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

## Создание вашей собственной модели

После этого вы описываете вашу модель данных как класс, наследующий от `BaseModel`.

Используйте аннотации типов Python для всех атрибутов:

```Python hl_lines="7-11"
{!../../docs_src/body/tutorial001.py!}
```

{* ../../docs_src/first_steps/tutorial001.py hl[7] *}

This is a Python function.

It will be called by **FastAPI** whenever it receives a request to the URL "`/`" using a `GET` operation.

In this case, it is an `async` function.

---

You could also define it as a normal function instead of `async def`:

{* ../../docs_src/first_steps/tutorial003.py hl[7] *}

/// note

```Python hl_lines="7"
{!../../docs_src/first_steps/tutorial003.py!}
```

/// note

Jeśli nie znasz różnicy, sprawdź [Async: *"In a hurry?"*](../async.md#in-a-hurry){.internal-link target=_blank}.

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

```Python hl_lines="13  15"
{!../../docs_src/custom_request_and_route/tutorial002.py!}
```

If an exception occurs, the`Request` instance will still be in scope, so we can read and make use of the request body when handling the error:

```Python hl_lines="16-18"
{!../../docs_src/custom_request_and_route/tutorial002.py!}
```

## Custom `APIRoute` class in a router

在生产环境中，您应该选择上述任一选项。

但这是一种专注于 WebSockets 的服务器端并提供一个工作示例的最简单方式：

```Python hl_lines="2  6-38  41-43"
{!../../docs_src/websockets/tutorial001.py!}
```

## 创建 `websocket`

在您的 **FastAPI** 应用程序中，创建一个 `websocket`：

```Python hl_lines="1  46-47"
{!../../docs_src/websockets/tutorial001.py!}
```

/// note | "技术细节"

您也可以使用 `from starlette.websockets import WebSocket`。

```Python hl_lines="7"
{!../../docs_src/first_steps/tutorial003.py!}
```

/// note

Nếu bạn không biết sự khác nhau, kiểm tra [Async: *"Trong khi vội vàng?"*](../async.md#in-a-hurry){.internal-link target=_blank}.

### Bước 5: Nội dung trả về

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

간단한 예제부터 시작해봅시다:

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

이 프로그램을 실행한 결과값:

```
John Doe
```

함수는 아래와 같이 실행됩니다:

* `first_name`과 `last_name`를 받습니다.
* `title()`로 각 첫 문자를 대문자로 변환시킵니다.
* 두 단어를 중간에 공백을 두고 <abbr title="두 개를 하나로 차례차례 이어지게 하다">연결</abbr>합니다.

```Python hl_lines="2"
{!../../docs_src/python_types/tutorial001.py!}
```

### 코드 수정

이건 매우 간단한 프로그램입니다.

```Python hl_lines="3  6-8"
{!../../docs_src/sub_applications/tutorial001.py!}
```

### Unteranwendung

Erstellen Sie dann Ihre Unteranwendung und deren *Pfadoperationen*.

Diese Unteranwendung ist nur eine weitere Standard-FastAPI-Anwendung, aber diese wird „gemountet“:

```Python hl_lines="11  14-16"
{!../../docs_src/sub_applications/tutorial001.py!}
```

### Die Unteranwendung mounten

//// tab | Python 3.8+ без Annotated

/// tip | "Подсказка"

Рекомендуется использовать версию с `Annotated` если возможно.

///

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

////

/// info | "Информация"

Поддержка `Annotated` была добавлена в FastAPI начиная с версии 0.95.0 (и с этой версии рекомендуется использовать этот подход).

En este caso tendrías que asegurarte de que sea único para cada operación.

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