从身份验证票证.NET FormsAuthentication通用校长 [英] .NET FormsAuthentication Generic Principal from Authentication Ticket

问题描述

有谁知道如何将一个通用的主体从表单添加到HttpContext的身份验证票证？

Does anyone know how to add a generic principal to the HTTPContext from the Forms Authentication Ticket?

推荐答案

您可以在 Application_AuthenticateRequest 事件做到这一点。 下面是一个例子的：

You could do this in the Application_AuthenticateRequest event. Here's an example:

protected void Application_AuthenticateRequest(Object sender, EventArgs e)
{
    var user = HttpContext.Current.User;
    if (user == null || !user.Identity.IsAuthenticated)
    {
        return;
    }
    // read the roles from the cookie and set a custom generic principal
    var fi = (FormsIdentity) HttpContext.Current.User.Identity;
    var fat = fi.Ticket;
    var astrRoles = fat.UserData.Split('|');
    HttpContext.Current.User = new GenericPrincipal(fi, astrRoles);
}
