在控制器中查找特定的HttpGet操作

Question

Consider the following situation. In my controller I have:

public ActionResult Edit(int id)
{
  ...
}

[HttpPost]
public ActionResult Edit(Model model)
{
  ...
}

Also I have an ActionFilterAttribute , which applies to some other actions of the same controller. In the OnActionExecuting method I need to get the ActionDescriptor of the HttpGet Edit action:

public override void OnActionExecuting(ActionExecutingContext filterContext)
{
    // as this is called from the same controller, I use
    ActionDescriptor action = filterContext.ActionDescriptor.ControllerDescriptor
             .FindAction(filterContext.Controller.ControllerContext, "Edit");
    ...
}

The problem is, that the FindAction method returns "reference" to the HttpPost Edit action in case of POST requests. How do I make it to look only for HttpGet actions?

Answer 1

You can use maybe attribute ?

public class FooAttribute
    {


    }

[FooAttribute]
public ActionResult Edit(int id)
{
  ...
}

you can check OnActionExecution; example;

var isHasAttribute= filterContext.ActionDescriptor.IsDefined(typeof(FooAttribute), true);
