# Ek Status Code'ları { #additional-status-codes }

Varsayılan olarak **FastAPI**, response'ları bir `JSONResponse` kullanarak döndürür; *path operation*'ınızdan döndürdüğünüz içeriği bu `JSONResponse`'un içine yerleştirir.

Varsayılan status code'u veya *path operation* içinde sizin belirlediğiniz status code'u kullanır.

## Ek status code'ları { #additional-status-codes_1 }

   * instance, so it can be invoked again to create multiple independent maps.
   *
   * <p>The bulk operations {@code putAll}, {@code equals}, and {@code clear} are not guaranteed to
   * be performed atomically on the returned map. Additionally, {@code size} and {@code
   * containsValue} are implemented as bulk read operations, and thus may fail to observe concurrent
   * writes.
   *

   *
   * <p><b>Performance note:</b> This method will sometimes recognize that the actual copy operation
   * is unnecessary; for example, {@code copyOf(copyOf(anArrayList))} will copy the data only once.
   * This reduces the expense of habitually making defensive copies at API boundaries. However, the
   * precise conditions for skipping the copy operation are undefined.
   *
   * @throws NullPointerException if any of {@code elements} is null

## `BackgroundTasks` の使用 { #using-backgroundtasks }

まず初めに、`BackgroundTasks` をインポートし、`BackgroundTasks` の型宣言と共に、*path operation function* のパラメーターを定義します:

{* ../../docs_src/background_tasks/tutorial001_py310.py hl[1,13] *}

**FastAPI** は、`BackgroundTasks` 型のオブジェクトを作成し、そのパラメーターに渡します。
