Refreshed Google API does not get file list form drive. Google_Service_Exception (Err 400)

Question

I am trying to connect my web application with Google Drive, using the Google Drive API V2 and Google's PHP client library ("google/apiclient": "^2.0").

My application works fine for first hour. I can get files, uploads files, etc. but after 1 hour (when the access token expires and needs to be refreshed), subsequent gets/uploads result in a Google_Service_Exception (Err 400):

Your client has issued a malformed or illegal request.

I successfully obtain access & refresh tokens:

{
 "access_token":"**********",
 "expires_in":3600,
 "refresh_token":"1/********",
 "scope":"https://www.googleapis.com/auth/drive",
 "token_type":"Bearer",
 "created":1539085127
}

I have tried to refresh the token this way:

if ($client->isAccessTokenExpired()) {
    $client->fetchAccessTokenWithRefreshToken($client->getRefreshToken());
}

And this way:

if ($client->isAccessTokenExpired()) {
    $client->refreshToken($client->getRefreshToken());
}

How can I properly maintain the credentials I received for more than an hour?

A 400 error means you've not sent what they expect to receive — delboy1978uk, Oct 10 '18 at 10:23

Sounds like something is wrong with your client setup. Try this

function getOauth2Client() {
    try {

        $client = buildClient();

        // Set the refresh token on the client. 
        if (isset($_SESSION['refresh_token']) && $_SESSION['refresh_token']) {
            $client->refreshToken($_SESSION['refresh_token']);
        }

        // If the user has already authorized this app then get an access token
        // else redirect to ask the user to authorize access to Google Analytics.
        if (isset($_SESSION['access_token']) && $_SESSION['access_token']) {

            // Set the access token on the client.
            $client->setAccessToken($_SESSION['access_token']);                 

            // Refresh the access token if it's expired.
            if ($client->isAccessTokenExpired()) {              
                $client->fetchAccessTokenWithRefreshToken($client->getRefreshToken());
                $client->setAccessToken($client->getAccessToken()); 
                $_SESSION['access_token'] = $client->getAccessToken();              
            }           
            return $client; 
        } else {
            // We do not have access request access.
            header('Location: ' . filter_var( $client->getRedirectUri(), FILTER_SANITIZE_URL));
        }
    } catch (Exception $e) {
        print "An error occurred: " . $e->getMessage();
    }
}

Ripped from Oauth2Authentication.php might help as well oauth2callback.php

You can try to get file list by using curl.

if you want to get all file from google drive.

Use This Url in curl:

https://www.googleapis.com/drive/v2/files

Or, If you want to get file from specific folder.

Use This Url in curl:

https://www.googleapis.com/drive/v2/files?q='".$yourDriveFolderId."'+in+parents
