错误SoapFault异常：[HTTP]禁止

Question

Help me please to solve this problem. I just want to test this example web service.

error:

3 add 4 = SoapFault exception: [HTTP] Forbidden in .....soap-client-2.php:14 Stack trace: #0 [internal function]: SoapClient->_doRequest('_call('getResult', Array) #2 ............/soap-client-2.php(14): SoapClient->getResult('add', 3, 4) #3 {main}

Client:

<?php
phpinfo();
    // Désactivation du cache WSDL
    ini_set("soap.wsdl_cache_enabled", "0");  

    $options = array("trace" => true);

  $client = new SoapClient("operation.wsdl", $options); 
  try { 
    $operation = "add";
    $integer1  = 3;
    $integer2  = 4;
    echo "$integer1 $operation $integer2 = ";
    echo $client->getResult($operation, $integer1, $integer2); 
    print "<pre>
"; 
      print "Request :
".htmlspecialchars($client->__getLastRequest()) ."
"; 
      print "Response:
".htmlspecialchars($client->__getLastResponse())."
"; 
      print "</pre>"; 
  } catch (SoapFault $exception) { 
    echo $exception;       
  } 
?>

server

<?php
/*
 * Fonction getResult sert à addition ou soustraire 2 entiers et retourne le résultat
 * @param $operation Type de l'opération (add/substract)
 * @param $integer1 Entier 1
 * @param $integer2 Entier 2
 * @return $result Résultat de l'opération
 */
function getResult($operation, $integer1, $integer2) {
    $result = 0;

    if (($operation != "add") && ($operation != "substract")) {
      throw new SoapFault("Server", "Veuillez utiliser une methode d'operation valable (add/substract).");
    } 
    if (!$integer1 || !$integer2) {
      throw new SoapFault("Server", "Veuillez indiquer 2 entiers.");
    } 
    if ($operation == "add") {
      $result = $integer1 + $integer2;
    }
    if ($operation == "substract") {
      $result = $integer1 -$integer2;
    }

    return $result; 
}  

// Désactivation du cache WSDL
ini_set("soap.wsdl_cache_enabled", "0");  


// Catch l'erreur si l'instanciation la classe SoapServer
// échoue, on retourne l'erreur
try { 
  $server = new SoapServer('operation.wsdl');
  // On ajoute la méthode "getResult" que le serveur va gérer
  $server->addFunction("getResult"); 
} catch (Exception $e) {
  echo 'erreur'.$e;
}

// Si l'appel provient d'une requête POST (Web Service)
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
  // On lance le serveur SOAP
  $server->handle();
}
else {
  echo '<strong>This SOAP server can handle following functions : </strong>';
  echo '<ul>';
  foreach($server->getFunctions() as $func) {
    echo '<li>' , $func , '</li>';
  }
  echo '</ul>';
}
