Get access token after client authorization

Hi i am building a JavaFX application for Google Drive with basic functionality as (download,upload etc). I am using JavaFX Browser for user Authentication , so i can navigate to the URL and then get the html code .

1)I need to get the Authentication URL 2)I will authenticate with JavaFX Browser , so my question is : -> is the access token shown on the html code?

How to figure the method authorize of DriveSample to return me the Authentication URL :

 /**
   * Authorizes the installed application to access user's protected data.
   */
  private static Credential authorize() throws Exception {
    // load client secrets
    GoogleClientSecrets clientSecrets = GoogleClientSecrets.load(JSON_FACTORY,
        new InputStreamReader(DriveSample.class.getResourceAsStream("/client_secrets.json")));
    if (clientSecrets.getDetails().getClientId().startsWith("Enter")
        || clientSecrets.getDetails().getClientSecret().startsWith("Enter ")) {
      System.out.println(
          "Enter Client ID and Secret from https://code.google.com/apis/console/?api=drive "
              + "into drive-cmdline-sample/src/main/resources/client_secrets.json");
      System.exit(1);
    }
    // set up authorization code flow
    GoogleAuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow.Builder(httpTransport,
        JSON_FACTORY, clientSecrets, Collections.singleton(DriveScopes.DRIVE_FILE))
            .setDataStoreFactory(dataStoreFactory).build();

    // authorize
    return new AuthorizationCodeInstalledApp(flow, new LocalServerReceiver()).authorize("user");

  }

problem occurred because of headless system of spring boot, headless system’s can’t open browser so use this below code to set headless false in spring boot

public static void main(String[] args) { SpringApplicationBuilder builder = new SpringApplicationBuilder(App.class); builder.headless(false).run(args); }
