Question

I am calling Python script from flex using HTTP service. How can I send back some values from python to flex app?

Thanks

Using HTTPService, many people will send back XML. Sometimes they’ll send back plain text. In your result handler, you should get the text returned from the service call as event.result.

Your result handler may look something like this, if you were to return XML:

public function onHTTPServiceResult(event:ResultEvent):void{
 var myResult : XML = event.result as XML
 // process XML in some manner
}

If you were to return plain text, it may look something like this:

public function onHTTPServiceResult(event:ResultEvent):void{
 var myResult : String = event.result as String
 // do something with the String value here
}

The only time I’ve used the latter approach is if the return value is really simple, like a Boolean value (true or false). The only time I use XML is when I have no control over what the remote service returns. If at all possible I try to use an AMF Gateway; which will automatically translate server side objects into ActionScript objects.

I can assume that you know how to create a service in Python to output XML or text data.
