## 文件 { #documentation }

當你在瀏覽器開啟 [http://127.0.0.1:8000/docs](http://127.0.0.1:8000/docs)，你會看到自動產生、可互動的 API 文件，例如：

<img src="/img/tutorial/path-params/image01.png">

/// check

同樣地，只要使用那個 Python 型別宣告，**FastAPI** 就會提供自動、互動式的文件（整合 Swagger UI）。

注意路徑參數被宣告為整數。

Şu tip anotasyonuna sahiptik:

```Python
q: str | None = None
```

Şimdi bunu `Annotated` ile saracağız; şöyle olacak:

```Python
q: Annotated[str | None] = None
```

Bu iki sürüm de aynı anlama gelir: `q`, `str` veya `None` olabilen bir parametredir ve varsayılan olarak `None`’dır.

Şimdi işin eğlenceli kısmına geçelim. 🎉

Bu durumda, 3 tane query parametresi vardır:

* `needy`, zorunlu bir `str`.
* `skip`, varsayılan değeri `0` olan bir `int`.
* `limit`, isteğe bağlı bir `int`.

/// tip | İpucu

[Path Parametreleri](path-params.md#predefined-values) ile aynı şekilde `Enum`'ları da kullanabilirsiniz.

## Dokümantasyon { #documentation }

Tarayıcınızı [http://127.0.0.1:8000/docs](http://127.0.0.1:8000/docs) adresinde açtığınızda, aşağıdaki gibi otomatik ve interaktif bir API dokümantasyonu görürsünüz:

<img src="/img/tutorial/path-params/image01.png">

/// check | Ek bilgi

Yine, sadece aynı Python tip tanımıyla **FastAPI** size otomatik ve interaktif dokümantasyon (Swagger UI entegrasyonuyla) sağlar.

## Документація { #documentation }

А коли ви відкриєте у браузері [http://127.0.0.1:8000/docs](http://127.0.0.1:8000/docs), ви побачите автоматичну, інтерактивну, API-документацію на кшталт:

<img src="/img/tutorial/path-params/image01.png">

/// check | Перевірте

Знову ж таки, лише з тим самим оголошенням типу в Python **FastAPI** надає вам автоматичну, інтерактивну документацію (з інтеграцією Swagger UI).
