如何创建多个令牌来验证JWT相同请求Oauth2

Question

在具有API的网站上，我有5个帐户。我想做一个带来总价值的项目。

我想通过插入所有用户，发出API请求，在txt文件中获取和写入令牌来创建php类。但这不是最好的选择。

我正在寻找解决问题的最佳方法。

<?php
session_start();
require '../Meli/meli.php';
require '../configApp.php';
$meli = new Meli($appId, $secretKey);
if(isset($_GET['code']) || isset($_SESSION['access_token'])) {
    // If code exist and session is empty
    if(isset($_GET['code']) && !isset($_SESSION['access_token'])) {
        // //If the code was in get parameter we authorize
        try{
            $user = $meli->authorize($_GET["code"], $redirectURI);

            // Now we create the sessions with the authenticated user
            $_SESSION['access_token'] = $user['body']->access_token;
            $_SESSION['expires_in'] = time() + $user['body']->expires_in;
            $_SESSION['refresh_token'] = $user['body']->refresh_token;
        }catch(Exception $e){
            echo "Exception: ",  $e->getMessage(), "\n";
        }
    } else {
        // We can check if the access token in invalid checking the time
        if($_SESSION['expires_in'] < time()) {
            try {
                // Make the refresh process
                $refresh = $meli->refreshAccessToken();
                // Now we create the sessions with the new parameters
                $_SESSION['access_token'] = $refresh['body']->access_token;
                $_SESSION['expires_in'] = time() + $refresh['body']->expires_in;
                $_SESSION['refresh_token'] = $refresh['body']->refresh_token;
            } catch (Exception $e) {
                echo "Exception: ",  $e->getMessage(), "\n";
            }
        }
    }
    echo '<pre>';
        print_r($_SESSION);
    echo '</pre>';
} else {
    echo '<a href="' . $meli->getAuthUrl($redirectURI, Meli::$AUTH_URL[$siteId]) . '">Login using MercadoLibre oAuth 2.0</a>';
}
