用HttpService實現簡單as3通訊

as3 code:  

HttpService.as

package { import flash.display.Sprite; import flash.events.Event; import flash.events.HTTPStatusEvent; import flash.events.IOErrorEvent; import flash.events.MouseEvent; import flash.events.ProgressEvent; import flash.events.SecurityErrorEvent; import flash.net.URLLoader; import flash.net.URLLoaderDataFormat; import flash.net.URLRequest; import flash.net.URLRequestMethod; import flash.net.URLVariables; import flash.net.navigateToURL; import flash.text.TextField; import flash.text.TextFieldType; public class HttpService extends Sprite { public function HttpService() { init(); reuqestServer(); } //服務端的http地址字符串 private var urlStr:String = "http://127.0.0.1:8080/webSange/TestHttpService.jsp"; private var _y:Number = 20; private function init():void { //畫一個圓 顏色爲黑色 var sprite:Sprite = new Sprite(); sprite.graphics.beginFill(0X000000); sprite.graphics.drawCircle(300,100,20); sprite.graphics.endFill(); sprite.addEventListener(MouseEvent.CLICK, clickHandler); sprite.buttonMode = true; this.addChild(sprite); } //點擊圓點將 go to jsp 發送到TestHttpService.jsp,然後顯示出來 private function clickHandler(e:Event):void { var name:String = "go to jsp"; var url:String = urlStr + "?name="+ name; navigateToURL(new URLRequest(url)); } //請求服務端 private function reuqestServer():void { //創建URLLoader對象 var urlLoader:URLLoader = new URLLoader(); //設置接收數據方式(文本、原始二進制數據、URL 編碼變量); urlLoader.dataFormat = URLLoaderDataFormat.VARIABLES; //設置傳遞參數 var urlVars:URLVariables = new URLVariables(); urlVars.name = "go 去服務端"; //建立Request訪問對象 var urlRequest:URLRequest = new URLRequest(urlStr); //設置參數 urlRequest.data = urlVars; //設置訪問模式(POST,GET) urlRequest.method = URLRequestMethod.POST; try { urlLoader.load(urlRequest); } catch(error:Error) { trace(error) } //加載完成 urlLoader.addEventListener(Event.COMPLETE, urlLoaderCompleteHandler); //開始訪問 urlLoader.addEventListener(Event.OPEN, urlLoaderOpenHandler); //加載進度 urlLoader.addEventListener(ProgressEvent.PROGRESS, urlLoaderProgressHandler); //跨域訪問安全策略 urlLoader.addEventListener(SecurityErrorEvent.SECURITY_ERROR, urlLoaderSecurityErrorHandler); //Http狀態事件 urlLoader.addEventListener(HTTPStatusEvent.HTTP_STATUS, urlLoaderHttpStatusHandler); //訪問出錯事件 urlLoader.addEventListener(IOErrorEvent.IO_ERROR, urlLoaderIoErrorHandler); } private function urlLoaderCompleteHandler(e:Event):void { var txt:TextField = new TextField(); txt.wordWrap = true; txt.width = 300; txt.type = TextFieldType.DYNAMIC; txt.text = "數據請求完成,返回數據爲：" + e.target.data.success; txt.y = 40; txt.multiline = true; this.addChild(txt); } private function urlLoaderOpenHandler(e:Event):void { var txt:TextField = new TextField(); txt.text = "連接已經打開"; txt.multiline = true; txt.y = 20; this.addChild(txt); } private function urlLoaderProgressHandler(e:ProgressEvent):void { var num:uint = (e.bytesLoaded / e.bytesTotal) * 100; var txt:TextField = new TextField(); txt.text = num + "%"; txt.y = 0; this.addChild(txt); } private function urlLoaderSecurityErrorHandler(e:SecurityErrorEvent):void { trace(e); } private function urlLoaderHttpStatusHandler(e:HTTPStatusEvent):void { trace(e); } private function urlLoaderIoErrorHandler(e:IOErrorEvent):void { trace(e); } } } 

 

java code:

TestHttpService.jsp

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%> <% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; %> <% request.setCharacterEncoding("utf-8"); String username=request.getParameter("name"); username += " 去客戶端"; out.clear(); out.print("success="+ username ); System.out.print(username); %>
