(转)利用AIR的ServerSocket类让 AIR 做socket服务器
自：http://luoke920.iteye.com/blog/1161549
新的air sdk 新增了 ServerSocket类, 利用它我们做一些简单的局域网应用,比如小型的办公聊天软件,以及一些基于socket的服务应用.这样as程序员可以自己搞定服务器端,不在去求于 java程序员.在一下大型应用还没有尝试过.期待有人能做一下大型应用的尝试.小型的办公应用足够能满足了.
首先看服务器端代码:
package { import flash.display.Sprite; import flash.events.Event; import flash.events.MouseEvent; import flash.events.ProgressEvent; import flash.events.ServerSocketConnectEvent; import flash.net.ServerSocket; import flash.net.Socket; import flash.text.TextField; import flash.text.TextFieldType; import flash.utils.ByteArray; public class Main extends Sprite { private var serverSocket:ServerSocket = new ServerSocket(); private var clientSocket:Socket; private var localIP:TextField; private var localPort:TextField; private var logField:TextField; private var message:TextField; private var _clients:Array = []; public function Main() { setupUI(); } //当客户端成功连接服务端 private function onConnect( event:ServerSocketConnectEvent):void { clientSocket = event.socket; clientSocket.addEventListener( ProgressEvent.SOCKET_DATA, onClientSocketData ); _clients.push(clientSocket); log( "Connection from " + clientSocket.remoteAddress + ":" + clientSocket.remotePort ); } //当有数据通信时 private function onClientSocketData( event:ProgressEvent ):void { var buffer:ByteArray = new ByteArray(); clientSocket.readBytes( buffer, 0, clientSocket.bytesAvailable ); log( "Received: " + buffer.toString() ); for (var i:int = 0; i < _clients.length; i++) { var item:Socket = _clients[i] as Socket; if (!item) continue; item.writeObject(buffer.toString()); item.flush(); } } //绑定服务器ip 开始监听端口 private function bind( event:Event ):void { if( serverSocket.bound ) { serverSocket.close(); serverSocket = new ServerSocket(); } serverSocket.bind( parseInt( localPort.text ), localIP.text ); serverSocket.addEventListener( ServerSocketConnectEvent.CONNECT, onConnect ); serverSocket.listen(); log( "Bound to: " + serverSocket.localAddress + ":" + serverSocket.localPort ); } //服务器端向所有客户端发送数据 private function send( event:Event ):void { try { if (_clients.length == 0) { log('没有连接'); return; } for (var i:int = 0; i < _clients.length; i++) { var item:Socket = _clients[i] as Socket; if (!item) continue; item.writeObject(message.text); item.flush(); } /*if( clientSocket != null && clientSocket.connected ) { clientSocket.writeUTFBytes( message.text ); clientSocket.flush(); log( "Sent message to " + clientSocket.remoteAddress + ":" + clientSocket.remotePort ); } else log("No socket connection.");*/ } catch ( error:Error ) { log( error.message ); } } // 输出日志 private function log( text:String ):void { logField.appendText( text + "\n" ); logField.scrollV = logField.maxScrollV; trace( text ); } //设置皮肤 private function setupUI():void { localIP = createTextField( 10, 10, "Local IP", "0.0.0.0"); localPort = createTextField( 10, 35, "Local port", "0" ); createTextButton( 170, 60, "Bind", bind ); message = createTextField( 10, 85, "Message", "Lucy can't drink milk." ); createTextButton( 170, 110, "Send", send ); logField = createTextField( 10, 135, "Log", "", false, 200 ) this.stage.nativeWindow.activate(); } private function createTextField( x:int, y:int, label:String, defaultValue:String = '', editable:Boolean = true, height:int = 20 ):TextField { var labelField:TextField = new TextField(); labelField.text = label; labelField.type = TextFieldType.DYNAMIC; labelField.width = 100; labelField.x = x; labelField.y = y; var input:TextField = new TextField(); input.text = defaultValue; input.type = TextFieldType.INPUT; input.border = editable; input.selectable = editable; input.width = 280; input.height = height; input.x = x + labelField.width; input.y = y; this.addChild( labelField ); this.addChild( input ); return input; } private function createTextButton( x:int, y:int, label:String, clickHandler:Function ):TextField { var button:TextField = new TextField(); button.htmlText = "<u><b>" + label + "</b></u>"; button.type = TextFieldType.DYNAMIC; button.selectable = false; button.width = 180; button.x = x; button.y = y; button.addEventListener( MouseEvent.CLICK, clickHandler ); this.addChild( button ); return button; } } } |
