Mesela GraphQL kullanırkan genelde tüm işlemleri yalnızca `POST` operasyonunu kullanarak gerçekleştirirsiniz.

### Adım 4: **Yol Operasyonu Fonksiyonunu** Tanımlayın

Aşağıdaki, bizim **yol operasyonu fonksiyonumuzdur**:

* **yol**: `/`
* **operasyon**: `get`
* **fonksiyon**: "dekoratör"ün (`@app.get("/")`'in) altındaki fonksiyondur.

```Python hl_lines="7"
{!../../docs_src/first_steps/tutorial001.py!}

*path operasyon fonksiyonu* için `async def `sözdizimi,  asenkron kod, eşzamanlılık ve paralellik hakkında bazı ayrıntılar.

## Aceleniz mi var?

<abbr title="too long; didn't read"><strong>TL;DR:</strong></abbr>

Eğer `await` ile çağrılması gerektiğini belirten üçüncü taraf kütüphaneleri kullanıyorsanız, örneğin:

```Python
results = await some_library()
```

# Path Operationの設定

*path operationデコレータ*を設定するためのパラメータがいくつかあります。

/// warning | "注意"

これらのパラメータは*path operation関数*ではなく、*path operationデコレータ*に直接渡されることに注意してください。

///

## レスポンスステータスコード

*path operation*のレスポンスで使用する（HTTP）`status_code`を定義することができます。

`404`のように`int`のコードを直接渡すことができます。

しかし、それぞれの番号コードが何のためのものか覚えていない場合は、`status`のショートカット定数を使用することができます:

```Python hl_lines="3  17"

# Path Operation Configuration

There are several parameters that you can pass to your *path operation decorator* to configure it.

/// warning

Notice that these parameters are passed directly to the *path operation decorator*, not to your *path operation function*.

///

## Response Status Code

You can define the (HTTP) `status_code` to be used in the response of your *path operation*.

You can pass directly the `int` code, like `404`.

## 弃用*路径操作*

`deprecated` 参数可以把*路径操作*标记为<abbr title="过时，建议不要使用">弃用</abbr>，无需直接删除：

```Python hl_lines="16"
{!../../docs_src/path_operation_configuration/tutorial006.py!}
```

API 文档会把该路径操作标记为弃用：

단일 *경로 작동*을 없애지 않고 <abbr title="구식, 사용하지 않는것이 권장됨">지원중단</abbr>을 해야한다면, `deprecated` 매개변수를 전달하면 됩니다.

```Python hl_lines="16"

Puedes asignar el `operationId` de OpenAPI para ser usado en tu *operación de path* con el parámetro `operation_id`.

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