服务器端应用程序的Google OAuth 2.0

Question

我正尝试在cron作业中创建一个从shell脚本运行命令行的java应用程序。既然如此，我不会让用户在场表示同意允许在浏览器中进行访问。此应用程序将查询目录，并将此目录中的视频上传到YouTube。我对YouTube api和Oauth2.0也很陌生。在我所做的所有研究中，我看到了很多关于如何完成我想要做的事情的相互冲突的信息。

这里是我的代码。请让我知道你看到我出错的地方。提前致谢！

公共静态证书授权（名单范围，字符串credentialDatastore）抛出IOException异常{

// Load client secrets. 
    //Reader clientSecretReader = new InputStreamReader(Auth.class.getResourceAsStream("/main/resources/client_secrets.json")); 
    Reader clientSecretReader = new InputStreamReader(Auth.class.getResourceAsStream("/main/resources/client_secret_file.apps.googleusercontent.com.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 ")) { 
     System.out.println(
       "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} 
    // THIS IS WHERE I NEED TO CHANGE, TO WORK WITH THIS APP!!!! 
    // FileDataStoreFactory fileDataStoreFactory = new FileDataStoreFactory(new File(System.getProperty("user.home") + "/" + CREDENTIALS_DIRECTORY)); 
    FileDataStoreFactory fileDataStoreFactory = new FileDataStoreFactory(new File("." + "/" + CREDENTIALS_DIRECTORY)); 
    DataStore<StoredCredential> datastore = fileDataStoreFactory.getDataStore(credentialDatastore); 

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

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

    // Authorize. 
    try { 
     Credential returnCreds = new AuthorizationCodeInstalledApp(flow, localReceiver).authorize("xxxxxxxxxxxxxxxxxxx"); 
     returnCreds.refreshToken(); 

     return returnCreds; 
    } catch (Exception e) { 
     // TODO Auto-generated catch block 
     e.printStackTrace(); 
    } 
    // if not authorized, will return a null credential 
    return null; 
}

它看起来非常像这次调职，很多东西，我问：

Does Google OAuth2.0 support an OAuth-flow for a Resource Owner Password Credential Flow?

仍还没有完成这个实现，但它确实看起来像一个很好的领导！
