谷歌OAuth2 Java代码每次都询问权限

Question

我将以下代码与google-client-secret.json文件一起使用，并尝试将其作为eclipse中的java应用程序运行。我想存储权限，这样一旦我接受了权限，它就不会再询问了。现在，它每次都在提示。在那之后，一切都像预期的那样工作，并写入我的google工作表。

    public static Credential authorizeSHEETS() throws IOException, GeneralSecurityException {
        File fileIn = new File("src/jg/sos/orders/google-sheets-client-secret.json");
//        InputStream in = GoogleAuthorizeUtil.class.getResourceAsStream("src/jg/sos/orders/google-sheets-client-secret.json");
        InputStream in = new FileInputStream(fileIn);
        GoogleClientSecrets clientSecrets = GoogleClientSecrets.load(JacksonFactory.getDefaultInstance(), new InputStreamReader(in));

        List<String> scopes = Arrays.asList(SheetsScopes.SPREADSHEETS);

        GoogleAuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow.Builder(GoogleNetHttpTransport.newTrustedTransport(), JacksonFactory.getDefaultInstance(), clientSecrets, scopes).setDataStoreFactory(new MemoryDataStoreFactory())
                .setAccessType("offline").setApprovalPrompt("auto").build();
        Credential credential = new AuthorizationCodeInstalledApp(flow, new LocalServerReceiver()).authorize("user");

        return credential;
    }

有没有什么想法可以让它只在第一次提示我权限，然后下一次我运行它就不会了？

谢谢你的帮助！JJ

所以我找到了这个问题的答案，以防有人遇到这个问题。我改为使用服务帐户，并为其下载json文件并将其放入我的项目中。

然后我只是引用了它，并使用DataStoreFactory保存了令牌，如下所示：

public static Credential authorizeSHEETS() throws IOException, GeneralSecurityException {
            File fileIn = new File("src/jg/sos/orders/google-sheets-client-secret.json");
    //        InputStream in = GoogleAuthorizeUtil.class.getResourceAsStream("src/jg/sos/orders/google-sheets-client-secret.json");
            InputStream in = new FileInputStream(fileIn);
            GoogleClientSecrets clientSecrets = GoogleClientSecrets.load(JacksonFactory.getDefaultInstance(), new InputStreamReader(in));
    
            List<String> scopes = Arrays.asList(SheetsScopes.SPREADSHEETS);
            
            FileDataStoreFactory dataStoreFactory = new FileDataStoreFactory(new File("src/jg/sos/orders"));
    
            GoogleAuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow.Builder(GoogleNetHttpTransport.newTrustedTransport(), JacksonFactory.getDefaultInstance(), clientSecrets, scopes)
                    .setDataStoreFactory(dataStoreFactory)
                    .setAccessType("offline").setApprovalPrompt("auto").build();
            
            Credential credential = new AuthorizationCodeInstalledApp(flow, new LocalServerReceiver()).authorize("user");
            
            System.out.println("token" + credential.getAccessToken());
    
            return credential;
        }
