为什么request.getRemoteAddr()得到的不是数字

为什么使用request.getRemoteAddr()得到的是80:0:0:0:18fc:2f6e:8d18:383d而不是ip地址

Answer 1

获得客户端真实IP二种方法！~
获得客户端真实IP地址的体例一：
　　public String getRemortIP(HttpServletRequest request) {
　　if (request.getHeader("x-forwarded-for") == null) {
　　return request.getRemoteAddr();
　　}
　　return request.getHeader("x-forwarded-for");
　　}
　　获得客户端真实IP地址的体例二：
　　public String getIpAddr(HttpServletRequest request) {
　　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;
　　}
