在JSP里,获取客户端的IP地址的方法是:request.getRemoteAddr(),这种方法在大部分情况下都是有效的。但是在通过了 Apache,Squid等反向代理软件就不能获取到客户端的真实IP地址了。如果使用了反向代理软件,用 request.getRemoteAddr()方法获取的IP地址是:127.0.0.1或 192.168.1.110,而并不是客户端的真实IP。
在实习公司看到的一个方法:
[java] view plaincopyprint?
- /**
- * 获取Ip地址
- * @return
- */
- protected String getIpAddr() {
- HttpServletRequest request = ServletActionContext.getRequest();
- 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.getRemoteAddr();
- }
- return ip;
- }
