Spesifikasyon ayrıca `username` ve `password`’ün form verisi olarak gönderilmesi gerektiğini de söyler (yani burada JSON yok).

### `scope` { #scope }

Spesifikasyon, client’ın "`scope`" adlı başka bir form alanı da gönderebileceğini söyler.

Form alanının adı `scope`’tur (tekil), ama aslında boşluklarla ayrılmış "scope"’lardan oluşan uzun bir string’dir.

**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.

                            <div class="row">
                                <div class="col-sm-12">
                                    <la:form styleClass="form-inline"
                                             action="/admin/crawlinginfo/">
                                        <div class="form-group">
