not receiving “Refresh Token” even in the first consent - Google API

问题

I'm being redirected to the Google Consent for the first time and asked if I allow this application to manage Gmail account and stuff. And when I'm redirected back, refresh token is null.

  +token:"ya29.Gls1BTQIRIuCW2dnzIpQlciOZNpidhjfsoidjfsomethingsm"
  +refreshToken: null
  +expiresIn: 3600

I know Refresh Token comes null on subsequent requests. But this was the first request I made.

Is there something I need to do on the console side.

回答1:

Solved it. I forgot to set access_type to offline

$client->setAccessType('offline');

In my case I was using Larave/Socialite

Socialite::driver('google')->with(['access_type'=>'offline'])->redirect();
