Deserialize WCF web service request in PHP - php

Question

I have a WCF web service with a Login operation taking a company name, user name and password as the three parameters. I am trying to create a PHP client app to communicate with this service. No matter what I pass to the Login operation I get the following error:
OperationFormatter encountered an invalid Message body. Expected to find node type 'Element' with name 'Login' and namespace ''. Found node type 'Element' with name 'parameters' and namespace ''
My client app:
<?php
try
{
$client = new SoapClient("https://somewhere.com/DataServiceRxPublic.svc?wsdl");
//$params = array(
// 'parameters' => array(
// 'Param' => array(
// array('Name' => 'loginCompany', 'Value' => 'XXX'),
// array('Name' => 'loginId', 'Value' => 'XXX'),
// array('Name' => 'loginPwd', 'Value' => 'XXX')
//)));
//$params = array(
// 'Login' => array(
// array('Name' => 'loginCompany', 'Value' => 'XXX'),
// array('Name' => 'loginId', 'Value' => 'XXX'),
// array('Name' => 'loginPwd', 'Value' => 'XXX')
//));
//$params = array(
// 'Login' => array(
// 'parameters' => array(
// array('Name' => 'loginCompany', 'Value' => 'XXX'),
// array('Name' => 'loginId', 'Value' => 'XXX'),
// array('Name' => 'loginPwd', 'Value' => 'XXX')
//)));
//$params = array(
// array('Name' => 'loginCompany', 'Value' => 'XXX'),
// array('Name' => 'loginId', 'Value' => 'XXX'),
// array('Name' => 'loginPwd', 'Value' => 'XXX')
//);
$params = array(
'loginCompany' => 'XXX',
'loginId' => 'XXX',
'loginPwd' => 'XXX'
);
$obj->loginCompany = 'XXX';
$obj->loginId = 'XXX';
$obj->loginPwd = 'XXX';
//$result = $client->Login($obj);
//$result = $client->Login($params);
}
catch (Exception $e)
{
print_r($e);
}
}
?>
$params being the different array permutations I've based off several different examples online.
Any help is appreciated.

Answer 1

The error message is telling you that there should have been something named "Login", but was named "parameters".
Go get SoapUI and with your WSDL follow the steps I described here to debug what you are actually sending. If you cannot compare what the service expects vs. what you are sending, this will be way too much trial-and-error.
If you need more external help, we'd need the WSDL resource - without it, nobody knows which request structure is expected.

Answer 2

Turns out I needed to extend the SOAPClient and override the __doRequest() method to replace the mismatched soap headers.

Answer 3

I managed to fix this error by modifying service namespace on server side.
[ServiceContract(Name="Service", Namespace = "https://sample.eu")]
Namespace was empty before.
