GetTypedHeaders().SetCookie in .net core

Question

Team, I am trying to access the response cookies in a result filter - OnResultExecuted like

var setCookieHeaderValues = context.Response.GetTypedHeaders().SetCookie;

I also tried using the OnStarting delegate on context.HttpContext.Response, however it never returns the cookies which are in set-cookie rather it is always returning an empty object. Am I missing something here? Please help.

Note, that I can see the response cookies in the chrome - dev tools 1) Application - Storage - Cookies and 2) Network - Cookies - Response Cookies

Hi, @Karthik K V ,

You could try coding as below ：

Codes of MyActionFilterAttribute :

public class MyActionFilterAttribute : ActionFilterAttribute  
{  
    public override void OnResultExecuted(ResultExecutedContext filterContext)  
    {  
        var setCookieHeaderValues = filterContext.HttpContext.Response.Headers;  

        var cookies = setCookieHeaderValues["Set-Cookie"];  
    }  
}  

Codes of HomeController:

[MyActionFilterAttribute]  
    public class HomeController : Controller  
    {  
  
        public HomeController()  
        {  
        }  
  
        public IActionResult Index()  
        {  
           Response.Cookies.Append("Test", "hellocookie");  
  
            return View();  
        }  
  
    }
