我是ASP.NET MVC4的新手,正在学习这门课程。我有一个非常小的错误处理问题。当教师将<customErrors mode = "On"/>
添加到<system.web>
标记中的web.config文件时,他将被重定向到友好错误页面(而不是堆栈跟踪)。
当我做出这个改变时,我仍然被引导到堆栈跟踪“死亡黄页”。
由于我正在努力尽可能彻底地理解这一点,我想我会在这里问。为什么转动<customErrors mode="On"/>
为教师而不是我?
这是我的<system.web>
标记:
<system.web>
<customErrors mode="On"/>
<httpHandlers>
<add path="*" verb="*" type="System.Web.HttpNotFoundHandler"/>
</httpHandlers>
<pages
validateRequest="false"
pageParserFilterType="System.Web.Mvc.ViewTypeParserFilter, System.Web.Mvc, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"
pageBaseType="System.Web.Mvc.ViewPage, System.Web.Mvc, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"
userControlBaseType="System.Web.Mvc.ViewUserControl, System.Web.Mvc, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35">
<controls>
<add assembly="System.Web.Mvc, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" namespace="System.Web.Mvc" tagPrefix="mvc" />
</controls>
</pages>
</system.web>
这是我的Global.asax.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Http;
using System.Web.Mvc;
using System.Web.Optimization;
using System.Web.Routing;
namespace OdeToFood
{
// Note: For instructions on enabling IIS6 or IIS7 classic mode,
// visit http://go.microsoft.com/?LinkId=9394801
public class MvcApplication : System.Web.HttpApplication
{
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
WebApiConfig.Register(GlobalConfiguration.Configuration);
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
RouteConfig.RegisterRoutes(RouteTable.Routes);
BundleConfig.RegisterBundles(BundleTable.Bundles);
AuthConfig.RegisterAuth();
}
}
}
最后,我的FilterConfig.cs
using System.Web;
using System.Web.Mvc;
namespace OdeToFood
{
public class FilterConfig
{
public static void RegisterGlobalFilters(GlobalFilterCollection filters)
{
filters.Add(new HandleErrorAttribute());
}
}
}
我目前有默认视图Error.cshtml。
我也试过
<customErrors mode="On" defaultRedirect="Error"/>
和
<customErrors mode="On" defaultRedirect="~/Error.cshtml"/>
我正在使用此代码来强制错误:
public class CuisineController : Controller
{
//
// GET: /Cuisine/
public ActionResult Search(string name = "french")
{
throw new Exception("Something terrible has happened");
var message = Server.HtmlEncode(name);
return Content(message);
}
}
}
正如你所知,我对此非常陌生,所以如果这是一个无聊的问题我很抱歉,但我正尽力学习。
答案 0 :(得分:4)
您仍需要制作错误页面。例如,
<system.web>
...
<customErrors defaultRedirect="~/Common/Error" mode="On"/>
</system.web>
public class CommonController : Controller
{
// Error
public ActionResult Error()
{
this.Response.StatusCode = 503;
this.Response.TrySkipIisCustomErrors = true;
return View();
}
}
@{
ViewBag.Title = "Error";
}
<h2>@ViewBag.Title</h2>
<p>
Error ...
</p>
