获取ActionName，ControllerName和AreaName并将其传递给ActionFilter属性 [英] Get ActionName, ControllerName and AreaName and pass it in ActionFilter Attribute

问题描述

我使用如下所示的自定义AuthorizationFilter:

I use a custom AuthorizationFilter like the followings:

public class ActionAuthorizeAttribute : AuthorizeAttribute {

protected override bool AuthorizeCore(System.Web.HttpContextBase httpContext) {

        if(!httpContext.User.Identity.IsAuthenticated)
            return false;

        if(IsUserExcluded())
            return false;
        else
            return IsRoleAuthorize(httpContext);
    }
}

我在每个操作的顶部都使用此过滤器，并且要检查是否被授权，需要操作名称，控制器名称和区域名称.因此，有什么方法可以像System.Web.HttpContextBase这样在AuthorizeCore()方法中获取此名称?如果答案为否"，那么我如何获得该名称并将其传递给属性，显然我不想手动添加每个名称，实际上是在控制器中类似于ViewContext.RouteData.Values["Controller"]的内容:

I use this filter at the top of each action I have, and for check Is Authorized, need Action Name, Controller Name, And Area Name. So is there any way to get this names in AuthorizeCore() method like use System.Web.HttpContextBase? if answer is No then how can I get this names and pass it to attribute, obviously I don't want to add each name by hand, actually something likeViewContext.RouteData.Values["Controller"] in controllers:

[ActionAuthorize(actionName=Action, controller=ControllerName, area=AreaName)]
public ActionResult Index() {
    return View();
}

有人对此有任何想法吗?

Does any one have any idea about it?

推荐答案

您可以从RouteData中获取它们:

You could fetch them from the RouteData:

protected override bool AuthorizeCore(System.Web.HttpContextBase httpContext)
{
    var rd = httpContext.Request.RequestContext.RouteData;
    string currentAction = rd.GetRequiredString("action");
    string currentController = rd.GetRequiredString("controller");
    string currentArea = rd.Values["area"] as string;

    ...

}
