如何用java编写批处理程序，以便在Google Drive中上载文件？

我已经写了一些代码，是上传图像成功地在谷歌驱动器，但我需要复制在浏览器中的授权代码，我们运行这个项目后，在浏览器中得到的代码。我需要在控制台中复制此代码，然后它就可以正常工作了

但是我正在尝试制作用于上传图像的批处理文件，所以不需要这些手工工作。 请帮帮我。 提前谢谢

这是我的密码：

/**
 * Client id from GD.
 */
private static String CLIENT_ID = "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX";
/**
 * Client secret key from GD.
 */
private static String CLIENT_SECRET = "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX";

/**
 * Redirect url from GD.
 */
private static String REDIRECT_URI = "XXXXXXXXXXXXXXXXXXXXXXXXXX";

  public static void main(String[] args) throws IOException {

    HttpTransport httpTransport = new NetHttpTransport();
    JsonFactory jsonFactory = new JacksonFactory();

    GoogleAuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow.Builder(
        httpTransport, jsonFactory, CLIENT_ID, CLIENT_SECRET, Arrays.asList(DriveScopes.DRIVE))
        .setAccessType("online")
        .setApprovalPrompt("auto").build();

    String url = flow.newAuthorizationUrl().setRedirectUri(REDIRECT_URI).build();
    System.out.println("Please open the following URL in your browser then type the authorization code:");
    System.out.println("  " + url);
    BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
    String code = br.readLine();

    GoogleTokenResponse response = flow.newTokenRequest(code).setRedirectUri(REDIRECT_URI).execute();
    GoogleCredential credential = new GoogleCredential().setFromTokenResponse(response);

    //Create a new authorized API client
    Drive service = new Drive.Builder(httpTransport, jsonFactory, credential).build();

    //Insert a file  
    File body = new File();
    body.setTitle("imagename");
    body.setDescription("A test document");
    body.setMimeType("image/jpeg");

    java.io.File fileContent = new java.io.File("icon.jpg");
    FileContent mediaContent = new FileContent("image/jpeg", fileContent);

    File file = service.files().insert(body, mediaContent).execute();
    System.out.println("File ID: " + file.getId());

您只需在第一次运行应用程序时通过授权流程。然后，您可以存储刷新令牌并使用它构建授权请求所需的凭据对象。刷新令牌的时间持续到用户手动撤销为止。

您能给我发送刷新令牌的代码示例吗。我找不到它。感谢检查此页面中所有与授权相关的代码段：
