Welcome to the RingCentral Community

I'm having an issue building out my first RingCentral app. Using PHP 7 with the RingCentral PHP SDK fetched via Composer.

The idea here is the app will need to be authorized once upon startup, and will stay logged in as long as the app is running, allowing any user who queries the app to achieve a result from RingCentral, parsed in a manner acceptable for my org.

When the app goes through the oauth2 login flow, upon success it will store the access token to a cache (Redis):

if (isset($_REQUEST['oauth2callback'])){
 if (!isset($_GET['code'])) {
 return;
 }
 $qs = $platform->parseAuthRedirectUrl($_SERVER['QUERY_STRING']);
 $qs["redirectUri"] = $RINGCENTRAL_REDIRECT_URL;

 $platform->login($qs);
 $_SESSION['sessionAccessToken'] = $platform->auth()->data();
 
 $redis->set("accessToken", serialize($_SESSION['sessionAccessToken']));

On every subsequent page load that requires the app to be authenticated with RingCentral, we check if the token exists, and set it on the platform object if appropriate. Else, we'll redirect to the login flow.

$rcsdk = new SDK($RINGCENTRAL_CLIENT_ID, $RINGCENTRAL_CLIENT_SECRET, $RINGCENTRAL_SERVER_URL);
$platform = $rcsdk->platform();

if (! $redis->get("accessToken")) { 
 header("Location: " . $host);
}
else {
 session_start();
 $_SESSION['sessionAccessToken'] = $redis->get('accessToken');
 $platform->auth()->setData( unserialize( $_SESSION['sessionAccessToken'] ) );
}

Based on the README for the php SDK, the platform object is capable of refreshing the token itself in the event that the access token expires.


The app has a component where it runs a cron job periodically to seed it's database with fresh data from the RC API:

<?php

// Log in to the API
require(__DIR__ . '/vendor/autoload.php');
require_once("./config/configs.php");
require_once("./database/redis.php");

use RingCentral\SDK\Http\HttpException;
use RingCentral\SDK\Http\ApiResponse;
use RingCentral\SDK\SDK;

$rcsdk = new SDK($RINGCENTRAL_CLIENT_ID, $RINGCENTRAL_CLIENT_SECRET, $RINGCENTRAL_SERVER_URL);
$platform = $rcsdk->platform();

if (! $redis->get("accessToken")) { 
 die("Cron is exiting because the app is not logged in");
}

// Get the call records
$platform->auth()->setData( unserialize( $redis->get("accessToken") ) );
try { 
 $apiResponse = $rcsdk->platform()->get('/restapi/v1.0/account/~/active-calls', array( "Direction" => "Inbound", "view" => "Detailed")) ;
}
catch (\RingCentral\SDK\Http\ApiException $e) {
 // Getting error messages using PHP native interface
 print 'RC API Error: ' . $e->getMessage() . PHP_EOL;
 die();
}
// Store to DB
$redis->set("callLog", serialize($apiResponse->json()->records));

echo "Refreshed the call data!";
?>

After about an hour of leaving the application running, the cron starts dieing out on:

RC API Error: Token not found

I was able to dump the request and response objects when I get a Token not found error:

So, clearly, the token refreshing is either
a) not happening
b) happening in a context that doesn't push the token back up to my client

Can I be provided with some sample code to manually refresh the token?
Or guidance on storing the refreshed token so that the app will function?
Seeing as I already run cron jobs to seed data, adding another (check if token is refreshed ? do token refresh) block of code will be trivial at this point.

Many thanks!
