问题描述

场景:在 .net 核心控制器上实现标准 REST API/GET 方法.

Scenario: implementing a standard REST API / GET method on a .net core controller.

文档指出 OkObjectResult是一个状态为 200 的 ObjectResult.这可通过从 ControllerBase 继承的 Ok(myResult) 方法获得.我认为这是一种方便的方法.

The documentation states that OkObjectResult is an ObjectResult with status 200. This is available through the Ok(myResult) method inherited from ControllerBase. I assume this is a convenience method.

但是，教程没有使用这种方法 - 它改为返回 new ObjectResult(myResult) ，默认状态为 200.

However, the tutorial is not using this approach - it instead returns new ObjectResult(myResult) which will default to status 200.

这两种方法有什么区别吗?

Is there any difference between these two approaches?

推荐答案

技术上这两种方法没有区别.

如果你想看OkObjectResult 那么你会看到 OkObjectResult 是一个 ObjectResult 设置200状态码，这是默认的ObjectResult 已经.

If you want to look at the code of OkObjectResult then you will see that the OkObjectResult is an ObjectResult that sets the 200 status code, which is the default of ObjectResult already.

对我而言，唯一的区别是代码的可读性以及您自己或您的团队的偏好.这完全取决于命名以及您要强调的意图.

The only difference for me is readability in code and your own or your team preferences. It is all about naming and what intention you want to stress.

 return Ok(myResult);                  // gives emphasis on status, my personal favorite

 return new OkObjectResult(myResult);  // for me a little bit verbose and the same
                                       // effect as Ok; but states we return an Object

 return new ObjectResult(myResult);    // gives emphasis of the content that is returned
