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
