如何使用IHttpActionResult对Created-201响应进行编码

Question

如何使用IHttpActionResult？编写Created-201响应？

IHttpActionResult 只有这些选项

• 好
• 项目清单
• 未找到
• 例外
• 擅自
• 错误的请求
• 冲突重定向
• InvalidModelState

我现在正在做的是下面的代码,但我想使用IHttpActionResult而不是 HttpResponseMessage

 public IHttpActionResult Post(TaskBase model)
        {
           HttpResponseMessage response = Request.CreateResponse(HttpStatusCode.Created, model);
          response.Headers.Add("Id", model.Id.ToString());
          return ResponseMessage(response);
         }

Answer 1

如果您的视图派生自ApiController,您应该能够Created从基类调用该方法来创建这样的响应.

样品:

[Route("")]
public async Task<IHttpActionResult> PostView(Guid taskId, [FromBody]View view)
{
    // ... Code here to save the view

    return Created(new Uri(Url.Link(ViewRouteName, new { taskId = taskId, id = view.Id })), view);
}

Answer 2

在 ASP.NET Core 中，IActionResult可以返回 。这意味着您可以返回ObjectResult带有 201 状态代码的 。

[HttpPost]
public async Task<IActionResult> PostAsync([FromBody] CreateModel createModel)
{
    // Create domain entity and persist
    var entity = await _service.Create(createModel);

    // Return 201
    return new ObjectResult(entity) { StatusCode = StatusCodes.Status201Created };
}

Answer 3

或者，根据 Chris 的建议，您可以使用“ StatusCode ”方法返回 IActionResult，方法如下：

[HttpPost]
public async Task<IActionResult> PostAsync([FromBody] CreateModel createModel)
{
    // Create domain entity and persist
    var entity = await _service.Create(createModel);

    // Return 201
    return StatusCode(StatusCodes.Status201Created, entity);
}

Answer 4

return Content(HttpStatusCode.Created, "Message");

内容返回NegotiatedContentResult.NegotiatedContentResult实现了IHttpActionResult.

类似的问题:如果你想发送带有消息的NotFound.

return Content(HttpStatusCode.NotFound, "Message");

要么:

return Content(HttpStatusCode.Created, Class object);
return Content(HttpStatusCode.NotFound, Class object);
