c# - WebAPI 路由 : Combining Attributes and HttpConfiguration settings

Question

我正在尝试为同一条路线使用 GET 和 POST:

我已经注册了以下内容:

  config.MapHttpAttributeRoutes();

  config.Routes.MapHttpRoute(
                name: "MyGetMethod",
                routeTemplate: "api/v1/users/{user}",
                defaults: new
                              {
                                  controller = "Users",
                                  action = "MyGetMethod"
                              },
                constraints: null,
                handler: HttpClientFactory.CreatePipeline(
                    new HttpControllerDispatcher(config),
                    routeHandlerFactory.Create()));

  config.Routes.MapHttpRoute(
                name: "MySetMethod",
                routeTemplate: "api/v1/users/{user}",
                defaults: new
                              {
                                  controller = "Users",
                                  action = "MySetMethod"
                              },
                constraints: null,
                handler: HttpClientFactory.CreatePipeline(
                    new HttpControllerDispatcher(config),
                    routeHandlerFactory.Create()));

我的 UsersController.cs 包含:

 [HttpPost]
    public HttpResponseMessage MySetMethod(string user)
    {
        return new HttpResponseMessage(HttpStatusCode.NotImplemented);
    }


 [HttpGet]
    public HttpResponseMessage MyGetMethod(string user)
    {
        return new HttpResponseMessage(HttpStatusCode.NotImplemented);
    }

这行不通。 GET 工作正常，但是当我使用 POST 时，WebAPI 仍然重定向到 GET 方法，我得到错误:

"Message": "The requested resource does not support http method 'POST'."

如果我注释掉 GET 方法的注册，那么 POST 就可以正常工作。

是不是因为我在 Controller 方法上使用属性 [HttpPost]、[HttpGet] 的组合，而不是将它们标记为 constraints?

我怎样才能在同一条路线上有 GET 和 POST？

Answer 1

如果你用这个就可以了

config.MapHttpAttributeRoutes();

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