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' })
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
Handling Google sign-out
const response = await this.$gAuth.signOut()
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 -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
