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.
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
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：
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" }
);
}
<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.
