尝试连接到 Google 云端硬盘时收到错误 400：redirect_uri_mismatch

Question

我在使用 Java 和 Maven 的 google Drive API 时遇到了问题。我已将drive-api添加到我在谷歌云上的项目以及我的代码库中，但每当我尝试使用默认代码连接时，我都会收到

Error 400: redirect_uri_mismatch

。

我尝试修改代码并查找谷歌文档，但没有任何运气。这是我的代码：

// Part of this code is taken from the Google Drive quickstart.
@UtilityClass
public class DriveQuickstart {
    private static final String APPLICATION_NAME = "default name";
    private static final JsonFactory JSON_FACTORY = GsonFactory.getDefaultInstance();
    private static final String TOKENS_DIRECTORY_PATH = "tokens";
    private static final List<String> SCOPES = Collections.singletonList(DriveScopes.DRIVE_METADATA_READONLY);
    private static final String CREDENTIALS_FILE_PATH = "/credentials.json"; //originally called client secret I believe

    private static Credential getCredentials(final NetHttpTransport HTTP_TRANSPORT) throws IOException {
        InputStream in = DriveQuickstart.class.getResourceAsStream(CREDENTIALS_FILE_PATH);
        if (in == null) {
            throw new FileNotFoundException("Resource not found: " + CREDENTIALS_FILE_PATH);
        }
        GoogleClientSecrets clientSecrets = GoogleClientSecrets.load(JSON_FACTORY, new InputStreamReader(in));

        GoogleAuthorizationCodeFlow flow =
                new GoogleAuthorizationCodeFlow.Builder(HTTP_TRANSPORT, JSON_FACTORY, clientSecrets, SCOPES)
                        .setDataStoreFactory(new FileDataStoreFactory(new java.io.File(TOKENS_DIRECTORY_PATH)))
                        .setAccessType("offline").build();
        LocalServerReceiver receiver = new LocalServerReceiver.Builder().setPort(8888).build();
        Credential credential = new AuthorizationCodeInstalledApp(flow, receiver).authorize("user");
        return credential;
    }

    public static void main(String... args) throws IOException, GeneralSecurityException {
        final NetHttpTransport HTTP_TRANSPORT = GoogleNetHttpTransport.newTrustedTransport();
        Drive service = new Drive.Builder(HTTP_TRANSPORT, JSON_FACTORY, getCredentials(HTTP_TRANSPORT))
                .setApplicationName(APPLICATION_NAME).build();
        Logger logger = Logger.getLogger("DriveQuickstart");

        FileList result = service.files().list().setPageSize(10).setFields("nextPageToken, files(id, name)").execute();
        List<File> files = result.getFiles();
        if (files == null || files.isEmpty()) {
            logger.warning("No files found.");
        } else {
            logger.warning("Files:");
            for (File file : files) {
                logger.warning(file.getName() + " (" + file.getId() + ")\n");
            }
        }
    }
}

这给了我：
