How do this work with Exchanges class? have you a little code snip for request "GET /sapi/v1/sub-account/list (HMAC SHA256)" for me? my code until now: `use Lin\Exchange\Exchanges; try { $tmp_arr = array(); if (isset($cfg_main_arr['msa_api']['binance']['key_ro'])) { $tmp_arr = $cfg_main_arr['msa_api']['binance']['key_ro']; } if (empty($tmp_arr)) { die('config.json error: binance api key "key_ro" not exists!'); } $ex_binance = new Exchanges('binance', $tmp_arr['APIKEY'], $tmp_arr['APISECRET']); $result = $ex_binance->getPlatform('spot') ->user() ->getAccount(); print_r($result); } catch (Exception $e) { // error mail senden!!! echo $e; }`
