是什么在asp.net之间HttpContext.Current.User和Thread.CurrentPrincipal中的区别？ [英] What's the difference between HttpContext.Current.User and Thread.CurrentPrincipal in asp.net?

问题描述

好吧，我觉得冠军是非常明显的。

Well, I think the title is clear enough.

推荐答案

最大的区别是，他们不必是相同的。

The biggest difference is that they do not have to be the same.

一般而言，HttpContext.Current.User是登录用户，同时是Thread.CurrentPrincipal中的工作进程标识。

Generally speaking, HttpContext.Current.User is the logon user while Thread.CurrentPrincipal is the worker process identity.

在IIS 5.x中，通过Thread.CurrentPrincipal中默认ASPNET。在IIS 6及以上，通过Thread.CurrentPrincipal中默认为网络服务或应用程序池帐户。

On IIS 5.x, Thread.CurrentPrincipal by default is ASPNET. On IIS 6 and above, Thread.CurrentPrincipal by default is Network Service or application pool account.

要使它复杂，如果启用ASP.NET模拟，然后他们两个将是相同的登录用户。 ：）

To make it complex, if you enable ASP.NET impersonation, then both of them will be the same as the logon user. :)

尝试阅读关于这一主题一些非常好的书籍和微软MSDN文章

另一个建议是使用调试器附加到工作进程，并检查这些在运行时。这可以给你一个更好看。

Another suggestion is to use a debugger to attach to the worker process and check those at runtime. That can give you a better look.
