尽管URL路由的帖子多如牛毛，我还没有就这一问题达成启示。

我有一个MVC应用程序工作正常，但我想获得幻想，并做一些URL重写，使其更容易在我的用户。

缺省路由是平时的一个微小的变化：

routes.MapRoute（      默认，      {控制器} / {行动} / {查询}，      新{控制器=SomeController，行动=索引，查询=}）;

我想要做的是重新路由的网址 mysite/12345 到SomeController的详细行动12345查询。我想这样的：

routes.MapRoute（      DirectToDetails      {查询}，      新{控制器=SomeController，行动=详细信息查询=}）;routes.MapRoute（      默认，      {控制器} / {行动} / {查询}，      新{控制器=SomeController，行动=索引，查询=}）;

但最终掩盖 mysite/ 以及它去SomeController /细节，而不是SomeController的/索引。

编辑：

@乔恩每次的意见，我删除了查询=的匿名对象：

routes.MapRoute（      DirectToDetails      {查询}，      新{控制器=SomeController，行动=详细信息}）;

...其中涉及的问题尽可能去;现在，当我在查看/ SomeView /索引提交表单（即提交上述SomeController /详细信息）我得到一个资源无法找到的错误。

下面的形式声明：

＆LT;％使用（Html.BeginForm（              细节，              SomeController              FormMethod.Post，              新{ID =SearchForm}））{％GT;    ＆LT;％Html.RenderPartial（SearchForm模型）; ％GT;    ＆LT;％= Html.ValidationMessageFor（型号=＆GT; model.Query）％GT;＆LT;％}％GT;

解决方案

删除查询=（显然这不是可选正是因为这个问题你遇到 - 没必要把它的第三个参数，如果没有合理的缺省值），并使用图路线的重载需要4个参数与路由约束：

routes.MapRoute（  DirectToDetails  {查询}，  新{控制器=SomeController，行动=详细信息}，  新{查询= @\\ D +}）;

显然，你将需要调整正则表达式，如果它不是一个整数...

在回答您的编辑...确保你已经删除从短路线查询默认的 - 你已经发布的默认一个人也没有。也建议你仔细检查的形式，并确保它张贴值查询（也许设置岗位操作方法一个破发点，并确保查询参数被正确绑定？）。

Despite the plethora of URL routing posts, I have yet to reach enlightenment on the subject.

I have an MVC app that works fine, but I want to get fancy and do some URL rewriting to make it easier on my users.

The default route is a slight variation on the usual:

routes.MapRoute( "Default", "{controller}/{action}/{query}", new{ controller = "SomeController", action="Index", query = "" });

What I want to do is re-route the URL mysite/12345 to the Details action of SomeController with the 12345 query. I tried this:

routes.MapRoute( "DirectToDetails", "{query}", new{ controller = "SomeController", action="Details" query="" }); routes.MapRoute( "Default", "{controller}/{action}/{query}", new{ controller = "SomeController", action="Index", query = "" });

but that ends up obscuring mysite/ and it goes to SomeController/Details instead of SomeController/Index.

EDIT:

per the advice of @Jon I removed the query = "" in the anonymous object:

routes.MapRoute( "DirectToDetails", "{query}", new{ controller = "SomeController", action="Details" });

... which addressed the question as far as it went; now when I submit the form at Views/SomeView/Index (that submits to the aforementioned SomeController/Details) I get a "resource cannot be found" error.

Here is the form declaration:

<% using (Html.BeginForm( "Details", "SomeController", FormMethod.Post, new { id = "SearchForm" })) { %> <% Html.RenderPartial("SearchForm", Model); %> <%= Html.ValidationMessageFor(model => model.Query) %> <% } %>

解决方案

Remove the query = "" (obviously it's not optional exactly because of the problem you're having - no need to put it in the 3rd argument if there's no sensible default) and use the overload of MapRoute that takes a 4th parameter with route constraints:

routes.MapRoute( "DirectToDetails", "{query}", new { controller = "SomeController", action="Details" }, new { query = @"\d+" });

Obviously you will need to adjust the regex if it's not an integer...

In response to your edit...make sure that you've removed the default for query from the "short" route - you've posted the default one there. Also suggest you double check the form and make sure it's posting a value for query (maybe set a break point on the post action method and make sure the query parameter is being bound correctly?).
