## Adicionar a tarefa em segundo plano

Dentro de sua _função de operação de caminho_, passe sua função de tarefa para o objeto _tarefas em segundo plano_ com o método `.add_task()`:

```Python hl_lines="14"
{!../../docs_src/background_tasks/tutorial001.py!}
```

`.add_task()` recebe como argumentos:

//// tab | Python 3.8+ nicht annotiert

/// tip | "Tipp"

Bevorzugen Sie die `Annotated`-Version, falls möglich.

///

```Python hl_lines="1"
{!> ../../docs_src/request_forms_and_files/tutorial001.py!}
```

////

## `File` und `Form`-Parameter definieren

Erstellen Sie Datei- und Formularparameter, so wie Sie es auch mit `Body` und `Query` machen würden:

//// tab | Python 3.9+

```Python hl_lines="17  22  27"
{!../../docs_src/path_operation_configuration/tutorial002.py!}
```

OpenAPI 概图会自动添加标签，供 API 文档接口使用：

<img src="/img/tutorial/path-operation-configuration/image01.png">

## `summary` 和 `description` 参数

路径装饰器还支持 `summary` 和 `description` 这两个参数：

```Python hl_lines="20-21"
{!../../docs_src/path_operation_configuration/tutorial003.py!}
```

## 文档字符串（`docstring`）

```

////

//// tab | Python 3.8+ non-Annotated

/// tip | Dica

Prefira utilizar a versão `Annotated` se possível.

///

```Python hl_lines="3"
{!> ../../docs_src/cookie_params/tutorial001.py!}
```

////

## Declare parâmetros de `Cookie`

Então declare os paramêtros de cookie usando a mesma estrutura que em `Path` e `Query`.

Um diese zu deaktivieren, setzen Sie deren URLs beim Erstellen Ihrer `FastAPI`-App auf `None`:

```Python hl_lines="8"
{!../../docs_src/custom_docs_ui/tutorial001.py!}
```

### Die benutzerdefinierten Dokumentationen hinzufügen

Jetzt können Sie die *Pfadoperationen* für die benutzerdefinierten Dokumentationen erstellen.

```

////

//// tab | Python 3.8+ non-Annotated

/// tip

Prefer to use the `Annotated` version if possible.

///

```Python hl_lines="1"
{!> ../../docs_src/request_forms_and_files/tutorial001.py!}
```

////

## Define `File` and `Form` parameters

Create file and form parameters the same way you would for `Body` or `Query`:

//// tab | Python 3.9+

```Python hl_lines="10-12"

```Python hl_lines="4"
{!../../docs_src/body_fields/tutorial001.py!}
```

/// warning | "Aviso"

Note que `Field` é importado diretamente do `pydantic`, não do `fastapi` como todo o resto (`Query`, `Path`, `Body`, etc).

///

## Declare atributos do modelo

Você pode então utilizar `Field` com atributos do modelo:

```Python hl_lines="11-14"
{!../../docs_src/body_fields/tutorial001.py!}
```

Vous devez vous assurer qu'il est unique pour chaque opération.

```Python hl_lines="6"
{!../../docs_src/path_operation_advanced_configuration/tutorial001.py!}
```
