Asp.net 中mvc 实现超时弹窗后跳转功能
时间：2022-06-25 08:48:15 编辑：袖梨 来源：一聚教程网
为了实现保持登录状态,可以用cookie来解决这一问题
假设过期时间为30分钟,校验发生在服务器,借助过滤器,可以这样写
| 代码如下 | 复制代码 |
|
publicclassPowerFilter : AuthorizeAttribute { publicoverridevoidOnAuthorization(AuthorizationContext filterContext) { var cookie = HttpContext.Current.Request.Cookies["loginInfo"]; if(null== cookie) { filterContext.Result =newRedirectResult("/admin/login/index"); } else { cookie.Expires = DateTime.Now.AddMinutes(30); HttpContext.Current.Response.Cookies.Remove("loginInfo"); HttpContext.Current.Response.Cookies.Add(cookie); } } } | |
但是页面直接跳转了,也没有一个提示,显得不是很友好,可以这样
| 代码如下 | 复制代码 |
|
publicclassPowerFilter : AuthorizeAttribute { publicoverridevoidOnAuthorization(AuthorizationContext filterContext) { var cookie = HttpContext.Current.Request.Cookies["loginInfo"]; if(null== cookie) { filterContext.Result =newContentResult() { Content =string .Format(" ","/admin/login/index") }; } else { cookie.Expires = DateTime.Now.AddMinutes(30); HttpContext.Current.Response.Cookies.Remove("loginInfo"); HttpContext.Current.Response.Cookies.Add(cookie); } } } } | |
但是,假如是ajax请求呢?
| 代码如下 | 复制代码 |
|
publicclassPowerFilter : AuthorizeAttribute { publicoverridevoidOnAuthorization(AuthorizationContext filterContext) { var cookie = HttpContext.Current.Request.Cookies["loginInfo"]; if(null== cookie) { if(!filterContext.HttpContext.Request.IsAjaxRequest()) { filterContext.Result =newContentResult() { Content =string .Format(" ","/admin/login/index") }; } else { filterContext.Result =newJsonResult() { Data =new{ logoff =true,logurl ="/admin/login/index"}, ContentType =null, ContentEncoding =null, JsonRequestBehavior = JsonRequestBehavior.AllowGet }; } } else { cookie.Expires = DateTime.Now.AddMinutes(30); HttpContext.Current.Response.Cookies.Remove("loginInfo"); HttpContext.Current.Response.Cookies.Add(cookie); } } } | |
