google-signin / GoogleCredential

[pithon.philip...@gmail.com]

Hi!

I want to use signin for drive API

https://developers.google.com/drive/web/quickstart/java

To work with Drive, I must have GoogleCredential object

If I use google-signin with offline propertie, it's ok :

https://developers.google.com/identity/sign-in/web/server-side-flow

example :

public String getRefreshToken(String code) throws IOException {

GoogleTokenResponse response = new GoogleAuthorizationCodeTokenRequest(new NetHttpTransport(),

new JacksonFactory(), clientid, clientsecret, code, redirectUrl).execute();

return response.getRefreshToken();

}

BUT... how get GoogleCredential without offline... for web applications ????

I can't find documentation

thank you in advance for your ideas !
