無效的OAuth2令牌GAE/GWT的Java應用程序

我開發上按一下按鈕的GWT/GAE的Java應用程序，它無效的OAuth2令牌GAE/GWT的Java應用程序

只需通過GWT地理位置實現獲取用戶的位置（工作得很好）
應該寫緯度，經度和精確度爲谷歌電子表格

當我點擊「保存到電子表格」按鈕，我收到以下錯誤消息在我的Eclipse控制檯：

所以它必須是憑證/令牌的問題。

這裏是服務器端RPC服務代碼：

public class GSpreadsheetServiceImpl extends RemoteServiceServlet implements 
     GSpreadsheetService { 

    @Override 
    public void insertRow(String latitude, String longitude, String accuracy) { 

     try { 
      String userId = UserServiceFactory.getUserService().getCurrentUser().getUserId(); 
      Credential credential = OAuth2Utils.initializeFlow().loadCredential(userId); 

      SpreadsheetService service = new SpreadsheetService("Locator-v1"); 

      service.setOAuth2Credentials(credential); 

      // Define the URL to request. This should never change. 
      URL SPREADSHEET_FEED_URL = new URL(
       "https://spreadsheets.google.com/feeds/spreadsheets/private/full"); 

      // Make a request to the API and get all spreadsheets. 
      SpreadsheetFeed feed = service.getFeed(SPREADSHEET_FEED_URL, 
       SpreadsheetFeed.class); 
      List<SpreadsheetEntry> spreadsheets = feed.getEntries(); 

      // TODO: Choose a spreadsheet more intelligently based on your 
      // app's needs. 
      SpreadsheetEntry spreadsheet = spreadsheets.get(0); 
      for (SpreadsheetEntry spreadsheetEntry : spreadsheets) { 
       if (spreadsheetEntry.getKey() == "MY_SPREADSHEET_KEY") { 
        spreadsheet = spreadsheetEntry; 
        break; 
       } 
      } 

      // Get the first worksheet of the first spreadsheet. 
      // TODO: Choose a worksheet more intelligently based on your 
      // app's needs. 
      WorksheetFeed worksheetFeed = service.getFeed(
       spreadsheet.getWorksheetFeedUrl(), WorksheetFeed.class); 
      List<WorksheetEntry> worksheets = worksheetFeed.getEntries(); 
      WorksheetEntry worksheet = worksheets.get(0); 

      // Fetch the list feed of the worksheet. 
      URL listFeedUrl = worksheet.getListFeedUrl(); 
      ListFeed listFeed = service.getFeed(listFeedUrl, ListFeed.class); 

      // Create a local representation of the new row. 
      ListEntry row = new ListEntry(); 
      row.getCustomElements().setValueLocal("Latitude", latitude); 
      row.getCustomElements().setValueLocal("Longitude", longitude); 
      row.getCustomElements().setValueLocal("Accuracy", accuracy); 

      // Send the new row to the API for insertion. 
      row = service.insert(listFeedUrl, row); 
     } catch (ServiceException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     } catch (MalformedURLException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     } catch (IOException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     } 

    } 

}

這裏是OAuth2Utils類：

public class OAuth2Utils { 
    /** Global instance of the HTTP transport. */ 
    static final HttpTransport HTTP_TRANSPORT = new UrlFetchTransport(); 

    /** Global instance of the JSON factory. */ 
    static final JsonFactory JSON_FACTORY = new JacksonFactory(); 

    static String getRedirectUri(HttpServletRequest req) { 
     GenericUrl url = new GenericUrl(req.getRequestURL().toString()); 
     url.setRawPath("/oauth2callback"); 
     return url.build(); 
    } 

    static GoogleAuthorizationCodeFlow initializeFlow() throws IOException { 
     return new GoogleAuthorizationCodeFlow.Builder(HTTP_TRANSPORT, 
       JSON_FACTORY, "MY_CLIENT_ID", 
       "MY_KEY", 
       Collections.singleton("https://spreadsheets.google.com/feeds/")) 
       .setCredentialStore(new AppEngineCredentialStore()) 
       .setAccessType("offline").build(); 
    } 
}

有誰知道這個問題可能是什麼？

最好的問候，

這樣工作的：

1）使用谷歌驅動DrEdit例如對OAuth的https://developers.google.com/drive/examples/java

注意：您需要添加刷新令牌，我發現增加它並不難。

2）連接是這樣的：

SpreadsheetService service = new SpreadsheetService("cellmaster-v0.2"); 

    // Authorize the service object for a specific user (see other sections) 
    service.setHeader("Authorization", "Bearer " + accessToken); 


    URL SPREADSHEET_FEED_URL = getSpreadsheetUrl(spreadsheetKey); 
    spreadsheet = service.getEntry 
      (SPREADSHEET_FEED_URL, SpreadsheetEntry.class);

我看了很多例子。我花了幾天才找到這個解決方案。
