[flexcoders] Passing a varibable back to ActionScript via HTTPRequest

2008-12-18 Thread wkolcz 
I have a CF page that generates a Unique ID (UUID). I have an
HTTPRequest passes information to a CF page and I want it to generate
the number and then return it to ActionScript where it can use it as a
local variable. Any idea on how to do that? 
Does the HTTPRequest return a value? Does it have to be in XML?

Would I set the returned value in the
resulthandler? Here is what I have for a HTTPRequest:

private function startTrackIt(trackInfo:Object):void {
var service:HTTPService = new HTTPService();
service.url = tracker.cfm; //Dev
service.method = POST; 
service.addEventListener(ResultEvent.RESULT, timingSaved);
service.addEventListener(FaultEvent.FAULT, alertFault);
service.send(trackInfo);
}

What
would I need to do next to set a local variable in my AS? In a
RemoteObject, I usually set the a variable, typed ArrayCollection, in
the ResultHandler.

Sorry, this little idea is all new me and I am trying to figure it out.

OR Can Flash create a unique number like ColdFusion?

An HTTPService call will return a value if the server process writes
back a response.

 

You can set the resultFormat=text.  I have never done this since I
always wrap my returned data in a status node: returnstatus
status=success, stausdescription= MyData/returnstatus

 

This give me a consistent data structure to work with even if there is a
problem on the server.

 

Retrieve you data and process it however you want in the timingSaved()
handler.

Private function timingSaved(event.ResultEvent):void

var xmlResult:XML = event.result as XML;

var sStatus:String = xmlResult.attribute(status);

if (sStatus == success) {

_sUId == xmlResult.text(); //set your instance var value or whatever

}

else  {

  Alert.show(xmlResult.attribute(statusdescription)Server Error);

Just out of curiosity..  Why wouldn't you use a CFC with access=remote?
 Then you could use the Flex mx:RemoteObject and pretty much be good to
go.
http://www.adobe.com/devnet/flex/flex_cf.html

has the information you need to accomplish such a thing.
