asp.net mvc的路由：如何使用默认的动作，但非默认参数？

问题描述

我重写的问题，因为答案为止告诉我，我还没有定义它不够好。我会离开原来的问题下面的参考。

I'm rewriting the question, as the answers so far show me that I have not defined it good enough. I'll leave the original question for reference below.

当您设置路由，您可以指定不同的URL /路由部分违约。让我们考虑的例子，VS向导生成：

When you set up your routing you can specify defaults for different url/route parts. Let's consider example that VS wizard generates:

        routes.MapRoute(
            "Default", // Route name
            "{controller}/{action}/{id}", // URL with parameters
            new { controller = "DefaultPage", action = "Index", id = UrlParameter.Optional } // Parameter defaults

在本实施例中，如果未指定控制器，DefaultPageController将被使用，将被使用，如果不是指定的动作是索引的动作。
该网址通常如下：的http：// mysite的/ myController的/ MyAction

In this example if controller is not specified, DefaultPageController will be used and if action is not specified "Index" action will be used.The urls will generally look like: http://mysite/MyController/MyAction.

如果没有在网址没有动作是这样的：的http：// mysite的/ myController的则将使用索引操作

If there is no action in Url like this: http://mysite/MyController then the index action will be used.

现在让我们假设我有我的控制器指数AnotherAction两个动作。这与它们对应的网址是的http：// mysite的/ myController的和的http：// mysite的/ myController的/ AnotherAction 分别。我的索引行动接受一个参数，ID。所以，如果我需要一个参数传递给我的索引行动，我可以这样做：的http：// mysite的/ myController的/索引/ 123 。请注意，不像在网址的http：// mysite的/ myController的，我必须明确地指定索引操作。我想要做的是能够通过的http：// mysite的/ myController的/ 123 而不是的http：// mysite的/ myController的/索引/ 123 。我不需要指数在这个网址我想MVC引擎承认，当我要求的http：// mysite的/ myController的/ 123 ，即123不操作（因为我还没有定义与此名称的动作），而是一个参数，以我的默认操作索引。我如何设置路由实现这一目标？

Now let's assume I have two actions in my controller Index and AnotherAction. The urls that correspond to them are http://mysite/MyController and http://mysite/MyController/AnotherAction respectively. My "Index" action accepts a parameter, id. So If I need to pass a parameter to my Index action, I can do this: http://mysite/MyController/Index/123. Note, that unlike in URL http://mysite/MyController, I have to specify the Index action explicitly. What I want to do is to be able to pass http://mysite/MyController/123 instead of http://mysite/MyController/Index/123. I do not need "Index" in this URL I want the mvc engine to recognize, that when I ask for http://mysite/MyController/123, that 123 is not an action (because I have not defined an action with this name), but a parameter to my default action "Index". How do I set up routing to achieve this?

下面是问题的原来的措辞。

Below is the original wording of the question.

我有definded这样两种方法控制​​器

I have a controller with two methods definded like this

    public ActionResult Index()
    {
        return View();
    }

    [HttpPost]
    public ActionResult Index(SomeFormData data)
    {
        return View();

    }

这让我来处理URL像的http：//网站/页既当用户浏览到该URL（GET），当他们随后回发的形式（ POST）。

This allows me to process Url like http://website/Page both when the user navigates to this url (GET) and when they subsequently post back the form (POST).

现在，当我处理回发，在某些情况下，我想将浏览器重定向到这个网址：

Now, when I process the post back, in some cases I want to redirect the browser to this url:

http://website/Page/123

其中123是一些整数，我需要一种方法在我的控制器来处理这个网址。

Where 123 is some integer, and I need a method to process this url in my controller.

我如何设置路由，所以这个作品？目前，我有这样的向导生成的默认路由：

How do I set up the routing, so this works? Currently I have "default" routing generated by the wizard like this:

        routes.MapRoute(
            "Default", // Route name
            "{controller}/{action}/{id}", // URL with parameters
            new { controller = "DefaultPage", action = "Index", id = UrlParameter.Optional } // Parameter defaults

我尝试添加这样的另一个控制器方法：

I tried adding another controller method like this:

public ActionResult Index(int id)
{
    return View();
}

但是，这并不工作，因为暧昧动作抛出异常：

But this doesn't work as ambiguous action exception is thrown:

行动索引当前请求
  控制器类型的PageController
  就是下面的暧昧
  操作方法：
  System.Web.Mvc.ActionResult指数（）上
  类型的PageController
  System.Web.Mvc.ActionResult
  在类型的PageController指数（Int32）已

我要补充一点，我也有此控制器中的其他操作。 会工作。

I must add, that I also have other actions in this controller. This would have worked if I didn't.

推荐答案

下面是这可怎么原来决心：

Here is how this can be resoled:

您可以创建一个路由约束，以指示路由引擎，如果你有网址，看起来像一个数字（123）的东西，那么这是默认操作的操作参数，如果你有一些不看起来像一个数字（AnotherAction），那么它的行动。

You can create a route constraint, to indicate to the routing engine, that if you have something in url that looks like a number (123) then this is an action parameter for the default action and if you have something that does not look like a number (AnotherAction) then it's an action.

考虑这code：

routes.MapRoute(
  "MyController", "MyController/{productId}", 
  new {controller="My", action="Index"}, 
  new {productId = @"\d+" });

这个路由定义将只在 HTTP匹配后myController的数值：// mysite的/ myController的/ 123 所以它不会与调用同一个控制器上的另一个动作干扰。

This route definition will only match numeric values after MyController in http://mysite/MyController/123 so it will not interfere with calling another action on the same controller.
