Laravel Multi Token

Introduction

This package provides a simple solution for give multiple token to your application's users. This solution is similar to Laravel's TokenGuard class.

This package is for Laravel 5.5 and above.

Installation

You can install the package via composer using:

composer require mayoz/laravel-tokens

The service provider will automatically get registered for Laravel 5.5 and above versions. If you want you can add the service provider in config/app.php file:

'providers' => [
    // ...
    Mayoz\Token\TokenServiceProvider::class,
];

If you are going to make changes the default migration, you can publish the migration file with:

php artisan vendor:publish --provider="Mayoz\Token\TokenServiceProvider" --tag="laravel-tokens-migrations"

Then, you can create the tokens table by running the migrations:

php artisan migrate

You can publish the config file with:

php artisan vendor:publish --provider="Mayoz\Token\TokenServiceProvider" --tag="laravel-tokens-config"

If you need you are free to change your config file.

Implementation

After installation, you can implement the new feature for your application.

Add the Mayoz\Token\HasToken trait to your App\User model. This trait will provide a few helper methods to your model which allow you to inspect the authenticated user's tokens:

<?php

namespace App;

use Mayoz\Token\HasToken;
use Illuminate\Notifications\Notifiable;
use Illuminate\Foundation\Auth\User as Authenticatable;

class User extends Authenticatable
{
    use HasToken, Notifiable;
    
    // ...
}

And finally, you will add the new guard to your application. Open the config/auth.php file and apply following changes:

  'guards' => [
        // ...

        'api' => [
            'driver' => 'multi-token',
            'provider' => 'tokens',
        ],
    ],

    'providers' => [
        // ...

        'tokens' => [
            'driver' => 'eloquent',
            'model' => Mayoz\Token\Token::class,
        ],
    ],

Congratulations!

Usage

When you need it (after login or any actions later), use the helper function to create a new token.

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class TokenController
{
     public function __invoke(Request $request)
     {
         $token = $request->user()->generateToken();
         
         return $token;
     }
}

By default tokens never expire if you do not pass the lifetime when generation. For define expiration, you can pass the time period parameter (in minutes) to generateToken method.

Generate a new token of 10 minutes life with:

$token = $request->user()->generateToken(10);

The token are not refreshed, token will die when expired. The authentication attempts with expired token will fail.

The authentication process is similar to that of the standard Laravel api_token flows:

The token guard is looking for the token:

1. Firstly looking the URL for parameter ?api_token=XXX
2. If not exists token, looking the header for Authorization: Bearer XXX

Finally, if you need the current token model information underlying the authentication process, you can use the token method.

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class UserController
{
     public function __construct()
     {
          $this->middleware('auth:api');
     }
     
     public function __invoke(Request $request)
     {
         return [
             'user' => $request->user(),
             'token' => $request->token(),
         ];
     }
}

Token Generator

By default, the generated token is a string of random 36 chars. If you want to create more meaningful (such as uuid4) tokens, you are free to change the generator method.

Let's make change to generate of uuid4 string. Open the app/Providers/AuthServiceProvider file and apply the additions:

<?php

namespace App\Providers;

use Mayoz\Token\Generator;
// ...

class AuthServiceProvider extends ServiceProvider
{
    // ...

    /**
     * Register any authentication / authorization services.
     *
     * @return void
     */
    public function boot()
    {
        // ...

        Generator::extend(function () {
            return \Ramsey\Uuid\Uuid::uuid4()->toString();
        });
    }
}

If there is no ramsey/uuid package in your application, you can install with:

composer require ramsey/uuid

Cheers.
