ASP.net MVC 4 WebApi 中的嵌套资源

本文介绍了ASP.net MVC 4 WebApi 中的嵌套资源的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

在新的 ASP.net MVC 4 WebApi 中，是否有比为每个资源设置特殊路由更好的方法来处理嵌套资源?(类似于此处:ASP.Net MVC 对嵌套资源的支持?- 这是 2009 年发布的).

Is there a better way in the new ASP.net MVC 4 WebApi to handle nested resources than setting up a special route for each one? (similar to here: ASP.Net MVC support for Nested Resources? - this was posted in 2009).

比如我要处理:

/customers/1/products/10/

我见过一些 ApiController 动作的例子，除了 Get()、Post() 等，例如我看到了一个名为 GetOrder() 的操作示例.不过，我找不到任何关于此的文档.这是实现这一目标的方法吗?

I have seen some examples of ApiController actions named other than Get(), Post() etc, for example here I see an example of an action called GetOrder(). I can't find any documentation on this though. Is this a way to achieve this?

推荐答案

抱歉，我已经更新了多次，因为我自己正在寻找解决方案.

Sorry, I have updated this one multiple times as I am myself finding a solution.

似乎有很多方法可以解决这个问题，但目前我发现最有效的方法是:

Seems there is many ways to tackle this one, but the most efficient I have found so far is:

在默认路由下添加:

routes.MapHttpRoute(
    name: "OneLevelNested",
    routeTemplate: "api/{controller}/{customerId}/{action}/{id}",
    defaults: new { id = RouteParameter.Optional }
);

此路由随后将匹配 URL 中的任何控制器操作和匹配的段名称.例如:

This route will then match any controller action and the matching segment name in the URL. For example:

/api/customers/1/orders 将匹配:

/api/customers/1/orders will match:

public IEnumerable<Order> Orders(int customerId)

/api/customers/1/orders/123 将匹配:

/api/customers/1/orders/123 will match:

public Order Orders(int customerId, int id)

/api/customers/1/products 将匹配:

/api/customers/1/products will match:

public IEnumerable<Product> Products(int customerId)

/api/customers/1/products/123 将匹配:

/api/customers/1/products/123 will match:

public Product Products(int customerId, int id)

方法名称必须与路由中指定的 {action} 段匹配.

The method name must match the {action} segment specified in the route.

来自评论

因为RC你需要告诉每个动作哪种动词是可以接受的，即[HttpGet]等

Since the RC you'll need to tell each action which kind of verbs that are acceptable, ie [HttpGet], etc.
