如何在java中使用批處理程序上傳文件到Google Drive？

Question

我寫了一些代碼，在Google驅動器中成功上傳圖片，但我需要將瀏覽器中的授權代碼複製到瀏覽器中，然後運行此項目並在瀏覽器中獲取代碼。我需要在控制檯中複製這段代碼，然後工作正常。

但我想爲批量文件上傳圖像，所以不要這些手動工作。 請幫幫我。 在此先感謝。

這裏是我的代碼：

/** 
* 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());

您只需通過授權流走你運行應用程序的第一次。然後，您可以存儲刷新令牌並使用它來構建授權請求所需的憑據對象。刷新令牌直到用戶手動撤銷。
