really simple Flickr API code for as3

example usage

var flickr:Flickr = new Flickr('YOUR_KEY_HERE');

flickr.call('flickr.people.findByUsername', { username: 'Steve Coast' }, function(event:Event):void {
    var rsp:XML = XML(event.target.data);
    var userId:String = rsp.user[0][email protected]();
    flickr.call('flickr.photos.search', { user_id: userId, has_geo: 1, extras: 'geo' }, function(event:Event):void {
        var rsp:XML = XML(event.target.data);
        for each (var photo:XML in rsp.photos.photo) {
            var lat:Number = parseFloat(photo.@latitude);
            var lon:Number = parseFloat(photo.@longitude);
            var title:String = [email protected]();
            var url:String = flickr.getURL(photo, '_t')
            // now do something with the picture, whatever you like
        }
    });
});

totally basic as3 Flickr lib

package
{
	import flash.events.ErrorEvent;
	import flash.events.Event;
	import flash.events.IOErrorEvent;
	import flash.events.SecurityErrorEvent;
	import flash.net.URLLoader;
	import flash.net.URLRequest;
	import flash.net.URLVariables;
	
	public class Flickr
	{
		public var base:String; 
		public var key:String;
		
		public function Flickr(key:String, base:String='http://api.flickr.com/services/rest/')
		{
			this.key = key;
			this.base = base;
		}
		
		public function call(method:String, params:Object, completeEventHandler:Function, errorEventHandler:Function=null):void
		{
			var loader:URLLoader = new URLLoader();
			var request:URLRequest = new URLRequest(base);
			var data:URLVariables = new URLVariables();
			data['method'] = method;
			data['api_key'] = key;
			for (var prop:String in params) {
				data[prop] = params[prop];
			}
			request.data = data;
			loader.addEventListener(Event.COMPLETE, completeEventHandler);
			if (errorEventHandler != null) {
				loader.addEventListener(IOErrorEvent.IO_ERROR, errorEventHandler);
				loader.addEventListener(SecurityErrorEvent.SECURITY_ERROR, errorEventHandler);
			}
			try { 
				loader.load(request);
			}
			catch (error:Error) {
				if (errorEventHandler != null) {
					errorEventHandler(new ErrorEvent(ErrorEvent.ERROR, false, false, error.message));
				}
			}
		}
		
		// size can be _m, _s, _t, or _b
		// no support for original here
		public function getURL(photo:XML, size:String=''):String
		{
			var farmId:String = [email protected]();
			var serverId:String = [email protected]();
			var id:String = [email protected]();
			var secret:String = [email protected]();
			return 'http://farm'+farmId+'.static.flickr.com/'+serverId+'/'+id+'_'+secret+size+'.jpg';			
		}
