This example shows us how to create an OAuth2 API with symfony and uses password grant type. I'll go step by step so that it becomes easy to follow. Since the API uses role_hierarchy to control controller access with @Security("has_roles('xxxxx')") in annotations, password grant type is the best/simplest option to use. See the reference links at the bottom of this post. We're going to use FOSOAuthServerBundle to secure our API.


Important


In example below, I expose client_id and client_secret in request URI to obtain access token for demonstration purposes. You should not do that in real world applications. Instead, you should encode both of them with base64_encode function and add it to request header as Authorization.


$clientId = 'i-am-client-id';
$clientSecret = 'i-am-client-secret';

$base64 = base64_encode($clientId.':'.$clientSecret);

$header = 'Basic '.$base64;

So you should use it like Authorization: Basic aS1hbS1jbGllbnQtaWQ6aS1hbS1jbGllbnQtc2VjcmV0 in your request. On top of that, you should remove username, password and grant_type from URI to send them as parameters encoded with application/x-www-form-urlencoded. Your final request should look like the one below.


curl -X POST
-H 'Authorization: Basic aS1hbS1jbGllbnQtaWQ6aS1hbS1jbGllbnQtc2VjcmV0'
-H 'content-type: application/x-www-form-urlencoded'
-d 'grant_type=password&username=inanzzz&password=123123'

Tests


As we can see below, API is now secured.


# Request

Create client credentials


Every client needs client_id, client_secret, username and password to generate access_token that is used in requests to consume API. Command below is used to generate client_id and client_secret.


namespace Application\ServerBundle\Command;

use FOS\OAuthServerBundle\Entity\Client;
use FOS\OAuthServerBundle\Entity\ClientManager;
use Symfony\Component\Console\Command\Command;
use Symfony\Component\Console\Input\InputInterface;
use Symfony\Component\Console\Input\InputOption;
use Symfony\Component\Console\Output\OutputInterface;

class CreateOauthClientCommand extends Command
{
const GRANT_TYPE = 'grant-type';

private $clientManager;

public function __construct(ClientManager $clientManager)
{
parent::__construct();

$this->clientManager = $clientManager;
}

protected function configure()
{
$this
->setName('create:oauth:client')
->setDescription('Creates a new OAuth client.')
->addOption(
self::GRANT_TYPE,
null,
InputOption::VALUE_REQUIRED | InputOption::VALUE_IS_ARRAY,
'Sets allowed grant type for client. Can be used multiple times.'
);
}

protected function execute(InputInterface $input, OutputInterface $output)
{
/** @var Client $client */
$client = $this->clientManager->createClient();
$client->setAllowedGrantTypes($input->getOption(self::GRANT_TYPE));

$this->clientManager->updateClient($client);

$this->echoCredentials($output, $client);
}

private function echoCredentials(OutputInterface $output, Client $client)
{
$output->writeln('OAuth client has been created...');
$output->writeln(sprintf('Public ID: %s', $client->getPublicId()));
$output->writeln(sprintf('Secret ID: %s', $client->getSecret()));
}
}

application_server.command.create_oauth_client:
class: Application\ServerBundle\Command\CreateOauthClientCommand
arguments:

Run command below and do not distribute credentials! This will add a new record in client table in database.

Create user information


Every client needs client_id, client_secret, username and password to generate access_token that is used in requests to consume API. Command below is used to generate username and password. Every user must have at least one role.

use Application\ServerBundle\Entity\User;

const PATTERN = '/^[a-zA-Z0-9]+$/';

private $validRoles = ['ROLE_USER', 'ROLE_ADMIN', 'ROLE_SUPER_ADMIN'];
private $entityManager;

{

$this->validateEmail($input->getOption(self::EMAIL));
$roles = $this->validateRoles($input->getOption(self::ROLE));

$user = new User();
$user->setUsername($input->getOption(self::USERNAME));
$user->setPassword($input->getOption(self::PASSWORD));
$user->setEmail($input->getOption(self::EMAIL));
$user->setRoles($roles);

$this->entityManager->persist($user);
$this->entityManager->flush();

$this->echoCredentials($input, $output);
}

private function validatePassword($password)
{
if (!preg_match(self::PATTERN, $password)) {
throw new BadCredentialsException(sprintf('Password must contain only numbers and letters.'));
}
}

private function validateEmail($email)
{
if (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
throw new BadCredentialsException(sprintf('Email must be a valid value.'));
}
}

private function validateRoles($roles)
{
$result = null;
foreach ($roles as $role) {
if (in_array($role, $this->validRoles)) {
$result[] = $role;
}
}

if (!$result) {
throw new InvalidOptionsException(sprintf('Role(s) must be a valid option.'));
}

return $result;
}

private function echoCredentials(InputInterface $input, OutputInterface $output)
{
$output->writeln('OAuth user has been created...');
$output->writeln(sprintf('Username: %s', $input->getOption(self::USERNAME)));
$output->writeln(sprintf('Password: %s', $input->getOption(self::PASSWORD)));
$output->writeln(sprintf('Roles: %s', json_encode($input->getOption(self::ROLE))));
}
}

services:
application_server.command.create_oauth_user:
class: Application\ServerBundle\Command\CreateOauthUserCommand
arguments:
- @doctrine.orm.entity_manager
tags:
- { name: console.command }

Run command below and do not distribute credentials! You actually don't need to set ROLE_USER because you already set ROLE_ADMIN which also covers ROLE_USER as we know. I've just set it as demonstration purposes. If you set ROLE_SUPER_USER to a new method in ServerController above, this user won't be able to access it via client application. This will add a new record in user table in database.


MacBook-Pro:oauth-server inanzzz$ php app/console create:oauth:user --username=inanzzz --password=123123 --email=inanzzz@inanzzz.com --role=ROLE_USER --role=ROLE_ADMIN
OAuth user has been created...
