How to add a custom User Provider in Laravel 5.4

Asked by: Bul Ikana

I have a Laravel 5.4 app, in which I have to authenticate my admin users from an external API, which when successfully logged in it returns a JSON with user information.

I am creating a custom guard to make this:

    'guards' => [
        'web' => [
            'driver' => 'session',
            'provider' => 'users'
        ],

        'custom' => [
            'driver' => 'session',
            'provider' => 'customusers'
        ],

        'api' => [
            'driver' => 'token',
            'provider' => 'users',
        ],
    ],

and this is my custom provider:

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

    'customusers' => [
        'driver' => 'jsonresponse',
        'model' => App\Admin::class,
    ]
],

After that, I am not sure how to continue. I've read some tutorials like the one from George Buckingham, and I have created a custom User provider (Right now I just need it to extend from EloquentUserProvider, eventually I will override some functions to connect to the API)

<?php

namespace App\Providers;

use Illuminate\Auth\EloquentUserProvider;
use Illuminate\Support\Str;

class CustomUserProvider extends EloquentUserProvider { 

}

then registered it both in App\Providers\AuthServiceProvider

public function boot()
{
    $this->registerPolicies();

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

and in config/app.php

'providers' => [

    // Lots of other providers

    // Own providers
    App\Providers\CustomUserProvider::class,
],

But after that, I get the following error:

Argument 1 passed to Illuminate\Auth\EloquentUserProvider::__construct() must be an instance of Illuminate\Contracts\Hashing\Hasher, instance of Illuminate\Foundation\Application given, called in /var/www/public/iberorides/vendor/laravel/framework/src/Illuminate/Foundation/Application.php on line 612 and defined

If I override the constructor of my CustomUserProvider and change the params in the closure in AuthServiceProvider, I get the following error:

Argument 1 passed to Illuminate\Foundation\Application::bootProvider() must be an instance of Illuminate\Support\ServiceProvider, instance of App\Providers\IberoUserProvider given, called in /var/www/public/iberorides/vendor/laravel/framework/src/Illuminate/Foundation/Application.php on line 771 and defined

This makes me think I am not doing things the right way.

Could someone put me in the right direction?

Thank you so much.
