c# - 覆盖用户的 IIdentity 属性

Question

我为我的 MVC 项目开发了一个简单的 IIdentity 和 IPrincipal，我想覆盖 User 和 User。 Identity 以正确的类型返回值

这是我的自定义身份:

public class MyIdentity : IIdentity
{
    public MyIdentity(string name, string authenticationType, bool isAuthenticated, Guid userId)
    {
        Name = name;
        AuthenticationType = authenticationType;
        IsAuthenticated = isAuthenticated;
        UserId = userId;
    }

    #region IIdentity
    public string Name { get; private set; }
    public string AuthenticationType { get; private set; }
    public bool IsAuthenticated { get; private set; }
    #endregion

    public Guid UserId { get; private set; }
}

这是我的自定义委托(delegate)人:

public class MyPrincipal : IPrincipal
{
    public MyPrincipal(IIdentity identity)
    {
        Identity = identity;
    }


    #region IPrincipal
    public bool IsInRole(string role)
    {
        throw new NotImplementedException();
    }

    public IIdentity Identity { get; private set; }
    #endregion
}

这是我的自定义 Controller ，我成功更新了 User 属性以返回我的自定义主体类型:

public abstract class BaseController : Controller
{
    protected new virtual MyPrincipal User
    {
        get { return HttpContext == null ? null : HttpContext.User as MyPrincipal; }
    }
}

如何以相同的方式让 User.Identity 返回我的自定义身份类型？

Answer 1

您可以在您的 MyPrincipal 类中显式实现 IPrincipal，并添加您自己的 Identity 类型的 MyIdentity 属性.

public class MyPrincipal : IPrincipal 
{
    public MyPrincipal(MyIdentity identity)
    {
        Identity = identity;

    }

    public MyIdentity Identity {get; private set; }

    IIdentity IPrincipal.Identity { get { return this.Identity; } }

    public bool IsInRole(string role)
    {
        throw new NotImplementedException();
    }
}
