GWT/GAE Java アプリケーションを開発しています。

  1. GWT 地理位置情報の実装を介してユーザーの位置を取得するだけです (非常にうまく機能します)。
  2. ボタンをクリックすると、緯度、経度、精度が Google スプレッドシートに書き込まれます。

[スプレッドシートに保存] ボタンをクリックすると、Eclipse コンソールに次のエラー メッセージが表示されます。

したがって、資格情報/トークンに問題があるはずです。

サーバー側の RPC サービス コードは次のとおりです。

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();
        }

    }

}

OAuth2Utils クラスは次のとおりです。

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();
    }
}

問題が何であるかを誰かが知っていますか？

よろしくお願いします、

この方法は機能します：

1) OAuth https://developers.google.com/drive/examples/javaに Google ドライブ DrEdit の例を使用する

注: リフレッシュ トークンを追加する必要があります。追加するのは難しくないことがわかりました。

2) 次のように接続します。

    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);

たくさんの例を見ました。この解決策を見つけるのに数日かかりました。
