JWTRefreshTokenBundle

The purpose of this bundle is manage refresh tokens with JWT (Json Web Tokens) in an easy way. This bundles uses LexikJWTAuthenticationBundle. Supports Doctrine ORM/ODM.

Prerequisites

This bundle requires PHP 7.1.3 or later and Symfony 3.4, 4.4, or 5.2+.

If you want to use this bundle with previous Symfony versions, please use 0.2.x releases.

Protip: Though the bundle doesn't force you to do so, it is highly recommended to use HTTPS.

Installation

Step 1: Download the Bundle

It's important you manually require either Doctrine's ORM or MongoDB ODM as well, these packages are not required automatically as you can choose between them. Failing to do so may trigger errors on installation

With Doctrine's ORM

$ composer require "doctrine/orm" "doctrine/doctrine-bundle" "gesdinet/jwt-refresh-token-bundle"

With Doctrine's MongoDB ODM

$ composer require "doctrine/mongodb-odm-bundle" "gesdinet/jwt-refresh-token-bundle"

or edit composer.json:

// ...
"gesdinet/jwt-refresh-token-bundle": "^1.0",
"doctrine/orm": "^2.4.8",
"doctrine/doctrine-bundle": "^1.4 || ^2.0",
"doctrine/mongodb-odm-bundle": "^3.4 || ^4.0"
// ...

Alternatively, a custom persistence layer can be used.

For that purpose:

• provide an implementation of Doctrine\Persistence\ObjectManager
• configure the bundle to use your object manager

Step 2: Enable the Bundle

Symfony 3 Version:
Register bundle into app/AppKernel.php:

<?php
// app/AppKernel.php

// ...
class AppKernel extends Kernel
{
    public function registerBundles()
    {
        $bundles = array(
            // ...
            new Gesdinet\JWTRefreshTokenBundle\GesdinetJWTRefreshTokenBundle(),
        );
    }

    // ...
}

Symfony 4 Version:
Register bundle into config/bundles.php (Flex should do this automatically):

return [
    //...
    Gesdinet\JWTRefreshTokenBundle\GesdinetJWTRefreshTokenBundle::class => ['all' => true],
];

Step 3 (Symfony 5.3+)

Configure the authenticator

Add the below lines to your security.yml file:

# app/config/security.yml or config/packages/security.yaml
security:
    enable_authenticator_manager: true

    firewalls:
        # put it before all your other firewall API entries
        api_token_refresh:
            pattern: ^/api/token/refresh
            stateless: true
            refresh_jwt: ~
    # ...

    access_control:
        # ...
        - { path: ^/api/token/refresh, roles: IS_AUTHENTICATED_ANONYMOUSLY }
        # ...
# ...

Step 3 (Symfony 5.2-)

Configure your own routing to refresh token

Open your main routing configuration file and copy the following four lines at the very beginning of it.

Symfony 3 Version:

# app/config/routing.yml
gesdinet_jwt_refresh_token:
    path:     /api/token/refresh
    defaults: { _controller: gesdinet.jwtrefreshtoken:refresh }
# ...

Symfony 4 Version:

# config/routes.yml
gesdinet_jwt_refresh_token:
    path:       /api/token/refresh
    controller: gesdinet.jwtrefreshtoken::refresh
# ...

Allow anonymous access to refresh token

Add next lines on security.yml file:

# app/config/security.yml or config/packages/security.yaml
    firewalls:
        # put it before all your other firewall API entries
        refresh:
            pattern:  ^/api/token/refresh
            stateless: true
            anonymous: true
    # ...

    access_control:
        # ...
        - { path: ^/api/token/refresh, roles: IS_AUTHENTICATED_ANONYMOUSLY }
        # ...
# ...

Step 4: Update your database schema

With the next command you will create a new table to handle your refresh tokens

php bin/console doctrine:schema:update --force

# or make and run a migration:
php bin/console make:migration
php bin/console doctrine:migrations:migrate

Usage

The below configurations can be put in the following files, depending on the Symfony version you are running:

Symfony 3 Version: app/config/config.yml
Symfony 4 Version: config/packages/gesdinet_jwt_refresh_token.yaml

Token TTL

You can define the refresh token TTL, this value is set in seconds and defaults to 1 month. You can change this value adding this line to your config:

gesdinet_jwt_refresh_token:
    ttl: 2592000

Update Token TTL

You can configure the bundle to refresh the TTL on a refresh token when it is used, by default this feature is disabled. You can change this value adding this line to your config:

gesdinet_jwt_refresh_token:
    ttl_update: true

Config Firewall Name

NOTE This setting is deprecated and is not used with the refresh_jwt authenticator

You can define Firewall name. Default value is api. You can change this value adding this line to your config:

gesdinet_jwt_refresh_token:
    firewall: api

Refresh Token Parameter Name

You can define the parameter name for the refresh token when it is read from the request, the default value is refresh_token. You can change this value adding this line to your config:

gesdinet_jwt_refresh_token:
    token_parameter_name: refreshToken

Set The User Provider

Symfony 5.3+

You can define a user provider to use for the authenticator its configuration:

# app/config/security.yml or config/packages/security.yaml
security:
    firewalls:
        api_token_refresh:
            pattern: ^/api/token/refresh
            stateless: true
            refresh_jwt:
                provider: user_provider_service_id

By default, when a user provider is not specified, then the user provider for the firewall is used instead.

Symfony 5.2-

NOTE This setting is deprecated and is not used with the refresh_jwt authenticator

You can define your own user provider, by default the gesdinet.jwtrefreshtoken.user_provider service is used. You can change this value by adding this line to your config:

gesdinet_jwt_refresh_token:
    user_provider: user_provider_service_id

For example, if you are using FOSUserBundle, user_provider must be set to fos_user.user_provider.username_email.

For Doctrine ORM UserProvider, user_provider must be set to security.user.provider.concrete.<your_user_provider_name_in_security_yaml>.

For example, in your app/config/security.yml or config/packages/security.yaml:

security:
    # ...
    providers:
        app_user_provider:
            # ...
    firewalls:
    # ...
# ...

then your user_provider_service_id is security.user.provider.concrete.app_user_provider.

Doctrine Manager Type

By default, this bundle sets the Doctrine Manager type to the ORM. If you want to use Doctrine's MongoDB ODM you have to change this value:

gesdinet_jwt_refresh_token:
    manager_type: mongodb

Set The User Checker

Symfony 5.3+

You can define a user checker to use for the firewall as part of the firewall configuration:

# app/config/security.yml or config/packages/security.yaml
security:
    firewalls:
        api_token_refresh:
            pattern: ^/api/token/refresh
            stateless: true
            user_checker: user_checker_service_id
            refresh_jwt: ~

Symfony 5.2-

NOTE This setting is deprecated and is not used with the refresh_jwt authenticator

You can define your own user checker, by default the security.user_checker service is used. You can change this value by adding this line to your config:

gesdinet_jwt_refresh_token:
    user_checker: user_checker_service_id

You will probably want to use a custom user provider along with your user checker to ensure that the checker receives the right type of user.

Single Use Tokens

You can configure the refresh token so it can only be consumed once. If set to true and the refresh token is consumed, a new refresh token will be provided.

To enable this behavior add this line to your config:

gesdinet_jwt_refresh_token:
    single_use: true

Use another entity for refresh tokens

You can define your own refresh token class on your project.

