errores - php curl error

Cómo atrapar errores de curl en PHP

Question

Estoy usando las funciones curl de PHP 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);

Desafortunadamente no puedo detectar ningún error como 404, 500 o error de red. Entonces, ¿cómo voy a saber que los datos no fueron publicados o recuperados desde el control remoto?

Answer 1

Puede usar la función curl_error() 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_error($ch)) {
    $error_msg = curl_error($ch);
}
curl_close($ch);

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

Si CURLOPT_FAILONERROR es false , los errores http no desencadenarán errores curl .

<?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/>";
}

Answer 3

puedes generar un error de 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 están los códigos de error curl
