c# - 如何阻止 ASP.NET Web API 隐式解释 HTTP 方法？

Question

似乎 ASP.NET 隐式地将名为 GetX 和 PostX 的方法分别解释为 GET 和 POST 方法，因为它们的名称以 HTTP 方法名称为前缀。 PUT 和 DELETE 也是如此。

不幸的是，我有一个名为 Delete 的方法，但我希望它被解释为 POST，因此我使用 [HttpPost] 属性明确指定它是一个 POST。这有效，只要它没有在接口(interface)内声明...

public interface IFooBarController
{
    [HttpPost]
    void DoSomething();

    [HttpPost]
    void Delete(int id);
}

public class FooBarController : IFooBarController
{
    public void DoSomething()
    {
       // This API method can only be called using POST,
       // as you would expect from the interface.
    }

    public void Delete(int id)
    {
        // This API method can only be called using DELETE,
        // even though the interface specifies [HttpPost].
    }
}

我该如何解决这个问题，而不必为每个实现指定 HttpPostAttribute？

Answer 1

接口(interface)属性的属性不会继承到类，您可以将接口(interface)设为抽象类。

从Microsoft找到答案:

The product team does not want to implement this feature, for two main reasons:

• Consistency with DataAnnotations.Validator
• Consistency with validation behavior in ASP.Net MVC
• tricky scenario: a class implements two interfaces that have the same property, but with conflicting attributes on them. Which attribute would take precedence?
