오류 발생시 Curl 응답 헤더

Question

저는 PHP 클라이언트에서 API를 사용하고 있으며 Curl을 사용하여 요청합니다. 모두 잘 진행되지만 응답 HTTP 코드가 400 이상이면 응답에서 헤더를 가져올 수 없습니다.

내 API가 무엇이 잘못되었는지에 대한 자세한 정보가 포함 된 추가 헤더를 응답에 추가하기 때문에 모든 응답에서 헤더를 가져 오려면 필요합니다.

Curl의 응답에서 헤더를 항상 가져 오는 방법이 있다면?

$ch = curl_init(); 

    // Convert headers to curlopts

Answer 1

당신은 CURLOPT_HEADER 플래그를 설정해야합니다, 당신은 curl_getinfo를 사용하여 HTTP 상태 코드를 얻을 수 있습니다. 코드에서

<?php 
$ch = curl_init('http://yoururl/'); 
curl_setopt($ch, CURLOPT_HEADER, 1); 
$c = curl_exec($ch); 
echo curl_getinfo($ch, CURLINFO_HTTP_CODE);
