在点网核心2中按内容类型进行Web api属性路由? [英] Web api attribute routing, by content type, in dot net core 2?

问题描述

我希望能够使用同一URL使用发布的JSON或表单数据.

I'd like to be able to consume either posted JSON or form data at the same URL.

按现状，我会得到:

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://andrewlock.net/model-binding-json-posts-in-asp-net-core/ suggests using different endpoints, but I can't do that in this case.

https://massivescale.com/web-api-routing-by -content-type/提出了一种用于asp.net的方法，例如:

https://massivescale.com/web-api-routing-by-content-type/ suggests a way to do it for asp.net, for example:

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

或

[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

but in .net core, we don't have System.Web.Http.Routing. Maybe it can be ported to use Microsoft.AspNetCore.Mvc.Routing... but is there something to replace IHttpRouteConstraint

我的问题:.net核心mvc中已经内置了这样的东西吗?

My question: is something like this already built into .net core mvc?

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

For example, in Java's JAX-RS, there is @Consumes("application/json")

推荐答案

我是通过Consumes属性完成此操作的:

I accomplished this by the Consumes attribute:

http://example.com/payment/callback -接受x-www-form-urlencoded

http://example.com/payment/callback - Accepts x-www-form-urlencoded.

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

    }

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

http://example.com/payment/callback - Same url but accepts application/json.

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

    }
