IHttpActionResult - new way of creating responses in ASP

Overall, IHttpActionResult is extremely useful interface for Web API developers. It is something that was very needed - as an alternative to forcing developers to deal with formatters. By declaring your own custom results, you can streamline lots of processes and easily achieve the desired output of your actions IHttpActionResult Interface. 10/28/2015; 2 minutes to read; In this article Defines a command that asynchronously creates an HttpResponseMessage. Namespace: System.Web.Http Assembly: System.Web.Http (in System.Web.Http.dll) Syntax public interface IHttpActionResult public interface class IHttpActionResult type IHttpActionResult = interface en IHttpActionResult (new in Web API 2.0) Some other data type. Now in today's article we will see the third point with an example. To use IHttpResult in your application, you must include System.WebHttp and provide a reference of the system.Web.Http assembly

The IHttpActionResult was introduced by WebAPI 2 which is a kind of wrap of HttpResponseMessage. It contains the ExecuteAsync() method to create an HttpResponseMessage . It simplifies unit testing of your controller ASP.Net Web API 2 IHttpActionResult: As we talked before ASP.Net Web API 2 has introduced new simplified interface named IHttpActionResult, this interface acts like a factory for HttpResponseMessage, it comes with custom built in responses such as (Ok, BadRequest, NotFound, Unauthorized, Exception, Conflict, Redirect) IHttpActionResult interface; Make the following changes: Change ApiController to ControllerBase. Add using Microsoft.AspNetCore.Mvc; to resolve the ControllerBase reference. Delete using System.Web.Http;. Change the GetProduct action's return type from IHttpActionResult to ActionResult<Product>. Simplify the GetProduct action's return statement to the following In ASP.NET Web API 2, the IHttpActionResult offers a lot of value in simplifying controller code and I'm reluctant to stop using it, but I've hit a problem. I need to set an ETag on an outgoing response, and I cannot find any property which gives me access to the response's headers. At the moment I'm using the Ok<T> (T content) helper method from.

To fix this, you can modify the controller method signiture to return IHttpActionResult and pass the returned data to the Ok class (which is of type OkNegotiatedContentResult, which returns as HttpStatusCode.OK if all was well). The Controller class should remain inherited from ApiController public class TestController : ApiController { public IHttpActionResult Get() { return this.NotFound(These are not the droids you're looking for.); If you used a custom controller base class (instead of directly inheriting from ApiController), you could also eliminate the this IHttpActionResult. Ihttpactionresultインターフェイスは、Web API 2 で導入されました。 基本的には、 HttpResponseMessageファクトリを定義します。 Ihttpactionresultインターフェイスを使用すると、次のような利点があります。 コントローラーの単体テストを簡略化します

IHttpActionResult: in this case the Web API runtime converts the return value to an Http response message object (an HttpResponseMessage instance is created asynchronously) internally and returns it WebApi controller actions can return a variety of response types: HttpResponseMessage, IHttpActionResult, CLR objects and then the Task based variety of each for async actions. But which one is best? And how do we unit test them? Lets look at each in turn and examine why IHttpActionResult is usually the right choice Web API 2 introduced the new interface IHttpActionResult to return back REST responses, where Web API 1 was using the class HttpResponseMessage to represent HTTP response, and HTTPResponseException to represent HTTP response error. IHttpActionResult allows developers to enhance their Web API 1 code to be : More testable. More reusable Note: IHttpActionResult is introduced in ASP.NET Web API 2 and the remaining are introduced in earlier versions of Web API. HttpResponseMessage If the return type of the action method is one of the Web API's action results, then the API converts the return value to a HTTP Response Message Importance of Web API documentation. Web API documentation is really very helpful when two different team (Back end and Front end) are working on project and not sitting together so in that scenario you will send your API information through mail or call
