如何延长 Oauth 2 StoredCredential 的持续时间

Question

我正在制作一个 API 来获取 google sheet 的内容，但是每隔一小时，令牌“StoredCredential”就会过期，所以我必须使用 UI（您选择 google 帐户的菜单），我如何才能延长令牌的使用寿命，因为该程序每天都会启动，我不想每次都输入我的 google 帐户天？
我已经尝试更改过期时间，但没有用

这是我的实际代码：

    private static final JsonFactory JSON_FACTORY = JacksonFactory.getDefaultInstance();
    
    private static final String TOKENS_DIRECTORY_PATH = "u:\tokens";

    private static final List<String> SCOPES =
            Arrays.asList(SheetsScopes.SPREADSHEETS,SheetsScopes.DRIVE);

    private static final String CREDENTIALS_FILE_PATH = "credentials.json";

    private static Credential getCredentials(final NetHttpTransport HTTP_TRANSPORT) throws Exception {
        // Load client secrets.
        InputStream in = new FileInputStream(CREDENTIALS_FILE_PATH);
        if (in == null) {
            throw new FileNotFoundException("Resource not found: " + CREDENTIALS_FILE_PATH);
        }
        GoogleClientSecrets clientSecrets = GoogleClientSecrets.load(JSON_FACTORY, new InputStreamReader(in));
        
          FileDataStoreFactory fileDataStoreFactory = new FileDataStoreFactory(new File(TOKENS_DIRECTORY_PATH));
              DataStore<StoredCredential> datastore = fileDataStoreFactory.getDataStore("StoredCredential");
              datastore.values().forEach(x -> x.setExpirationTimeMilliseconds((long) 999999999));
              //DEBUG
              datastore.values().forEach(x -> System.out.println(x.getExpirationTimeMilliseconds()));
              
        // Build flow and trigger user authorization request.
        GoogleAuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow.Builder(
                HTTP_TRANSPORT, JSON_FACTORY, clientSecrets, SCOPES)
                //.setDataStoreFactory(new FileDataStoreFactory(new java.io.File(TOKENS_DIRECTORY_PATH)))
                .setCredentialDataStore(datastore)
                .setAccessType("online")
                .setApprovalPrompt(null)
                .build();
        LocalServerReceiver receiver = new LocalServerReceiver.Builder().setPort(8888).build();
        
        return new AuthorizationCodeInstalledApp(flow, receiver).authorize("user");
    }

阅读我的其他问题的文档后，我找到了延长 StoredCredential 文件生命周期的方法，您需要将访问类型从在线更改为离线。

更正版本：

 private static final JsonFactory JSON_FACTORY = JacksonFactory.getDefaultInstance();
    
    private static final String TOKENS_DIRECTORY_PATH = "u:\tokens";

    private static final List<String> SCOPES =
            Arrays.asList(SheetsScopes.SPREADSHEETS,SheetsScopes.DRIVE);

    private static final String CREDENTIALS_FILE_PATH = "credentials.json";

    private static Credential getCredentials(final NetHttpTransport HTTP_TRANSPORT) throws Exception {
        // Load client secrets.
        InputStream in = new FileInputStream(CREDENTIALS_FILE_PATH);
        if (in == null) {
            throw new FileNotFoundException("Resource not found: " + CREDENTIALS_FILE_PATH);
        }
        GoogleClientSecrets clientSecrets = GoogleClientSecrets.load(JSON_FACTORY, new InputStreamReader(in));
        
          FileDataStoreFactory fileDataStoreFactory = new FileDataStoreFactory(new File(TOKENS_DIRECTORY_PATH));
              DataStore<StoredCredential> datastore = fileDataStoreFactory.getDataStore("StoredCredential");
              datastore.values().forEach(x -> x.setExpirationTimeMilliseconds((long) 999999999));
              //DEBUG
              datastore.values().forEach(x -> System.out.println(x.getExpirationTimeMilliseconds()));
              
        // Build flow and trigger user authorization request.
        GoogleAuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow.Builder(
                HTTP_TRANSPORT, JSON_FACTORY, clientSecrets, SCOPES)
                //.setDataStoreFactory(new FileDataStoreFactory(new java.io.File(TOKENS_DIRECTORY_PATH)))
                .setCredentialDataStore(datastore)
                /* Here, we change the accessType */
                .setAccessType("offline")
                .setApprovalPrompt(null)
                .build();
        LocalServerReceiver receiver = new LocalServerReceiver.Builder().setPort(8888).build();
