I would recommend going one step at a time. Learn how to create your own custom classes, learn OOP before stepping into the flickr API. However, if you really want to see how it is done, here's some sample actionscript that I found on the Tour de Flex app.
import com.adobe.webapis.flickr.events.FlickrResultEvent;
import com.adobe.webapis.flickr.*;
import mx.controls.Alert;
private var service:FlickrService;
private var queriedUser:String = "tourdeflex";
private var photosArray:Array;
private var flickrId:String;
private function init():void
{
/**
* You need to provide your own API keys here in order for the
* test to run.
*
* http://www.flickr.com/services/api/auth.howto.desktop.html
*/
var api_key:String = use your own API key here
service = new FlickrService( api_key );
service.secret = use your own secret here
service.addEventListener( FlickrResultEvent.AUTH_GET_FROB, onAuthGetFrob );
service.auth.getFrob();
}
private function onAuthGetFrob( event:FlickrResultEvent ):void {
if (event.success) {
var frob:String = String( event.data.frob );
onGet(null);
}
}
/**
* Note: This API requires the userid/pw to be logged in thru the flickr website to access
* many methods, but some public methods are available just by username, such as below.
*/
private function onGet(event:Event):void
{
if (userid.text!=null && userid.text.length >0) {
service.addEventListener( FlickrResultEvent.PEOPLE_FIND_BY_USERNAME,onPeopleFindByUsername);
service.people.findByUsername( userid.text );
}
else Alert.show("Please enter a flickr userid.");
}
private function onPeopleFindByUsername(event:FlickrResultEvent):void
{
var user:User = event.data.user;
if (user != null) {
flickrId = user.nsid;
service.addEventListener(FlickrResultEvent.PEOPLE_GET_PUBLIC_PHOTOS, genericResponseHandler);
service.people.getPublicPhotos(flickrId);
queriedUser=userid.text;
}
else {
Alert.show("Flickr userid " + userid.text + " not found.");
this.queriedUser = "";
this.resultPanel.title="";
this.dgData.dataProvider = new Array(); //clear the dg
}
}
/**
* Generically handle the response to a flickr method call - just output
* the information in the event to the screen.
*/
private function genericResponseHandler( event:FlickrResultEvent ):void
{
if ( event.success ) {
if (event.data.photos is PagedPhotoList)
{
var list:PagedPhotoList = PagedPhotoList(event.data.photos);
this.dgData.dataProvider = list.photos;
}
}
else {
// Encountered some kind of error on Flickr...
var e:FlickrError = FlickrError( event.data.error );
Alert.show("Flickr API error: " + e.errorMessage);
}
}
public function createUrl(server:String, photoId:String, secret:String):String
{
// Create the URL to the thumbnail based on the photo info
var url:String = "http://farm4.static.flickr.com/"+server+"/"+photoId+"_"+secret+"_t.jpg";
return url;
}
You'll still need to work out how to display the information, but at least all of the code for pulling the feed is here.
