Custom IIdentity and passing data from an attribute to a controller
- by DM
Here's my scenario:
I've successfully created a custom IIdentity that I pass to a GenericPrincipal. When I access that IIdentity in my controller I have to cast the IIdentity in order to use the custom properties. example:
public ActionResult Test()
{
MyCustomIdentity identity = (MyCustomIdentity)User.Identity;
int userID = identity.UserID;
...etc...
}
Since I need to do this casting for nearly every action I would like to wrap this functionality in an ActionFilterAttribute. I can't do it in the controller's constructor because the context isn't initialized yet. My thought would be to have the ActionFilterAttribute populate a private property on the controller that I can use in each action method. example:
public class TestController : Controller
{
private MyCustomIdentity identity;
[CastCustomIdentity]
public ActionResult()
{
int userID = identity.UserID;
...etc...
}
}
Question: Is this possible and how? Is there a better solution? I've racked my brain trying to figure out how to pass public properties that are populated in an attribute to the controller and I can't get it.
