    As always, in FastAPI you can combine `def` and `async def` as needed.

    If you need a refresher about when to use which, check out the section _"In a hurry?"_ in the docs about [`async` and `await`](../async.md#in-a-hurry){.internal-link target=_blank}.

9. This *path operation function* is not returning dataclasses (although it could), but a list of dictionaries with internal data.

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

!!! note
    If you don't know the difference, check the [Async: *"In a hurry?"*](../async.md#in-a-hurry){.internal-link target=_blank}.

### Step 5: return the content

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

@app.get("/items/{item_id}")
async def read_item(item_id: int, q: Union[str, None] = None):
    return {"item_id": item_id, "q": q}
```

### Uruchom

Uruchom serwer używając:

<div class="termy">

```console

@app.get("/items/{item_id}")
async def read_item(item_id: int, q: Optional[str] = None):
    return {"item_id": item_id, "q": q}
```

**Nota**:

e vuoi approfondire, consulta la sezione  _"In a hurry?"_ su <a href="https://fastapi.tiangolo.com/async/#in-a-hurry" target="_blank">`async` e `await` nella documentazione</a>.

</details>

### Esegui il server

Puoi far partire il server così:

<div class="termy">

```console

@app.get("/items/{item_id}")
async def read_item(item_id: int, q: Union[str, None] = None):
    return {"item_id": item_id, "q": q}
```

**Note**:

如果你不知道是否会用到，可以查看文档的 _"In a hurry?"_ 章节中 <a href="https://fastapi.tiangolo.com/zh/async/#in-a-hurry" target="_blank">关于 `async` 和 `await` 的部分</a>。

</details>

### 运行

通过以下命令运行服务器：

<div class="termy">

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

    return {"item_id": item_id, "q": q}
```

**Примечание**:

Если вы не знаете, проверьте раздел _"Торопитесь?"_ <a href="https://fastapi.tiangolo.com/async/#in-a-hurry" target="_blank">в документации об `async` и `await`</a>.

</details>

### Запуск

Запустите сервер с помощью:

<div class="termy">

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

# About HTTPS

It is easy to assume that HTTPS is something that is just "enabled" or not.

But it is way more complex than that.

!!! tip
    If you are in a hurry or don't care, continue with the next sections for step by step instructions to set everything up with different techniques.

To **learn the basics of HTTPS**, from a consumer perspective, check <a href="https://howhttps.works/" class="external-link" target="_blank">https://howhttps.works/</a>.

Это всё не важно. **FastAPI** знает, что нужно сделать. 😎

!!! note "Информация"
    Если вам эта тема не знакома, прочтите [Async: *"In a hurry?"*](../../async.md){.internal-link target=_blank} раздел о `async` и `await` в документации.

## Интеграция с OpenAPI

また、通常の`def`*path operation関数*の中に`async def`を入れて依存関係を宣言したり、`async def`*path operation関数*の中に`def`を入れて依存関係を宣言したりすることなどができます。

それは重要ではありません。**FastAPI** は何をすべきかを知っています。

!!! note "備考"
    わからない場合は、ドキュメントの[Async: *"In a hurry?"*](../../async.md){.internal-link target=_blank}の中の`async`と`await`についてのセクションを確認してください。

## OpenAPIとの統合

依存関係（およびサブ依存関係）のすべてのリクエスト宣言、検証、および要件は、同じOpenAPIスキーマに統合されます。

つまり、対話型ドキュメントにはこれらの依存関係から得られる全ての情報も含まれているということです:
