天使经纪人：智能 API 下单返回空响应

如何解决天使经纪人：智能 API 下单返回空响应

我是通过angelbroker smart api下单；但它返回空响应。它既不返回成功也不返回错误响应。 使用以下代码下订单：

$post_value_arr = array();
$post_value_arr = array(
    "variety" => "norMAL","Tradingsymbol" => "SBIN-EQ","symboltoken" => "3045","exchange" => "NSE","quantity" => "1","transactiontype" => "BUY","ordertype" => "MARKET","producttype" => "MIS","duration" => "DAY"
);
$post_value_json = json_encode($post_value_arr);

$ch = curl_init();
curl_setopt($ch,CURLOPT_URL,"https://apiconnect.angelbroking.com/rest/secure/angelbroking/order/v1/placeOrder");
curl_setopt($ch,CURLOPT_POST,1);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
//curl_setopt($ch,CURLOPT_HEADER,CURLOPT_POSTFIELDS,$post_value_json);
curl_setopt($ch,CURLOPT_HTTPHEADER,array('Authorization: Bearer ' . $auth_token,'Content-Type: application/json','Accept: application/json','X-UserType: USER','X-SourceID: WEB','X-ClientPublicIP: 172.29.24.173','X-ClientLocalIP: 172.29.24.173','X-MACAddress: e0:d5:5e:91:23:d4','X-PrivateKey: ' . $api_key));

// receive server response ...
$server_output = curl_exec($ch);
$server_output_arr = json_decode($server_output,true);

请检查代码并建议纠正问题。
