如何在OnActionExecuting中获取控制器和操作名称？

Posted 2021-03-27

是否可以找出OnActionExecuting中当前正在执行的控制器/操作？

答案

您可以尝试ActionDescriptor的ActionExecutingContext如下：

protected override void OnActionExecuting(ActionExecutingContext filterContext)
{
   string actionName = filterContext.ActionDescriptor.ActionName;
   string controllerName = filterContext.ActionDescriptor.ControllerDescriptor.ControllerName
   .....
   base.OnActionExecuting(filterContext);
}

另一答案

你可以使用ActionDescriptor的ActionExecutingContext

protected override void OnActionExecuting(ActionExecutingContext filterContext)
{
    var descriptor = filterContext.ActionDescriptor;
    var actionName = descriptor.ActionName;
    var controllerName = descriptor.ControllerDescriptor.ControllerName;
    ......
    base.OnActionExecuting(filterContext);
}

另一答案

你可以看看RouteData：

    Request.RequestContext.RouteData.Values["Controller"];
    Request.RequestContext.RouteData.Values["Action"];

另一答案

ActionExecutingContext上下文这将是你的上下文....

var actionName = ((Microsoft.AspNetCore.Mvc.Controllers.ControllerActionDescriptor)context.ActionDescriptor).ActionName;
var controllerName = ((Microsoft.AspNetCore.Mvc.Controllers.ControllerActionDescriptor)context.ActionDescriptor).ControllerName;

另一答案

var controllerName = (string)routingValues["controller"];

var actionName = (string)routingValues["action"];
