依赖注射传递ASP.NET用户 [英] Passing ASP.NET User by Dependency Injection

问题描述

在我的web应用程序我有需要访问当前已验证用户（HttpContext.User中）各种组件。

In my web application I have various components that need to access the currently authenticated user (HttpContext.User).

有两个明显的方式，组件可以访问此：
1）访问从HttpContext.Current获取用户
2）各地传递用户在构造函数中

There are two obvious ways a component can access this: 1) Accessing getting the User from HttpContext.Current 2) Passing the user around in constructors

1. 是不理想的，因为它使测试难度和领带应用程序组件的网络关注，当他们真的不应该知道这一点。


2. 仅仅是混乱和复杂的一切。

所以，我一直在思考在当前用户传递（或者仅仅是名称/ ID）使用IoC容器它需要的任何组件（通过依赖注入）。

So I've been thinking about passing in the current user (or perhaps just the name/id) to any component that needs it using an IoC container (via dependency injection).

时使用这种技术来提供当前ASP.NET用户对应用程序的部分人？或者说，这听起来像一个明智的做法？我想知道这是如何制定的人。

Is anyone using this technique to supply the current ASP.NET user to parts of the application? Or, Does this sound like a sensible approach? I would like know how this has worked out for people.

感谢

更新：
感谢拉吉一个很好的例子。如果任何人有使用AutoFac一个类似的例子这将是更AP preciated！

UPDATE: Thanks to Raj for a great example. If anyone has a similar example using AutoFac it would be much appreciated!

UPDATE2：谢谢你的答案，希望我能分裂接受

UPDATE2: Thanks for the answers, wish I could have split the accept!

推荐答案

在autofac：

builder.Register（C => HttpContext.Current.User.Identity）.HTT prequestScoped（）;

builder.Register(c => HttpContext.Current.User.Identity).HttpRequestScoped();