客户端代码,主要就是连接服务器端:
package { import flash.display.Sprite; import flash.events.Event; import flash.events.MouseEvent; import flash.events.ProgressEvent; import flash.events.ServerSocketConnectEvent; import flash.net.ServerSocket; import flash.net.Socket; import flash.text.TextField; import flash.text.TextFieldType; import flash.utils.ByteArray; public class MainClient extends Sprite { private var serverSocket:ServerSocket = new ServerSocket(); private var clientSocket:Socket; private var localIP:TextField; private var localPort:TextField; private var logField:TextField; private var message:TextField; private var _clients:Array = []; public function MainClient() { setupUI(); } private function onConnect( event:Event ):void { log('成功连接服务器!'); //trace('成功连接服务器!!!!'); //clientSocket.addEventListener( ProgressEvent.SOCKET_DATA, onClientSocketData ); log( "Connection from " + clientSocket.remoteAddress + ":" + clientSocket.remotePort ); } private function onClientSocketData( event:ProgressEvent ):void { var buffer:ByteArray = new ByteArray(); clientSocket.readBytes( buffer, 0, clientSocket.bytesAvailable ); log( "Received: " + buffer.toString() ); } public function bind(host:String = "localhost", port:Number = 9080):void { log('开始连接服务器!'); clientSocket = new Socket( localIP.text, parseInt( localPort.text )); clientSocket.addEventListener(Event.CONNECT, onConnect);//监听连接事件 } //向服务器发送数据 private function send( event:Event ):void { try { if( clientSocket != null && clientSocket.connected ) { clientSocket.writeUTFBytes( message.text ); clientSocket.flush(); //log( "Sent message to " + clientSocket.remoteAddress + ":" + clientSocket.remotePort ); } else log("No socket connection."); } catch ( error:Error ) { log( error.message ); } } private function log( text:String ):void { logField.appendText( text + "\n" ); logField.scrollV = logField.maxScrollV; trace( text ); } private function setupUI():void { localIP = createTextField( 10, 10, "Local IP", "0.0.0.0"); localIP.text = 'localhost'; localPort = createTextField( 10, 35, "Local port", "0" ); createTextButton( 170, 60, "Bind", bind ); message = createTextField( 10, 85, "Message", "Lucy can't drink milk." ); createTextButton( 170, 110, "Send", send ); logField = createTextField( 10, 135, "Log", "", false, 200 ) this.stage.nativeWindow.activate(); } private function createTextField( x:int, y:int, label:String, defaultValue:String = '', editable:Boolean = true, height:int = 20 ):TextField { var labelField:TextField = new TextField(); labelField.text = label; labelField.type = TextFieldType.DYNAMIC; labelField.width = 100; labelField.x = x; labelField.y = y; var input:TextField = new TextField(); input.text = defaultValue; input.type = TextFieldType.INPUT; input.border = editable; input.selectable = editable; input.width = 280; input.height = height; input.x = x + labelField.width; input.y = y; this.addChild( labelField ); this.addChild( input ); return input; } private function createTextButton( x:int, y:int, label:String, clickHandler:Function ):TextField { var button:TextField = new TextField(); button.htmlText = "<u><b>" + label + "</b></u>"; button.type = TextFieldType.DYNAMIC; button.selectable = false; button.width = 180; button.x = x; button.y = y; button.addEventListener( MouseEvent.CLICK, clickHandler ); this.addChild( button ); return button; } } } |
整体实现起来比较简单, 服务器端可以做分发. 如果做个聊天室也非常容易. 期待air的效率能再提高一些.
