How to Set a Break in HTTP in Flex 3

Question

I don't think my HTTP is being called properly and I am trying to set a break in the HTTP. What is the correct way to do this?

Answer 1

Your parse error is probably because the resultFormat property of HTTPService is not being set. What sort of data are you trying to retrieve? Look up the documentation and try to set resultFormat to an appropriate value (i.e. one of e4x, xml, text, etc.)

Define a resultHandler and faulthandler. Then set breakpoints in both these functions.

<HTTPService id="myservice" 
             ... 
             resultType="e4x" 
             result="resultHandler(event)" fault="faultHandler(event)"/>
<mx:Script> 
... 
    private function resultHandler(e:ResultEvent):void {
            trace(e.result); // set breakpoint here
    }


    private function resultHandler(e:FaultEvent):void {
            var faultstring:String = event.fault.faultString; // and here
            Alert.show(faultstring); 
    }

Answer 2

One additional thing you could try if you're not getting what you expect back in the resultHandler() would be to use an HTTP or network sniffer to see what is being transmitted.

I prefer Wireshark, but it's a little hard-core. Fiddler is also good for HTTP traffic.
