Inside of your *path operation function*, pass your task function to the *background tasks* object with the method `.add_task()`:

{* ../../docs_src/background_tasks/tutorial001_py39.py hl[14] *}

`.add_task()` receives as arguments:

* A task function to be run in the background (`write_notification`).
* Any sequence of arguments that should be passed to the task function in order (`email`).

Dentro da sua *função de operação de rota*, passe sua função de tarefa para o objeto de *tarefas em segundo plano* com o método `.add_task()`:

{* ../../docs_src/background_tasks/tutorial001_py39.py hl[14] *}

O `.add_task()` recebe como argumentos:

* Uma função de tarefa a ser executada em segundo plano (`write_notification`).
* Qualquer sequência de argumentos que deve ser passada para a função de tarefa na ordem (`email`).

        // Call the method
        int bytesRead = response.readBytesWireFormat(byteData, 0);

        // Assertions
        // readBytesWireFormat returns bytes processed up to null terminator
        assertEquals(14, bytesRead); // 8 bytes key + 6 bytes domain name
        assertArrayEquals(encryptionKey, serverData.encryptionKey);
        assertEquals("DOMAIN", serverData.oemDomainName);
    }

    @Test

    // Edge: releasing null must be a no-op without exceptions
    @Test
    @DisplayName("releaseBuffer(null) is a no-op and does not throw")
    void releaseNullIsNoop() {
        BufferCacheImpl impl = new BufferCacheImpl(1, 4);
        assertDoesNotThrow(() -> impl.releaseBuffer(null));
        // Subsequent get should still work
        assertEquals(4, impl.getBuffer().length);
    }

        Name name = new Name(mockConfig, "\u0001MSBROWSE      ", 0x01, null);
        String result = name.toString();

        // Should replace first char with '..' and char at position 14 with '.'
        assertTrue(result.contains(".."));
        assertFalse(result.contains("\u0001"));
    }

    @Test
    void toString_withoutScope_shouldNotIncludeScope() {

## バックグラウンドタスクの追加

*path operations 関数* 内で、`.add_task()` メソッドを使用してタスク関数を *background tasks* オブジェクトに渡します。

{* ../../docs_src/background_tasks/tutorial001.py hl[14] *}

`.add_task()` は以下の引数を受け取ります:

* バックグラウンドで実行されるタスク関数 (`write_notification`)。
* タスク関数に順番に渡す必要のある引数の列 (`email`)。
* タスク関数に渡す必要のあるキーワード引数 (`message="some notification"`)。

## 依存性注入

그리고 두 모델 모두 대화형 API 문서에 사용됩니다:

## 응답 모델 인코딩 매개변수

응답 모델은 아래와 같이 기본값을 가질 수 있습니다:

{* ../../docs_src/response_model/tutorial004.py hl[11,13:14] *}

* `description: Optional[str] = None`은 기본값으로 `None`을 갖습니다.
* `tax: float = 10.5`는 기본값으로 `10.5`를 갖습니다.
* `tags: List[str] = []` 빈 리스트의 기본값으로: `[]`.

그러나 실제로 저장되지 않았을 경우 결과에서 값을 생략하고 싶을 수 있습니다.
