我希望将所有401错误重定向到自定义错误页面.我最初在web.config中设置了以下条目.
<customErrors defaultRedirect="ErrorPage.aspx" mode="On">
<error statusCode="401" redirect="~/Views/Shared/AccessDenied.aspx" />
</customErrors>
使用IIS Express时,我收到了IIS Express 401错误页面.
如果我不使用IIS Express,则返回空白页面.使用Google Chrome的"网络"标签检查响应,我看到当页面为空白时,标题中会返回401状态
到目前为止我尝试使用的是这个SO答案中的建议,因为我使用的是IIS Express,但无济于事.我尝试过使用组合<custom errors>而<httpErrors>没有运气 - 标准错误或空白页仍然显示.
该httpErrors部分看起来像这样的基础上,瞬间链接从上面的SO问题(我还发现了另一种非常有前途的答案却没有运气-空白响应)
<system.webServer>
<httpErrors errorMode="DetailedLocalOnly" existingResponse="PassThrough" >
<remove statusCode="401" />
<error statusCode="401" path="/Views/Shared/AccessDenied.htm" />
</httpErrors>
<!--
<httpErrors errorMode="Custom"
existingResponse="PassThrough"
defaultResponseMode="ExecuteURL">
<remove statusCode="401" />
<error statusCode="401" path="~/Views/Shared/AccessDenied.htm"
responseMode="File" />
</httpErrors>
-->
</system.webServer>
我甚至已经修改了applicationhost.config文件,并修改<httpErrors lockAttributes="allowAbsolutePathsWhenDelegated,defaultPath">,以<httpErrors lockAttributes="allowAbsolutePathsWhenDelegated">基于从信息iis.net.在我努力的过程中,我也设法偶然发现了另一个SO问题中描述的这个错误.
如何在Asp.Net Mvc 3中显示自定义错误页面？
附加信息
已使用Authorize特定用户的属性修饰了以下控制器操作.
[HttpGet]
[Authorize(Users = "domain\\userXYZ")]
public ActionResult Edit()
{
return GetSettings();
}
[HttpPost]
[Authorize(Users = "domain\\userXYZ")]
public ActionResult Edit(ConfigurationModel model, IList<Shift> shifts)
{
var temp = model;
model.ConfiguredShifts = shifts;
EsgConsole config = new EsgConsole();
config.UpdateConfiguration(model.ToDictionary());
return RedirectToAction("Index");
}

我使用这些步骤:
// in Global.asax.cs:
protected void Application_Error(object sender, EventArgs e) {
var ex = Server.GetLastError().GetBaseException();
Server.ClearError();
var routeData = new RouteData();
routeData.Values.Add("controller", "Error");
routeData.Values.Add("action", "Index");
if (ex.GetType() == typeof(HttpException)) {
var httpException = (HttpException)ex;
var code = httpException.GetHttpCode();
routeData.Values.Add("status", code);
} else {
routeData.Values.Add("status", 500);
}
routeData.Values.Add("error", ex);
IController errorController = new Kavand.Web.Controllers.ErrorController();
errorController.Execute(new RequestContext(new HttpContextWrapper(Context), routeData));
}
protected void Application_EndRequest(object sender, EventArgs e) {
if (Context.Response.StatusCode == 401) { // this is important, because the 401 is not an error by default!!!
throw new HttpException(401, "You are not authorised");
}
}
和:
// in Error Controller:
public class ErrorController : Controller {
public ActionResult Index(int status, Exception error) {
Response.StatusCode = status;
return View(status);
}
protected override void Dispose(bool disposing) {
base.Dispose(disposing);
}
}
和错误文件夹中的索引视图:
@* in ~/Views/Error/Index.cshtml: *@
@model Int32
@{
Layout = null;
}
<!DOCTYPE html>
<html>
<head>
<title>Kavand | Error</title>
</head>
<body>
<div>
There was an error with your request. The error is:<br />
<p style=" color: Red;">
@switch (Model) {
case 401: {
<span>Your message goes here...</span>
}
break;
case 403: {
<span>Your message goes here...</span>
}
break;
case 404: {
<span>Your message goes here...</span>
}
break;
case 500: {
<span>Your message goes here...</span>
}
break;
//and more cases for more error-codes...
default: {
<span>Unknown error!!!</span>
}
break;
}
</p>
</div>
</body>
</html>
和 - 最后一步:
<!-- in web.config: -->
<customErrors mode="Off"/>

我无法在web.config和MVC中获得CustomErrors以便一起玩,所以我放弃了.我这样做了.
在global.asax中:
protected void Application_Error()
{
var exception = Server.GetLastError();
var httpException = exception as HttpException;
Response.Clear();
Server.ClearError();
var routeData = new RouteData();
routeData.Values["controller"] = "Errors";
routeData.Values["action"] = "General";
routeData.Values["exception"] = exception;
Response.StatusCode = 500;
if (httpException != null)
{
Response.StatusCode = httpException.GetHttpCode();
switch (Response.StatusCode)
{
case 403:
routeData.Values["action"] = "Http403";
break;
case 404:
routeData.Values["action"] = "Http404";
break;
}
}
// Avoid IIS7 getting in the middle
Response.TrySkipIisCustomErrors = true;
IController errorsController = new GNB.LG.StrategicPlanning.Website.Controllers.ErrorsController();
HttpContextWrapper wrapper = new HttpContextWrapper(Context);
var rc = new RequestContext(wrapper, routeData);
errorsController.Execute(rc);
}
在ErrorsController中:
public class ErrorsController
{
public ActionResult General(Exception exception)
{
// log the error here
return View(exception);
}
public ActionResult Http404()
{
return View("404");
}
public ActionResult Http403()
{
return View("403");
}
}
在web.config中:
<customErrors mode="Off" />
无论在何处或如何创建错误,这对我都有用.401现在不在那里处理,但你可以很容易地添加它.
也许我错过了一些东西,但MVC有一个ErrorHandlerAttribute使用自定义错误的默认全局.这个解释相当不错这里.
public static void RegisterGlobalFilters(GlobalFilterCollection filters)
{
filters.Add(new HandleErrorAttribute());
}
您需要做的就是custom errors在配置中打开,然后设置自定义错误重定向,最好是静态HTML文件(如果应用程序出错).
<customErrors mode="On" defaultRedirect="errors.htm">
<error statusCode="404" redirect="errors404.htm"/>
</customErrors>
如果您愿意,也可以指向自定义Controller以显示错误.在下面的示例中,我刚使用默认路由到Controller命名Error,并调用了一个操作Index,并且命名了字符串参数id(以接收错误代码).你当然可以使用你想要的任何路由.您的示例无效,因为您尝试直接链接到Views目录而不通过Controller.MVC .NET不Views直接向文件夹提供请求.
<customErrors mode="On" defaultRedirect="/error/index/500">
<error statusCode="404" redirect="/error/index/404"/>
</customErrors>
该ErrorHandlerAttribute还可以广泛地使用Controllers/Actions重定向错误名为Views有关Controller.例如,要显示出现类型异常时的View命名MyArgumentError,ArgumentException您可以使用:
[ControllerAction,ExceptionHandler("MyArgumentError",typeof(ArgumentException))]
public void Index()
{
// some code that could throw ArgumentExcepton
}
当然另一种选择是更新库存Error页面Shared.
