Flex beta2+XFire开发实例 （三）

最后一章

三、编写调用实例

1、设计界面

我是做得比较简单，有一个TextArea用来显示调用结果输出，一个Button用来调用服务的login方法。

2、代码编写

Webs1.mxml

<?xml version="1.0" encoding="utf-8"?>

<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" creationComplete="init(event);">

    <mx:Button x="207" y="192" label="getUserInfo" click="getUserInfo(event);"/>

    <mx:TextArea x="80" y="57" width="223" height="127" id="out"/>

    <mx:Script>

       <![CDATA[

           import symis.business.service.UserManagerService;

           import symis.business.service.User;

           import mx.rpc.events.ResultEvent;

           import mx.rpc.AsyncToken;

           privatevar userManagerService:UserManagerService;

          

           privatefunction init(e:Event):void{

              userManagerService = new UserManagerService();

           }

           privatefunction getUserInfo(e:Event):void{

              var result:AsyncToken =null;

              if(userManagerService!=null)   

                  result =userManagerService.login(100,"hello");

              if(result!=null)

               result.addEventListener("result",function(e:ResultEvent):void{

                  var user:User = e.result as User;

                  out.text = "User Name:="+user.name+""n";

                  out.text +="age :="+user.age;

              });

           }

       ]]>

    </mx:Script>

</mx:Application>

3、运行客户端

a)       初始化webservice privatefunction init(e:Event):void{               userManagerService = new UserManagerService();            }

b)       调用webservice方法 privatefunction getUserInfo(e:Event):void{               var result:AsyncToken =null;               if(userManagerService!=null)                      result =userManagerService.login(100,"hello");               if(result!=null)                result.addEventListener("result",function(e:ResultEvent):void{                   var user:User = e.result as User;                   out.text = "User Name:="+user.name+""n";                   out.text +="age :="+user.age;               });            }

四、结束语
抽空写了一些WebService资料，周六晚上也没有好好休息，好长时间没有陪儿子好好玩了，明天还得要开会，希望这些心得能对朋友有些帮助。
