自定义错误处理程序仍然加载默认错误

我使用此帖Link中的解决方案将我的应用程序的错误处理拼接在一起。我得到的问题是该应用程序仍然路由到默认错误页面。当我断点时,代码一直到Global.asax,但是当应该加载视图自定义错误页面时,它会从解决方案加载默认错误页面。我试图删除默认错误页面,然后我从IIS获得黄色错误页面。不知疲倦地搜索网络,但没有结果。感谢所有的帮助。如果您认为我可以更好地调整问题或标题,我愿意接受建议。

错误控制器:

public class ErrorController : Controller
{
    public ActionResult PageNotFound(Exception ex)
    {
        Response.StatusCode = 404;
        return View("Error", ex);
    }

    public ActionResult ServerError(Exception ex)
    {
        Response.StatusCode = 500;
        return View("Error", ex);
    }

    public ActionResult UnauthorisedRequest(Exception ex)
    {
        Response.StatusCode = 403;
        return View("Error", ex);
    }

    //Any other errors you want to specifically handle here.

    public ActionResult CatchAllUrls()
    {
        //throwing an exception here pushes the error through the Application_Error method for centralised handling/logging
        throw new HttpException(404, "The requested url " + Request.Url.ToString() + " was not found");
    }
}

Global.asax.cs中的代码:

    protected void Application_Error(object sender, EventArgs e)
    {
        Exception exception = Server.GetLastError();

        //Error logging omitted

        HttpException httpException = exception as HttpException;
        RouteData routeData = new RouteData();
        IController errorController = new Controllers.ErrorController();
        routeData.Values.Add("controller", "Error");
        routeData.Values.Add("area", "");
        routeData.Values.Add("ex", exception);

        if (httpException != null)
        {
            //this is a basic example of how you can choose to handle your errors based on http status codes.
            switch (httpException.GetHttpCode())
            {
                case 404:
                    Response.Clear();

                    // page not found
                    routeData.Values.Add("action", "PageNotFound");

                    Server.ClearError();
                    // Call the controller with the route
                    errorController.Execute(new RequestContext(new HttpContextWrapper(Context), routeData));

                    break;
                case 500:
                    // server error
                    routeData.Values.Add("action", "ServerError");

                    Server.ClearError();
                    // Call the controller with the route
                    errorController.Execute(new RequestContext(new HttpContextWrapper(Context), routeData));
                    break;
                case 403:
                    // server error
                    routeData.Values.Add("action", "UnauthorisedRequest");

                    Server.ClearError();
                    // Call the controller with the route
                    errorController.Execute(new RequestContext(new HttpContextWrapper(Context), routeData));
                    break;
                //add cases for other http errors you want to handle, otherwise HTTP500 will be returned as the default.
                default:
                    // server error
                    routeData.Values.Add("action", "ServerError");

                    Server.ClearError();
                    // Call the controller with the route
                    errorController.Execute(new RequestContext(new HttpContextWrapper(Context), routeData));
                    break;
            }
        }
        //All other exceptions should result in a 500 error as they are issues with unhandled exceptions in the code
        else
        {
            routeData.Values.Add("action", "ServerError");
            Server.ClearError();
            // Call the controller with the route
            errorController.Execute(new RequestContext(new HttpContextWrapper(Context), routeData));
        }
    }

RouteConfig.cs

  routes.MapRoute("CatchAllUrls", "{*url}", new {controller = "Error", action = "CatchAllUrls"});

捕获块:

throw new HttpException(404, "Unable to write to list" + ", " +  e.InnerException);

在@GeorgPatscheider和@AliAshraf的帮助下,我终于解决了我的问题。我通过更改此返回视图(“错误”,ex.Message)使其工作;到此返回视图(“错误”,ex);并添加了<customErrors mode="On"/>。现在我还可以添加其他HTTP错误代码。在初始帖子之后我已将Message添加到ex感谢所有帮助!!!
