如何确定服务帐户路径的位置？

Question

I'm trying to authenticate in the code, per https://github.com/GoogleCloudPlatform/php-docs-samples/blob/master/auth/src/auth_cloud_explicit.php , but I don't know what to pass as the $serviceAccountPath. I copied the private .json file into the root of my app folder. What do I need to use here?

function auth_cloud_explicit($projectId, $serviceAccountPath)
{
    # Explicitly use service account credentials by specifying the private key
    # file.
    $config = [
        'keyFilePath' => $serviceAccountPath,
        'projectId' => $projectId,
    ];
    $storage = new StorageClient($config);
    # Make an authenticated API request (listing storage buckets)
    foreach ($storage->buckets() as $bucket) {
        printf('Bucket: %s' . PHP_EOL, $bucket->name());
    }
}

I think $serviceAccountPath should be contain the local path to your json configuration file (downloaded from Google console)
