这是一个smaple动作过滤器,我们知道当我们编写动作过滤器时,我们需要像这样装饰控制器来为任何特定的控制器实现它,但是我想知道有没有办法编写动作过滤器,它将适用于所有控制器,我不需要用动作过滤器属性来装饰控制器.任何的想法.
[LogActionFilter]
public class HomeController : Controller
{}
public class LogActionFilter : ActionFilterAttribute
{
public override void OnActionExecuting(ActionExecutingContext filterContext)
{
Log("OnActionExecuting",filterContext.RouteData);
}
public override void OnActionExecuted(ActionExecutedContext filterContext)
{
Log("OnActionExecuted",filterContext.RouteData);
}
private void Log(string methodName,RouteData routeData)
{
var controllerName = routeData.Values["controller"];
var actionName = routeData.Values["action"];
var message = String.Format("{0} controller:{1} action:{2}",methodName,controllerName,actionName);
Debug.WriteLine(message,"Action Filter Log");
}
}
解决方法
public class LogActionFilterAttribute : IActionFilter
{
public void OnActionExecuted(ActionExecutedContext filterContext)
{
Log("OnActionExecuted",filterContext.RouteData);
}
public void OnActionExecuting(ActionExecutingContext filterContext)
{
Log("OnActionExecuting",filterContext.RouteData);
}
private void Log(string methodName,RouteData routeData)
{
var controllerName = routeData.Values["controller"];
var actionName = routeData.Values["action"];
var message = String.Format("{0} controller:{1} action:{2}",actionName);
Debug.WriteLine(message,"Action Filter Log");
}
}
public class MvcApplication : System.Web.HttpApplication
{
protected void Application_Start()
{
GlobalFilters.Filters.Add(new LogActionFilterAttribute());
}
}
