OAuth refreshToken

Questions
1

Hi all,
(although this is probably best answered by Patrick Ruhsert…)
Years ago I used Patrick’s ‘Google2’ plugin to do some cool OAuth stuff with Google, specifically I could use the “refreshToken” I got when authorising a service.
At the time I was using it to access Google Analytics, but now I want to use gMail.
I would store this in my database and when I wanted to access the service again, I would just use code like this

		if (ga_rec.ga_refresh_token) {
			status_msg('Current ga_refresh_token ' + ga_rec.ga_refresh_token);
			ga_rec.ga_access_token = plugins.Google2.getAccessToken(ga_rec.ga_refresh_token);
			status_msg('Access Token = ' + ga_rec.ga_access_token);
		} else {
			// get new refresh token
			ga_rec.ga_refresh_token = plugins.Google2.authorize(ga_rec.ga_auth_code, scopes.globals.ga_client_id, scopes.globals.ga_scopes);
			status_msg('New Refresh Token = ' + ga_rec.ga_refresh_token);
		}

I can see that there is a reference in the Wiki to a refreshToken

I have tried using this, and it kind of works if the ‘service’ that I have built is still valid, it will send an email with a new accessToken from

auth_gmail_token = gmail_service.refreshToken();

But I can’t see where/how I pass in the previously stored token to the ‘service’ if this is a new session??
I would expect a call like

auth_gmail_token = gmail_service.refreshToken(my_stored_token);

I tried

gmail_service.setAccessToken(my_stored_token);
auth_gmail_token = gmail_service.refreshToken();

but that threw an error & didn’t work.

[my analysis of the service build process is

  1. new session, so run ‘connect’ code
plugins.oauth.serviceBuilder(auth_clientId)
.clientSecret(auth_clientSecret)
.callback(scopes.auth.gmail_deeplink, 30)
.scope('https://mail.google.com/')
.build(plugins.oauth.OAuthProviders.GOOGLE);
  1. this makes web page appear for you to choose your gmail account to authorise
  2. once ‘allowed’, callback method is called
  3. if ‘success’, get ‘service’ and get accessToken from it and then one can email
function gmail_deeplink(result, auth_outcome) {
	if (result) {
		//SUCCESS
		gmail_service = auth_outcome;
		if ( my_stored_token != null ) {
			//gmail_service.setAccessToken(my_stored_token);
			auth_gmail_token = gmail_service.refreshToken();
		} else {
			// no stored token
			auth_gmail_token = gmail_service.getAccessToken();
			my_stored_token = gmail_service.getRefreshToken();
		}
  1. if the ‘connect’ method is called again, the deep link method is immediately fired and fails as ‘not success’ is passed
  2. if I add code to ‘connect’ method to see if ‘service’ already exists and then I try & fire deep link method passing “true” & “service”, it fails when I try to refreshToken (as I can’t pass it my valid, stored previous refreshToken to get new accessToken…
    /end analysis]

So, please, can someone clarify how to correctly use ‘refreshToken’ so I don’t have to keep asking user to allow access??
Thanks,
