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.

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

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

## Aceleniz mi var?

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

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

# Configuración Avanzada de Path Operation { #path-operation-advanced-configuration }

## operationId de OpenAPI { #openapi-operationid }

/// warning | Advertencia

Si no eres un "experto" en OpenAPI, probablemente no necesites esto.

///

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

Tienes que asegurarte de que sea único para cada operación.

# Configuración de Path Operation { #path-operation-configuration }

Hay varios parámetros que puedes pasar a tu *path operation decorator* para configurarlo.

/// warning | Advertencia

Ten en cuenta que estos parámetros se pasan directamente al *path operation decorator*, no a tu *path operation function*.

///

## Código de Estado del Response { #response-status-code }

Então, se você não fornecer uma, o **FastAPI** irá gerar automaticamente uma de "Resposta bem-sucedida".

## Descontinuar uma *operação de rota* { #deprecate-a-path-operation }

Se você precisar marcar uma *operação de rota* como <abbr title="obsoleta, recomendada não usá-la">descontinuada</abbr>, mas sem removê-la, passe o parâmetro `deprecated`:

# Path Operation Configuration { #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 { #response-status-code }

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

Daher, wenn Sie keine vergeben, wird **FastAPI** automatisch eine für „Erfolgreiche Response“ erstellen.

## Eine *Pfadoperation* deprecaten { #deprecate-a-path-operation }

Если вдруг вы не укажете его, то **FastAPI** автоматически сгенерирует это описание с текстом "Successful response".

## Обозначение *операции пути* как устаревшей { #deprecate-a-path-operation }

# Path Operation Advanced Configuration { #path-operation-advanced-configuration }

## OpenAPI operationId { #openapi-operationid }

/// warning

If you are not an "expert" in OpenAPI, you probably don't need this.

///

You can set the OpenAPI `operationId` to be used in your *path operation* with the parameter `operation_id`.

You would have to make sure that it is unique for each operation.

## OpenAPI operationId { #openapi-operationid }

/// warning | Achtung

Wenn Sie kein „Experte“ für OpenAPI sind, brauchen Sie dies wahrscheinlich nicht.

///

Mit dem Parameter `operation_id` können Sie die OpenAPI `operationId` festlegen, die in Ihrer *Pfadoperation* verwendet werden soll.

Sie müssten sicherstellen, dass sie für jede Operation eindeutig ist.
