## Использование `StaticFiles`

* Импортируйте `StaticFiles`.
* "Примонтируйте" экземпляр `StaticFiles()` с указанием определенной директории.

```Python hl_lines="2  6"
{!../../docs_src/static_files/tutorial001.py!}
```

/// note | "Технические детали"

Вы также можете использовать `from starlette.staticfiles import StaticFiles`.

from fastapi.testclient import TestClient

from docs_src.additional_responses.tutorial001 import app

client = TestClient(app)


def test_path_operation():
    response = client.get("/items/foo")
    assert response.status_code == 200, response.text
    assert response.json() == {"id": "foo", "value": "there goes my hero"}


def test_path_operation_not_found():
    response = client.get("/items/bar")

Then set Cookies in it, and then return it:

```Python hl_lines="10-12"
{!../../docs_src/response_cookies/tutorial001.py!}
```

/// tip

Keep in mind that if you return a response directly instead of using the `Response` parameter, FastAPI will return it directly.

**FastAPI**将采用该模型，生成其`JSON Schema`并将其包含在`OpenAPI`中的正确位置。

例如，要声明另一个具有状态码 `404` 和`Pydantic`模型 `Message` 的响应，可以写：
```Python hl_lines="18  22"
{!../../docs_src/additional_responses/tutorial001.py!}
```

/// note

请记住，您必须直接返回 `JSONResponse` 。

///

/// info

`model` 密钥不是OpenAPI的一部分。
**FastAPI**将从那里获取`Pydantic`模型，生成` JSON Schema` ，并将其放在正确的位置。

## Вызов `uvicorn`

В вашем FastAPI приложении, импортируйте и вызовите `uvicorn` напрямую:

```Python hl_lines="1  15"
{!../../docs_src/debugging/tutorial001.py!}
```

### Описание `__name__ == "__main__"`

Главная цель использования `__name__ == "__main__"` в том, чтобы код выполнялся при запуске файла с помощью:

<div class="termy">

```console

Sie können problemlos dieselben Pydantic-Einstellungen verwenden, um Ihre generierte OpenAPI und die Dokumentationsoberflächen zu konfigurieren.

Zum Beispiel:

```Python hl_lines="6  11"
{!../../docs_src/conditional_openapi/tutorial001.py!}
```

Hier deklarieren wir die Einstellung `openapi_url` mit dem gleichen Defaultwert `"/openapi.json"`.

Und dann verwenden wir das beim Erstellen der `FastAPI`-App.

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

これらはOpenAPIスキーマに追加され、自動ドキュメントのインターフェースで使用されます:

## 概要と説明

`summary`と`description`を追加できます:

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