授权过滤器:
/// <summary> /// 授权过滤器 /// </summary> public class TestAuthorizeAttribute:AuthorizeAttribute { public override void OnAuthorization(AuthorizationContext filterContext) { filterContext.HttpContext.Response.Write("OnAuthorization<br/>"); //注释掉父类方法,因为父类里的 OnAuthorization 方法会调用ASP.NET的授权验证机制 //base.OnAuthorization(filterContext); } }
异常过滤器:
public class TestHandleErrorAttribute:HandleErrorAttribute { public override void OnException(ExceptionContext filterContext) { //1.获取一场对象 Exception ex = filterContext.Exception; //2.记录一场日志 //3.重定向友好页面 filterContext.Result = new RedirectResult("~/err.html"); //4.标记一场已经处理完毕 filterContext.ExceptionHandled = true; base.OnException(filterContext); } }
当然,可以在FilterConfig.cs中进行全局过滤
filters.Add(new TestAuthorizeAttribute()); filters.Add(new TestHandleErrorAttribute());
注:如果自定义错误页面没有自动跳转的话
需要去WebConfig配置文件中的<system.web>节点下添加
<customErrors mode="On"></customErrors>
