ASP的无限URL参数。净MVC路线

I need an implementation where I can get infinite parameters on my ASP.NET Controller. It will be better if I give you an example :

我需要一个实现，在这个实现中，我可以在ASP中获得无限的参数。网络控制器。如果我给你举个例子会更好:

Let's assume that I will have following urls :

假设我有以下url:

example.com/tag/poo/bar/poobar
example.com/tag/poo/bar/poobar/poo2/poo4
example.com/tag/poo/bar/poobar/poo89

As you can see, it will get infinite number of tags after example.com/tag/ and slash will be a delimiter here.

正如您所看到的，在example.com/tag/和slash之后，它将获得无限数量的标签。

On the controller I would like to do this :

在控制器上，我想这样做:

foreach(string item in paramaters) { 

    //this is one of the url paramaters
    string poo = item;

}

Is there any known way to achieve this? How can I get reach the values from controller? With Dictionary<string, string> or List<string>?

有什么已知的方法可以做到这一点吗?如何从控制器获取值?使用字典或List ? ,>

NOTE :

注意:

The question is not well explained IMO but I tried my best to fit it. in. Feel free to tweak it

这个问题在我看来没有很好的解释，但我尽力去适应它。在。请随意调整

Like this:

是这样的:

routes.MapRoute("Name", "tag/{*tags}", new { controller = ..., action = ... });

ActionResult MyAction(string tags) {
    foreach(string tag in tags.Split("/")) {
        ...
    }
}

The catch all will give you the raw string. If you want a more elegant way to handle the data, you could always use a custom route handler.

所有的捕获都将给你原始的字符串。如果您想要一种更优雅的方法来处理数据，您可以始终使用自定义路由处理程序。

public class AllPathRouteHandler : MvcRouteHandler
{
    private readonly string key;

    public AllPathRouteHandler(string key)
    {
        this.key = key;
    }

    protected override IHttpHandler GetHttpHandler(RequestContext requestContext)
    {
        var allPaths = requestContext.RouteData.Values[key] as string;
        if (!string.IsNullOrEmpty(allPaths))
        {
            requestContext.RouteData.Values[key] = allPaths.Split('/');
        }
        return base.GetHttpHandler(requestContext);
    }
}

注册路由处理程序。

routes.Add(new Route("tag/{*tags}",
        new RouteValueDictionary(
                new
                {
                    controller = "Tag",
                    action = "Index",
                }),
        new AllPathRouteHandler("tags")));

Get the tags as a array in the controller.

在控制器中以数组的形式获取标记。

public ActionResult Index(string[] tags)
{
    // do something with tags
    return View();
}

#3

That's called catch-all:

这叫做全方位:

tag/{*tags}

Just in case anyone is coming to this with MVC in .NET 4.0, you need to be careful where you define your routes. I was happily going to global.asax and adding routes as suggested in these answers (and in other tutorials) and getting nowhere. My routes all just defaulted to {controller}/{action}/{id}. Adding further segments to the URL gave me a 404 error. Then I discovered the RouteConfig.cs file in the App_Start folder. It turns out this file is called by global.asax in the Application_Start() method. So, in .NET 4.0, make sure you add your custom routes there. This article covers it beautifully.

为了防止任何人在。net 4.0中使用MVC时遇到这种情况，您需要小心地定义路由。我很高兴去环球旅行。asax和添加在这些答案(以及其他教程)中建议的路线，并没有得到任何结果。我的路由都默认为{controller}/{action}/{id}。向URL添加更多的段给了我一个404错误。然后我发现了RouteConfig。在App_Start文件夹中的cs文件。这个文件被全局调用。asax在Application_Start()方法中。所以，在。net 4.0中，一定要添加自定义路由。这篇文章写得很好。
