//控制器中直接用即可取IP   ViewBag.ip = HttpContext.GetClientIP();   public static class HttpContextExtension  {      public static string GetClientIP(this HttpContext context)      {          var ip = context.Request.Headers["Cdn-Src-Ip"].FirstOrDefault();          if (!string.IsNullOrEmpty(ip))              return IpReplace(ip);            ip = context.Request.Headers["X-Forwarded-For"].FirstOrDefault();          if (!string.IsNullOrEmpty(ip))              return IpReplace(ip);            ip = context.Connection.RemoteIpAddress.ToString();            return IpReplace(ip);      }        static string IpReplace(string inip)      {          //::ffff:          //::ffff:192.168.2.131 这种IP处理          if (inip.Contains("::ffff:"))          {              inip = inip.Replace("::ffff:", "");          }          return inip;      }  }
