对于同一HttpVerb多个动作 [英] Multiple actions for the same HttpVerb

问题描述

我有一个Web API控制器执行以下操作：

I have a Web API controller with the following actions:

    [HttpPut]
    public string Put(int id, JObject data)

    [HttpPut, ActionName("Lock")]
    public bool Lock(int id)

    [HttpPut, ActionName("Unlock")]
    public bool Unlock(int id)

和以下途径映射：

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

当我提出以下要求一切正常：

When I make the following requests everything works as expected:

PUT /api/items/Lock/5
PUT /api/items/Unlock/5

但是，当我试图做一个请求：

But when I attempt to make a request to:

PUT /api/items/5

我得到了以下异常：

I get the following exception:

Multiple actions were found that match the request:
    Put(int id, JObject data)
    Lock(int id)
    Unlock(int id)

我尝试添加一个空的动作名称为缺省路由，而是没有帮助：

I tried adding an empty action name to the default route but that did not help:

[HttpPut, ActionName("")]
public string Put(int id, JObject data)

任何想法如何，我可以用自定义动作的名称结合REST风格的默认路由？

Any ideas how I can combine default RESTful routing with custom action names?

编辑：路由机制不是由控制器的选择困惑。它是由的选择困惑的的动作的一个控制器上。我需要的是指定的任何操作时相匹配的默认操作。希望澄清的事情。

The routing mechanism is not confused by the choice of controller. It is confused by the choice of action on a single controller. What I need is to match the default action when no action is specified. Hope that clarifies things.

推荐答案

的帮助下吉斯卡尔Biamby ，我发现其中我指出了正确的方向这个答案。最后，要解决这个特定的问题，我就是这么做的：

With the help of Giscard Biamby, I found this answer which pointed me in the right direction. Eventually, to solve this specific problem, I did it this way:

routes.MapHttpRoute(
    name: "ApiPut", 
    routeTemplate: "api/{controller}/{id}",
    defaults: new { action = "Put" }, 
    constraints: new { httpMethod = new HttpMethodConstraint("Put") }
);
