OpenAPIでは、以下のセキュリティスキームを定義しています:

* `apiKey`: アプリケーション固有のキーで、これらのものから取得できます。
    * クエリパラメータ
    * ヘッダー
    * クッキー
* `http`: 標準的なHTTP認証システムで、これらのものを含みます。
    * `bearer`: ヘッダ `Authorization` の値が `Bearer ` で、トークンが含まれます。これはOAuth2から継承しています。
    * HTTP Basic認証
    * HTTP ダイジェスト認証など
* `oauth2`: OAuth2のセキュリティ処理方法（「フロー」と呼ばれます）のすべて。
    * これらのフローのいくつかは、OAuth 2.0認証プロバイダ（Google、Facebook、X (Twitter)、GitHubなど）を構築するのに適しています。

**Solution**:
- Verify credentials: default is `admin`/`admin`
- Check if API is enabled in `system.properties`
- Use proper authentication header:
  ```bash
  curl -u admin:admin ...
  # or
  curl -H "Authorization: Basic YWRtaW46YWRtaW4=" ...
  ```

#### Issue: Large bulk imports timing out

**Solution**:
- Split large files into smaller batches (e.g., 10,000 docs per file)
- Increase timeout in `system.properties`:

import java.util.Date;

/**

    private Date logonTime;
    private Date logoffTime;

The simplicity of the dependency injection system makes **FastAPI** compatible with:

* all the relational databases
* NoSQL databases
* external packages
* external APIs
* authentication and authorization systems
* API usage monitoring systems
* response data injection systems
* etc.

   * This includes the HTTP method, headers, request body (if present), and URL.
   *
   * Example:
   *
   * ```
   * curl 'https://example.com/api' \
   *   -X PUT \
   *   -H 'Authorization: Bearer token' \
   *   --data '{\"key\":\"value\"}'

   * **Note:** This will consume the request body. This may have side effects if the [RequestBody]
   * is streaming or can be consumed only once.
