传递请求到Java后台自己总结出了三种方式，也是我在项目当中用到的三种方式，今天把它写出来，一是为正在学习flex的新手一个好的指导，二是给自己是一个不忘的笔记： 一，通过httpService向java的servlet发送请求，然后返回一个结果： 第一步新一个httpService.mxml文件: <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"> <mx:Button x="277" y="162" label="点击" width="194" height="73" id="myButton" click="myFunction()"/>
<mx:HTTPService id="myHttpService" result="myResult(event)" fault="myFault(event)" method="POST" url="http://127.0.0.1:8080/httpService01/httpservcie.do"> <mx:request xmlns=""> <userName>name</userName> <userPwd>123</userPwd> </mx:request> </mx:HTTPService>
<mx:Script> <![CDATA[ import mx.rpc.events.FaultEvent; import mx.controls.Alert; import mx.rpc.events.ResultEvent; private function myFunction():void{ myHttpService.send(); } private function myResult(event:ResultEvent){ var msg = event.result.toString(); Alert.show(msg); } private function myFault(event:FaultEvent){ var msg = event.fault.toString(); Alert.show("错误:"+msg); } ]]> </mx:Script> </mx:Application> 第二步，写一个servlet: package com.lovo;
import java.io.IOException; import java.io.PrintWriter;
import javax.servlet.ServletException; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse;
public class HttpService extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
this.doPost(request, response); }
public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
request.setCharacterEncoding("UTF-8"); response.setContentType("text/html;charset=utf-8;"); PrintWriter out = response.getWriter();
String userName = request.getParameter("userName");
String userPwd = request.getParameter("userPwd"); out.print("你输入的姓名为："+userName+ "密码为:"+userPwd);
}
} 对于httpServlet就介绍完成了。上面代码是通过测试的
