授权在本地工作但不托管

Question

这是我正在使用我的驱动器启用文件“credentials.json”进行项目OAuth 2.0身份验证的当前代码，这对本地项目工作正常，在我要使用此项目时停止工作。

public class GoogleDriveUtils { 

private static final String APPLICATION_NAME = "Google Drive API Java Quickstart";

private static final JsonFactory JSON_FACTORY = JacksonFactory.getDefaultInstance();

// Directory to store user credentials for this application.
private static final java.io.File CREDENTIALS_FOLDER //
        = new java.io.File("/tmp/");
private static final String CLIENT_SECRET_FILE_NAME = "credentials.json";

private static final List<String> SCOPES = Collections.singletonList(DriveScopes.DRIVE);

// Global instance of the {@link FileDataStoreFactory}.
private static FileDataStoreFactory DATA_STORE_FACTORY;

// Global instance of the HTTP transport.
private static HttpTransport HTTP_TRANSPORT;
private static Drive _driveService;
static {
    try {
        HTTP_TRANSPORT = GoogleNetHttpTransport.newTrustedTransport();
        DATA_STORE_FACTORY = new FileDataStoreFactory(CREDENTIALS_FOLDER);
    } catch (Throwable t) {
        t.printStackTrace();
        System.exit(1);
    }
}
public static Credential getCredentials() throws IOException {
    java.io.File clientSecretFilePath = new java.io.File(CREDENTIALS_FOLDER, CLIENT_SECRET_FILE_NAME);
   if (!clientSecretFilePath.exists()) {
        throw new FileNotFoundException("Please copy " + CLIENT_SECRET_FILE_NAME //
                + " to folder: " + CREDENTIALS_FOLDER.getAbsolutePath());
    }
    InputStream in = new FileInputStream(clientSecretFilePath);
    GoogleClientSecrets clientSecrets = GoogleClientSecrets.load(JSON_FACTORY, new InputStreamReader(in));

    // Build flow and trigger user authorization request.
    GoogleAuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow.Builder(HTTP_TRANSPORT, JSON_FACTORY,
            clientSecrets, SCOPES).setDataStoreFactory(DATA_STORE_FACTORY).setAccessType("offline").build();
    Credential credential = new AuthorizationCodeInstalledApp(flow, new LocalServerReceiver()).authorize("user");
    return credential;
}

public static Drive getDriveService() throws IOException {
    if (_driveService != null) {
        return _driveService;
    }
    Credential credential = getCredentials();
    //
    _driveService = new Drive.Builder(HTTP_TRANSPORT, JSON_FACTORY, credential) //
            .setApplicationName(APPLICATION_NAME).build();
    return _driveService;
}

}

AuthorizationCodeInstalledApp

用于已安装的应用程序这意味着浏览器窗口将在运行代码的计算机上打开。如果您在Web服务器上托管它，那么它会尝试打开该计算机上的浏览器窗口。不在用户机器上。

你应该关注Web server applications

public class CalendarServletSample extends AbstractAuthorizationCodeServlet {

  @Override
  protected void doGet(HttpServletRequest request, HttpServletResponse response)
      throws IOException {
    // do stuff
  }

  @Override
  protected String getRedirectUri(HttpServletRequest req) throws ServletException, IOException {
    GenericUrl url = new GenericUrl(req.getRequestURL().toString());
    url.setRawPath("/oauth2callback");
    return url.build();
  }

  @Override
  protected AuthorizationCodeFlow initializeFlow() throws IOException {
    return new GoogleAuthorizationCodeFlow.Builder(
        new NetHttpTransport(), JacksonFactory.getDefaultInstance(),
        "[[ENTER YOUR CLIENT ID]]", "[[ENTER YOUR CLIENT SECRET]]",
        Collections.singleton(CalendarScopes.CALENDAR)).setDataStoreFactory(
        DATA_STORE_FACTORY).setAccessType("offline").build();
  }

  @Override
  protected String getUserId(HttpServletRequest req) throws ServletException, IOException {
    // return user ID
  }
}

public class CalendarServletCallbackSample extends AbstractAuthorizationCodeCallbackServlet {

  @Override
  protected void onSuccess(HttpServletRequest req, HttpServletResponse resp, Credential credential)
      throws ServletException, IOException {
    resp.sendRedirect("/");
  }

  @Override
  protected void onError(
      HttpServletRequest req, HttpServletResponse resp, AuthorizationCodeResponseUrl errorResponse)
      throws ServletException, IOException {
    // handle error
  }

  @Override
  protected String getRedirectUri(HttpServletRequest req) throws ServletException, IOException {
    GenericUrl url = new GenericUrl(req.getRequestURL().toString());
    url.setRawPath("/oauth2callback");
    return url.build();
  }

  @Override
  protected AuthorizationCodeFlow initializeFlow() throws IOException {
    return new GoogleAuthorizationCodeFlow.Builder(
        new NetHttpTransport(), JacksonFactory.getDefaultInstance()
        "[[ENTER YOUR CLIENT ID]]", "[[ENTER YOUR CLIENT SECRET]]",
        Collections.singleton(CalendarScopes.CALENDAR)).setDataStoreFactory(
        DATA_STORE_FACTORY).setAccessType("offline").build();
  }

  @Override
  protected String getUserId(HttpServletRequest req) throws ServletException, IOException {
    // return user ID
  }
}
