当文件实际存在于指定位置时的 MVC 路由 [英] MVC routing when a file actually exists at the specified location

问题描述

所以我在 IIS 7 下运行的 MVC 3 应用程序中有这样的路由:

So I have a route like this in my MVC 3 application running under IIS 7:

routes.MapRoute(
               "VirtualTourConfig",
               "virtualtour/config.xml",
               new { controller = "VirtualTour", action = "Config" }
               );

诀窍在于/virtualtour/config.xml 中确实存在一个文件.似乎请求只是返回该位置的 xml 文件，而不是访问处理 XML、进行一些更改并返回自定义 XmlResult 的路由.

The trick is that a file actually exists at /virtualtour/config.xml. It seems like the request is just returning the xml file at that location instead of hitting the route, which processes the XML, makes some changes and returns a custom XmlResult.

如果文件存在于磁盘上，关于如何告诉我的应用程序点击路由而不是实际文件的任何建议?

Any suggestions on how I can tell my application to hit the route and not the actual file in the event that the file exists on disk?

看来我可以在 Global.asax 的 RegisterRoutes 方法中使用 routes.RouteExistingFiles = true; 来告诉应用程序忽略磁盘上的文件.然而，这会全局设置标志并破坏应用程序中的许多其他请求.例如，我仍然希望调用/assets/css/site.css 来返回 CSS 文件，而不必为每个静态资产专门设置路由.所以现在问题变成了，有没有办法在每条路线的基础上做到这一点?

It appears that I can use routes.RouteExistingFiles = true; in the RegisterRoutes method of Global.asax to tell the application to ignore files on disk. This, however, sets the flag globally and breaks a lot of other requests within the application. For example, I still want calls to /assets/css/site.css to return the CSS file without having to specifically set routes up for each static asset. So now the question becomes, is there a way to do this on a per-route basis?

推荐答案

到目前为止，我发现的最佳答案是全局应用 routes.RouteExistingFiles=true 然后有选择地忽略路由我想传递到现有文件，如 .js、.css 等.所以我最终得到了这样的东西:

So far the best answer to this that I have found is to globally apply routes.RouteExistingFiles=true and then selectively ignore the routes I want to pass through to existing files like .js, .css, etc. So I ended up with something like this:

public static void RegisterRoutes(RouteCollection routes)
        {
            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
            routes.IgnoreRoute("*.js|css|swf");
            routes.RouteExistingFiles = true;

            routes.MapRoute(
               "VirtualTourConfig",
               "virtualtour/config.xml",
               new { controller = "VirtualTour", action = "Config" }
               );
}

如果有人有更好的解决方案，我想看看.我更喜欢有选择地将RouteExistingFIles"标志应用于个别路线，但我不知道是否有办法做到这一点.

If anyone has a better solution, I'd like to see it. I'd much prefer to selectively apply an "RouteExistingFIles" flag to individual routes but I don't know if there's a way to do that.
