在ASP.NET对象持久化（后背上之间） [英] Object persistence (between post-backs) in ASP.NET

问题描述

我在开发一个相当大的web应用程序的过程。多级访问已通过ASP.NET成员资格和角色提供者定义。个人用户也有配置文件（我已经扩展到包括多种任意信息）。

I am in the process of developing a quite large web app. Multiple levels of access have been defined via ASP.NET Membership and Role providers. Individual users also have profiles (which I have extended to include a variety of arbitrary info).

问题是我怎么坚持后背上的用户？

The question is how do I persist the user between post backs?

我可以使用类似HttpContext.Current存储用户，但它的寿命只有从一后回到另一个。这是我的理解，我将不得不在后回（的OnInit / pageLoad的）的开始检索用户对象，然后将其放回HttpContext的在每个回帖子的结尾。似乎有点效率低下。

I could use something like HttpContext.Current to store the user, but its lifespan is only from one post-back to another. It's my understanding that I would have to retrieve the user object at the beginning of the post-back (OnInit/PageLoad) and then drop it back in the HttpContext at the end of each post-back. Seems kind of inefficient.

（我不知道如果我能做到这一点有一个HttpModule？）

(I wonder if i can do this with an HttpModule?)

此外，即使是ASP.NET它只是一个普通的用户一个静态的currentUser实例。我需要携带整个轮廓（这是我在SQL创建）。

Also, even though there is a static CurrentUser instance in ASP.NET it is simply a generic User. I need to carry the entire profile (which I created in SQL).

要回顾一下，问题是：A）是可以延长由ASP.NET提供的静态的currentUser实例，以便在被通过正常渠道坚持将携带任意信息？如果没有，我怎么能坚持在整个用户会话的持续时间等静态信息（直到用户注销或会话过期/超时事件是由在Global.asax解雇）？

To recap, the question is: a) is it possible to extend the static CurrentUser instance given by ASP.NET so that it would carry arbitrary information while being persisted through normal channels? If No, how can I persist such static information throughout the duration of the User session (until the user either logs off, or the Session Expire/Timeout event is fired by the global.asax)?

任何帮助将大大AP preciated！
谢谢！

推荐答案

使用挂接到PostAuthenticateRequest一个IHttpModule的，那么你的用户存储在HttpContext.Current.User

Use an IHttpModule that hooks into the PostAuthenticateRequest, then store your user in the HttpContext.Current.User

例如：

public class MyModule : IHttpModule
{
    public void Init(HttpApplication context)
    {
        context.PostAuthenticateRequest += PostAuthenticateRequest;
    }

    private void PostAuthenticateRequest(object sender, EventArgs e)
    {
        var app = (HttpApplication)sender;
        var httpContext = app.Context;
        IMyPrincipal principal = null;

        principal = new MyPrincipal(httpContext.User.Identity);

        httpContext.User = principal;
    }
}
