(C# UWP/WinRT) 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.
Chilkat.Xml xml = new Chilkat.Xml();
xml.Tag = "env:Envelope";
xml.AddAttribute("xmlns:env","http://www.w3.org/2003/05/soap-envelope");
xml.UpdateAttrAt("env:Header|n:alertcontrol",true,"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",true,"xmlns:m","http://example.org/alert");
xml.UpdateChildContent("env:Body|m:alert|m:msg","Pick up Mary at school at 2pm");
Debug.WriteLine(xml.GetXml());
Debug.WriteLine("----");

// 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>

Chilkat.Xml wsse = new Chilkat.Xml();
wsse.Tag = "wsse:Security";
wsse.UpdateAttrAt("wsse:UsernameToken",true,"xmlns:wsu","http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd");

Debug.WriteLine("----");

// Insert the wsse:Security XML into the existing SOAP header:
Chilkat.Xml xHeader = xml.GetChildWithTag("env:Header");
xHeader.AddChildTree(wsse);

// Now show the SOAP XML with the wsse:Security header added:
Debug.WriteLine(xml.GetXml());
Debug.WriteLine("----");

// Now our XML looks like this:

// 	        <wsse:Security>
