Apache – How to encrypt password and send through httpservice in flex

Just so everyone knows, this is how I resolved this issue:

I created a custom HTTPProxyAdapter on the server

public MyHTTPProxyAdapter extends flex.messaging.services.http.HTTPProxyAdapter {

public Object invoke(Message message) {
    // modify the message - if required
    process(message);
    return super.invoke(message);
}

private void process(Message message) {
        HTTPMessage http = (HTTPMessage)message;
        if(http != null) {
            String url = http.getUrl();
            ASObject o = (ASObject)http.getBody();
            if(o != null) {
                Set keys = o.keySet();
                Iterator it = keys.iterator();
                while(it.hasNext()) {
                    String key = (String)it.next();
                    String token = "[" + key +"]";
                    if(url.contains(token)) {
                        url = url.replace(token, o.get(key).toString());
                        o.remove(key);
                    }

                }
                http.setUrl(url);
            }
        }
    }
}

Then replaced the destination adapter to my adapter. I can now use the following URL in the config.xml and anything in square brackets will be replaced by the Query string:

<destination id="user-getbytoken">
        <properties>
            <url>http://localhost:8080/myapp/public/client/users/token/[id]</url>
        </properties>
</destination>

In this example, setting the destination to user-getbytoken and the parameters {id:123} will result in the url of http://localhost:8080/myapp/public/client/users/token/123

var timer:Timer = new Timer(5 * 60 * 1000); //time in milliseconds
timer.addEventListener(TimerEvent.TIMER, onTimer);
timer.start();
function onTimer(e:TimerEvent):void
{
  service.send();
}