When using the Doctrine ORM, create a class extending Gesdinet\JWTRefreshTokenBundle\Entity\RefreshToken in your application:

<?php

namespace App\Entity;

use Doctrine\ORM\Mapping as ORM;
use Gesdinet\JWTRefreshTokenBundle\Entity\RefreshToken;

/**
 * This class extends Gesdinet\JWTRefreshTokenBundle\Entity\RefreshToken to have another table name.
 *
 * @ORM\Table("jwt_refresh_token")
 */
class JwtRefreshToken extends RefreshToken
{
}

When using the Doctrine MongoDB ODM, create a class extending Gesdinet\JWTRefreshTokenBundle\Document\RefreshToken in your application:

<?php

namespace App\Document;

use Doctrine\ODM\MongoDB\Mapping\Annotations as MongoDB;
use Gesdinet\JWTRefreshTokenBundle\Document\RefreshToken;

/**
 * This class extends Gesdinet\JWTRefreshTokenBundle\Document\RefreshToken to have another collection name.
 *
 * @MongoDB\Document(collection="jwt_refresh_token")
 */
class JwtRefreshToken extends RefreshToken
{
}

Then declare this class adding this line to your config.yml file:

gesdinet_jwt_refresh_token:
    refresh_token_class: App\Entity\JwtRefreshToken

Use another object manager

You can configure the bundle to use any object manager, just add this line to your config.yml file:

gesdinet_jwt_refresh_token:
    object_manager: my.specific.entity_manager.id

Disable automatic Doctrine mappings

NOTE This setting is deprecated and is no longer used

On some occasions, you may not want to have default Doctrine mappings of object manager enabled as you use neither ORM nor ODM but i.e. using DoctrineBundle for DBAL.

To disable dynamic Doctrine mapping add this line to your config:

gesdinet_jwt_refresh_token:
    doctrine_mappings: false

Generating Tokens

When you authenticate through /api/login_check with user/password credentials, LexikJWTAuthenticationBundle now returns a JWT Token and a Refresh Token data.

{
  "token": "eyxxxGciOiJSUzI1NiIsInR5cCI6IkpXUyJ9.eyJleHAiOjE0NDI0MDM3NTgsImVtYWlsIjoid2VibWFzdGVyQGdlc2RpbmV0LmNvbSIsImlhdCI6IjE0NDI0MDM3MzgifQ.bo5pre_v0moCXVOZOj-s85gVnBLzdSdsltPn3XrkmJaE8eaBo_zcU2pnjs4dUc9hhwNZK8PL6SmSNcQuTUj4OMK7sUDfXr62a05Ds-UgQP8B2Kpc-ZOmSts_vhgo6xJNCy8Oub9-pRA_78WzUUxt294w0IArrNlgQAGewk65RSMThOif9G6L7HzBM4ajFZ-kMDypz2zVQea1kry-m-XXKNDbERCSHnMeV3rANN48SX645_WEvwaHy0agChR4hTnThzLof2bShA7j7HmnSPpODxQszS5ZBHdMgTvYhlcWJmwYswCWCTPl3lsqVq_UOFI5_4arpSNlUwZsichqxXVAHX5idZqCWtoaqAbvNQe2IpinYajoXw-MlYKvcN2TLUF_8sy529olLUagf4FCpCO6JFxovv0E7ll9tUOVvx9LlannqV8976q5XCOoXszKonZSH7DhsBlW5Emjv7PailbARZ-hfl4YlamyY2QbnxAswYycfoxqJxbbIKYGA8dlebdvMyC7m9VATnasTuKeEKS3mP5iyDgWALBHNYXm1FM-12zHBdN3PbOgxmy_OBGvk05thYFEf2WVmyedtFHy4TGlI0-otUTAf2swQAXWhKtkLWzokWWF7l5iNzam1kkEgql5EOztXHDZpmdKVHWBVNvN3J5ivPjjJBm6sGusf-radcw",
  "refresh_token": "xxx00a7a9e970f9bbe076e05743e00648908c38366c551a8cdf524ba424fc3e520988f6320a54989bbe85931ffe1bfcc63e33fd8b45d58564039943bfbd8dxxx"
}

The refresh token is persisted as a RefreshTokenInterface object. After that, when your JWT valid token expires, if you want to get a new one you can proceed in two ways:

• Send you user credentials again to /api/login_check. This generates another JWT with another Refresh Token.
• Ask to renew valid JWT with our refresh token. Make a POST call to /api/token/refresh url with refresh token as payload. In this way, you can always get a valid JWT without asking for user credentials. But you must check if the refresh token is still valid. Your refresh token will not change but its TTL will increase.

