Erstellen Sie eine Response wie in [Eine Response direkt zurückgeben](response-directly.md){.internal-link target=_blank} beschrieben und übergeben Sie die Header als zusätzlichen Parameter:

{* ../../docs_src/response_headers/tutorial001.py hl[10:12] *}

/// note | Technische Details

Sie können auch `from starlette.responses import Response` oder `from starlette.responses import JSONResponse` verwenden.

        assertVersionOlder("1.0-SNAPSHOT-SNAPSHOT", "1.0-SNAPSHOT");
        assertVersionOlder("1.0-alpha-1-SNAPSHOT-SNAPSHOT", "1.0-alpha-1-SNAPSHOT");

        assertVersionOlder("1.0-SNAPSHOT", "1.0-1-SNAPSHOT");
        assertVersionOlder("1.0-1-SNAPSHOT", "1.0-2-SNAPSHOT");
        // assertVersionEqual( "2.0-0-SNAPSHOT", "2.0-SNAPSHOT" );
        assertVersionOlder("2.0-SNAPSHOT", "2.0-1-SNAPSHOT");

Create a response as described in [Return a Response Directly](response-directly.md){.internal-link target=_blank} and pass the headers as an additional parameter:

{* ../../docs_src/response_headers/tutorial001.py hl[10:12] *}

/// note | Technical Details

You could also use `from starlette.responses import Response` or `from starlette.responses import JSONResponse`.

    // separate above
    expected =
        assertThrows(
            IllegalArgumentException.class, () -> range.intersection(Range.closed(10, 12)));
    assertThat(expected).hasMessageThat().contains("connected");
  }

  public void testGap_overlapping() {
    Range<Integer> range = Range.closedOpen(3, 5);

Importieren Sie zunächst `BackgroundTasks` und definieren Sie einen Parameter in Ihrer *Pfadoperation-Funktion* mit der Typdeklaration `BackgroundTasks`:

{* ../../docs_src/background_tasks/tutorial001.py hl[1,13] *}

**FastAPI** erstellt für Sie das Objekt vom Typ `BackgroundTasks` und übergibt es als diesen Parameter.

## Eine Taskfunktion erstellen

Erstellen Sie eine Funktion, die als Hintergrundtask ausgeführt werden soll.

        in 5..7 -> {
          data.writeByte('\n'.code) // 'data' on a line of its own.
        }

        in 8..9 -> {
          id = source.readUtf8LineStrict().takeIf { it.isNotEmpty() }
        }

        in 10..12 -> {
          id = null // 'id' on a line of its own.
        }

        in 13..14 -> {
          type = source.readUtf8LineStrict().takeIf { it.isNotEmpty() }
        }

        in 15..17 -> {

## `Response` 직접 반환하기

`Response`를 직접 반환할 때에도 헤더를 추가할 수 있습니다.

[응답을 직접 반환하기](response-directly.md){.internal-link target=_blank}에서 설명한 대로 응답을 생성하고, 헤더를 추가 매개변수로 전달하세요.

{* ../../docs_src/response_headers/tutorial001.py hl[10:12] *}

/// note | 기술적 세부사항

`from starlette.responses import Response`나 `from starlette.responses import JSONResponse`를 사용할 수도 있습니다.
