Nutz如何获取客户的IP地址？

抄了一段代码，不知道科学不

	public String userInfo(@Param("data") String data,
			HttpServletRequest req){
		String ip = req.getHeader("x-forwarded-for");
		if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
			ip = req.getHeader("Proxy-Client-IP");
		}
		if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
			ip = req.getHeader("WL-Proxy-Client-IP");
		}
		if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
			ip = req.getRemoteAddr();
		}
		return ip;
	}

@wendal 有人提出Lang.getIP()?

何不点开getIp方法，看看里面如何实现的？

code:

@At("/user/login")
    @Ok("json")
    public Object login(@Param("..") UserEntity user, HttpServletRequest req) {
        System.out.println(Lang.getIP(req));
}
