Si un cliente intenta enviar datos extra, recibirá un response de **error**.

Por ejemplo, si el cliente intenta enviar los campos de formulario:

* `username`: `Rick`
* `password`: `Portal Gun`
* `extra`: `Mr. Poopybutthole`

Recibirá un response de error indicando que el campo `extra` no está permitido:

```json
{
    "detail": [
        {

```Python
q: Annotated[str, Query(default="rick")] = "morty"
```

... denn es ist nicht klar, ob der Defaultwert `"rick"` oder `"morty"` sein soll.

Sie würden also (bevorzugt) schreiben:

```Python
q: Annotated[str, Query()] = "rick"
```

... oder in älteren Codebasen finden Sie:

```Python
q: str = Query(default="rick")
```

```Python
q: Annotated[str, Query(default="rick")] = "morty"
```

...porque não está claro se o valor padrão deveria ser `"rick"` ou `"morty"`.

Então, você usaria (preferencialmente):

```Python
q: Annotated[str, Query()] = "rick"
```

...ou em bases de código mais antigas você encontrará:

```Python
q: str = Query(default="rick")
```

            "X-Token": "fake-super-secret-token",
            "X-Key": "fake-super-secret-key",
        },
    )
    assert response.status_code == 200, response.text
    assert response.json() == [{"username": "Rick"}, {"username": "Morty"}]


def test_openapi_schema(client: TestClient):
    response = client.get("/openapi.json")
    assert response.status_code == 200, response.text
    assert response.json() == {

Caso um cliente tente enviar informações adicionais, ele receberá um retorno de **erro**.

Por exemplo, se o cliente tentar enviar os campos de formulário:

* `username`: `Rick`
* `password`: `Portal Gun`
* `extra`: `Mr. Poopybutthole`

Ele receberá um retorno de erro informando-o que o campo `extra` não é permitido:

```json
{
    "detail": [
        {

If a client tries to send some extra data, they will receive an **error** response.

For example, if the client tries to send the form fields:

* `username`: `Rick`
* `password`: `Portal Gun`
* `extra`: `Mr. Poopybutthole`

They will receive an error response telling them that the field `extra` is not allowed:

```json
{
    "detail": [
        {

///

您可以使用 Pydantic 的模型配置来禁止（ `forbid` ）任何额外（ `extra` ）字段：

{* ../../docs_src/request_form_models/tutorial002_an_py39.py hl[12] *}

如果客户端尝试发送一些额外的数据，他们将收到**错误**响应。

例如，如果客户端尝试发送这样的表单字段：

* `username`: `Rick`
* `password`: `Portal Gun`
* `extra`: `Mr. Poopybutthole`

他们将收到一条错误响应，表明字段 `extra` 是不被允许的：

```json
{
    "detail": [
        {
            "type": "extra_forbidden",

    end
