我在ASP.NET MVC 5应用程序中使用自定义授权属性，如下所示：
public class CustomAuthorizeAttribute : AuthorizeAttribute
{
protected override void HandleUnauthorizedRequest(AuthorizationContext context)
{
if (context.HttpContext.Request.IsAuthenticated)
{
context.Result = new System.Web.Mvc.HttpStatusCodeResult((int)System.Net.HttpStatusCode.Forbidden);
}
else
{
base.HandleUnauthorizedRequest(context);
}
}
}
在我的web.config的system.web部分我提到了错误路径，如：
<system.web>
<customErrors mode="On" defaultRedirect="/Error/Error">
<error statusCode="403" redirect="/Error/NoPermissions"/>
</customErrors>
</system.web>
但是我从未重定向到/ Error / NoPermissions的自定义错误页面。相反，浏览器会显示“HTTP错误403.0 – 禁止”的常规错误页面。
解决方法
[1]：删除所有’customErrors’&来自Web.config的’httpErrors’
[2]：检查’App_Start / FilterConfig.cs’如下所示：
public class FilterConfig
{
public static void RegisterGlobalFilters(GlobalFilterCollection filters)
{
filters.Add(new HandleErrorAttribute());
}
}
public void Application_Error(Object sender,EventArgs e)
{
Exception exception = Server.GetLastError();
Server.ClearError();
var routeData = new RouteData();
routeData.Values.Add("controller","ErrorPage");
routeData.Values.Add("action","Error");
routeData.Values.Add("exception",exception);
if (exception.GetType() == typeof(HttpException))
{
routeData.Values.Add("statusCode",((HttpException)exception).GetHttpCode());
}
else
{
routeData.Values.Add("statusCode",500);
}
Response.TrySkipIisCustomErrors = true;
IController controller = new ErrorPageController();
controller.Execute(new RequestContext(new HttpContextWrapper(Context),routeData));
Response.End();
}
[4]：添加“控制器/ ErrorPageController.cs”
public class ErrorPageController : Controller
{
public ActionResult Error(int statusCode,Exception exception)
{
Response.StatusCode = statusCode;
ViewBag.StatusCode = statusCode + " Error";
return View();
}
}
[5]：在“Views / Shared / Error.cshtml”
@model System.Web.Mvc.HandleErrorInfo
@{
ViewBag.Title = (!String.IsNullOrEmpty(ViewBag.StatusCode)) ? ViewBag.StatusCode : "500 Error";
}
<h1 class="error">@(!String.IsNullOrEmpty(ViewBag.StatusCode) ? ViewBag.StatusCode : "500 Error"):</h1>
//@Model.ActionName
//@Model.ControllerName
//@Model.Exception.Message
//@Model.Exception.StackTrace
：D
