Hi

 I need to create a new web-service by using php. And I need to use SOAP RPC/encoded for implementing this. I also need to authenticate the soap request using soap header information.  Before doing main task that I have created a WSDL file, client and server files using php.

I have managed to send the soap request with header. But I am unaware of using the header information in the server side. That is I don't know how to check the header value is correct or not.

And I got error while I have setting "must-understand" to 1 or true. The error is "Header not understood".

I am  listing our WSDL, soap request, client and server here.

Please guide me to create a good web service with authentication using soap headers.

WSDL

<?xml version="1.0" encoding="ISO-8859-1"?> adds two string values and returns the result

SOAP Request

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

catalog1

</ns1:getCatalogEntry>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>

Client File

<?php ini_set("soap.wsdl_cache_enabled", "0"); $client = new SoapClient("catalog.wsdl",array('trace' => 1 )); $catalogId='catalog1'; $functions=$client->__getFunctions(); echo '

';
print_r($functions);


//	$soapHeader=new SoapHeader('http://soapinterop.org/echoheader/','username','hello world');
// $response = $client->getCatalogEntry('catalog1','catalogTest111', $soapHeader);
/*$bodyArr	= array('catalog1', 'catalogTest111');
$response 	= $client->__soapCall('getCatalogEntry', $bodyArr,NULL,$soapHeader,NULL);						   */
//		echo '--'.$client->__getLastRequest().'--';
$ns = 'http://namespace.example.com/';
//Body of the Soap Header.
$header = new SOAPHeader($ns, 'username', 'dipu'); 
$testArr	= array('catalogId'=>'catalog1','catalogId2'=>'catalogTest111');	
$response=$client->__soapCall("getCatalogEntry",$testArr,NULL, $header);
//Create Soap Header.       
echo $client->__getLastRequest();
//echo $client->__getLastRequestHeaders();

echo $response;
?>
Server File
<?php
function getCatalogEntry($catalogId,$catalogId2) { 
if($catalogId=='catalog1')

return "

Hum, I don’t think you’ll got lot of support here as it’s more wM centric.
May I suggest to send your request directly to a PHP forum ?

Anyway, I can’t help you as I have wrote only PHP client up to now But if you find an answer, can you please copy it here as I’m interested on the subject.

Thanks

Laurent

Google / Yahoo will be your friend because the only PHP forums I know are in French :o

Hi Dipu,

It will be very helpful if you can mention what changed you have done to make it work.

I am interested from WSDL, SOAP Request perspective.
