> Quelle est l'histoire de ce projet ? Il semble être sorti de nulle part et est devenu génial en quelques semaines [...].

Voici un petit bout de cette histoire.

## Alternatives

Je crée des API avec des exigences complexes depuis plusieurs années (Machine Learning, systèmes distribués, jobs asynchrones, bases de données NoSQL, etc), en dirigeant plusieurs équipes de développeurs.

Você provavelmente não precisará utilizar esses headers diretamente no seu código.

Mas caso você precise, para um cenário mais complexo, você pode adicionar headers customizados:

```Python hl_lines="14"
{!../../docs_src/handling_errors/tutorial002.py!}
```

## Instalando manipuladores de exceções customizados

Eles tendem a exigir configurações mais complexas, um gerenciador de fila de mensagens/tarefas, como RabbitMQ ou Redis, mas permitem que você execute tarefas em segundo plano em vários processos e, especialmente, em vários servidores.

<font color="#4E9A06">INFO</font>:     Waiting for application startup.
<font color="#4E9A06">INFO</font>:     Application startup complete.

`fastapi`라고 불리는 명령어 프로그램은 **FastAPI CLI**입니다.

FastAPI CLI는 Python 프로그램의 경로(예: `main.py`)를 인수로 받아, `FastAPI` 인스턴스(일반적으로 `app`으로 명명)를 자동으로 감지하고 올바른 임포트 과정을 결정한 후 이를 실행합니다.

## HTTP Trace

HTTP tracing can be enabled by using [`mc admin trace`](https://github.com/minio/mc/blob/master/docs/minio-admin-complete-guide.md#command-trace---display-minio-server-http-trace) command.

Example:

```sh
minio server /data
```

Default trace is succinct only to indicate the API operations being called and the HTTP response status.

But here's the key point.

The security and dependency injection stuff is written once.

And you can make it as complex as you want. And still, have it written only once, in a single place. With all the flexibility.

But you can have thousands of endpoints (*path operations*) using the same security system.

You can use the same type declarations with `str`, `float`, `bool` and many other complex data types.

Several of these are explored in the next chapters of the tutorial.

## Order matters

When creating *path operations*, you can find situations where you have a fixed path.

* **Mniejsza ilość błędów**: Zmniejsza ilość ludzkich (dewelopera) błędy o około 40%. *
* **Intuicyjność**: Wspaniałe wsparcie dla edytorów kodu. Dostępne wszędzie <abbr title="znane jako auto-complete, autocompletion, IntelliSense">automatyczne uzupełnianie</abbr> kodu. Krótszy czas debugowania.
* **Łatwość**: Zaprojektowany by być prosty i łatwy do nauczenia. Mniej czasu spędzonego na czytanie dokumentacji.
