version.
I briefly expain what I need: my Laravel application is only a front end application, all the business logic, included the user authentication, is performed by a Java back end application that exposes REST web services.
Performing a call to:
http://localhost:8080/Extranet/login
and passing username and password as basic authentication I obtain a JSON response like this that represent the logged user:
{
"userName": "Painkiller",
"email": "painkiller@gmail.com",
"enabled": true
}
So, in my Laravel application, I have to perform this call and then parse the previous returned JSON object to generate the authenticated object into the front end application session.
I think that the previous custom user provider is the neater and most natural solution to do it, but I am obtaining an erro, I will explain the situation.
I have implemented all the 4 steps of the previous tutorial and I think that I have correctly replaced the user provider with my custom user provider.
Aftere these implementation steps I performed this command:
php artisan make:auth
to generate te view and the routes related to the Laravel login system. I expect that it is using the custom user provider defined by me.
So I have these routes:
$ php artisan route:list
+--------+----------+------------------------+----------+------------------------------------------------------------------------+--------------+
| Domain | Method | URI | Name | Action | Middleware |
+--------+----------+------------------------+----------+------------------------------------------------------------------------+--------------+
| | GET|HEAD | / | | App\Http\Controllers\LoginBetriviusController@index | web |
| | GET|HEAD | api/user | | Closure | api,auth:api |
| | POST | doLogin | | App\Http\Controllers\LoginBetriviusController@doLogin | web |
| | GET|HEAD | home | | App\Http\Controllers\HomeController@index | web,auth |
| | POST | login | | App\Http\Controllers\Auth\LoginController@login | web,guest |
| | GET|HEAD | login | login | App\Http\Controllers\Auth\LoginController@showLoginForm | web,guest |
| | POST | logout | logout | App\Http\Controllers\Auth\LoginController@logout | web |
| | POST | password/email | | App\Http\Controllers\Auth\ForgotPasswordController@sendResetLinkEmail | web,guest |
| | GET|HEAD | password/reset | | App\Http\Controllers\Auth\ForgotPasswordController@showLinkRequestForm | web,guest |
| | POST | password/reset | | App\Http\Controllers\Auth\ResetPasswordController@reset | web,guest |
| | GET|HEAD | password/reset/{token} | | App\Http\Controllers\Auth\ResetPasswordController@showResetForm | web,guest |
| | GET|HEAD | register | register | App\Http\Controllers\Auth\RegisterController@showRegistrationForm | web,guest |
| | POST | register | | App\Http\Controllers\Auth\RegisterController@register | web,guest |
+--------+----------+------------------------+----------+------------------------------------------------------------------------+--------------+
As you can see there are the standard login routes. I think that now it have to use my custom user provider (the one that call my REST web service) instead the standard one.
I run the application using the statment:
php artisan serve
It starts without no error, then I access to this URL:
http://localhost:8000/login
and the login page is correctly displayed.
Then i insert the credential (e-mail and password) but when I submit the login form I obtain this error message:

Why? What could be wrong? How can I try to ix this issue?
I am not into Laravel but searching online information about Laravel login and the problem to the missing LogAuthenticationAttempt class I have fount this SO post:
Log failed login attempts with Laravel 5.2
Maybe it is a similar problem but I am not understanding it it could be the same situation and how to solve it.
What can I do?
Try running the command php artisan event:generate and it will generate any events in the $listen variable in your EventServiceProvider.php file.
