ASP.NET IAuthorizationFilter OnAuthorization

Question

您好，我正在尝试实现一个自定义授权过滤器

 //The Authourization attribute on a controller
public class CustomAdminAuthorizationFilter : IAuthorizationFilter
{
    private readonly IAuthentication _authentication;

    public SageAdminAuthorizationFilter(IAuthentication authentication)
    {
        _authentication = authentication;
    }

    public void OnAuthorization(AuthorizationContext filterContext)
    {
       bool result = _authentication.Authorize(filterContext.HttpContext);
    }
}

正如您在OnAuthorization上看到的，我得到的结果是真或假。我需要设置什么才能返回我原来的位置？

编辑：

它似乎仍然让我直接跳转到登录页面

我确实注入了IAuthetication

 this.BindFilter<CustomAdminAuthorizationFilter>(FilterScope.Controller, 0);
   Bind<IAuthentication>().To<CustomAuthenticationService>();

然后，我在控制器中这样装饰我的操作。

[Authorize]
    public ActionResult Index()
    {
        ViewBag.Title = "Welcome";
        ViewBag.Message = "Welcome to ASP.NET MVC!";

        return View();
    }

在我的web.config中，我使用

<authentication mode="Forms">
  <forms loginUrl="~/Account/LogOn" timeout="2880" />
</authentication>

这应该被改变吗？

任何帮助都将不胜感激。

将其更改为Attribute，而不是简单的IAuthorizationFilter

[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method)]
public class SageAdminAuthorizeAttribute : AuthorizeAttribute, IAuthorizationFilter
{
    readonly IAuthentication _authentication;

    public SageAdminAuthorizeAttribute(IAuthentication authentication)
    {
        _authentication = authentication;
    }

    public override void OnAuthorization(AuthorizationContext filterContext)
    {
        if (!_authentication.Authorize(filterContext.HttpContext))
            filterContext.Result = new HttpUnauthorizedResult();
    }
}

现在，使用新的[SageAdminAuthorize]属性而不是使用[Authorize]

[SageAdminAuthorize]
public ActionResult Index()
{
    ViewBag.Title = "Welcome";
    ViewBag.Message = "Welcome to ASP.NET MVC!";

    return View();
}
