Tutorial : Laravel 5 token based Authentication (OAuth 2.0)

PHP OAuth 2.0 Server for Laravel

Note: a fully configured project can be found on this github repo

1. Install oAuth 2.0 Plugin :

we will use the following plugin :


the easiest way to install this plugin is by using Composer .

in composer.js

add the following line (“lucadegasperi/oauth2-server-laravel”: “4.0.x@dev)” ) to require

“require”: {
“lucadegasperi/oauth2-server-laravel”: “4.0.x@dev”

to download the plugin files , in the project root run :

composer update
composer installing the new plugin files

Once composer has installed the package,

1.1 add this line of code to the providers array located in your config/app.php file:


1.2 And this lines to the aliases array:

'Authorizer' => 'LucaDegasperi\OAuth2Server\Facades\AuthorizerFacade',

1 .3 open app/Http/Kernel.php then do the following

  • Add the following line to your file in the $middleware array
  • remove the following line from the $middleware array
  • in the same file add the following item to $routeMiddleware Array
 ‘csrf’ => ‘App\Http\Middleware\VerifyCsrfToken’,
Kernel.php Content after changes

2. Setup the Database :

  1. first we need to setup database , in the project root find .env file :
DB_DATABASE=Mysql database name
DB_USERNAME=Mysql user name
DB_PASSWORD=Mysql password

2. then Run the following command to publish this package configuration and migrations.

php artisan vendor:publish

the previous command will create all migration files that the plugin needs .

3. Run this command to apply migration files on the database

php artisan migrate

3. Configure the OAuth server :

in out server we will use Authorization Server with the Password Grant

  1. open app\config\oauth2.php and find grant_types Array and add the following code inside it :
‘password’ => [
‘class’ => ‘League\OAuth2\Server\Grant\PasswordGrant’,
‘access_token_ttl’ => 604800,

// the code to run in order to verify the user’s identity
‘callback’ => function($username, $password){
$credentials = [
‘email’ => $username,
‘password’ => $password,

if (Auth::once($credentials)) {
return Auth::user()->id;
} else {
return false;

2. we need a new rout to generate the token after passing the username and password , in app\http\Route.php add the following Route

Route::post(‘oauth/access_token’, function() {
return Response::json(Authorizer::issueAccessToken());

3. Create Client

The client is the app that uses this oAuth server ( eg. website , android app , ..etc )

in the database find the oauth_client s Table , insert new record to it ,or you can use the following SQL code in phpMyAdmin:

INSERT INTO `oauth_clients` (`id`, `secret`, `name`, `created_at`, `updated_at`) VALUES
(‘f3d259ddd3ed8ff3843839b’, ‘4c7f6f8fa93d59c45502c0ae8c4a95b’, ‘Main website’, ‘2015–05–12 21:00:00’, ‘0000–00–00 00:00:00’);

the cliend_id : f3d259ddd3ed8ff3843839b

client_secret : 4c7f6f8fa93d59c45502c0ae8c4a95b

4. create new user ( test ) :

you need to create at least 1 user in users table to test this oAuth server :

i created new rout to create test user ,

Route::get(‘/register ‘,function(){$user = new App\User();
$user->name=”test user”;
$user->password = \Illuminate\Support\Facades\Hash::make(“password”);


in your browser go to http://localhost:8000/register ( blank page ) , check database table users you will find new record .

4. test the oAuth server :

to test our server we need REST client to pass the POST request , i recommend Chrome Plugin called PostMan( link) .

after installing postman on chrome you can test out server as follow :

testing data :

password = password
client_id = GXvOWazQ3lA6YSaFji
client_secret =GXvOWazQ3lA.6/YSaFji

5. Securing your API endpoints

to protect a resource you can use ‘before’ => ‘oauth’ in the route as follow:

Route::get(‘api’, [‘before’ => ‘oauth’, function() {
// return the protected resource
//echo “success authentication”;
$user_id=Authorizer::getResourceOwnerId(); // the token user_id
$user=\App\User::find($user_id);// get the user data from database
return Response::json($user);

to test the REST api route security , use postman plugin :

How to use token in Controller :

assume that we have a Post Controller and the user needs to send a token to get All his Posts .

step 1: Create the route and protect it with oauth , in App\Http\routes.php add the following lines:

Route::group(['prefix'=>'api','before' => 'oauth'], function()
Route::get('/posts', 'PostController@index');

i have created route group with prefix ( ‘prefix’=>’api’ ) and protected all the routes inside it with oauth (‘before’ => ‘oauth’).

NOTE : to access the token data, the route must be protected with oauth

step 2 : get the token owner and retrieve the user info , in PostController.php

use LucaDegasperi\OAuth2Server\Authorizer;
public function index(Authorizer $authorizer)

$user_id=$authorizer->getResourceOwnerId(); // the token user_id
$user=\App\User::find($user_id);// get the user data from database
     $posts= \App\Post::where('user_id','=',$user->id);

notes: we have injected (Authorizer $authorizer) to the index method to retrieve the owner for the token that the user sent in the request .
