WebApi路由：同时api/{controller}/{id}和api/{controller}/{action}

Question

我有默认的 webapi 路由配置：

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

我想支持以下场景：

//api/mycontroller
public IQueryable<MyDTO> Get();

//api/mycontroller/{id} where id can be anything except "customaction1" and "customaction2"
public HttpResponseMessage Get(string id);

//api/mycontroller/customaction
[HttpPost]
public void CustomAction1([FromBody] string data);
[HttpPost]
public void CustomAction2([FromBody] string data);

我尝试将[Route("api/mycontroller/customaction1")] 应用于CustomAction1 方法，类似于CustomAction2，但得到：

找到多个与请求匹配的操作： MyProject.WebApiService.MyController 类型上的 CustomAction1 MyProject.WebApiService.MyController 类型上的 CustomAction2

确保您在默认配置中配置了属性路由

//....
config.MapHttpAttributeRoutes()

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

如果你想用 out 属性路由做同样的事情，那么你需要显式配置路由

//This one constrains id to be an int
config.Routes.MapHttpRoute(
    name: "DefaultApi",
    routeTemplate: "api/{controller}/{id}",
    defaults: new { action="Get", id = RouteParameter.Optional },
    constraints : new { id = @"\d" }
);
//This one should catch the routes with actions included
config.Routes.MapHttpRoute(
    name: "ActionRoutes",
    routeTemplate: "api/{controller}/{action}"
);
