本文介绍了一个使用Flash技术实现的客户端IP地址获取服务。通过HTTPService组件向指定的Java后端发送POST请求，来获取客户端的IP地址。文章展示了完整的Flex与Java代码实现，并通过弹窗显示请求结果。

<mx:HTTPService id="clientIpDs"
    url="http://192.168.10.135:8080/flcds/getIP.jsp"
    useProxy="false" showBusyCursor="true"
    resultFormat="text" method="POST"
    result="dealResult(event)"
    fault="alss(event)">
</mx:HTTPService>

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String clientIP = request.getRemoteHost();
response.getWriter().print(clientIP); 
%>

<mx:Script>
