推荐答案

更新 ASP.NET Core 2.1

自 ASP.NET Core 2.1 起，可使用一组新类型来创建 Web API 控制器.您可以使用 [ApiController] 属性注释您的控制器，该属性启用一些新功能，例如自动模型状态验证和绑定源参数推断.有关更多信息，请参阅文档:https://docs.microsoft.com/en-us/aspnet/core/web-api/index?view=aspnetcore-2.1#annotate-class-with-apicontrollerattribute.

Since ASP.NET Core 2.1 a new set of types is available to create Web API controllers. You can annotate your controllers with the [ApiController] attribute which enables a few new features such as automatic model state validation and binding source parameter inference. See the docs for more information: https://docs.microsoft.com/en-us/aspnet/core/web-api/index?view=aspnetcore-2.1#annotate-class-with-apicontrollerattribute.

确实不再有特定的 ApiController 类，因为 MVC 和 WebAPI 已合并到 ASP.NET Core 中.但是，MVC 的 Controller 类引入了许多在开发 Web API 时可能不需要的功能，例如视图和模型绑定.

There is indeed no particular ApiController class anymore since MVC and WebAPI have been merged in ASP.NET Core. However, the Controller class of MVC brings in a bunch of features you probably won't need when developing just a Web API, such as a views and model binding.

如果您想要不同的东西，您有两个选择:

You've got two options if you want something different:

使用 Microsoft.AspNetCore.Mvc.Core 包.

Use the ControllerBase class in the Microsoft.AspNetCore.Mvc.Core package.

或

创建您的 ApiController 基类.这里的关键是添加 [ActionContext] 属性，该属性将当前的 ActionContext 实例注入到属性中:

Create your ApiController base class. The key here is to add the [ActionContext] attribute which injects the current ActionContext instance into the property:

[Controller]
public abstract class ApiController
{
    [ActionContext]
    public ActionContext ActionContext { get; set; }
}

此外，将 [Controller] 属性添加到该类，以将其标记为 MVC 控制器发现的控制器.

Also, add the [Controller] attribute to the class to mark it as a controller for the MVC controller discovery.
