获取IP地址 & 伪装IP地址发送请求

//获取请求客户端IP地址 　　

public final static String getIpAddress(HttpServletRequest request) throws IOException {
         // 获取请求主机IP地址,如果通过代理进来，则透过防火墙获取真实IP地址
         String ip = request.getHeader("X-Forwarded-For");
         if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
             if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
                 ip = request.getHeader("Proxy-Client-IP");
             }
