Aber erinnern Sie sich, dass, wenn Sie `Query`, `Path`,  `Header` und andere von `fastapi` importieren, diese tatsächlich Funktionen sind, welche spezielle Klassen zurückgeben.

!!! info
    Um Header zu deklarieren, müssen Sie `Header` verwenden, da diese Parameter sonst als Query-Parameter interpretiert werden würden.

# `APIRouter`-Klasse

Hier sind die Referenzinformationen für die Klasse `APIRouter` mit all ihren Parametern, Attributen und Methoden.

Sie können die `APIRouter`-Klasse direkt von `fastapi` importieren:

```python
from fastapi import APIRouter
```

::: fastapi.APIRouter
    options:
        members:
            - websocket
            - include_router
            - get
            - put
            - post
            - delete

Refer to sizing guide for more understanding on default values chosen depending on your erasure stripe size [here](https://github.com/minio/minio/blob/master/docs/distributed/SIZING.md). Parity settings can be changed using [storage classes](https://github.com/minio/minio/tree/master/docs/erasure/storage-class).

### Criando uma classe `Enum`

Importe `Enum` e crie uma sub-classe que herde de `str` e de `Enum`.

Por herdar de `str` a documentação da API vai ser capaz de saber que os valores devem ser do tipo `string` e assim ser capaz de mostrar eles corretamente.

Assim, crie atributos de classe com valores fixos, que serão os valores válidos disponíveis.

  // One of Never, PreemptLowerPriority.
  // Defaults to PreemptLowerPriority if unset.
  // +optional
  optional string preemptionPolicy = 5;
}

// PriorityClassList is a collection of priority classes.
message PriorityClassList {
  // Standard list metadata
  // More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata
  // +optional

### Passo 1: importe `FastAPI`

```Python hl_lines="1"
{!../../../docs_src/first_steps/tutorial001.py!}
```

`FastAPI` é uma classe Python que fornece todas as funcionalidades para sua API.

!!! note "Detalhes técnicos"
    `FastAPI` é uma classe que herda diretamente de `Starlette`.
