I'm trying to write a web service that returns a complex datatype (like a struct but using a CFC instead), and one of the elements is an Array which contains complex datatypes. I need to make this portable so that a VB app can consume it (my prior solution when using Flash as the consumer was to just return structs..)
I was looking at the WSDL for the Google API, and it does exactly what I want to do. It returns a Complex Data Type named "GoogleSearchElement", which in turn contains a number of simple elements and a couple of complex data type elements. One of these sub-elements is named "GoogleSearchArray", a complex data type that is an array containing another complex datatype "ResultElement". That's as far as I really need to take this..
http://api.google.com/GoogleSearch.wsdl
So anyway... I want to mimic this functionality... but I can't figure out how.
Here is my ReturnObject CFC that describes the complex data type that I want to return... a couple of strings and an array.
<cfcomponent> <CFPROPERTY NAME="ERRORCODE" TYPE="STRING"> <CFPROPERTY NAME="ERRORMESSAGE" TYPE="STRING"> <CFPROPERTY NAME="Results" TYPE="array"> </cfcomponent>
Now, I want the "Results" array to be an array of "ResultElement" datatypes. so here is my ResultElement CFC...
<cfcomponent> <CFPROPERTY NAME="USERID" type="string"> <CFPROPERTY NAME="FULLNAME" type="string"> <CFPROPERTY NAME="TITLE" type="string"> <CFPROPERTY NAME="DEPT" type="string"> <CFPROPERTY NAME="PHONE" type="string"> <CFPROPERTY NAME="FAX" type="string"> <CFPROPERTY NAME="EMAIL" type="string"> </cfcomponent>
So next, I write a CFC that looks like this, called "directory.cfc"
<cfcomponent hint="Authorization Functions" output="no">
<cffunction name="getAllUsers" access="remote" returntype="ReturnObject"
displayname="getAllUsers" hint="getAllUsers">
<CFSET retVal =
CreateObject("component","components.authorization.ReturnObject")>
<CFSET retVal.ERRORCODE = "0">
<CFSET retVal.ERRORMESSAGE = "Success!">
<CFSET retVal.Results = ArrayNew(1)>
<CFSET retVal[1] =
CreateObject("component","components.authorization.ResultElement")>
<CFSET retVal[2] =
CreateObject("component","components.authorization.ResultElement")>
<CFSET retVal[1].USERID = "rick">
<CFSET retVal[1].FULLNAME = "Rick Root">
<CFSET retVal[1].TITLE = "Coder">
<CFSET retVal[2].USERID = "john">
<CFSET retVal[2].FULLNAME = "John Doe">
<CFSET retVal[2].TITLE = "Coder Assistant">
<CFRETURN retVal>
</cffunction></cfcomponent>
This works fine if I implement it via an HTTP call... as in:
http://www.ads.duke.edu/components/authorization/directory.cfc?method=getAllUsers
So finally, I write a CFM to invoke the web service via a SOAP call.
<cfinvoke webservice="http://www.ads.duke.edu/components/authorization/directory.cfc?WSDL";
method="getAllUsers" returnvariable="retVal"> <CFDUMP VAR="#retVal#">
And I call it: http://www.ads.duke.edu/components/authorization/directorytest.cfm
UGLY! HORROR! YUCK! NASTY ERROR!
