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.
    xml := chilkat.NewXml()
    xml.SetTag("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")
    fmt.Println(*xml.GetXml())
    fmt.Println("----")

    // 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:Nonce>NONCE</wsse:Nonce>
    // 	    <wsu:Created>CREATED</wsu:Created>
    // 	  </wsse:UsernameToken>
    // 	</wsse:Security>

    wsse := chilkat.NewXml()
    wsse.SetTag("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")

    fmt.Println(*wsse.GetXml())
    fmt.Println("----")

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

    // Now show the SOAP XML with the wsse:Security header added:
    fmt.Println(*xml.GetXml())
