1C-Bitrix. How to get the user by login?

Question

1C-Bitrix

Hello.
How to get a user by login in Bitrix?
I am trying to use this method on a test page https://dev.1c-bitrix.ru/api_help/main/reference/c... + examples from it. But the answer is emptiness.
What needs to be connected first to receive data?
I would like to simply receive data without connecting the prologue, etc., since only data will be needed from this page, without an interface.
thanks in advance

if anything, the kernel is loaded in the prologue, so if you don’t have a prologue, it’s not that there will be a void, but there should be a fatal error with an excellent inscription that the class was not found,
in short, the prologue is required

require_once $_SERVER['DOCUMENT_ROOT'] . '/bitrix/modules/main/include/prolog_before.php';
