我需要在JSP页面中获取客户端的IP地址。我尝试了以下方法：

I need to get the IP address of the client in the JSP page. I have tried the following ways:

request.getRemoteAddr() request.getHeader("X_FORWARDED_FOR") request.getHeader("HTTP_CLIENT_IP") request.getHeader("WL-Proxy-Client-IP") request.getHeader("Proxy-Client-IP") request.getHeader("REMOTE_ADDR")

但是，这些方法都没有返回所需的IP地址。如何在JSP页面中获取客户端的IP地址？

However, none of those ways did return the desired IP address. How do I get the IP address of the client in the JSP page?

推荐答案

要获取客户端的IP地址，我'使用以下方法

To get IP address of the client, I've used the following method

<% String ip = request.getHeader("X-Forwarded-For"); if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) { ip = request.getHeader("Proxy-Client-IP"); } if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) { ip = request.getHeader("WL-Proxy-Client-IP"); } if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) { ip = request.getHeader("HTTP_CLIENT_IP"); } if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) { ip = request.getHeader("HTTP_X_FORWARDED_FOR"); } if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) { ip = request.getRemoteAddr(); } %>
