Youtube Data API v3 oAuth2 无法更改权限

Question

我正在使用 google 的 api 创建一个小型桌面应用程序，以使上传视频更易于管理（我管理一个网络集线器频道，关于我为什么需要它的长篇故事）。我已经按照 google 的指南获得了一个起点，但是使用 oauth2 的身份验证失败并显示以下控制台输出：

我在网上很多地方都看到过这个问题，但没有有效的解决方案。谷歌说这个错误是通过抛出警告而不是 IOExceptions 来修复的，但我仍然得到警告和 IOExceptions。

这是处理身份验证的代码：

public static final HttpTransport HTTP_TRANSPORT        = new NetHttpTransport();
public static final JsonFactory   JSON_FACTORY          = new JacksonFactory();
private static final String       CREDENTIALS_DIRECTORY = ".oauth-credentials";

public static Credential authorize(List<String> scopes, String credentialDatastore) throws IOException {
    Reader clientSecretReader = new InputStreamReader(AuthUtil.class.getResourceAsStream("/client_secrets.json"));
    GoogleClientSecrets clientSecrets = GoogleClientSecrets.load(JSON_FACTORY, clientSecretReader);
    System.out.println(clientSecrets.getDetails().getClientId());
    if (clientSecrets.getDetails().getClientId().startsWith("Enter")
            || clientSecrets.getDetails().getClientSecret().startsWith("Enter ")) {
        System.out.println(
                "Enter Client ID and Secret from https://code.google.com/apis/console/?api=youtube"
                        + "into src/main/resources/client_secrets.json");
        System.exit(1);
    }
    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();
    LocalServerReceiver localReceiver = new LocalServerReceiver.Builder().setPort(8080).build();

    return new AuthorizationCodeInstalledApp(flow, localReceiver).authorize("user");
}

是的，我已经替换了文件中的客户端 ID 和机密。

Answer 1

问题出现在行：

LocalServerReceiver localReceiver = new LocalServerReceiver.Builder().setPort(8080).build();

可能是 8080 端口被另一个进程使用...

确保运行命令：

netstat -an | grep 8080

然后搜索进程并杀死它
