Bittrex API請求

Question

我試圖讓我與bittrex API電子錢包餘額，我不明白爲什麼由bittrex文檔提供的代碼無法正常工作：

$apikey = 'xxx'; 
$apisecret = 'xxx'; 
$nonce = time(); 
$uri = 'https://bittrex.com/api/v1.1/market/getopenorders?apikey=' . 
    $apikey . '&nonce=' . $nonce; 
$sign = hash_hmac('sha512', $uri, $apisecret); 
$ch = curl_init($uri); 
curl_setopt($ch, CURLOPT_HTTPHEADER, array('apisign:' . $sign)); 
$execResult = curl_exec($ch); 
$obj = json_decode($execResult); 

的curl_exec函數返回false，我不明白爲什麼。 感謝您的幫助！

嘗試添加更多的錯誤處理， smthing這樣

try { 
    $ch = curl_init(); 

    if (FALSE === $ch) 
     throw new Exception('failed to initialize'); 

    curl_setopt($ch, CURLOPT_URL, $uri); 
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 

    $execResult = curl_exec($ch); 

    if (FALSE === $execResult) 
     throw new Exception(curl_error($ch), curl_errno($ch)); 

} catch(Exception $e) { 

    trigger_error(sprintf(
     'Curl failed with error #%d: %s', 
     $e->getCode(), $e->getMessage()), 
     E_USER_ERROR); 

}
