Question

对于默认的get，post，put和delete方法，我添加了一些getter，其中一些是参数。

public class AController
{   
    // GET api/A
    [HttpGet]
    public HttpResponseMessage GetAs() { ... }

    // GET api/A/5
    [HttpGet]
    public HttpResponseMessage GetA(int id) { ... }

    // GET api/A/GetThis
    [HttpGet]
    public HttpResponseMessage GetThis() { ... }

    // GET api/A/GetThat
    [HttpGet]
    public HttpResponseMessage GetThat() { ... }

    // GET api/A/GetMoreInfoAbout/5
    [HttpGet]
    public HttpResponseMessage GetMoreInfoAbout(int id) { ... }

    // PUT api/A
    [HttpPut]
    public HttpResponseMessage PutA(int id, A a) { ... }

    // POST api/A
    [HttpPost]
    public HttpResponseMessage PostA(A a) { ... }

    // DELETA api/A
    [HttpDelete]
    public HttpResponseMessage DeleteA(int id) { ... }
}

我到目前为止所做的是为每个方法指定一个新的路由，因此我的WebApiConfig.cs被炸毁了，并且每个新的控制器和方法越来越不透明。

我尝试了这种更通用的路由：

config.Routes.MapHttpRoute(
    name: "ApiById",
    routeTemplate: "api/{controller}/{id}",
    defaults: new { id = RouteParameter.Optional },
    constraints: new { id = @"^[0-9]+$" }
);

config.Routes.MapHttpRoute(
    name: "ApiByActionId",
    routeTemplate: "api/{controller}/{action}/{id}",
    defaults: null,
    constraints: new { id = @"^[0-9]+$" }
);

config.Routes.MapHttpRoute(
    name: "ApiByAction",
    routeTemplate: "api/{controller}/{action}",
    defaults: null
);

/* Default route */
config.Routes.MapHttpRoute(
    name: "DefaultApi",
    routeTemplate: "api/{controller}/{id}",
    defaults: new { id = RouteParameter.Optional }
);

我必须在何处设置默认设置，GET api/A与GetAs()匹配，POST api/A与PostA(A a)匹配？
与GET api/A/5相同。

嗯，这不是我实际想要的解决方案，但它仍然比手动为每个控制器添加一堆路由更通用。

它的作用基本上是为每个控制器添加两条路由。这些路由模板涵盖了对api / [ControllerName] / {id}和api / [ControllerName]的请求，并将它们委托给相应的控制器操作。

foreach (Type t in GetTypesInNamespace(Assembly.GetExecutingAssembly(), "MyProject.Controllers")) {
    if (typeof(ApiController).IsAssignableFrom(t)) { // Make sure that this controller class is deriving from api controller
        string controllerName = t.Name.Substring(0, t.Name.LastIndexOf("Controller"));  // Remove Controller postfix from name
        config.Routes.MapHttpRoute(
            name: "ApiGet" + controllerName,
            routeTemplate: "api/" + controllerName + "/{id}",
            defaults: new { controller = controllerName, action = "Get" + controllerName },
            constraints: new { id = @"^[0-9]+$", httpMethod = new HttpMethodConstraint(HttpMethod.Get) }
        );

        config.Routes.MapHttpRoute(
            name: "ApiGet" + controllerName + "s",
            routeTemplate: "api/" + controllerName + "/{id}",
            defaults: new { controller = controllerName, id = RouteParameter.Optional, action = "Get" + controllerName + "s" },
            constraints: new { httpMethod = new HttpMethodConstraint(HttpMethod.Get) }
        );
    }
}

我相信你可以在这里使用属性路由。请参阅以下链接以获取更多信息： http://www.asp.net/web-api/overview/web-api-routing-and-actions/attribute-routing-in-web-api-2
