java - 通过 Google API 访问电子表格 invalid_grant

Question

我创建了一个 google 表单，并将表单结果保存在一个名为 yht_istekler. 的 excell 表中我正在使用以下代码片段。取自 Create Spreadsheet using Google Spreadsheet API in Google drive in Java虽然我收到以下错误，但我做错了什么？

  List<TrenSeferScheduleEvent> trenSeferScheduleEventList = new ArrayList<TrenSeferScheduleEvent>();

  URL SPREADSHEET_FEED_URL;
  SPREADSHEET_FEED_URL = new URL("https://spreadsheets.google.com/feeds/spreadsheets/private/full");

  File p12 = new File("./conf/key.p12");

  HttpTransport httpTransport = new NetHttpTransport();
  JacksonFactory jsonFactory = new JacksonFactory();
  List<String> SCOPES_ARRAY = Arrays.asList("https://spreadsheets.google.com/feeds", "https://spreadsheets.google.com/feeds/spreadsheets/private/full", "https://docs.google.com/feeds");
  GoogleCredential credential = new GoogleCredential.Builder()
          .setTransport(httpTransport)
          .setJsonFactory(jsonFactory)
          .setServiceAccountId("clientID")
          .setServiceAccountScopes(SCOPES_ARRAY)
          .setServiceAccountPrivateKeyFromP12File(p12)
          .build();

  SpreadsheetService service = new SpreadsheetService("yht_istekleri");
  service.setOAuth2Credentials(credential);

错误:

尝试将值为 offline 的 access_type 添加到您的授权请求中。

不到 2 天前，我遇到了一个与此非常相似的错误，这解决了问题。

此外，只是为了确认 clientID 值应该类似于 @developer.gserviceaccount.com他们基本上期望来自控制台 api 凭据的 email_address 值 - 而不是 client_id
