    Note como `Offer` tem uma lista de `Item`s, que por sua vez possui opcionalmente uma lista `Image`s

## Corpos de listas puras

Se o valor de primeiro nível do corpo JSON que você espera for um `array` do JSON (uma` lista` do Python), você pode declarar o tipo no parâmetro da função, da mesma forma que nos modelos do Pydantic:


```Python
images: List[Image]
```

como em:

```Python hl_lines="15"

                ],
                "type": "object",
                "properties": {
                    "loc": {
                        "title": "Location",
                        "type": "array",
                        "items": {
                            "type": "string"
                        }
                    },
                    "msg": {
                        "title": "Message",

        get() {
            val sourcePsi = when {
                // array type for vararg parameters is not present in the code, so no need to handle it
                delegatedTypeRef?.source?.kind == KtFakeSourceElementKind.ArrayTypeFromVarargParameter -> null

                // but the array's underlying type is present with a fake source, and needs to be handled

Это всё не важно. **FastAPI** знает, что нужно сделать. 😎

    Если вам эта тема не знакома, прочтите [Async: *"In a hurry?"*](../../async.md){.internal-link target=_blank} раздел о `async` и `await` в документации.

## Интеграция с OpenAPI

## Тела с чистыми списками элементов

Если верхний уровень значения тела JSON-объекта представляет собой JSON `array` (в Python - `list`), вы можете объявить тип в параметре функции, так же, как в моделях Pydantic:

```Python
images: List[Image]
```

в Python 3.9 и выше:

```Python
images: list[Image]
```

  optional int32 endPort = 3;
}

// NetworkPolicySpec provides the specification of a NetworkPolicy
message NetworkPolicySpec {
  // podSelector selects the pods to which this NetworkPolicy object applies.
  // The array of ingress rules is applied to any pods selected by this field.
  // Multiple network policies can select the same set of pods. In this case,
  // the ingress rules for each are combined additively.

@app.get("/items/{item_id}")
async def read_item(item_id: int, q: Union[str, None] = None):
    return {"item_id": item_id, "q": q}
```

### 運行

使用以下指令運行伺服器：

<div class="termy">

```console
$ uvicorn main:app --reload

---

Novamente, esses são detalhes muito técnicos que provavelmente possam ser úteis caso você esteja procurando por eles.

```Python hl_lines="7"
{!../../../docs_src/first_steps/tutorial003.py!}
```

!!! note
    If you don't know the difference, check the [Async: *"In a hurry?"*](../async.md#in-a-hurry){.internal-link target=_blank}.

### Step 5: return the content

```Python hl_lines="8"
{!../../../docs_src/first_steps/tutorial001.py!}
```

    return {"item_id": item_id, "q": q}
```
