夜之末: 楼楼，获取请求ip可以这么写吗[code=java] public static String getIpAddr(HttpServletRequest request) { if (request == null) { return "unknown"; } String ip = null; String[] headers = { "x-forwarded-for", "Proxy-Client-IP", "X-Forwarded-For", "WL-Proxy-Client-IP", "X-Real-IP"}; for (String header : headers) { ip = request.getHeader(header); if (ip != null && ip.length() != 0 && !ip.equalsIgnoreCase("unknown")) { break; } } if (ip == null || ip.length() == 0 || ip.equalsIgnoreCase("unknown")) { ip = request.getRemoteAddr(); } return "0:0:0:0:0:0:0:1".equals(ip) ? "127.0.0.1" : EscapeUtil.clean(ip); } [/code]
