Question

我已经编写了一些代码，可以在Google云端硬盘中成功上传图片，但是我需要在运行此项目并在浏览器中获取代码后，在浏览器中复制授权代码。我需要在控制台中复制此代码，然后才能正常工作。

但我正在尝试制作用于上传图片的批处理文件，因此不希望这些手动工作。请帮我。提前谢谢。

这是我的代码：

/**
 * 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());

首次运行应用时，您只需要完成授权流程。然后，您可以存储刷新令牌并使用它来构建授权请求所需的凭据对象。刷新令牌持续到用户手动撤销为止。

如何在java中编写批处理程序以在Google云端硬盘中上传文件？
