Hi. I use nusoap client. But have a fault.
Array
(
[faultcode] => soap:server
[faultstring] => Server was unable to process request. ---> Object reference not set to an instance of an object.
[detail] =>
)

Help.please.

My nusoap client php code here.
<?php
$ns = "https://sonucservis.osym.gov.tr";

require_once('../lib/nusoap.php'); // nusoap-0.7.3

$proxyhost = isset($_POST['proxyhost']) ? $_POST['proxyhost'] : '';
$proxyport = isset($_POST['proxyport']) ? $_POST['proxyport'] : '';
$proxyusername = isset($_POST['proxyusername']) ? $_POST['proxyusername'] : '';
$proxypassword = isset($_POST['proxypassword']) ? $_POST['proxypassword'] : '';
$client = new nusoap_client('https://sonucservis.osym.gov.tr/service.asmx?wsdl', 'wsdl', $proxyhost, $proxyport, $proxyusername, $proxypassword);

$client->soap_defencoding = 'UTF-8';

if ($err) {
echo '<h2>Constructor error</h2><pre>' . $err . '</pre>';
}

$header = '<AuthenticationHeader xmlns="'.$ns.'"><KullaniciAdi>......</KullaniciAdi><Sifre>....</Sifre></AuthenticationHeader>';
$client->setHeaders($header);
$err = $client->getError();

$parameters['parameters']['SinavId'] = "....";
$parameters['parameters']['SinavYili'] = "....";
$parameters['parameters']['SinavDonemi'] = "....";
$parameters['parameters']['TcKimlikNo'] = ".....";

$result = $client->call('SonucGetir', $parameters, $ns, 'https://sonucservis.osym.gov.tr/SonucGetir', false, true);

// Check for a fault
if ($client->fault) {
echo '<h2>Fault</h2><pre>';
print_r($result);
echo '</pre>';
} else {
// Check for errors
$err = $client->getError();
if ($err) {
// Display the error
echo '<h2>Error</h2><pre>' . $err . '</pre>';
} else {
// Display the result
echo '<h2>Result</h2><pre>';
print_r($result);
echo '</pre>';
}
}
echo '<h2>Request</h2><pre>' . htmlspecialchars($client->request, ENT_QUOTES) . '</pre>';
echo '<h2>Response</h2><pre>' . htmlspecialchars($client->response, ENT_QUOTES) . '</pre>';
echo '<h2>Debug</h2><pre>' . htmlspecialchars($client->debug_str, ENT_QUOTES) . '</pre>';
?>

The error message means you are trying to use the -> operator on a non-object. This commonly occurs when an object is not set correctly and you end up with a reference to null. If I had to guess, I'd say that $client is not being set correctly here:

PHP Code:

$client = new nusoap_client('https://sonucservis.osym.gov.tr/service.asmx?wsdl', 'wsdl', $proxyhost, $proxyport, $proxyusername, $proxypassword); 


Make sure all the parameters to nusoap_client() are correct.

The error message means you are trying to use the -> operator on a non-object.

I don't think so, no..
The error string state

Server was unable to process request.

And beside, the message

Object reference not set to an instance of an object.

is the error .Net returns you when you try to do something on a uninitialized object.

My guess is that there is a problem on the web service itself, not in your code.
But maybe it's the parameters you send, that are in an erroneous format.

You should check their documentation.
Otherwise, what you did not tell us is when this error is triggered?

Is it when you call

PHP Code:

$client = new nusoap_client('https://sonucservis.osym.gov.tr/service.asmx?wsdl', 'wsdl', $proxyhost, $proxyport, $proxyusername, $proxypassword); 


, when you call

PHP Code:

$client->setHeaders($header); 


or when you call

PHP Code:

$result = $client->call('SonucGetir', $parameters, $ns, 'https://sonucservis.osym.gov.tr/SonucGetir', false, true); 


Hi.

I believe the way the parameters are correct.
I would send the authentication header information. Then I call the operation by sending string parameters.

request as follows:

</SOAP-ENV:Body>
</SOAP-ENV:Envelope>

and follows response :

perhaps related to the use of proxy within nusoap may be a problem?
Thank you for everything.

I am honestly not convinced...
This looks more like a problem on their side, in my opinion.

Did you tried to contact them ?

Dear senders,

I could not reach a solution nusoap.

problem was solved with cURL.

Thank you for your support.

good work.
