MVC-默认控制器

Question

I am creating a site where I would like to have dynamically added pages. Because of this, I would like to have a simpler URL. What I am aiming for is a URL like the following:

http://www.mysite.com/my-page-url

Rather than a URL like the following:

http://www.mysite.com/pageController/my-page-url

MVC URLs tend to work like this: |url|/|controller|/|action|/|params|

What I would like to do is have: |url|/|params|

For the above URL, if the values of params does not equal the name of a controller, then I would like to pass those params to PageContoller.ProcessDynamicPage.

Depending on what your default params are, you could create a route constraint

    routes.MapRoute(
        "Default",
        "{Param1}",
        new { controller = "ProcessDynamicPage", action = "YourAction" },
        new {Param1= @"\d+" }
    );

This would work if your parameter is an integer.

If your default params are strings or something and you can't create a regex, or something that can't implement IRouteConstraint your best bet it to create a matching action for each of your controllers that way when it falls through the default you've already attempted to do the matching.

routes.MapRoute(
    "YourController",
    "YourController\{Param1}",
    new { controller = "YourController", action = "YourAction" }
   }
);

routes.MapRoute(
    "YourController2",
    "YourController2\{Param1}",
    new { controller = "YourController2", action = "YourAction" }
     }
);

routes.MapRoute(
    "Default",
    "{Param1}",
    new { controller = "ProcessDynamicPage", action = "YourAction" }          
);

If you have a lot of controllers, you should probably really look into how to create the constraint for what you're expecting.

Using MVC's default routing scheme, http://www.mysite.com/my-page-url will go to the Index action in my-page-url controller. If you want to set the default controller and action, you can do so in your Global.asax.cs file it to something like:

routes.MapRoute(
    "Default",                                              // Route name
    "{action}/{pageName}",                           // URL with parameters
    new { controller = "PageContoller", action = "ProcessDynamicPage", pageName = "" }  // Parameter defaults
);

Update

If you need to support additional routes you can create them using the kind of approach that Mark Oreta has suggested. Have a look at Scott Gu's blog and this tutorial .

In IIS 7 you need to look at Handler Mappings. You can specify a particular extension, eg *.action, to be handled by your default controller. I'm a bit rusty now, but I think it was basically the same idea in IIS 6. In my web.config file for my .Net 2.0 application I have the following section inside the system.webServer tag:

    <system.webServer>
        <handlers>
            <add name="defaultAction" path="*.action"   
                verb="*" 
                type="SumikinIntercom.Web.Controller.Controller,SumikinIntercom.Web.Controller" 
                resourceType="Unspecified" requireAccess="None" allowPathInfo="true" />
        </handlers>

So any URL with the extension .action is handled by my default Controller class. Notice the awkward syntax. I had to specify the fully qualified class name (including the assembly name) followed by a comma then the fully qualified assembly name.

There may be irritating changes of syntax for more up-to-date versions of .Net so watch out for those.
