How do I parse the header returned by cURL?
I am trying to communicate with an API using cURL. One of the methods requires me to pass the header value ININ-ICWS-CSRF-Token
(i.e. WAhtYWxoYXlla1dBY2NvUkRJWCQxZmUxZWFhZS0xZTE0LTQyNGYtYjdhZS0zNmZjN2MxYWJmODBYCjEwLjAuNC4xNjA=
) and Set-Cookie
(i.e. icws_904586002=bf7c7783-6766-4c4f-862b-48f25a9a3741
), so I need to extract them so that I can pass them later in my code.
Here's what I did to extract the header and body from the cURL / API response:
$respond = curl_exec($ch);
//throw cURL exception
if($respond === false){
$errorNo = curl_errno($ch);
$errorMessage = curl_error($ch);
throw new ApiException($errorMessage, $errorNo);
}
list($header, $body) = explode("\r\n\r\n", $respond, 2);
echo '<pre>';
print_r($header);
echo '</pre>';
This is the content of the value $header
:
HTTP/1.1 201 Created ININ-ICWS-CSRF-Token: WAhtYWxoYXlla1dBY2NvUkRJWCQxZmUxZWFhZS0xZTE0LTQyNGYtYjdhZS0zNmZjN2MxYWJmODBYCjEwLjAuNC4xNjA= ININ-ICWS-Session-ID: 904586002 Set-Cookie: icws_904586002=bf7c7783-6766-4c4f-862b-48f25a9a3741; Path=/icws/904586002 Location: /icws/904586002/connection Cache-Control: no-cache, no-store, must-revalidate Pragma: no-cache Expires: 0 Access-Control-Allow-Origin: * Access-Control-Allow-Credentials: true Content-Type: application/vnd.inin.icws+JSON; charset=utf-8 Date: Wed, 06 May 2015 17:13:44 GMT Server: HttpPluginHost Content-Length: 237
I would like to get results similar to this
the value of "ININ-ICWS-CSRF-Token" is "WAhtYWxoYXlla1dBY2NvUkRJWCQxZmUxZWFhZS0xZTE0LTQyNGYtYjdhZS0zNmZjN2MxYWJmODBYCjEwLjAuNC4xNjA=" the value of the "cookie" is "ININ-ICWS-CSRF-Token: WAhtYWxoYXlla1dBY2NvUkRJWCQxZmUxZWFhZS0xZTE0LTQyNGYtYjdhZS0zNmZjN2MxYWJmODBYCjEwLjAuNC4xNjA="

You can use the function http_parse_headers
to parse headers.
$hdr_array = http_parse_headers($header);
foreach ($hdr_array as $name => $value) {
echo "The value of '$name' is '$value'<br>";
}
If you haven't http_parse_headers
, you can use the code in Pedro Lobito's answer.
