我正在尝试将依赖项注入到自定义中AuthorizeAttribute，如下所示：

public class UserCanAccessArea : AuthorizeAttribute
{
    readonly IPermissionService permissionService;

    public UserCanAccessArea() :
        this(DependencyResolver.Current.GetService<IPermissionService>()) { }

    public UserCanAccessArea(IPermissionService permissionService)
    {
        this.permissionService = permissionService;
    }

    protected override bool AuthorizeCore(HttpContextBase httpContext)
    {
        string AreaID =
            httpContext.Request.RequestContext.RouteData.Values["AreaID"] as string;

        bool isAuthorized = false;

        if (base.AuthorizeCore(httpContext))
            isAuthorized = permissionService.UserCanAccessArea(AreaID, httpContext.User);

        return isAuthorized;
    }
}

这是可行的，但似乎可以作为一个单例解决，这意味着我得到了我以前的问题中描述的问题

我想做的是使用属性注入，但是由于我的属性本身无法被Unity解析，因此我无法找到一种方法来配置容器以拦截和解析属性。我尝试了以下方法：

public class UserCanAccessArea : AuthorizeAttribute
{
    public IPermissionService permissionService { get; set; }

    protected override bool AuthorizeCore(HttpContextBase httpContext)
    {
        string AreaID =
            httpContext.Request.RequestContext.RouteData.Values["AreaID"] as string;

        bool isAuthorized = false;

        if (base.AuthorizeCore(httpContext))
            isAuthorized = permissionService.UserCanAccessArea(AreaID, httpContext.User);

        return isAuthorized;
    }
}

容器：

container.RegisterType<UserCanAccessArea>(new InjectionProperty("permissionService"));

但是该属性在运行时始终为null。

有没有人做到这一点，如果有，您有榜样吗？
