带有默认控制器的 ASP.NET MVC 路由 [英] ASP.NET MVC Routing with Default Controller

问题描述

对于一个场景，我有一个 ASP.NET MVC 应用程序，其 URL 如下所示:

For a scenario, I have a ASP.NET MVC application with URLs that look like the following:

http://example.com/Customer/List
http://example.com/Customer/List/Page/2
http://example.com/Customer/List
http://example.com/Customer/View/8372
http://example.com/Customer/Search/foo/Page/5

这些 URL 是通过 Global.asax.cs

These URLs are achieved with following routes in Global.asax.cs

routes.MapRoute(
    "CustomerSearch"
    , "Customer/Search/{query}/Page/{page}"
    , new { controller = "Customer", action = "Search" }
);

routes.MapRoute(
    "CustomerGeneric"
    , "Customer/{action}/{id}/Page/{page}"
    , new { controller = "Customer" }
);

//-- Default Route
routes.MapRoute(
    "Default",
    "{controller}/{action}/{id}",
    new { controller = "Customer", action = "Index", id = "" }
);

这些都进行得很顺利，直到一个新的需求出现并且想要从 URL 中删除关键字客户"，使 URL 看起来像:

These all have gone well until a new requirement arrived and wants to drop keyword 'Customer' off the URL, to make the URLs look like:

http://example.com/List
http://example.com/List/Page/2
http://example.com/List
http://example.com/View/8372
http://example.com/Search/foo/Page/5

更正示例链接，感谢@haacked.

corrected example links, thanks to @haacked.

我尝试添加新的 MapRoutes 以仅采用 {action} 并将默认控制器设置为 Customer.例如/

I tried to add new MapRoutes to take {action} only and have default controller set to Customer. eg/

routes.MapRoute(
    "CustomerFoo"
    , "{action}"
    , new { controller = "Customer", action = "Index" }
);

这似乎有效，但是现在所有由 Html.ActionLink() 生成的链接都很奇怪并且不再对 URL 友好.

This seems to work, however now all links generated by Html.ActionLink() are weird and no longer URL friendly.

那么，这可以实现吗?我的方向是否正确?

So, is this achievable? Am I approaching in the right direction?

推荐答案

不要将诸如 "{action}/{id}" 之类的规则与 "{controller}/{action}/{id}" ... 特别是当后面的 id 有一个默认值 ie 是可选的.

don't mix a rule like: "{action}/{id}" with one that's "{controller}/{action}/{id}" ... specially when id in the later has a default value i.e. is optional.

在这种情况下，您没有任何东西可以让路由知道使用哪个是正确的.

In that case you have nothing that allows routing to know which one is the right one to use.

如果这是您需要的解决方法，那就是添加约束(请参阅 this) 到前面的动作到一组值即列表、视图.当然，对于这些类型的规则，您不能拥有与操作名称相同的控制器.

A workaround, if that's what you need, would be to add a constrain (see this) to the action in the earlier to a set of values i.e. List, View. Of course that with these types of rules, you can't have a controller with the same name of an action.

还请记住，如果您指定默认操作 &"{action}/{id}" 规则中的 id，当你点击你网站的路由时会用到.

Also remember that if you specify a default action & id in the "{action}/{id}" rule, that will be used when you hit the route of your site.
