CodeIgniter-JWT-Sample using CodeIgniter 4

Simple Codeigniter 4, REST Server, JWT implementation.

Developers who want to use CodeIgniter 3:

Use following command to switch to CodeIgniter 3 branch

git checkout CI3

Update 1

As per multiple requests, I am adding logic for timeout.
Please check application\controllers\Authtimeout.php for more details.

Note: I did not add logic for expired token replacement after timeout.

Update 2

I upgraded CodeIgniter to v4. The old code (CodeIgniter 3) is available on branch CI3.

Setup using this repo

Set up project on php server (XAMPP/Linux).

• .htaccess file at project root

  This project contains .htaccess file for windows machine. Please update this file as per your requirements.
  [Sample htaccess code (Win/Linux)] (http://stackoverflow.com/questions/28525870/removing-index-php-from-url-in-codeigniter-on-mandriva)

• encryption_key in application\config\config.php
  [Encryption key generator] (http://jeffreybarke.net/tools/codeigniter-encryption-key-generator/)

$config['encryption_key'] = '';

• jwt_key in application\config\jwt.php

$config['jwt_key']	= '';

• For Timeout token_timeout in application\config\jwt.php

$config['token_timeout']	= ;

Setup for existing projects

You will need following files:

/application/config/jwt.php <= Add jwt_key here /application/helpers/authorization_helper.php /application/helpers/jwt_helper.php

In /application/config/autoload.php add

$autoload['helper'] = array('url', 'form', 'jwt', "authorization");
$autoload['config'] = array('jwt');

That's it. You are ready. Add your logic to generate token, eg.

$tokenData = array();
$tokenData['id'] = 1; //TODO: Replace with data for token
$output['token'] = AUTHORIZATION::generateToken($tokenData);

Please reply, if you need additional details. Happy coding!
