### Otomatik dokümantasyon


OpenAPI standartlarına dayalı olan bir framework olarak, geliştiricilerin birden çok seçeneği var, varsayılan olarak gelen 2 farklı interaktif API dokümantasyonu ve web kullanıcı arayüzü var.

* Validación para tipos más exóticos, como:
    * URL.
    * Email.
    * UUID.
    * ...y otros.

Toda la validación es manejada por **Pydantic**, una herramienta bien establecida y robusta.

### Seguridad y autenticación { #security-and-authentication }

Seguridad y autenticación integradas. Sin ningún compromiso con bases de datos o modelos de datos.

///

**FastAPI** est basé entièrement sur **Pydantic**.

Vous verrez bien plus d'exemples de son utilisation dans [Tutoriel - Guide utilisateur](tutorial/index.md){.internal-link target=_blank}.

## Les annotations de type dans **FastAPI**

Try to avoid using bitter sarcasm or potentially passive-aggressive comments. If something is wrong, it's better to be direct (try to be gentle) than sarcastic.

Try to be as specific and objective as possible, avoid generalizations.

    // Serial form:
    // 1 signed byte for the strategy
    // 1 unsigned byte for the number of hash functions
    // 1 big endian int, the number of longs in our bitset
    // N big endian longs of our bitset
    DataOutputStream dout = new DataOutputStream(out);
    dout.writeByte(SignedBytes.checkedCast(strategy.ordinal()));

```

The TLS versions and cipher suites in each spec can change with each release. For example, in OkHttp 2.2 we dropped support for SSL 3.0 in response to the [POODLE](https://googleonlinesecurity.blogspot.ca/2014/10/this-poodle-bites-exploiting-ssl-30.html) attack. And in OkHttp 2.3 we dropped support for [RC4](https://en.wikipedia.org/wiki/RC4#Security). As with your desktop web browser, staying up-to-date with OkHttp is the best way to stay secure.

```

...ce qui fonctionnerait :

```JSON
{
    "item_id": "foo-item",
    "needy": "sooooneedy"
}
```

Et bien sur, vous pouvez définir certains paramètres comme requis, certains avec des valeurs par défaut et certains entièrement optionnels :

diese Weise würde die Session die Datenbankverbindung freigeben, sodass andere Requests sie verwenden könnten.
