As3HttpClientLib is a HTTP client for AS3. It uses AS3Crypto TLSSocket support for implementing HTTPS. The lib can be used as a replacement for Flash’s URLRequest/URLStream API.

Some features:

• GET, HEAD, PUT, POST, DELETE
• multipart/form-data (PUT and POST)
• Post with application/x-www-form-urlencoded
• Reading chunked (Transfer-Encoding)

Sample

var client:HttpClient = new HttpClient();

client.listener.onStatus = function(event:HttpStatusEvent):void {
  // Notified of response (with headers but not content)
};

client.listener.onData = function(event:HttpDataEvent):void {
  // For string data
  var stringData:String = event.readUTFBytes();

  // For data
  var data:ByteArray = event.bytes;
};

client.listener.onComplete = function(event:HttpResponseEvent):void {
  // Notified when complete (after status and data)
};

client.listener.onError = function(event:ErrorEvent):void {
  var errorMessage:String = event.text;
};      

var uri:URI = new URI("http://www.google.com/search?q=rel-me");
client.get(uri);
