如何使{控制器} / {ID} / {}行动中MVC4工作？ [英] How to make {controller}/{id}/{action} work in MVC4?

问题描述

我用尽了一切办法，但貌似我只是没有得到它。我WebApiConfig.cs看起来是这样的：

I've tried everything but looks like I'm just not getting it at all. My WebApiConfig.cs looks like this:

config.Routes.MapHttpRoute(
    "Default",
    "api/{controller}/{id}",
    new { id = RouteParameter.Optional });

config.Routes.MapHttpRoute(
    "AccountVerification",
    "api/{controller}/{id}/{action}",
    null,
    new { controller = "Account" });

和我的控制器是这样的：

And my controller looks like this:

public class AccountController : ApiController {
    public HttpResponseMessage GetByKey(Guid accountID) {
        ...
    }

    [HttpGet]
    [ActionName("Verify")]
    public HttpResponseMessage VerifyAccount(Guid accountID) {
        ...
    }
}

这些方法应该得到一击与以下网址：

These methods should get a hit with the following URLs:

GET /api/account                                        - WORKS
GET /api/account/00000000-0000-0000-000000000001        - WORKS
GET /api/account/00000000-0000-0000-000000000001/verify - DOESNT WORK

我已经尝试了很多东西;我肯定在这里做得不对......请帮助。

I've tried a lot of things; I am definitely doing something wrong here...please help.

推荐答案

首先，如果你想用假GUID来测试，以及具有可选的Guid参数，它们必须是空的参数的（假的GUID将被反序列为空）

First, if you want to test with fake Guids, as well as having optional Guid parameters, they must be Nullable parameters (fake guids will be deserialized as null) :

public class AccountController : ApiController
{
    public HttpResponseMessage GetByKey(Guid? accountID)
    {
        throw new Exception("GetByKey " + (accountID.HasValue ? accountID.ToString() : "NULL"));
    }

    [System.Web.Http.HttpGet]
    [System.Web.Http.ActionName("Verify")]
    public HttpResponseMessage VerifyAccount(Guid? accountID)
    {
        throw new Exception("VerifyAccount "+(accountID.HasValue?accountID.ToString():"NULL"));
    }
}

那么，你的映射应该：

then, your mapping should :

• 先用最具体的路线


• 使用正确的参数名称



• 使用正确的默认设置行为

• use the most specific route first
• use the correct parameters names

• use the correct defaults for actions

config.Routes.MapHttpRoute(
    "AccountVerification",
    "api/{controller}/{accountID}/{action}"
    );


config.Routes.MapHttpRoute(
    "Default",
    "api/{controller}/{accountID}",
    defaults: new { Controller="Account", action = "GetByKey", accountID = RouteParameter.Optional }
    );
