问题描述
我刚起步的ASP.NET MVC如此忍受我。我周围中搜索这个网站和各种人,并看到的这几个实现。
I am just getting started on ASP.NET MVC so bear with me. I've searched around this site and various others and have seen a few implementations of this.
编辑:我忘了,更不用说我使用RC2
I forgot to mention I am using RC2
使用URL路由:
routes.MapRoute(
"Error",
"{*url}",
new { controller = "Errors", action = "NotFound" } // 404s
);
以上似乎照顾(由最初的MVC项目假设默认路由表设置)像这样的请求:/等等/等等/等等/等等
The above seems to take care of requests like this (assuming default route tables setup by initial MVC project): "/blah/blah/blah/blah"
重载HandleUnknownAction()在控制器中:
// 404s - handle here (bad action requested
protected override void HandleUnknownAction(string actionName) {
ViewData["actionName"] = actionName;
View("NotFound").ExecuteResult(this.ControllerContext);
}
然而,previous策略不处理到一个坏/未知控制器的请求。例如,我没有一个/ IDoNotExist,如果我要求这一点,我从Web服务器获取通用404页面,而不是我的404,如果我使用路由+覆盖。
However the previous strategies do not handle a request to a Bad/Unknown controller. For example, I do not have a "/IDoNotExist", if I request this I get the generic 404 page from the web server and not my 404 if I use routing + override.
所以最后,我的问题是:有没有办法使用MVC框架的路由或别的东西,赶上这种类型的请求本身的
So finally, my question is: Is there any way to catch this type of request using a route or something else in the MVC framework itself?
或者我应该只是默认使用Web.Config中的customErrors作为我404处理器,忘记了这一切?我想如果我去的customErrors我不得不通用的404页存储/浏览次数之外,由于直接访问的Web.Config限制。反正任何最佳做法或指导AP preciated。
OR should I just default to using Web.Config customErrors as my 404 handler and forget all this? I assume if I go with customErrors I'll have to store the generic 404 page outside of /Views due to the Web.Config restrictions on direct access. Anyway any best practices or guidance is appreciated.

下面是我如何处理HTTP异常:
Here's how I handle http exceptions:
protected void Application_Error(object sender, EventArgs e)
{
Exception exception = Server.GetLastError();
// Log the exception.
ILogger logger = Container.Resolve<ILogger>();
logger.Error(exception);
Response.Clear();
HttpException httpException = exception as HttpException;
RouteData routeData = new RouteData();
routeData.Values.Add("controller", "Error");
if (httpException == null)
{
routeData.Values.Add("action", "Index");
}
else //It's an Http Exception, Let's handle it.
{
switch (httpException.GetHttpCode())
{
case 404:
// Page not found.
routeData.Values.Add("action", "HttpError404");
break;
case 500:
// Server error.
routeData.Values.Add("action", "HttpError500");
break;
// Here you can handle Views to other error codes.
// I choose a General error template
default:
routeData.Values.Add("action", "General");
break;
}
}
// Pass exception details to the target error View.
routeData.Values.Add("error", exception);
// Clear the error on server.
Server.ClearError();
// Avoid IIS7 getting in the middle
Response.TrySkipIisCustomErrors = true;
// Call target Controller and pass the routeData.
IController errorController = new ErrorController();
errorController.Execute(new RequestContext(
new HttpContextWrapper(Context), routeData));
}
