Question

I am very new to the google cloud storage.

Sometimes, in a CMS, you need to create a directory first before able to upload file into it, so the mouse click can trigger an event to take the path as the base folder, then do a batch upload.

It's a file browser, they say.

This code below might help.

setApplicationName('Create a new folder');
$client->setClientId($clientId);
$scopes = array('https://www.googleapis.com/auth/devstorage.full_control');
$client->setScopes($scopes);
$service = new Google_Service_Storage($client);

if (isset($_SESSION['service_token'])) {
    $client->setAccessToken($_SESSION['service_token']);
}
if (!file_exists($privateKeyFile)) {
    die('missing the location of primary key file, given: ' . $privateKeyFile);
}
$key = file_get_contents($privateKeyFile);
$cred = new Google_Auth_AssertionCredentials(
        $clientEmailAddress
        , $scopes
        , $key
);
$client->setAssertionCredentials($cred);
if ($client->getAuth()->isAccessTokenExpired()) {
    $client->getAuth()->refreshTokenWithAssertion($cred);
}
$_SESSION['service_token'] = $client->getAccessToken();

/**
 * Creating Folder
 */
try {
    /* create empty file that acts as folder */
    $postBody = new Google_Service_Storage_StorageObject();
    $postBody->setName($newDirectory);
    $postBody->setSize(0);

    $created = $service->objects->insert($bucketName, $postBody, array(
        'name' => $newDirectory,
        'uploadType' => 'media',
        'projection' => 'full',
        'data' => '',
    ));
} catch (Exception $ex) {
    echo $ex->getMessage() . "\n
";
    print_r($ex->getTraceAsString());
    echo '
';
    die();
}

echo 'EOF';
