JWT (JSON Web Token) for Craft CMS assists in issuing and claiming tokens. The intent is to issue a token which, at a later time, can be claimed and used to perform various actions.
The life of a JWT is defined upon creation and

Use Cases

  • Protected downloads
  • Protected pages/content
  • Authorization to API
  • Tracking actions (by user)
  • Sharing downloads/pages to guests

Requirements

This plugin requires Craft CMS 3.0 or later.

Installation

Simply run the following command from your project root:

composer require flipboxfactory/craft-jwt

Once the plugin is included in your project, navigate to the Control Panel, go to Settings → Plugins and click the “Install” button for the JWT Plugin.

Templating

The craft.jwt template variable provides access to the entire JWT plugin. To access the services, you may use:

Identity Service:

{% set token = craft.jwt.identity.issue(currentUser) %} {# To generate a token (store the identity) #}
{% set claim = craft.jwt.identity.claim(token|trim) %} {# To claim a token (retrieve the identity) #}

Route Service:

{% set token = craft.jwt.route.issue('action/path') %} {# To generate a token (store the action path) #}
{% set claim = craft.jwt.route.claim(token|trim) %} {# To claim a token (retrieve the action path) #}

Examples

Common usages of this plugin are as follows:

Self-Consumable API (Hybrid API - calling your own API)

Making calls to your own API is a great candidate for JWT Identity tokens. The flow works something like this:

  1. Set a JavaScript variable: let jwt = '{{ craft.jwt.identity.issue(currentUser) }}'
  2. Using Axois (or other HTTP client library), make a call to your own API using the JWT token created in step 1.
  3. Apply the Authentication filter to your API controller(s).
/**
 * @inheritdoc
 */
public function behaviors()
{
    return \craft\helpers\ArrayHelper::merge(
        parent::behaviors(),
        [
            'authenticator' => [
                'authMethods' => [
                    \flipbox\craft\jwt\filters\JwtHttpBearerAuth::class
                ]
            ]
        ]
    );
}

A full example of the Authentication filter implementation can be found in our RESTful API for Craft CMS

Protected Downloads (or page access)

Perhaps a user needs to access a protected page or file download. To circumvent exposing the url publicly, issue a JWT Route token.

Render template:
{% set token  = craft.jwt.route.issue(['templates/render', {'template': '_protected/template'}], currentUser)
{# the link will automatically render the template #}
<a href="{{ actionUrl("jwt/route", {jwt: token|trim}) }}">View Protected Page</a>
File Download
{% set asset = craft.assets.one() %}
{% set token  = craft.jwt.route.issue(['assets/thumb', {'uid': asset.uid, width: 100, height: 100}], currentUser) %}
<a href="{{ actionUrl("jwt/route", {jwt: token|trim}) }}">Download Protected File</a>

Note: It's important to note that in the File Download example, we're also passing the currentUser param when generating the token. As a result, when the action is processed we're assuming the identity of the user who issued the token prior to performing the action. This means a user doesn't have to be logged in to Craft.

Caution

JWTs created by this plugin are technically JWS (JSON Web Signature) tokens. The contents of a token can be easily decoded and viewed using tools such as jwt.io. It is important NOT to store sensitive data in a token. The Craft 'security key' is used to sign each token; ensuring the contents have not been tampered with.

A token is valid for
