Getting authorization code

The authCode that is being returned is the one-time code that you can send to your backend server, so that the server can exchange for its own access_token and refresh_token.

The access_token and refresh_token can be saved in backend storage for reuse and refresh. In this way, you can avoid exposing your api key or secret key whenever you need to use various google APIs.

const authCode = await this.$gAuth.getAuthCode()
const response = await this.$http.post('http://your-backend-server-api-to-use-authcode', { code: authCode, redirect_uri: 'postmessage' })

Sign-in: Directly get back the access_token and id_token

const googleUser = await this.$gAuth.signIn()
// googleUser.getId() : Get the user's unique ID string.
// googleUser.getBasicProfile() : Get the user's basic profile information.
// googleUser.getAuthResponse() : Get the response object from the user's auth session. access_token and so on
this.isSignIn = this.$gAuth.isAuthorized

refer to google signIn reference : GoogleUser

Sign-out

Handling Google sign-out

const response = await this.$gAuth.signOut()

Extra - Directly get access_token and refresh_token on Server-side

To get access_token and refresh_token in server side, the data for redirect_uri should be postmessage. postmessage is magic value for redirect_uri to get credentials without the actual redirect uri.

Curl

curl -d "client_id=YOUR_CLIENT_ID&\
  client_secret=YOUR_CLIENT_SECRET&\
  redirect_uri=postmessage&\
  grant_type=authorization_code&\
  code=YOUR_AUTH_CODE" https://accounts.google.com/o/oauth2/token