Note that when a refresh token is consumed and the config option single_use is set to true the token will no longer be valid.

curl -X POST -d refresh_token="xxxx4b54b0076d2fcc5a51a6e60c0fb83b0bc90b47e2c886accb70850795fb311973c9d101fa0111f12eec739db063ec09d7dd79331e3148f5fc6e9cb362xxxx" 'http://xxxx/token/refresh'

This call returns a new valid JWT token renewing valid datetime of your refresh token.

Useful Commands

We give you two commands to manage tokens.

Revoke all invalid tokens

If you want to revoke all invalid (datetime expired) refresh tokens you can execute:

php bin/console gesdinet:jwt:clear

The command optionally accepts a date argument which will delete all tokens older than the given time. This can be any value that can be parsed by the DateTime class.

php bin/console gesdinet:jwt:clear 2015-08-08

We recommend executing this command as a cronjob to remove invalid refresh tokens on an interval.

Revoke a token

If you want to revoke a single token you can use this command:

php bin/console gesdinet:jwt:revoke TOKEN

Events

If you want to do something when token is refreshed you can listen for gesdinet.refresh_token event.

For example:

<?php

namespace App\EventListener;

use Gesdinet\JWTRefreshTokenBundle\Event\RefreshEvent;
use Psr\Log\LoggerInterface;
use Symfony\Component\EventDispatcher\EventSubscriberInterface;

class LogListener implements EventSubscriberInterface
{
    private $logger;

    public function __construct(LoggerInterface $logger)
    {
        $this->logger = $logger;
    }

    public function log(RefreshEvent $event)
    {
        $refreshToken = $event->getRefreshToken()->getRefreshToken();
        $user = $event->getToken()->getUser()->getUsername();
        
        $this->logger->debug(sprintf('User "%s" has refreshed it\'s JWT token with refresh token "%s".', $user, $refreshToken));
    }
    
    public static function getSubscribedEvents()
    {
        return array(
            'gesdinet.refresh_token' => 'log',
        );
    }
}

Token Extractor

The bundle provides a Gesdinet\JWTRefreshTokenBundle\Request\Extractor\ExtractorInterface to define classes which can read the refresh token from the request.

By default, the Gesdinet\JWTRefreshTokenBundle\Request\Extractor\ChainExtractor is used which allows checking multiple aspects of the request for a token. The first token found will be used.

You can create a custom extractor by adding a class to your application implementing the interface. For example, to add an extractor checking for a "X-Refresh-Token" header:

<?php

namespace App\Request\Extractor;

use Gesdinet\JWTRefreshTokenBundle\Request\Extractor\ExtractorInterface;
use Symfony\Component\HttpFoundation\Request;

final class HeaderExtractor implements ExtractorInterface
{
    public function getRefreshToken(Request $request, string $parameter): ?string
    {
        return $request->headers->get('X-Refresh-Token');
    }
}

This bundle handles automatically configuring ExtractorInterface objects and will automatically set the gesdinet_jwt_refresh_token.request_extractor container tag when your application uses autoconfiguration (autoconfigure: true in your services.yaml file). If autoconfiguration is not in use, you will need to manually configure the tag:

services:
    App\Request\Extractor\HeaderExtractor:
        tags:
            - { name: gesdinet_jwt_refresh_token.request_extractor }

Prioritizing Extractors

The gesdinet_jwt_refresh_token.request_extractor container tag supports prioritizing extractors, you can use this to set the preferred order for your extractors by adding a priority attribute. The higher the number, the sooner the extractor will be run.

services:
    App\Request\Extractor\HeaderExtractor:
        tags:
            - { name: gesdinet_jwt_refresh_token.request_extractor, priority: 25 }
