检查从为ASP.NET MVC2编写的
http://lukesampson.com/post/471548689/entering-and-exiting-https-with-asp-net-mvc的示例代码,我注意到他们可以通过访问filterContext.ActionDescriptor和filterContext.ActionDescriptor.ControllerDescriptor来检查自定义属性是否应用于当前操作或控制器:
public class ExitHttpsIfNotrequiredAttribute : FilterAttribute,IAuthorizationFilter { public void OnAuthorization(AuthorizationContext filterContext) { // snip // abort if a [RequireHttps] attribute is applied to controller or action if(filterContext.ActionDescriptor.ControllerDescriptor.GetCustomAttributes(typeof(RequireHttpsAttribute),true).Length > 0) return; if(filterContext.ActionDescriptor.GetCustomAttributes(typeof(RequireHttpsAttribute),true).Length > 0) return; // snip } }
什么是ASP.NET MVC 1方法检查动作和控制器的自定义属性?在ASP.NET MVC 1中没有我可以告诉的filterContext.ActionDescriptor.
解决方法
更好更可靠*方法:
filterContext.ActionDescriptor.GetCustomAttributes( typeof(RequireHttpsAttribute),true).Count> 0
虽然这可能只是MVC 3.0.
