📝 [Feature] [v2]: Add a function to get the session expiry

[Amirreza hossein panah]

Feature Proposal Description

Currently, there is no clean and performant way to get session expiry, since there is a SetExpiry function it makes sense to have a function that returns the session expiry.

It can be done using something like this :

// middleware/session/session.go

// GetExpiry gets the expiration of this session
func (s *Session) GetExpiry() time.Duration {
	return s.exp
}

,

Alignment with Express API

This is something similar to :

req.session.cookie.expires  

HTTP RFC Standards Compliance

Confirmed.

API Stability

Hence we are only returning the exp variable which is already declared this feature will not have any stability issue.

Feature Examples

store, err := Seesion.Get(c)
	if err != nil {
		return err
	}
	exp := store.GetExpiry()

@amirrezaDev1378, we are planning a rewrite of the session for v3. No changes will be made to v2 as it is in maintenance-only mode at this point.

@sixcolors Oh, I didn't know that....
I will close the issue.

@sixcolors Should we keep this open and move it to v3?

Ref #2741, my plan is to replace the expires mechanism with an idle timeout approach, as it aligns better with the actual behavior of middleware. The plan for a hard expiry is to leave this as an implementation detail for the user which could be accomplished via a key from the session store. However, it would still be a good idea to allow for access to the idle timeout, probably without extending the session.
