AddSOAPRequestHeader

Description

Adds a SOAP header to a web service request before making the request.

Returns

Nothing.

Function syntax

AddSOAPRequestHeader(webservice, namespace, name, value [, mustunderstand])

History

ColdFusion MX 7: Added this function.

Parameters

Parameter	Description
`webservice`	A web service object as returned from the `cfobject` tag or the `CreateObject` function.
`namespace`	A string that is the namespace for the header.
`name`	A string that contains the name of the SOAP header in the request.
`value`	The value for the SOAP header; this can be a CFML XML value.
`mustunderstand`	Optional. True or False (default). Sets the SOAP mustunderstand value for this header.

Usage

Used within CFML code by a consumer of a web service before it calls the web service.

If you pass XML in the value parameter, ColdFusion ignores the namespace and name parameters. If you require a namespace, define it within the XML itself.

Example

There are two parts to this example. The first part is the web service CFC that this function (as well as the other ColdFusion SOAP functions) uses to demonstrate its interaction with a web service. To implement the web service for this function, see the example for AddSOAPResponseHeader.

Execute the following example as a client to see how the AddSOAPRequestHeader function operates.

<!--- Note that you might need to modify the URL in the CreateObject function 
    to match your server and the location of the headerservice.cfc file if it is 
    different than shown here. Likewise for the cfinvoke tag at the end. --->

<cfscript> 
    // Create the web service object. 
    ws = CreateObject("webservice", "http://localhost/soapheaders/headerservice.cfc?WSDL"); 
     
    // Set the username header as a string. 
    addSOAPRequestHeader(ws, "http://mynamespace/", "username", "tom", false); 
     
    // Set the password header as a CFML XML object. 
    doc = XmlNew(); 
    doc.password = XmlElemNew(doc, "http://mynamespace/", "password"); 
    doc.password.XmlText = "My Voice is my Password"; 
    doc.password.XmlAttributes["xsi:type"] = "xsd:string"; 
    addSOAPRequestHeader(ws, "ignoredNameSpace", "ignoredName", doc); 
 
    // Invoke the web service operation. 
    ret = ws.echo_me("argument"); 
     
    // Get the first header as an object (string) and as XML. 
    header = getSOAPResponseHeader(ws, "http://www.tomj.org/myns", "returnheader"); 
    XMLheader = getSOAPResponseHeader(ws, "http://www.tomj.org/myns", "returnheader", true);
