`dependências`

Da mesma forma que você pode definir uma `list` de `Depends` no parâmetro de `dependencias` do decorador (como explicado em [Dependências em decoradores de operações de rota](../../tutorial/dependencies/dependencies-in-path-operation-decorators.md){.internal-link target=_blank}), você também pode utilizar `Security` com escopos lá....

```JSON
{"item_id": 5, "q": "somequery"}
```

Damit haben Sie bereits eine API erstellt, welche:

* HTTP-Anfragen auf den _Pfaden_ `/` und `/items/{item_id}` entgegennimmt.
* Beide _Pfade_ erhalten `GET` Operationen (auch bekannt als HTTP _Methoden_).
* Der _Pfad_ `/items/{item_id}` hat einen _Pfadparameter_ `item_id`, der ein `int` sein sollte.
* Der _Pfad_ `/items/{item_id}` hat einen optionalen `str` _Query Parameter_ `q`.

def get_body_field(
    *, flat_dependant: Dependant, name: str, embed_body_fields: bool
) -> Optional[ModelField]:
    """
    Get a ModelField representing the request body for a path operation, combining
    all body parameters into a single field if necessary.

    Used to check if it's form data (with `isinstance(body_field, params.Form)`)
    or JSON and to generate the JSON Schema for a request body.

   * exhausted: its {@code hasNext()} method will return {@code false}.
   *
   * @return {@code true} if {@code collection} was modified as a result of this operation

      Collection<T> addTo, Iterator<? extends T> iterator) {

Verás la respuesta de JSON cómo:

```JSON
{"item_id": 5, "q": "somequery"}
```

Ya creaste una API que:

* Recibe HTTP requests en los _paths_ `/` y `/items/{item_id}`.
* Ambos _paths_ toman operaciones `GET` (también conocido como HTTP _methods_).
* El _path_ `/items/{item_id}` tiene un _path parameter_ `item_id` que debería ser un `int`.
* El _path_ `/items/{item_id}` tiene un `str` _query parameter_ `q` opcional.

 * (note: even fixed-length splitters).
 *
 * <p>Splitter instances are thread-safe immutable, and are therefore safe to store as {@code static
 * final} constants.
 *
 * <p>The {@link Joiner} class provides the inverse operation to splitting, but note that a
 * round-trip between the two should be assumed to be lossy.
