YouTube API - Oauth2 Flow（OSGI Bundle）

我在Apache Felix上开发了一个OSGI Bundle . 该套件公开了不同的API来管理YouTube直播活动 . 捆绑服务将通过REST服务公开，并由具有Web浏览器（chrome，safari，mozilla）的用户使用 .

我为帐户生成凭据谷歌（client_secret和client_id）并将其保存在文件中，然后我的代码使用此凭据并正常工作 .

我使用这个类（在youtube docs上找到）进行身份验证：

public static Credential authorize(List<String> scopes, String credentialDatastore) throws IOException {

    // Load client secrets.
    Reader clientSecretReader = new InputStreamReader(Auth.class.getResourceAsStream("/client_secrets.json"));
    GoogleClientSecrets clientSecrets = GoogleClientSecrets.load(JSON_FACTORY, clientSecretReader);

    // Checks that the defaults have been replaced (Default = "Enter X here").
    if (clientSecrets.getDetails().getClientId().startsWith("Enter")
            || clientSecrets.getDetails().getClientSecret().startsWith("Enter ")) {
        LOGGER.info(
                "Enter Client ID and Secret from https://console.developers.google.com/project/_/apiui/credential "
                        + "into src/main/resources/client_secrets.json");
        System.exit(1);
    }

    // This creates the credentials datastore at ~/.oauth-credentials/${credentialDatastore}
    FileDataStoreFactory fileDataStoreFactory = new FileDataStoreFactory(new File(System.getProperty("user.home") + "/" + CREDENTIALS_DIRECTORY));
    DataStore<StoredCredential> datastore = fileDataStoreFactory.getDataStore(credentialDatastore);

    GoogleAuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow.Builder(
            HTTP_TRANSPORT, JSON_FACTORY, clientSecrets, scopes).setCredentialDataStore(datastore)
            .build();

    // Build the local server and bind it to port 8080
    LocalServerReceiver localReceiver = new LocalServerReceiver.Builder().setPort(8080).build();

    // Authorize.
    return new AuthorizationCodeInstalledApp(flow, localReceiver).authorize("myUsername");
}

首次使用日志我发现：

请在浏览器中打开以下地址：https：//accounts.google.com/o/oauth2/auth？client_id = my_client_id＆redirect_uri = http：//localhost：8080 / Callback＆response_type = code＆scope = https://www.googleapis . COM / auth /中的YouTube

直到我没有在浏览器中输入此URL，才会阻止身份验证过程 . 键入并单击后，该过程正常 .

我的问题是：

当用户使用从浏览器调用此服务（api REST将包装此服务）时，在身份验证过程中阻止调用，直到输入和调用url https://accounts.google.com/o/oauth2/auth?client_id=my_client_id&redirect_uri=http://localhost:8080/Callback&response_type=code&scope=https://www.googleapis.com/auth/youtube，如何通知客户端？

我想要对客户端进行透明身份验证 . 身份验证过程必须只涉及服务器，确切地说是OSGI捆绑包 .
