01. AufgabenstellungMusikStar Messenger• Realisierung in 10 Arbeitstagen• Design, Konzept, Programmierung• Integration in bestehende Applikation• Apache-Server, PHP, mySQL• Erhöhte Security & Besucherzahl

3



02. XMLSocketÜbersicht• XMLSocket seit Flash 5.0• RealTime DataExchange • Austausch von XML-Daten zw. Client & Server (Port)• Anfänglich viele Multiuser-OpenSource-Projekte• XMLSocket-Server in Java, Perl, Python, C++ etc.• Einfache Lösungen über PHP/Flash möglich

4



02. XMLSocket

5



02. XMLSocketAS-Methoden

connect(host, port)Baut Verbindung zu definiertem Host über genannten Port auf.

send(xmlObj)Sendet XML Object an den Server.

close()Beendet die Verbindung.

6



02. XMLSocketAS-EventHandler

onConnect() EventHandler bei Verbindungsaufbau. Gibt einen Boolean Wert zurück.

onData() EventHandler welcher onXML aufruft sobald neue Serverdaten da sind.

onXML()EventHandler bei "Ankunft" eines neuen XMLObject auf Seiten des Client.

onClose()EventHandler sobald der Server (aus was für Gründen auch immer) die Verbindung beendet.

02. XMLSocketBsp.: Flash 1/2

mySocket = new XMLSocket();

mySocket.onConnect = function(success) { if (success) { msgArea.text += "Server connection established!"; }else { msgArea.text += "Server connection failed!"; }};

mySocket.onClose = function() { msgArea.text += "Server connection lost";};

02. XMLSocketBsp.: Flash 2/2

mySocket.prototype.onData = function(msg) { msgArea.text += msg;}; mySocket.connect("dyn.domain.com", 9999); function msgGO() { if (inputMsg.text != "") { mySocket.send(inputMsg.text+"\n"); inputMsg.text = "";

}}

pushMsg.onRelease = function() {msgGO();}
