Why google Calendar event not being created with stored access token and refresh token in php

问题

I have successfully integrated google OAuth 2.0 with Calendar permissions and I am storing access token and refresh token in the database, after that fetch both token. do not know what wrong I am doing the Calendar event not being created.

<?php 
include($_SERVER["DOCUMENT_ROOT"]."/config.php");
include($_SERVER["DOCUMENT_ROOT"]."/functions.php");
require  'vendor/autoload.php';

function getClient($useremail)
{
$client = new Google_Client();
$client->setApplicationName('Google Calendar API PHP Quickstart');
$client->setScopes(Google_Service_Calendar::CALENDAR);
$client->setAuthConfig('credentials.json');
$client->setAccessType('offline');
$client->setPrompt('select_account consent');

$currentTime=date('Y-m-d H:i:s');
$result = dbRowsSelect(array('refresh_token','access_token','expire_on'), "calendar_api_users", 
 "email = '".$useremail."' ","LIMIT 1");

if(count($result) > 0)
{
      $accessToken = $result[0]['access_token']; 
      $expire_on=$result[0]['expire_on'];
    if(strtotime($currentTime) < strtotime($expire_on))
      {
          $client->setAccessToken($accessToken);
      }
      else
      {
          $refreshToken = $result[0]['refresh_token'];
          // Refresh the token if possible, else fetch a new one.
          $client->fetchAccessTokenWithRefreshToken($refreshToken);

      }

    
}
return $client;
}


// Get the API client and construct the service object.
$email='xxxxx.xxxxxxx@gmail.com';
$client = getClient($email);
$service = new Google_Service_Calendar($client);
$calendarId = 'primary';
$optParams = array(
'maxResults' => 10,
'orderBy' => 'startTime',
'singleEvents' => true,
'timeMin' => date('c'),
 );
 $results = $service->events->listEvents($calendarId, $optParams);
 $events = $results->getItems();

 $event = new Google_Service_Calendar_Event(array(
'summary' => 'Google I/O 2015',
'location' => '800 Howard St., San Francisco, CA 94103',
'description' => 'A chance to hear more about Google\'s developer products.',
'start' => array(
'dateTime' => '2021-06-29T09:00:00-07:00',
'timeZone' => 'America/Los_Angeles',
),
'end' => array(
'dateTime' => '2021-06-29T17:00:00-07:00',
'timeZone' => 'America/Los_Angeles',
),
'recurrence' => array(
'RRULE:FREQ=DAILY;COUNT=1'
),
'reminders' => array(
'useDefault' => FALSE,
'overrides' => array(
  array('method' => 'email', 'minutes' => 24 * 60),
  array('method' => 'popup', 'minutes' => 10),
),
),
));

$calendarId = 'primary';
$event = $service->events->insert($calendarId, $event);
printf('Event created: %s\n', $event->htmlLink);

I have fetched access token and refresh token from database , I dont know where is error as its showing white screen no error.

Thanks in advance

When you get the result back from the database, set both the access token and the refresh token.

Then call isAccessTokenExpired if it is then call fetchAccessTokenWithRefreshToken

$client->refreshToken($result[0]['refresh_token']);
$client->setAccessToken($result[0]['access_token']);                    
            
// Refresh the access token if it's expired.
if ($client->isAccessTokenExpired()) {              
        $client->fetchAccessTokenWithRefreshToken($client->getRefreshToken());
        $client->setAccessToken($client->getAccessToken()); 
        // Note: add code here to save the new access token and refresh token.          
        }   

NOTE: IMO there is no reason for you to be storing the access token you can just store the refresh token set that and then request a new one everytime. Google wont mind. 😊
