嘿,我已经成功地可以在我的Filterattribute中使用属性注入,但是我想知道是否可能将它移动到构造函数中?
我当前的代码:
// AuthAttribute.cs public class AuthAttribute : ActionFilterattribute { public Roles _authRoles { get; private set; } [Inject] private readonly IAuthorizationService _service; public AuthAttribute(Roles roles) { _authRoles = roles; } public override void OnActionExecuting(ActionExecutingContext filterContext) { if (!filterContext.HttpContext.User.Identity.IsAuthenticated) { string redirectOnSuccess = filterContext.HttpContext.Request.Url.AbsolutePath; string redirectUrl = string.Format("?returnUrl={0}",redirectOnSuccess); string loginUrl = FormsAuthentication.LoginUrl + redirectUrl; filterContext.HttpContext.Response.Redirect(loginUrl,true); } else { bool isAuthorized = _service.Authorize(GetUserSession.Id,_authRoles.ToString()); if (!isAuthorized) { // Todo: Make custom "Not Authorized" error page. throw new UnauthorizedAccessException("No access"); } } } }
// TestController.cs [Auth(Roles.Developer)] public ActionResult Index() { // Some smart logic }
提前致谢!
解决方法
不,这不可能作为构建器
must be simple types的参数.
为了测试的目的,您可以使用另一个构造函数(因为您不应该在测试中使用IoC容器):
public class AuthAttribute : ActionFilterattribute { public Roles _authRoles { get; private set; } [Inject] private readonly IAuthorizationService _service; public AuthAttribute(Roles roles) { _authRoles = roles; } public AuthAttribute(Roles roles,IAuthorizationService authSvc) : this(roles) { this.service = authSvc; } // ... }
