为什么没有在的ASP.NET Web API 2的AuthenticationFilterAttribute类？ [英] Why isn't there an AuthenticationFilterAttribute class in ASP.NET Web API 2?

问题描述

的ASP.NET Web API 2自带的 5家滤清器接口的：

ASP.NET Web API 2 comes with five filter interfaces:

• IActionFilter


• IAuthenticationFilter


• 个IAuthorizationFilter


• 个IExceptionFilter


• IOverrideFilter

• IActionFilter
• IAuthenticationFilter
• IAuthorizationFilter
• IExceptionFilter
• IOverrideFilter

所有这些接口都有内置的实现（如 ActionFilterAttribute ， AuthorizationFilterAttribute ），除了 IAuthenticationFilter 。是否有针对或有网页API的开发者根本忘了为特定接口的实现？

All of those interfaces have built-in implementations (e.g. ActionFilterAttribute, AuthorizationFilterAttribute), except for IAuthenticationFilter. Is there a reason for that or have Web API devs simply forgot to provide an implementation for that particular interface?

更新

阅读伊沙伊Galatzer的回答后，我结束了实施失踪的属性，并将其上传到Nuget.org：的 https://www.nuget.org/packages/WebApi.AuthenticationFilter

After reading Yishai Galatzer's answer I ended up implementing the "missing" attribute and uploaded it to Nuget.org: https://www.nuget.org/packages/WebApi.AuthenticationFilter

推荐答案

由于我们不希望用户共同使用一个AuthenticationFilter。这不是把它前面和中心的一个方式。

Because we don't expect the common user to use an AuthenticationFilter. This is a way of not putting it front and center.
