asp.net-mvc – 具有长不存在的URL的ASP.NET MVC 5 – (HTTP错误404.0 – 未找到)

我在Microsoft Visual Studio Express 2013 for Web中创建了一个新项目.
它是一个ASP.NET MVC 5 – .NET Framework 4.5项目.

我想要处理(资源无法找到)：

我使用下面的代码处理它.

如果我执行类似(/ Home / kddiede / ddiij)或(/ djdied / djie / djs)的这个代码,这将导致显示我的自定义错误页面.

但是,当我尝试像(/ Home / kddiede / ddiij / dfd / sdfds / dsf / dsfds / fd)等任何长时间不存在的URL时,它会显示：

代码从：http://www.codeproject.com/Articles/635324/Another-set-of-ASP-NET-MVC-4-tips

提示16：自定义错误屏幕

错误页面在/View/Shared/Error.cshtml中

Web.config文件

<system.web>
<customErrors mode="RemoteOnly" />
</system.web>

Global.asax中

protected void Application_EndRequest(Object sender,EventArgs e)
{
    ErrorConfig.Handle(Context);
}

ErrorConfig类

public class ErrorConfig
{
  public static void Handle(HttpContext context)
  {
    switch (context.Response.StatusCode)
    {
      //Not authorized
      case 401:
        Show(context,401);
        break;

      //Not found
      case 404:
        Show(context,404);
        break;
    }
  }

  static void Show(HttpContext context,Int32 code)
  {
    context.Response.Clear();

    var w = new HttpContextwrapper(context);
    var c = new ErrorController() as IController;
    var rd = new RouteData();

    rd.Values["controller"] = "Error";
    rd.Values["action"] = "Index";
    rd.Values["id"] = code.ToString();

    c.Execute(new RequestContext(w,rd));   
  }
}

ErrorController

internal class ErrorController : Controller
{
  [HttpGet]
  public ViewResult Index(Int32? id)
  {
    var statusCode = id.HasValue ? id.Value : 500;
    var error = new HandleErrorInfo(new Exception("An exception with error " + statusCode + " occurred!"),"Error","Index");
    return View("Error",error);
  }
}

来自上述网站的最后一段代码没有添加到Global.asax中,因为它已经在FilterConfig.cs中

public static void RegisterGlobalFilters(GlobalFilterCollection filters)
{
  filters.Add(new HandleErrorAttribute());
}

任何人都知道如何解决它？

提前致谢.

解决方法

解决了.要将所有不存在的网址指向错误页面,请执行以下操作：

>在RouteConfig.cs文件的末尾添加下面的代码：

public static void RegisterRoutes(RouteCollection routes)
{
    // Default
    routes.MapRoute(
        name: "Default",url: "{controller}/{action}/{id}",defaults: new { controller = "Home",action = "Index",id = UrlParameter.Optional }
    );

    // Add this code to handle non-existing urls
    routes.MapRoute(
        name: "404-PageNotFound",// This will handle any non-existing urls
        url: "{*url}",// "Shared" is the name of your error controller,and "Error" is the action/page
        // that handles all your custom errors
        defaults: new { controller = "Shared",action = "Error" }
    );
}

>将以下代码添加到Web.config文件中：

<configuration>
    <system.webServer>
       <modules runAllManagedModulesForAllRequests="true"></modules>
    </system.webServer>

    <system.web>
       <httpRuntime relaxedUrlToFileSystemMapping="true" />
    </system.web>
</configuration>

这应该将所有不存在的URL(/ad/asd/sa/das,d/asd,asd.asd dpwd’= 12 = 2e-21)指向错误页面.
