WSSE Security PHP SoapServer- Header not understood - php

Question

I have a client call with a WSSE Security Header:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Header><wsse:Security xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd"><wsse:UsernameToken wsu:Id="UsernameToken-7BCCD9337425FBA038149772606059420"><wsse:Username>USERNAME</wsse:Username><wsse:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText">PASSWORD</wsse:Password><wsse:Nonce EncodingType="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-soap-message-security-1.0#Base64Binary">NONCE</wsse:Nonce><wsu:Created>2017-06-17T19:01:00.594Z</wsu:Created></wsse:UsernameToken></wsse:Security></soapenv:Header>
<soapenv:Body>
<ns:FUNCTION/>
</soapenv:Body>
</soapenv:Envelope>
As SoapServer I have a simple one:
// the SOAP Server options
$options=array(
'trace' => true
, 'cache_wsdl' => 0
, 'soap_version' => SOAP_1_1
, 'encoding' => 'UTF-8'
);
$wsdl = 'http://localhost/index.php?wsdl';
$server = new \SoapServer($wsdl, $options);
$server->setClass('ServerClass');
$server->handle();
$response = ob_get_clean();
echo $response;
As soon the property MustUnderstand = 1, then I become from the server the exception: Header not understood.
How to understand the header?
How to make the WSSE validation on the SoapServer side?

Answer 1

The solution is very tricky! I don't know why is this handled by this way from the SoapServer, but here is the solution:
class ServerClass {
public function Security($data) {
// ... do nothing
}
public function myFunction(){
// here the body function implementation
}
}
We need to define a function in our class, which is handling the soap request with the name of the header tag, which is holding the soap:mustUnderstand property. The function doesn't need to be implemented in some way.
That's all!

Mutatos' question / answer got me on the right track. I was working outside of a class structure so what worked for me was the following:
function Security($data)
{
$username = $data->UsernameToken->Username;
$password = $data->UsernameToken->Password;
//check security credentials here
}
$server = new SoapServer("schema/wsdls/FCI_BookingPullService.wsdl", array('soap_version' => SOAP_1_2));
$server->addFunction("Security");
$server->handle();
Essentially a function with the same name as the SOAP header "<wsse:Security>" (ignore the namespace) is being defined, then telling the server to use that to process the header with the 'addFunction' method.
Not ideal from a scope point of view, if that's an issue, try the class approach.
