JWTRefreshTokenBundle

The purpose of this bundle is manage refresh tokens with JWT (Json Web Tokens) in an easy way. This bundles uses LexikJWTAuthenticationBundle. At the moment only supports Doctrine ORM.

Prerequisites

This bundle requires Symfony 3.3+ or 4.0+.

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

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

Step 3: Configure your own routing to refresh token

Open your main routing configuration file (usually app/config/routing.yml) and copy the following four lines at the very beginning of it.

Step 4: Allow anonymous access to refresh token

Add next lines on security.yml file:

Step 5: Update your schema

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

USAGE

Config TTL

You can define Refresh Token TTL. Default value is 1 month. You can change this value adding this line to your config.yml file:

Config User identity field

You can change user identity field. Make sure that your model user has getter for this field. Default value is username. You can change this value by adding this line to your config.yml file:

Config TTL update

You can expand Refresh Token TTL on refresh. Default value is false. You can change this value adding this line to your config.yml file:

This will reset the token TTL each time you ask a refresh.

Config Firewall Name

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

Config UserProvider

You can define your own UserProvider. By default we use our custom UserProvider. You can change this value by adding this line to your config.yml file:

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

Use another entity for refresh tokens

You can define your own entity for refresh tokens. Create the entity class extending terehinis\JWTRefreshTokenBundle\Entity\RefreshToken in you own bundle:

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

Use another entity manager

You can tell JWTRefreshTokenBundle to use another entity manager than default one (doctrine.orm.entity_manager).

Just add this line to your config.yml file:

Generating Tokens

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

This refresh token is persisted in RefreshToken entity. 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 notice if refresh token is still valid. Your refresh token do not change but valid datetime will increase.

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:

Optional argument is datetime, it deletes all tokens smaller than this datetime:

We recommend to execute this command with a cronjob to remove invalid refresh tokens every certain time.

Revoke a token

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

Events

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

For example:
