我正在使用google的apis来创建一个小型桌面应用程序，以便上传视频更易于管理（我管理网络中心频道，长篇大论，为什么我需要这个）。我已经按照谷歌的指南来获得一个起点，但使用oauth2的身份验证失败，并显示以下控制台输出：

我在很多地方看到过这个问题，但没有可行的解决方案。 Google表示通过抛出警告而不是IOExceptions来修复错误，但我仍然收到警告和IOExceptions。
以下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和秘密。
答案 0 :(得分：3)
问题出现在以下行中：
LocalServerReceiver localReceiver = new LocalServerReceiver.Builder().setPort(8080).build();
可能是另一个进程使用的端口8080 ......
确保运行命令：
netstat -an | grep 8080
之后搜索进程并将其杀死
