Http从request中获取客户端IP地址

文章目录

前言

因为想记录客户端请求的IP地址,故记录如下所示

一、实现方式

实现方式主要分为以下两步

  1. 获取HttpServletRequest
    直接看代码即可,如下所示:
ServletRequestAttributes attributes = (ServletRequestAttributes)RequestContextHolder.getRequestAttributes();
HttpServletRequest request = attributes.getRequest();
  1. 获取IP地址(已考虑反向代理的情况)
    实现如下所示:
public static String getIpAddr(HttpServletRequest request)
    { 
        if (request == null)
        { 
            return "unknown";
        }
        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("X-Forwarded-For");
        }
        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("X-Real-IP");
        }

        if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip))
        { 
            ip = request.getRemoteAddr();
        }

        return "0:0:0:0:0:0:0:1".equals(ip) ? "127.0.0.1" : ip;
    }

二、总结

都看到这里啦~说明你也和我一样热爱技术、善于发掘问题的根源,不妨给我的博客点个赞8

最后我给我自己的开源项目【简帐】打个广告(后端、前端、小程序三端开源),如果star超过20个我就出一个从零开始的教程
