将自定义IPrincipal和IIdentity与Ninject绑定

本文关键字：Ninject 绑定 IIdentity 自定义 IPrincipal | 更新日期: 2023-09-27 18:16:25

我试图将IIdentity从HttpContext.Current.User.Identity绑定到自定义IPrincipal，但从我可以收集到的，IIdentity在用户被认证之前是空的。

示例代码:

public interface ICustomPrincipal
{
    int UserID { get; set; }
}
public class CustomPrincipal : ICustomPrincipal
{
    private readonly IIdentity _identity;
    private readonly IUserRepository _userRepository;
    public CustomPrincipal(IIdentity identity, IUserRepository repository)
    {
        _identity = identity;
        _repository = repository;
    }
}

和

protected void Application_AcquireRequestState(object sender, EventArgs e)
{
    if (Request.IsAuthenticated && !Request.Url.AbsoluteUri.Contains(".axd"))
    {
        HttpContext.Current.User as CustomPrincipal;
    }
}

我可以绑定IUserRepository没有问题，但我不知道如何正确绑定IIdentity。

我试图在Application_Start上的CreateKernel()中绑定HttpContext.Current.User.Identity，但问题是，IIdentity为空。

我也尝试过使用GlobalFilters和Ninject。BindFilter方法来设置CustomPrincipal，但问题又回到了IIdentity为空。

我不想调用CustomPrincipal的构造函数，因为IUserRepository也涉及构造函数注入。

我不确定我是否绑定不正确，或者我的实现方法不正确，任何想法或建议都将非常感谢。

我最后想要实现的是将ICustomPrincipal传递到DB级别，以记录事务上的UserID。

谢谢

下面是一个示例，显示了bootstrap AFTER和BEFORE身份验证

public class MvcApplication : System.Web.HttpApplication
{
    protected void Application_Start()
    {
        FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
        RouteConfig.RegisterRoutes(RouteTable.Routes);
        BundleConfig.RegisterBundles(BundleTable.Bundles);
        //WebApiConfig.Register(GlobalConfiguration.Configuration);
        //BundleMobileConfig.RegisterBundles(BundleTable.Bundles);
    }
    private bool _isBootStrapped;
    private bool _isBootStrappedAuthenticated;
    public override void Init()
    {
        base.Init();
        // handlers managed by ASP.Net during Forms authentication
        BeginRequest += new EventHandler(BeginRequestHandler);
        PostAuthorizeRequest += new EventHandler(PostAuthHandler);
        EndRequest += new EventHandler(EndRequestHandler);
    }
    public void EndRequestHandler(object sender, EventArgs e)
    {
    }
    public void BeginRequestHandler(object sender, EventArgs e)
    {
        BootStrapUnauthentiated();
    }
    public void PostAuthHandler(object sender, EventArgs e)
    {
        if (_isBootStrappedAuthenticated)
        {
            return; // nuff done...
        }
        BootStrapAuthenticated();
        BootStrapUnauthentiated();
    }
    private void BootStrapAuthenticated()
    {
        if (Request.IsAuthenticated)
        {
            BootStrapHttp(Context);
            BootStrapper.RegisterInfrastureAdapters();
            _isBootStrapped = true;
            _isBootStrappedAuthenticated = true;
        }
    }
    private void BootStrapUnauthentiated()
    {
        if (!_isBootStrapped)
        { // minimal bootstrap for launch but user not yet known, eg logon screen
            BootStrapHttp(Context);
            BootStrapper.RegisterInfrastureAdapters();
           _isBootStrapped = true; // just a connection, if no persisted cookie, the may not be authenticated yet
        }
    }
}
