By default, **FastAPI** will then expect its body directly.

But if you want it to expect a JSON with a key `item` and inside of it the model contents, as it does when you declare extra body parameters, you can use the special `Body` parameter `embed`:

```Python
item: Item = Body(embed=True)
```

## Restrinja Parâmetros de Consulta Extras { #forbid-extra-query-parameters }

Em alguns casos especiais (provavelmente não muito comuns), você queira **restringir** os parâmetros de consulta que deseja receber.

Você pode usar a configuração do modelo Pydantic para `forbid` qualquer campo `extra`:

// Regular object test type.
type objTestType func(obj ObjectLayer, instanceType string, t TestErrHandler)

// Special test type for test with directories
type objTestTypeWithDirs func(obj ObjectLayer, instanceType string, dirs []string, t TestErrHandler)

// Special object test type for disk not found situations.
type objTestDiskNotFoundType func(obj ObjectLayer, instanceType string, dirs []string, t *testing.T)

### Contenedores con Múltiples Procesos y Casos Especiales { #containers-with-multiple-processes-and-special-cases }

Por supuesto, hay **casos especiales** donde podrías querer tener **un contenedor** con varios **worker processes de Uvicorn** dentro.
