## Qu'est-ce que les « données de formulaire » { #what-is-form-data }

La façon dont les formulaires HTML (`<form></form>`) envoient les données au serveur utilise normalement un encodage « spécial » pour ces données, différent de JSON.

**FastAPI** s'assure de lire ces données au bon endroit plutôt que depuis JSON.

                                                    <div class="form-group row">
                                                        <label for="name" class="col-sm-3 text-sm-right col-form-label"><la:message
                                                                key="labels.storage_folder_name"/></label>
                                                        <div class="form-inline col-sm-9">

**FastAPI** наследует `UploadFile` непосредственно из **Starlette**, но добавляет некоторые детали для совместимости с **Pydantic** и другими частями FastAPI.

## Что такое «данные формы» { #what-is-form-data }

Способ, которым HTML-формы (`<form></form>`) отправляют данные на сервер, обычно использует "специальную" кодировку для этих данных, отличную от JSON.

**FastAPI** позаботится о том, чтобы считать эти данные из нужного места, а не из JSON.

The spec also states that the `username` and `password` must be sent as form data (so, no JSON here).

### `scope` { #scope }

The spec also says that the client can send another form field "`scope`".

The form field name is `scope` (in singular), but it is actually a long string with "scopes" separated by spaces.

Each "scope" is just a string (without spaces).
