Todo o processo que era aplicado para parâmetros de rota também é aplicado para parâmetros de consulta:

* Suporte do editor (obviamente)
* <dfn title="convertendo a string que vem de um request HTTP em dados Python">"análise"</dfn> de dados
* Validação de dados
* Documentação automática

## Valores padrão { #defaults }

Once the response has been received, the connection will be returned to the pool so it can be reused for a future request. Connections are evicted from the pool after a period of inactivity.

  @Override
  public double doubleValue() {
    return get();
  }

  /**
   * Saves the state to a stream (that is, serializes it).
   *
   * @serialData The current value is emitted (a {@code double}).
   */
  private void writeObject(ObjectOutputStream s) throws IOException {
    s.defaultWriteObject();

    s.writeDouble(get());
  }

You don't really need to declare the return type annotation for streaming binary data.

As FastAPI will not try to convert the data to JSON with Pydantic or serialize it in any way, in this case, the type annotation is only for your editor and tools to use, it won't be used by FastAPI.

```Python

## Підтримка в редакторі всюди { #editor-support-everywhere }

Ви отримаєте підтримку в редакторі всюди.

Навіть для елементів у списках:

<img src="/img/tutorial/body-nested-models/image01.png">

```console
$ fastapi dev main.py
```

Aber Sie müssten sich merken, bei jedem Aufruf des `fastapi`-Befehls den korrekten Pfad zu übergeben.

Zusätzlich könnten andere Tools sie nicht finden, z. B. die [VS Code Extension](editor-support.md) oder [FastAPI Cloud](https://fastapicloud.com), daher wird empfohlen, den `entrypoint` in `pyproject.toml` zu verwenden.

## `fastapi dev` { #fastapi-dev }

$ fastapi dev main.py
```

But you would have to remember to pass the correct path every time you call the `fastapi` command.

Additionally, other tools might not be able to find it, for example the [VS Code Extension](editor-support.md) or [FastAPI Cloud](https://fastapicloud.com), so it is recommended to use the `entrypoint` in `pyproject.toml`.

## `fastapi dev` { #fastapi-dev }

Running `fastapi dev` initiates development mode.

```

Mas você teria que lembrar de passar o caminho correto toda vez que chamar o comando `fastapi`.

Além disso, outras ferramentas podem não conseguir encontrá-la, por exemplo a [Extensão do VS Code](editor-support.md) ou a [FastAPI Cloud](https://fastapicloud.com), então é recomendado usar o `entrypoint` em `pyproject.toml`.

## `fastapi dev` { #fastapi-dev }

Executar `fastapi dev` inicia o modo de desenvolvimento.

```Python
commons = Depends(CommonQueryParams)
```

... comme dans :

{* ../../docs_src/dependencies/tutorial003_an_py310.py hl[19] *}

Mais il est recommandé de déclarer le type ; ainsi, votre éditeur saura ce qui sera passé comme paramètre `commons`, et pourra vous aider avec l'autocomplétion, les vérifications de type, etc. :

## Raccourci { #shortcut }

Comme FastAPI n'essaiera pas de convertir les données en JSON avec Pydantic ni de les sérialiser, dans ce cas l'annotation de type ne sert qu'à votre éditeur et à vos outils ; elle ne sera pas utilisée par FastAPI.
