php – Laravel 5.2 Error In Custom Authentication

Posted by: admin July 12, 2020 Leave a comment

Questions:

I am getting error while making custom authentication for my laravel 5.2 however this code works fine on my laravel 5.1 My config/auth.php file

'providers' => [
    'users' => [
        'driver' => 'custom',
        'model' => App\User::class,
    ],

    // 'users' => [
    //     'driver' => 'database',
    //     'table' => 'users',
    // ],
],

My CustomUserProvider.php (Auth/CustomUserProvider) file

    <?php namespace App\Auth;

use Illuminate\Contracts\Auth\UserProvider;
use Illuminate\Contracts\Hashing\Hasher as HasherContract;
use Illuminate\Contracts\Auth\Authenticatable as UserContract;

class CustomUserProvider implements UserProvider {

    protected $model;

    public function __construct(UserContract $model)
    {
        $this->model = $model;
    }

    public function retrieveById($identifier)
    {

    }

    public function retrieveByToken($identifier, $token)
    {

    }

    public function updateRememberToken(UserContract $user, $token)
    {

    }

    public function retrieveByCredentials(array $credentials)
    {

    }

    public function validateCredentials(UserContract $user, array $credentials)
    {

    }

}

My CustomAuthProvider.php file

    <?php namespace App\Providers;

use App\User;
use Auth;
use App\Auth\CustomUserProvider;
use Illuminate\Support\ServiceProvider;

class CustomAuthProvider extends ServiceProvider {

    /**
     * Bootstrap the application services.
     *
     * @return void
     */
    public function boot()
    {
        $this->app['auth']->extend('custom',function()
        {

            return new CustomUserProvider();
        });
    }

    /**
     * Register the application services.
     *
     * @return void
     */
    public function register()
    {
        //
    }

}

Now this works fine in laravel 5.1 in 5.2 i am getting error like

InvalidArgumentException in CreatesUserProviders.php line 40:
Authentication user provider [custom] is not defined.
How to&Answers:

The only point is to use

$this->app['auth']->provider(... 

instead of

$this->app['auth']->extend(...

The last one is used in 5.1, the first one should be used in 5.2.

Answer:

app/Models/User.php

namespace App\Models;

use Illuminate\Foundation\Auth\User as Authenticatable;

class User extends Authenticatable {
protected $connection='conn';
protected $table='users-custom';

/**
 * The attributes that are mass assignable.

 * @var array
 */
protected $fillable = [
    'login', 'passwd'
];

 * @var array
 */

    'passwd',
];

public function getAuthPassword(){
    //your passwor field name

use Auth;
use App\Models\User;
use App\Auth\CustomUserProvider;

/**
 * Description of CustomAuthProvider

 */

class CustomUserAuthProvider extends ServiceProvider {

/**

    });
}

/**

 */
public function register()

    //
}

}

Answer:

Try by replacing the boot function as below:

public function boot()
{
    Auth::provider('custom', function($app, array $config) {
        // Return an instance of Illuminate\Contracts\Auth\UserProvider...
        return new CustomUserProvider($app['custom.connection']);
    });
}

Answer:

Replace the boot function as below:

public function boot()
    {
        Auth::provider('customUser', function($app, array $config) {
            return new CustomUserProvider($config['model']);
        });
    }
