关于web请求中 获取真实IP
HttpRequest request = HttpContext.Current.Request; if (!string.IsNullOrEmpty(request.ServerVariables["HTTP_X_FORWARDED_FOR"])) { //ip = GetCDNIP(request.ServerVariables["HTTP_ARR_IP"]); if (string.IsNullOrEmpty(ip)) { ip = request.ServerVariables["HTTP_X_FORWARDED_FOR"].ToString().Split(',')[0].Trim(); } } if (string.IsNullOrEmpty(ip) || ip.Split(new char[] { '.' }, StringSplitOptions.RemoveEmptyEntries).Length != 4) { ip = GetArrIP(); if (!string.IsNullOrWhiteSpace(ip) && ip.Split(new char[] { '.' }, StringSplitOptions.RemoveEmptyEntries).Length != 4) { ip = string.Empty; } } //if (string.IsNullOrEmpty(ip)) //{ // ip = GetCDNIP(null); //} if (string.IsNullOrEmpty(ip)) { ip = HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"]; } if (string.IsNullOrEmpty(ip)) { ip = request.UserHostAddress; }
