泛微 EC9 中获取 IP 的两段 JSP 代码：一段用 InetAddress 取本机服务器 IP，便于在集群环境下确认请求落在哪台节点；另一段在登录态下输出 x-forwarded-for、getRemoteAddr、Util.getIpAddr 等取值，并遍历全部请求头，用于排查 OA 获取用户 IP 不准确的问题。

获取服务器IP地址

常用于集群环境下查看访问的是哪个服务器～

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@ page language="java" import="java.net.InetAddress" %>
<%
    out.println("=====本机ip地址======<br>");
    InetAddress ia = InetAddress.getLocalHost();
    String hostaddr = ia.getHostAddress();
    out.println(hostaddr);

%>

获取用户到达服务器的ip地址

常用于排查 OA 系统获取用户 IP 不准确的问题

<%@ page language="java" contentType="text/html; charset=GBK" %>
<%@ page import="java.io.*" %>
<%@ page import="java.net.*" %>
<%@ page import="java.util.*,weaver.general.Util" %>
<%@ include file="/systeminfo/init_wev8.jsp" %>

    out.println("getRemoteAddr::::"+request.getRemoteAddr()+"<br/>");
    out.println("Util.getIpAddr()::::"+Util.getIpAddr(request)+"<br/>");
    out.println("request::::"+request);

    out.println("<br/><br/>-----------------------------headers----------------<br/>");
    Enumeration headers = request.getHeaderNames();
    while(headers.hasMoreElements()){
      String header = ""+headers.nextElement();
      //out.println("*********"+header+"---->"+request.getHeader(header)+"<br/>");
      Enumeration headerValues = request.getHeaders(header);
      while(headerValues.hasMoreElements()){
        String headerValue = ""+headerValues.nextElement();
        out.println("*********"+header+"---->"+headerValue+"<br/>");
      }
    }


    out.println("<br/><br/>-----------------------------header----------------<br/>");
    Enumeration headerValues = request.getHeaders("x-forwarded-for");

    while(headerValues.hasMoreElements()){
        String headerValue = ""+headerValues.nextElement();
        out.println("*********x-forwarded-for---->"+headerValue+"<br/>");
      }
