Custom code to convert

Question

Please convert your php code with a custom code.

function getCurl($fUrl,$fMethod,$fParam) {

$sUrl = $fUrl.(($fParam && strtolower($fMethod)=="get") ? "?$fParam": "");

$sMethod = (strtolower($fMethod)=="get") ? "0" : "1" ;

$sParam = (strtolower($fMethod)=="get") ? "" : $fParam ;

 

$ch = curl_init();

curl_setopt ($ch, CURLOPT_URL,"$sUrl"); //접속할 URL 주소

curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, FALSE); // 인증서 체크같은데 true 시 안되는 경우가 많다.

curl_setopt ($ch, CURLOPT_SSL_VERIFYHOST, FALSE);

// default 값이 true 이기때문에 이부분을 조심 (https 접속시에 필요)

curl_setopt ($ch, CURLOPT_SSLVERSION,3); // SSL 버젼 (https 접속시에 필요)

curl_setopt ($ch, CURLOPT_HEADER, 0); // 헤더 출력 여부

curl_setopt ($ch, CURLOPT_POST, $sMethod); // Post Get 접속 여부

curl_setopt ($ch, CURLOPT_POSTFIELDS, "$fParam"); // Post 값  Get 방식처럼적는다.

curl_setopt ($ch, CURLOPT_TIMEOUT, 30); // TimeOut 값

curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); // 결과값을 받을것인지

Hi,

Custom code is a feature where developer can write there own logic to achieve any particular requirement such as Server-Side IAP validation in your case. Writing a custom code has very easy steps which is explained here in detail. You can also get the guidelines for writing server side IAP validation from the following links:
