Accessing Action Filter's data in Controller Action

[ApiBasicAuthorize]
public ActionResult SignIn()
{

}

I have this custom filter called ApiBasicAuthorize. Is it 开发者_JAVA百科possible to access ApiBasicAuthorize's data (properties etc) inside the controller action SignIn?

If not, how do I pass data from the filter to controller action?

There is a dictionary called items attached to the HttpContext object. Use this dictionary to store items shared across components during a request.

public override void OnAuthorization(AuthorizationContext filterContext)
{
    filterContext.HttpContext.Items["key"] = "Save it for later";

    base.OnAuthorization(filterContext);
}

Then anywhere in your code later in the request...

var value = HttpContext.Current.Items["key"];

    public override void OnAuthorization(AuthorizationContext filterContext)
    {
        var rd = filterContext.RouteData;

        //add data to route
        rd.Values["key"]="Hello";

        base.OnAuthorization(filterContext);
    }



public ActionResult(string key)
{
 //key= Hello
return View();
}
