在我正在创建的MVC项目中,我有以下内容RequirePermissionAttribute可以放在需要特定权限的任何操作上(本例中已简化):

public class RequirePermissionAttribute : ActionFilterAttribute, IAuthorizationFilter
{
    public Operation Permissions { get; set; }

    public RequirePermissionAttribute() { }

    public RequirePermissionAttribute(Operation permissions)
    {
        this.Permissions = permissions;
    }

    public bool AuthorizeCore(HttpContextBase httpContext)
    {
        IAuthorizationService authServ = new ASPNETAuthorizationService();
        return authServ.Authorize(httpContext);
    }

    public void OnAuthorization(AuthorizationContext filterContext)
    {
        Enforce.ArgNotNull(filterContext);

        if (this.AuthorizeCore(filterContext.HttpContext))
        {
            // code snipped.
        }
        else
        {
            // code snipped.
        }
    }
}

所以问题显然是我的authorize属性依赖于ASPNETAuthorizationService我创建的属性.我不能去构造函数方式,因为属性是编译时检查的.

有一点需要提及的是,我正在使用自己制作的小IoC,并且它还没有支持属性注入(尚未).当然,如果我确实去了房产注入路线,我必须增加对它的支持(我必须做一些研究).

将某些东西注入属性类的最佳方法是什么？

我试图将依赖注入到自定义中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;
    }
}

这有效,但似乎是作为一个单身人士解决,这意味着我得到了我以前的问题中描述的问题

我想要做的是使用属性注入但由于我的属性本身没有被Unity解决,我无法找到一种方法来配置容器来拦截和解析属性.我尝试过以下方法:

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

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