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": [
        {

  /**
   * {@inheritDoc}
   *
   * <p>Implementations may or may not support removal when a call to {@link #peek()} has occurred
   * since the most recent call to {@link #next()}.
   *
   * @throws IllegalStateException if there has been a call to {@link #peek()} since the most recent
   *     call to {@link #next()} and this implementation does not support this sequence of calls
   *     (optional)
   */
  @Override
  void remove();

Um `Request` também tem um `request.receive`, que é uma função para "receber" o corpo da requisição.

Um `Request` também tem um `request.receive`, que é uma função para "receber" o corpo da requisição.

O dicionário `scope` e a função `receive` são ambos parte da especificação ASGI.

E essas duas coisas, `scope` e `receive`, são o que é necessário para criar uma nova instância de `Request`.

# Request Files

You can define files to be uploaded by the client using `File`.

/// info

To receive uploaded files, first install <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>.

Make sure you create a [virtual environment](../virtual-environments.md){.internal-link target=_blank}, activate it, and then install it, for example:

```console
$ pip install python-multipart
```

`PUT` is used to receive data that should replace the existing data.

### Warning about replacing

That means that if you want to update the item `bar` using `PUT` with a body containing:

```Python
{
    "name": "Barz",

For example, it doesn't receive `datetime` objects, as those are not compatible with JSON.

So, a `datetime` object would have to be converted to a `str` containing the data in <a href="https://en.wikipedia.org/wiki/ISO_8601" class="external-link" target="_blank">ISO format</a>.

The same way, this database wouldn't receive a Pydantic model (an object with attributes), only a `dict`.

Ein `Request` hat auch ein `request.receive`, welches eine Funktion ist, die den Hauptteil des Requests empfängt.

Das `scope`-`dict` und die `receive`-Funktion sind beide Teil der ASGI-Spezifikation.

Und diese beiden Dinge, `scope` und `receive`, werden benötigt, um eine neue `Request`-Instanz zu erstellen.
