(PHP ActiveX) SOAP WS-Security UsernameToken

Demonstrates how to add a UsernameToken with the WSS SOAP Message Security header.

Note: This example requires Chilkat v9.5.0.66 or later.

// This example requires the Chilkat Crypt API to have been previously unlocked.
// See Unlock Chilkat Crypt for sample code.

// An HTTP SOAP request is an HTTP request where the SOAP XML composes the body.
// This example demonstrates how to add a WS-Security header such as the following:
// 
// <wsse:UsernameToken xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd" wsu:Id="SecurityToken-6138db82-5a4c-4bf7-915f-af7a10d9ae96">
//   <wsse:Username>user</wsse:Username>
//   <wsse:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordDigest">CBb7a2itQDgxVkqYnFtggUxtuqk=</wsse:Password>
//   <wsse:Nonce>5ABcqPZWb6ImI2E6tob8MQ==</wsse:Nonce>
//   <wsu:Created>2010-06-08T07:26:50Z</wsu:Created>
// </wsse:UsernameToken>
// 

// First build some simple SOAP XML that has some header and body.
// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Xml')
$xml = new COM("Chilkat.Xml");
$xml->Tag = 'env:Envelope';
$xml->AddAttribute('xmlns:env','http://www.w3.org/2003/05/soap-envelope');
$xml->UpdateAttrAt('env:Header|n:alertcontrol',1,'xmlns:n','http://example.org/alertcontrol');
$xml->UpdateChildContent('env:Header|n:alertcontrol|n:priority','1');
$xml->UpdateChildContent('env:Header|n:alertcontrol|n:expires','2001-06-22T14:00:00-05:00');
$xml->UpdateAttrAt('env:Body|m:alert',1,'xmlns:m','http://example.org/alert');
$xml->UpdateChildContent('env:Body|m:alert|m:msg','Pick up Mary at school at 2pm');
print $xml->getXml() . "\n";
print '----' . "\n";

// The following SOAP XML is built:

// 	<env:Envelope xmlns:env="http://www.w3.org/2003/05/soap-envelope">
// 	 <env:Header>
// 	  <n:alertcontrol xmlns:n="http://example.org/alertcontrol">
// 	   <n:priority>1</n:priority>
// 	   <n:expires>2001-06-22T14:00:00-05:00</n:expires>
// 	  </n:alertcontrol>
// 	 </env:Header>
// 	 <env:Body>
// 	  <m:alert xmlns:m="http://example.org/alert">
// 	   <m:msg>Pick up Mary at school at 2pm</m:msg>
// 	  </m:alert>
// 	 </env:Body>
// 	</env:Envelope>
// 

// Now build the WSSE XML housing that we'll insert into the above SOAP XML at the end.

// 	<wsse:Security>
// 	  <wsse:UsernameToken xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd" wsu:Id="WSU_ID">
// 	    <wsse:Username>USERNAME</wsse:Username>
// 	    <wsse:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordDigest">PASSWORD_DIGEST</wsse:Password>
// 	    <wsse:Nonce>NONCE</wsse:Nonce>
// 	    <wsu:Created>CREATED</wsu:Created>
// 	  </wsse:UsernameToken>
// 	</wsse:Security>

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Xml')
$wsse = new COM("Chilkat.Xml");
$wsse->Tag = 'wsse:Security';
$wsse->UpdateAttrAt('wsse:UsernameToken',1,'xmlns:wsu','http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd');
$wsse->UpdateAttrAt('wsse:UsernameToken',1,'wsu:Id','WSU_ID');
$wsse->UpdateChildContent('wsse:UsernameToken|wsse:Username','USERNAME');
$wsse->UpdateAttrAt('wsse:UsernameToken|wsse:Password',1,'Type','http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordDigest');
$wsse->UpdateChildContent('wsse:UsernameToken|wsse:Password','PASSWORD_DIGEST');
$wsse->UpdateChildContent('wsse:UsernameToken|wsse:Nonce','NONCE');
$wsse->UpdateChildContent('wsse:UsernameToken|wsu:Created','CREATED');
print $wsse->getXml() . "\n";
print '----' . "\n";

// Insert the wsse:Security XML into the existing SOAP header:
// xHeader is a Chilkat.Xml
$xHeader = $xml->GetChildWithTag('env:Header');
$xHeader->AddChildTree($wsse);

// Now show the SOAP XML with the wsse:Security header added:
print $xml->getXml() . "\n";
print '----' . "\n";

// Now our XML looks like this:
// 	<env:Envelope xmlns:env="http://www.w3.org/2003/05/soap-envelope">
// 	    <env:Header>
// 	        <n:alertcontrol xmlns:n="http://example.org/alertcontrol">

// 	            <n:expires>2001-06-22T14:00:00-05:00</n:expires>
// 	        </n:alertcontrol>
// 	        <wsse:Security>
// 	            <wsse:UsernameToken xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd" wsu:Id="WSU_ID">
