Übergeben Sie innerhalb Ihrer *Pfadoperation-Funktion* Ihre Taskfunktion mit der Methode `.add_task()` an das *Hintergrundtasks*-Objekt:

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

`.add_task()` erhält als Argumente:

* Eine Taskfunktion, die im Hintergrund ausgeführt wird (`write_notification`).

        dummyRus.buffer = new short[] { 'T', 'e', 's', 't', 'i', 'n', 'g' };
        dummyRus.length = 14; // 7 characters * 2 bytes/char
        dummyRus.maximum_length = 14;
        UnicodeString manualUnicodeString = new UnicodeString(dummyRus, false);
        assertEquals("Testing", manualUnicodeString.toString(), "toString should work with manually set buffer and length (no zterm)");

## 添加后台任务

在你的 *路径操作函数* 里，用 `.add_task()` 方法将任务函数传到 *后台任务* 对象中：

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

`.add_task()` 接收以下参数：

* 在后台运行的任务函数(`write_notification`)。
* 应按顺序传递给任务函数的任意参数序列(`email`)。
* 应传递给任务函数的任意关键字参数(`message="some notification"`)。

### Modell für Eingabe { #model-for-input }

Wenn Sie dieses Modell wie hier als Eingabe verwenden:

{* ../../docs_src/separate_openapi_schemas/tutorial001_py310.py ln[1:15] hl[14] *}

... dann ist das Feld `description` **nicht erforderlich**. Weil es den Defaultwert `None` hat.
