Vamos utilizar essa aplicação como exemplo:

```Python hl_lines="9"
{!../../docs_src/query_params_str_validations/tutorial001.py!}
```

O parâmetro de consulta `q` é do tipo `Union[str, None]`, o que significa que é do tipo `str` mas que também pode ser `None`, e de fato, o valor padrão é `None`, então o FastAPI saberá que não é obrigatório.

# MinIO Logging Quickstart Guide [![Slack](https://slack.min.io/slack?type=svg)](https://slack.min.io)

This document explains how to configure MinIO server to log to different logging targets.

## Log Targets

MinIO supports currently two target types

- console
- http

### Logging Console Target

Console target is on always and cannot be disabled.

### Logging HTTP Target

```

Here the query parameter `needy` is a required query parameter of type `str`.

If you open in your browser a URL like:

```
http://127.0.0.1:8000/items/foo-item
```

...without adding the required parameter `needy`, you will see an error like:

```JSON
{
  "detail": [
    {
      "type": "missing",
      "loc": [
        "query",
        "needy"
      ],

  }
