周一上班的第一天，老大说要我熟悉一下网络协议和硬件交互（以前常用Socket所以我认为是要从UDP和串口开始着手），好吧，你是老大你说的算，然后我就开始学习UDP。
先贴接收的代码：
public class Main extends MovieClip { private var txt:TextField=new TextField(); private var datagramSocket:DatagramSocket=new DatagramSocket(); public function Main() { // constructor code addChild(txt); txt.text="aaaaaaaa"; bindFunc(); } private function bindFunc():void{ if(datagramSocket.bound){ datagramSocket.close(); datagramSocket=new DatagramSocket(); } datagramSocket.bind(8080,"192.168.1.130"); datagramSocket.addEventListener(DatagramSocketDataEvent.DATA,onDataEvent); datagramSocket.receive(); } private function onDataEvent(e:DatagramSocketDataEvent):void{ trace("ip"+e.srcAddress); trace("port"+e.srcPort); //var str=e.data.readUTFBytes(e.data.bytesAvailable); var str=e.data.readUTFBytes(e.data.bytesAvailable); trace(e.data.readUTFBytes(e.data.bytesAvailable)); //trace(e.data.readUTFBytes(e.data.objectEncoding)); trace("msg"+str); txt.text=str; } }
然后贴发送的代码：
public class Main extends MovieClip { private var udpSocket:DatagramSocket=new DatagramSocket(); private var bytes:ByteArray=new ByteArray(); private var txt:TextField=new TextField(); public function Main() { // constructor code //bytes.writeUTFBytes("1234"); //bytes.writeUTF("hello"); bytes.writeUTFBytes("hello"); udpSocket.send(bytes,0,0,"192.168.1.130",8080); bytes.clear(); stage.addEventListener(MouseEvent.CLICK,onC); addChild(txt); txt.type=TextFieldType.INPUT; txt.border=true; } private function onC(e:MouseEvent):void{ //bytes.writeUTF(txt.text); bytes.writeUTFBytes(txt.text); udpSocket.send(bytes,0,0,"192.168.1.130",7777); bytes.clear(); } }
其实后来我琢磨了一下，UDP应该是接收的时候要绑定自己的IP和端口，发送的时候要写对方的IP和端口。
