asp.net-core - ASP.NET Core 2.0 从 AuthorizationHandler、HandleRequirementAsync 方法重定向用户

Question

我正在尝试在 .net core 2.0 中实现 AuthorizationHandler 在那里我需要授权用户并根据条件想要重定向到我的应用程序验证中的不同操作方法工作正常但是我如何将用户重定向到拒绝访问或登录页面时授权失败。

 protected override Task HandleRequirementAsync(AuthorizationHandlerContext context, HasPermissionRequirement requirement)
    {
        var controllerContext = context.Resource as AuthorizationFilterContext;

        if (sessionManager.Session.sysUserID <= 0)
        {
            controllerContext.Result = new RedirectToRouteResult(new RouteValueDictionary(new { controller = "Account", action = "Login", area = "" }));

            return Task.FromResult(0);
        }


            if (Utilities.GetInt32Negative(PermissionID) == 1 || Utilities.GetInt32Negative(PermissionID) == -1)
            {
                if (!PagePath.Equals("~/"))
                    controllerContext.Result = new RedirectToRouteResult(new RouteValueDictionary(new { controller = "Home", action = "NoAccess", area = "" }));
            }

            context.Succeed(requirement);
        }
        else
        {
            if (!PagePath.Equals("~/"))
                controllerContext.Result = new RedirectToRouteResult(new RouteValueDictionary(new { controller = "Home", action = "NoAccess", area = "" }));
        }

        return Task.FromResult(0);
    }

我找到了解决方案，我希望这能帮助寻找类似的人，在自定义授权中，我们可以使用 重定向到任何所需的 Controller 操作。 AuthorizationFilterContext 和 RedirectToActionResult

protected override Task HandleRequirementAsync(AuthorizationHandlerContext context, HasPermissionRequirement requirement)
{
    // Get the context       
    var redirectContext = context.Resource as AuthorizationFilterContext;
    //check the condition 
    if (!result)
    {
        redirectContext.Result = new RedirectToActionResult("AccessDenied", "Home", null);
        context.Succeed(requirement);
        return Task.CompletedTask;
    }
    context.Succeed(requirement);
    return Task.CompletedTask;
}
