flex端发送字符串到服务器端生成文件的例子(flex中得到request对象的方法)

flex端的核心代码：
<mx:RemoteObject id="service" destination="StudentService" fault="{failure();}" concurrency="single"> <mx:method name="wrtieToFile" result="{writeFileResult(event)}"/> </mx:RemoteObject> <mx:Script><!--[CDATA[ private function failure():void { Alert.show("加载数据失败"); } public function writeFile():void{ service.wrtieToFile(_textArea.text); } public function writeFileResult(event:ResultEvent):void{ Alert.show(event.result.toString()); } ]]--></mx:Script> <mx:Button x="406" y="176" label="写文件" click="{writeFile();}"/><mx:TextArea x="219" y="214" width="349" height="160" id="_textArea"/>

 

java服务器端核心代码:

 @SuppressWarnings("deprecation") public String wrtieToFile(String context){ String filePath = ""; try { context = new String(context.getBytes("utf-8")); HttpServletRequest request = FlexContext.getHttpRequest(); String path = request.getRealPath("/"); filePath = path + "workflow.xml"; FileWriter fw = new FileWriter(filePath); BufferedWriter bw = new BufferedWriter(fw); bw.write(context); bw.close(); } catch(Exception ex){ ex.printStackTrace(); } return filePath; }  

注意：字符集的编码问题
