MVC4 Model Controllerdescriptor

1. Description of Controllerdescriptor

The Controller's action method has some of the following characteristics:

1.1 Actionnameattribute attribute he inherits from System.Web.Mvc.ActionNameSelectorAttribute abstract class

Actionnameselectorattribute uses its abstract method isvalidname to determine whether the specified action name matches the target action method.

The following code snippet:

After adding the Actionnameattribute attribute, the Access action will match the actionname instead of the actionnames note that there is a "s" Behind the Aciton method

        [ActionName ("actionname")]          Public actionresult actionnames ()        {            return Json ("", Jsonrequestbehavior.allowget);        }

Actionnameselectorattribute differs from Actionmethodselectorattribute: both have action filtering, which is for the action name and whether it matches the request

Httpget,httppost,httpput,httpdelete,httphead,httpoption,httppatch. The following code snippet:

[HttpGet]          Public actionresult HttpMethod ()        {            return Content ("");        }

1.3 Acceptverbsattribute characteristics, It differs from Actionmethodselectorattribute in that it can match multiple HTTP methods at the same time, as in the following code snippet:

This makes it possible to use a post or GET request at the same time, and if you remove get, you can only use the POST request.

   [Acceptverbs (Httpverbs.post |  Httpverbs.get)]       public  actionresult acceptverbs ()    {     return Json (" ", Jsonrequestbehavior.allowget);    }
