如何分隔路径相同但功能不同的路线? [英] How do I separate routes that have the same path but do different things?

问题描述

以下路由 Page/View/Id 将转到页面控制器"中的 View 方法.我还想要以下路线:

The following route Page/View/Id would go to the View Method in the Page Controller. I'd also like the following route:

/{page-title}

转到相同的方法.这样一来，我可以拥有类似以下的网址:

to go to the same method. That's so I could have URLs like the following:

http://www.mysite.com/This-Is-a-Page

考虑 This-Is-a-Page 也可能是控制器，我该如何配置呢?

How do I configure this, considering This-Is-a-Page might be a controller also?

推荐答案

如果您的控制器"路由和页面"路由(请参见下文)都使用相同的/something ，那么您必须执行以下规则:

If both your "controller" routes and "page" routes (see below) use the same /something, then you're going to have to implement the following rules:

在路线顶部:

route. MapRoute(
    "ControllerRoute"
    "{controller}",
    new { controller = "Home", action = "Index" }
    new { controller = GetControllerNameRegex() }
);

route.MapRoute(
    "PageRoute",
    "{pageSlug}"
    new { controller = "Page", action = "ShowPage" }
);

• 任何页面的名称都不能与使用中的任何控制器相匹配.
• 或者没有控制器具有与正在使用的任何页面相匹配的名称.

因为您无法真正通过编程方式完成后者，但

Since you can't really do the latter programmatically, but you can do the former programmatically, you can add a custom constraint to your controller routes, so that it will only hit if you happen to type the name of a controller:

private static string GetControllerNameRegex()
{
    var controllerNamesRegex = new StringBuilder();
    List<string> controllers = GetControllerNames();
    controllers.ForEach(s =>
            controllerNamesRegex.AppendFormat("{0}|", s));
    return controllerNamesRegex.ToString().TrimEnd('|');
}

private static List<Type> GetSubClasses<T>()
{
    return Assembly.GetCallingAssembly().GetTypes().Where(type => 
           type.IsSubclassOf(typeof(T))).ToList();
}

public List<string> GetControllerNames()
{
    List<string> controllerNames = new List<string>();
    GetSubClasses<Controller>().ForEach(type => controllerNames.Add(type.Name));
    return controllerNames;
}

注意事项:最好的方法是确保没有以控制器命名的页面，并且可以使用上述代码在运行时强制执行该操作.

NB: Best course would be to make sure not to have any pages named after your controller, and you could use the above code to enforce that at runtime.
