所有极端情况下默认路由 [英] Default route for all extreme situations

问题描述

在我的路由我想有这样的事情没有找到路由处理。

In my routing I would like to have something like not found route handler.

例如我已创建了一个映射像

For example I have created one mapping like

routes.MapRoute(
                     "default",
                     "{controller}/{action}/{id}",
                     new { controller = "Home", action = "Index", id="" }
             );

routes.MapRoute(
                     "Catchall",
                     "{*catchall}",
                     new { controller = "Home", action = "Lost" }
             );

但是，当用户插入解决类似/一/二/三/四/ BLA / BLA将与全部接收映射缓存。

but when user inserts address something like /one/two/three/four/bla/bla it will be cached with the Catchall mapping.

但是，当用户插入的东西，应与默认映射，
（如/一/二/，但这种控制器或者动作不执行）
我想这全部接收映射会接受这一要求，
因为所有其他映射失败。但不是这个，我得到一个错误。

But when user inserts something that should match with default mapping, (like /one/two/ ,but this controller or action is not implemented) I would want that Catchall mapping would accept this request, because all other mappings failed. But instead of this I get an error.

我应该重写某些映射处理程序来捕捉异常，如果控制器或者动作得到一个例外呢？

Should I override some mapping handlers to catch the exception if controller or action getting an exception?

推荐答案

这里的问题是，它不是路由的责任，以确保一/二映射到的文件的。这种责任落到视图引擎。由于一/二是一个有效的路线的，它会被选中。

The issue here is that it's not the Route's responsibility to make sure that "one/two" maps to a file. That responsibility falls to the ViewEngine. Since "one/two" is a valid route, it will be chosen.

如果你想处理一个无效的路线的错误，我会建议你做的仅仅是使用内置的ErrorHandling中页，以显示您将在全部接收所做的任何消息。

If you want to handle the error of an invalid route, what I would recommend you do is simply use the built in ErrorHandling "page" to display whatever message you would have done in the Catchall.
