## Добавление фоновой задачи

Внутри функции вызовите метод `.add_task()` у объекта *background tasks* и передайте ему функцию, которую хотите выполнить в фоне:

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

`.add_task()` принимает следующие аргументы:

## `HTTPException` verwenden

Um HTTP-Responses mit Fehlern zum Client zurückzugeben, verwenden Sie `HTTPException`.

### `HTTPException` importieren

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

### Eine `HTTPException` in Ihrem Code auslösen

# Erste Schritte

Die einfachste FastAPI-Datei könnte wie folgt aussehen:

```Python
{!../../docs_src/first_steps/tutorial001.py!}
```

Kopieren Sie dies in eine Datei `main.py`.

Starten Sie den Live-Server:

<div class="termy">

```console
$ uvicorn main:app --reload

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)

```Python hl_lines="14"

```

이는 `tags`를 항목 리스트로 만듭니다. 각 항목의 타입을 선언하지 않더라도요.

## 타입 매개변수가 있는 리스트 필드

하지만 파이썬은 내부의 타입이나 "타입 매개변수"를 선언할 수 있는 특정 방법이 있습니다:

### typing의 `List` 임포트

먼저, 파이썬 표준 `typing` 모듈에서 `List`를 임포트합니다:

```Python hl_lines="1"
{!../../docs_src/body_nested_models/tutorial002.py!}
```

### 타입 매개변수로 `List` 선언

## 导入 `File` 与 `Form`

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

## 定义 `File` 与 `Form` 参数

创建文件和表单参数的方式与 `Body` 和 `Query` 一样：

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

文件和表单字段作为表单数据上传与接收。

声明文件可以使用 `bytes` 或 `UploadFile` 。
