C# MVC 权限过滤器

实现需求：验证Token是否有效，重写状态码和返回内容

  /// <summary>
        /// 权限过滤器，验证Token是否有效
        /// </summary>
        /// <param name="filterContext"></param>
        protected override void HandleUnauthorizedRequest(AuthorizationContext filterContext)
        {
            filterContext.HttpContext.Response.StatusCode = 403;
            string token = filterContext.HttpContext.Request.Headers["token"];

            if (string.IsNullOrWhiteSpace(token))
            {
                filterContext.Result = new JsonResult
                {
                    Data = new { IsSuccess = false, Message = "权限验证失败!" },
                    JsonRequestBehavior = JsonRequestBehavior.AllowGet
                };
            }
            return;
        }

返回内容

2、重写AuthorizeCore，实现权限验证

   protected override bool AuthorizeCore(HttpContextBase httpContext)
        {
            if (string.IsNullOrEmpty(httpContext.Request.Headers["token"]))
            {
                httpContext.Response.StatusCode = 401;//无权限状态码
                return false;
            }
            return true;
        }
