Question

在我的网络服务中，我必须验证用户是否拥有youtube频道。

在我的Web服务中，我具有以下信息：

GoogleIdToken：通过我的客户端应用程序上的Google OAuth2同意屏幕。

我想获取不带OAuth2的Google帐户的Youtube频道，因为我将在后端进行操作，因此无法向用户显示GoogleOAuth2同意屏幕。

我检查了documentation，但是所有通道方法都使用OAuth2。

如果我将idToken与list (my channel)方法一起使用，那就太完美了。

这是我的授权码：

@Component
@RequiredArgsConstructor
public class YoutubeDataApiVerifier {

    private static final String CLIENT_SECRETS= "client_secret.json";
    private static final Collection<String> SCOPES =
            Arrays.asList("https://www.googleapis.com/auth/youtube.readonly");

    private static final String APPLICATION_NAME = "Fame Things";
    private static final JsonFactory JSON_FACTORY = JacksonFactory.getDefaultInstance();

    /**
     * Create an authorized Credential object.
     *
     * @return an authorized Credential object.
     * @throws IOException
     */
    public Credential authorize(final NetHttpTransport httpTransport, GoogleIdToken idToken, String token) throws Exception {
        File file = ResourceUtils.getFile("classpath:" + CLIENT_SECRETS);
        InputStream in = new FileInputStream(file);
        GoogleClientSecrets clientSecrets =
                GoogleClientSecrets.load(JSON_FACTORY, new InputStreamReader(in));
        // Build flow and trigger user authorization request.
        GoogleAuthorizationCodeFlow flow =
                new GoogleAuthorizationCodeFlow.Builder(httpTransport, JSON_FACTORY, clientSecrets, SCOPES)
                        .build();
        /**
         * ***************************************************************
         * This line prints a Google OAuth2 Consent Screen to the console.
         * But  the user already authorized at client app and I send googleId token to the backend.
         * It should give me the credentials without consent screen but I am missing something.
         */
        Credential credential =
                new AuthorizationCodeInstalledApp(flow, new LocalServerReceiver()).authorize(token);
        return credential;
    }

    /**
     * Build and return an authorized API client service.
     *
     * @return an authorized API client service
     * @throws GeneralSecurityException, IOException
     */
    public YouTube getService(GoogleIdToken idToken, String token) throws Exception {
        final NetHttpTransport httpTransport = GoogleNetHttpTransport.newTrustedTransport();
        Credential credential = authorize(httpTransport, idToken, token);
        return new YouTube.Builder(httpTransport, JSON_FACTORY, credential)
                .setApplicationName(APPLICATION_NAME)
                .build();
    }


    public String getMyChannel(GoogleIdToken idToken, String token) throws Exception {
        YouTube youtubeService = getService(idToken, token);
        // Define and execute the API request
        YouTube.Channels.List request = youtubeService.channels()
                .list("snippet,contentDetails,statistics");
        ChannelListResponse response = request.setMine(true).execute();
        return response.toPrettyString();
    }
}

问题出在这一行：

Credential credential =
        new AuthorizationCodeInstalledApp(flow, new LocalServerReceiver()).authorize(token);

我在后端有GoogleIdToken，可以用它获取凭据吗？

使用googleIdToken获取YouTube频道信息
