How to include token in API rest

Here my example

1. I create Libraries Jsonwebtokens.php and put it on /application/libraries
2. Download https://github.com/firebase/php-jwt and put on /application/third_party/firebase-jwt
3. Here how I used it

Example:

PHP Code:

$this->load->library('jsonwebtokens');
$data = array('email' => $email);
$token = $this->jsonwebtokens->generate_jswt($data,'P30D'); 


Jsonwebtokens.php

PHP Code:

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

use \Firebase\JWT\JWT;

class Jsonwebtokens {

public function init() {
include APPPATH . 'third_party/firebase-jwt/JWT.php';
}

public function  generate_jswt($data = array(), $validity = 'P30D') {

$CI =& get_instance();

$this->init();
$jwt = '';

$date = new DateTime();
$timeStart = $date->getTimestamp();
$date->add(new DateInterval($validity));
$timeEnd = $date->getTimestamp();

/*
* iss – Issuer application.
* iat – timestamp of token issuing.
* nbf – Timestamp of when the token should start being considered valid.
* exp – Timestamp of when the token should cease to be valid.
* data – Array of data
*/

try {

$token = array(
"iss" => "MyApplicationName.com",
"aud" => "MyApplication Name",
"iat" => $timeStart,
"nbf" => $timeStart,
"exp" => $timeEnd,
"data" => $data);

$jwt = JWT::encode($token, "MyGeneratedKey","HS256");

} catch (Exception $ex) {
log_message('error',$ex->getMessage());
} finally {
return $jwt;
}


}

public function  validate_jswt($token) {

$this->init();

$jwt = null;

try {
$jwt = JWT::decode($token, "MyGeneratedKey",array("HS256"));
} catch (Exception $ex) {
log_message('error',$ex->getMessage());
} finally {
return $jwt;
}

}
}
