I am new in web services so apologize me if I am making some cardinal mistake here, hehe.
I have built SOAP service using PHP. Service is SOAP 1.2 compatible, and I have WSDL available. I have enabled sessions, so that I can track login status, etc.
I don't need some super security here (ie message-level security), all I need is transport security (HTTPS), since this service will be used infrequently, and performances are not so much of an issue.
I am having difficulties making it to work at all. C# throws some unclear exception ("Server returned an invalid SOAP Fault. Please see InnerException for more details.", which in turn says "Unbound prefix used in qualified name 'rpc:ProcedureNotPresent'."), but consuming service using PHP SOAP client behaves as expected (including session and all).
So far, I have following code. note: due to amount of real code, I am posting minimal code configuration
PHP SOAP server (using Zend Soap Server library), including class(es) exposed via service:
<?php
class Verification_LiteralDocumentProxy {
protected $instance;
public function __call($methodName, $args)
{
if ($this->instance === null)
{
$this->instance = new Verification();
}
$result = call_user_func_array(array($this->instance, $methodName), $args[0]);
return array($methodName.'Result' => $result);
}
}
class Verification {
private $guid = '';
private $hwid = '';
/**
* Initialize connection
*
* @param string GUID
* @param string HWID
* @return bool
*/
public function Initialize($guid, $hwid)
{
$this->guid = $guid;
$this->hwid = $hwid;
return true;
}
/**
* Closes session
*
* @return void
*/
public function Close()
{
// if session is working, $this->hwid and $this->guid
// should contain non-empty values
}
}
// start up session stuff
$sess = Session::instance();
require_once 'Zend/Soap/Server.php';
$server = new Zend_Soap_Server('https://www.somesite.com/api?wsdl');
$server->setClass('Verification_LiteralDocumentProxy');
$server->setPersistence(SOAP_PERSISTENCE_SESSION);
$server->handle();

And finally, WCF C# consumer code:
[ServiceContract(SessionMode = SessionMode.Required)]
public interface IVerification
{
[OperationContract(Action = "Initialize", IsInitiating = true)]
bool Initialize(string guid, string hwid);
[OperationContract(Action = "Close", IsInitiating = false, IsTerminating = true)]
void Close();
}
class Program
{
static void Main(string[] args)
{
WSHttpBinding whb = new WSHttpBinding(SecurityMode.Transport, true);
ChannelFactory<IVerification> cf = new ChannelFactory<IVerification>(
whb, "https://www.somesite.com/api");
IVerification client = cf.CreateChannel();
Console.WriteLine(client.Initialize("123451515", "15498518").ToString());
client.Close();
}
}
Any ideas? What am I doing wrong here?
Thanks!
