jsp获取客户端IP地址的方法
本文实例讲述了jsp获取客户端IP地址的方法。分享给大家供大家参考,具体如下:
publicstaticStringgetIpAddr(HttpServletRequestrequest){ Stringip=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(); } returnip; }
希望本文所述对大家JSP程序设计有所帮助。
