PHP SOAP webservice with NuSOAP gives no result if WSDL is configured - php

Question

I have a php soap webservice which I've created with using NuSOAP. I use the file 'test.php' to test it in the browser as 'http://www.mydowmain.com:8080/webservice/5/test.php'.
My code:
webservice.php
<?php
require_once('../lib/nusoap.php');
$server = new nusoap_server();
$server ->configureWSDL('server', 'urn:server'); //this line causes to 'no result'
$server ->wsdl->schemaTargetNamespace = 'urn:server'; //this line causes to 'no result'
$server -> register('getData');
function getData ()
{
$items = array(array("item1"),array("item2"));
return $items;
}
$HTTP_RAW_POST_DATA = isset($HTTP_RAW_POST_DATA) ? $HTTP_RAW_POST_DATA : '';
$server ->service($HTTP_RAW_POST_DATA);
?>
test.php
<?php
require_once('../lib/nusoap.php');
$client = new nusoap_client("http://www.mydowmain.com:8080/webservice/5/webservice.php?wsdl");
$result = $client ->call('getData');
print_r($result);
?>
Problem:
If I remove these lines
$server ->configureWSDL('server', 'urn:server');
$server ->wsdl->schemaTargetNamespace = 'urn:server';
it shows me the result fine. Otherwise I get a blank screen, get nothing. But I really need to configure the WSDL.
How can I edit the webservice.php so that the WSDL will be configured and I can get the result array on the test.php ?

Answer 1

To see error information about client you can add this :
$result = $client->call('getData');
$err = $client->getError();
if ($err) {
// Display the error
echo '<h2>Error</h2>' . $err;
// At this point, you know the call that follows will fail
exit();
}
else
{
echo $result;
}
After that, in the server.php, maybe the register needs more information about the return value.
$server->register('getData',
array("response"=>"xsd:string"),
'http://www.mydowmain.com:8080'
);

Try changing this:
$server ->wsdl->schemaTargetNamespace = 'urn:server';
Into this:
$server ->wsdl->schemaTargetNamespace = $namespace;
and define $namespace on top of it. That did the trick for me.
This is my code of my NuSOAP webservice:
require_once("lib/nusoap.php");
$namespace = "http://localhost:8080/Testservice/service.php?wsdl";
$server = new soap_server();
$server->configureWSDL("TestService");
$server->wsdl->schemaTargetNamespace = $namespace;
