flex4.5+php5.2+amfphp通过RemoteObject交互

偶尔写写php感觉心情还是蛮舒畅的（Java里的Struts+Hibernate+Spring写久了），写写php才知道，这种被解放的感觉真好。不得不说，php是一种服务器端比较精辟的语言，难怪崇拜者这么多。就来整整flex基于php的交互，看好了，这里要介绍的不是通过flex里面的HttpService组件与php交互，而是借助AMFPHP通过RemoteObject方式来交互。
关于amfphp环境的搭建，请参考本人写的amfphp环境搭建教程，当然里面写的比较粗略，有不清粗的可以联系我。
先来看看php端代码
ProductServices.php

<? php
class ProductServices{
     /* *
    *query product list
     */
     function getProductList(){
         $link = @ mysql_connect ( " localhost " , " root " , "" ) or die ( " Could not connect " );
         mysql_select_db ( " compass " , $link );
         mysql_query ( " set names utf8 " , $link );
         $result = mysql_query ( " SELECT * FROM product " , $link );
         $array = array ();
         while ( $row = mysql_fetch_array ( $result , MYSQL_ASSOC)) {
             array_push ( $array , $row );
        }
         mysql_free_result ( $result );
         mysql_close ( $link );
         return $array ;
    }

     function findProductById( $id ){
         $link = @ mysql_connect ( " localhost " , " root " , "" ) or die ( " Could not connect " );
         mysql_select_db ( " compass " , $link );
         mysql_query ( " set names utf8 " , $link );
         $result = mysql_query ( " SELECT * FROM product where id= " . $id , $link );
         $array = array ();
         while ( $row = mysql_fetch_array ( $result , MYSQL_ASSOC)) {
             array_push ( $array , $row );
        }
         mysql_free_result ( $result );
         mysql_close ( $link );
         return $array ;
    }

}
?>

在ProductServices.php文件中，定义了一个类ProductServices，里面封装了两个方法，getProductList（），findProductById（$id）里面内容很简单，一个是全部查询商品，一个是根据Id查询商品

注意该文件存放的位置C:\inetpub\wwwroot\amfphp\services\ 这样可以被amfphp的资源管理器检索到

编写flex端代码

<? xml version = " 1.0 " encoding = " utf-8 " ?>
< s:Application xmlns:fx = " http://ns.adobe.com/mxml/2009 "
               xmlns:s = " library://ns.adobe.com/flex/spark "
               xmlns:mx = " library://ns.adobe.com/flex/mx " minWidth = " 955 " minHeight = " 600 "
               creationComplete = " ro.getOperation('getProductList').send() "
                >
     
     < fx:Declarations >
         

         < s:RemoteObject id = " ro "
                        destination = " amfphp "
                        source = " ProductServices "
                        fault = " getProductList_faultHandler(event) "
                        result = " getProductList_resultHandler(event) "
                        endpoint = " http://192.168.3.11/amfphp/gateway.php " >
         </ s:RemoteObject >

         

     </ fx:Declarations >

     < fx:Script >
         <! [CDATA[
            import mx.collections.ArrayCollection;
            import mx.controls.Alert;
            import mx.rpc.events.FaultEvent;
            import mx.rpc.events.ResultEvent;
            import mx.utils.ArrayUtil;

            [Bindable]
            internal var dp:ArrayCollection;



             // amfphp请求成功时调用方法
            protected function getProductList_resultHandler(event:ResultEvent): void
            {
                dp = new ArrayCollection(ArrayUtil.toArray(event.result));
            }
             // amfphp请求失败时调用方法
            protected function getProductList_faultHandler(event:FaultEvent): void
            {
                Alert.show( " 失败了 " ,event.fault.message);
            }

        ]] >
     </ fx:Script >


     < s:layout >
         < s:HorizontalLayout />
     </ s:layout >
     < s:DataGrid width = " 519 " height = " 292 " dataProvider = " {dp} " requestedRowCount = " 4 " >
         < s:columns >
             < s:ArrayList >
                 < s:GridColumn dataField = " id " headerText = " 编号 " ></ s:GridColumn >
                 < s:GridColumn dataField = " name " headerText = " 商品名称 " ></ s:GridColumn >
                 < s:GridColumn dataField = " price " headerText = " 单价 " ></ s:GridColumn >
                 < s:GridColumn dataField = " descption " headerText = " 描述 " ></ s:GridColumn >
             </ s:ArrayList >
         </ s:columns >
     </ s:DataGrid >

</ s:Application >

必须在flex工程的src目录下存放一个名为services-config.xml

<? version="1.0" encoding="UTF-8" ?>
< services-config >
     < services >
         < service id ="sabreamf-flashremoting-service"
                 class ="flex.messaging.services.RemotingService"
                 messageTypes ="flex.messaging.messages.RemotingMessage" >
             < destination id ="amfphp" >
                 < channels >
                     < channel ref ="my-amfphp" />
                 </ channels >
                 < properties >
                     < source > * </ source >
                 </ properties >
             </ destination >
         </ service >
     </ services >

     < channels >
         < channel-definition id ="my-amfphp" class ="mx.messaging.channels.AMFChannel" >
             < endpoint uri ="http://192.168.3.11/amfphp/gateway.php" class ="flex.messaging.endpoints.AMFEndpoint" />
         </ channel-definition >
     </ channels >
</ services-config >

需要将该文件编译到环境中去
