ASP.NET MVC Custom Error Pages with Magical Unicorn
- by FLClover
my question is regarding Pure.Kromes answer to this post. I tried implementing my pages' custom error messages using his method, yet there are some problems I can't quite explain.
a)
When I provoke a 404 Error by entering in invalid URL such as localhost:3001/NonexistantPage, it defaults to the ServerError() Action of my error controller even though it should go to NotFound(). Here is my ErrorController:
public class ErrorController : Controller
{
public ActionResult NotFound()
{
Response.TrySkipIisCustomErrors = true;
Response.StatusCode = (int)HttpStatusCode.NotFound;
var viewModel = new ErrorViewModel()
{
ServerException = Server.GetLastError(),
HTTPStatusCode = Response.StatusCode
};
return View(viewModel);
}
public ActionResult ServerError()
{
Response.TrySkipIisCustomErrors = true;
Response.StatusCode = (int)HttpStatusCode.InternalServerError;
var viewModel = new ErrorViewModel()
{
ServerException = Server.GetLastError(),
HTTPStatusCode = Response.StatusCode
};
return View(viewModel);
}
}
My error routes in Global.asax.cs:
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.IgnoreRoute("{*favicon}", new { favicon = @"(.*/)?favicon.ico(/.*)?" });
routes.MapRoute(
name: "Error - 404",
url: "NotFound",
defaults: new { controller = "Error", action = "NotFound" }
);
routes.MapRoute(
name: "Error - 500",
url: "ServerError",
defaults: new { controller = "Error", action = "ServerError" }
);
And my web.config settings:
<system.web>
<customErrors mode="On" redirectMode="ResponseRewrite" defaultRedirect="/ServerError">
<error statusCode="404" redirect="/NotFound" />
</customErrors>
...
</system.web>
<system.webServer>
<httpErrors errorMode="Custom" existingResponse="Replace">
<remove statusCode="404" subStatusCode="-1" />
<error statusCode="404" path="/NotFound" responseMode="ExecuteURL" />
<remove statusCode="500" subStatusCode="-1" />
<error statusCode="500" path="/ServerError" responseMode="ExecuteURL" />
</httpErrors>
...
The Error views are located in /Views/Error/ as NotFound.cshtml and ServerError.cshtml.
b)
One funny thing is, When a server error occurs, it does in fact display the Server Error view I defined, however it also outputs a default error message as well saying that the Error page could not be found.
Here's how it looks like:
Do you have any advice how I could fix these two problems? I really like Pure.Kromes approach to implementing these error messages, but if there are better ways of achieving this don't hestitate to tell me.
Thanks!
*EDIT : *
I can directly navigate to my views through the ErrorController by accessing /Error/NotFound or Error/ServerError.
The views themselves only contain some text, no markup or anything.
As I said, it actually works in some way, just not the way I intended it to work. There seems to be an issue with the redirect in the web.config, but I haven't been able to figure it out.
