在ASP.NET 5中获取AuthenticationProperties [英] Get AuthenticationProperties in ASP.NET 5

问题描述

在ASP.NET 5 MVC 6 RC1中，如何从控制器或过滤器中检索AuthenticationProperties? HttpContext.Authentication似乎没有此功能.

In ASP.NET 5 MVC 6 RC1 how do I retrieve AuthenticationProperties from within a controller or from a filter? HttpContext.Authentication does't seem to have this functionality.

我考虑过要注册一个CookieAuthenticationEvents.OnValidatePrincipal处理程序，然后在CookieValidatePrincipalContext参数上使用Properties属性.然后，我可以将那些AuthenticationProperties存储在请求缓存中，以便以后可以获取诸如IssuedUtc之类的东西.

I thought about registering an CookieAuthenticationEvents.OnValidatePrincipal handler and then using the Properties property on the CookieValidatePrincipalContext argument. Then I could store those AuthenticationProperties in the request cache so that later I'm able to get things like IssuedUtc.

是否有更好的解决方案，不需要我自己存储?

Is there a better solution where I don't need to store this myself?

我没有使用ASP.NET Identity，而是将cookie中间件作为独立软件使用.

I'm not using ASP.NET Identity but the cookie middleware as standalone.

推荐答案

在ASP.NET 5中，检索身份验证属性有些麻烦，因为必须实例化AuthenticateContext:

In ASP.NET 5, retrieving the authentication properties is a bit cumbersome as it must be done by instantiating an AuthenticateContext:

var context = new AuthenticateContext("[your authentication scheme]");
await HttpContext.Authentication.AuthenticateAsync(context);

if (context.Principal == null || context.Properties == null) {
    throw new InvalidOperationException("The request is not authenticated.");
}

var properties = new AuthenticationProperties(context.Properties);
