hi
how can i use this for future https://testnet.binancefuture.com
I have two days to try, but I still can not
my code
`<?php
$KEY= 'xx';
$SECRET = 'xx';
// $BASE_URL = 'https://api.binance.com/'; // production
$BASE_URL = 'https://testnet.binancefuture.com/'; // testnet
function signature($query_string, $secret) {
return hash_hmac('sha256', $query_string, $secret);
}
function sendRequest($method, $path) {
global $KEY;
global $BASE_URL;
$url = "${BASE_URL}${path}";
echo "requested URL: ". PHP_EOL;
echo $url. PHP_EOL;
$ch = curl_init();
curl_setopt($ch, CURLOPT_HTTPHEADER, array('X-MBX-APIKEY:'.$KEY));
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, $method == "POST" ? true : false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$execResult = curl_exec($ch);
$response = curl_getinfo($ch);
// if you wish to print the response headers
// echo print_r($response);
curl_close ($ch);
return json_decode($execResult, true);
}
function signedRequest($method, $path, $parameters = []) {
global $SECRET;
$parameters['timestamp'] = round(microtime(true) * 1000);
$query = buildQuery($parameters);
$signature = signature($query, $SECRET);
return sendRequest($method, "${path}?${query}&signature=${signature}");
}
function buildQuery(array $params)
{
$query_array = array();
foreach ($params as $key => $value) {
if (is_array($value)) {
$query_array = array_merge($query_array, array_map(function ($v) use ($key) {
return urlencode($key) . '=' . urlencode($v);
}, $value));
} else {
$query_array[] = urlencode($key) . '=' . urlencode($value);
}
}
return implode('&', $query_array);
}
// get orderbook
// $response = sendRequest('GET', 'api/v3/depth?symbol=BNBUSDT&limit=5');
// echo json_encode($response);
// get account information, make sure API key and secret are set
// $response = signedRequest('GET', 'api/v3/account');
// echo json_encode($response);
// place order, make sure API key and secret are set, recommend to test on testnet.
$response = signedRequest('POST', 'fapi/v1/order', [
