fix: in case there is a port number other than 80 or 443

[mihui]

const strategy = new Strategy({
  config: myConfig, scope: myScope,
  callbackURL: 'https://localhost:8080/callback',
}, myVerifyFunc);

// serializeUser, deserializeUser, etc...

passport.use('my-strategy', strategy);

When the callback request reach to the callback URL, it says:

CSIAQ0167E The redirection URI that is provided in the request [https://localhost/callback] is either invalid, or does not meet the matching criteria for the registered redirection URI.

Apparently the port number is missing...

Are you using express@5? Because AFAICT req.host is fixed in express 5 and properly returns port.

If you don't use the latest express version where this is fixed or use some other non-standard setup - you can just overload the currentUrl Strategy instance/prototype method so that it works for your conditions, that's the whole reason why this method is public and typed - so that you can control it.

OK, sounds good. BTW I am using "express": "^4.21.1"
