Cómo detectar errores de cURL en PHP

Resuelto Harish Kurup asked hace 54 años • 5 respuestas

Estoy usando funciones PHPcurl para publicar datos en el servidor web desde mi máquina local. Mi código es el siguiente:

$c = curl_init();
curl_setopt($c, CURLOPT_URL, $url);
curl_setopt($c, CURLOPT_RETURNTRANSFER, true);
curl_setopt($c, CURLOPT_POST, true);
curl_setopt($c, CURLOPT_POSTFIELDS, $data);
$result = curl_exec($c);
if (curl_exec($c) === false) {
    echo "ok";
} else {
    echo "error";
}
curl_close($c);

Lamentablemente, no puedo detectar ningún error como 404, 500 o falla de red. Entonces, ¿cómo sabré que los datos no se publicaron ni se recuperaron del control remoto?

Puedes utilizar la curl_error()función para detectar si hubo algún error. Por ejemplo:

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $your_url);
curl_setopt($ch, CURLOPT_FAILONERROR, true); // Required for HTTP error codes to be reported via our call to curl_error($ch)
//...
curl_exec($ch);
if (curl_errno($ch)) {
    $error_msg = curl_error($ch);
}
curl_close($ch);

if (isset($error_msg)) {
    // TODO - Handle cURL error accordingly
}

Si CURLOPT_FAILONERRORes así false, los errores de http no provocarán curlerrores.

<?php
if (@$_GET['curl']=="yes") {
  header('HTTP/1.1 503 Service Temporarily Unavailable');
} else {
  $ch=curl_init($url = "http://".$_SERVER['SERVER_NAME'].$_SERVER['PHP_SELF']."?curl=yes");
  curl_setopt($ch, CURLOPT_FAILONERROR, true);
  $response=curl_exec($ch);
  $http_status = curl_getinfo($ch, CURLINFO_HTTP_CODE);
  $curl_errno= curl_errno($ch);
  if ($http_status==503)
    echo "HTTP Status == 503 <br/>";
  echo "Curl Errno returned $curl_errno <br/>";
}

puedes generar un error curl después de su ejecución

$url = 'http://example.com';

$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
if(curl_errno($ch)){
    echo 'Request Error:' . curl_error($ch);
}

y aquí está el código de error curl
