asp.net-core-mvc - 在点网核心2中按内容类型进行Web api属性路由？

Question

我希望能够使用同一URL使用发布的JSON或表单数据。

就目前情况而言，我得到:

fail: Microsoft.AspNetCore.Mvc.Internal.ActionSelector[1]
      Request matched multiple actions resulting in ambiguity. Matching actions: 
:
fail: Microsoft.AspNetCore.Server.Kestrel[13]
      Connection id "0HLDLB0LJCPJ4", Request id "0HLDLB0LJCPJ4:00000001": An unhandled exception was thrown by the application.
Microsoft.AspNetCore.Mvc.Internal.AmbiguousActionException: Multiple actions matched. The following actions matched route data and had all constraints satisfied:

https://andrewlock.net/model-binding-json-posts-in-asp-net-core/建议使用不同的端点，但是在这种情况下我不能这样做。

https://massivescale.com/web-api-routing-by-content-type/建议为asp.net执行此操作的方法，例如:

[ContentTypeRoute("api/test/bytype", "application/json")]

或者

[ContentTypeRoute("api/test/bytype", "application/x-www-form-urlencoded")]

但是在.net核心中，我们没有System.Web.Http.Routing。也许可以将其移植为使用Microsoft.AspNetCore.Mvc.Routing ...，但是是否可以替换IHttpRouteConstraint

我的问题:.net核心mvc中已经内置了这样的东西吗？

例如，在Java的JAX-RS中，有@Consumes(“application/json”)

Answer 1

我是通过Consumes属性完成此操作的:
http://example.com/payment/callback-接受x-www-form-urlencoded。

[HttpPost]
[Route("callback")]
[Consumes("application/x-www-form-urlencoded")]
public ActionResult Post([FromForm] string value)
{

}

http://example.com/payment/callback-相同的URL，但接受application/json。

[HttpPost]
[Route("callback")]
[Consumes("application/json")]
public ActionResult Post([FromBody] JObject value)
{

}
