Dados vindos de formulários geralmente tem a codificação com o "media type" `application/x-www-form-urlencoded` quando estes não incluem arquivos.

Daten aus Formularen werden, wenn es keine Dateien sind, normalerweise mit dem <abbr title='Media type – Medientyp, Typ des Mediums'>„media type“</abbr> `application/x-www-form-urlencoded` kodiert.

**FastAPI** se asegurará de leer esos datos del lugar correcto en lugar de JSON.

/// note | Detalles Técnicos

Los datos de los forms normalmente se codifican usando el "media type" `application/x-www-form-urlencoded` cuando no incluyen archivos.

Sie können mehrere `File`- und `Form`-Parameter in einer *Pfadoperation* deklarieren, aber Sie können nicht gleichzeitig auch `Body`-Felder deklarieren, welche Sie als JSON erwarten, da der Request den Body mittels `multipart/form-data` statt `application/json` kodiert.

Das ist keine Limitation von **FastAPI**, sondern Teil des HTTP-Protokolls.

## Zusammenfassung

Os conteúdos que você retorna em sua *função de operador de rota* serão colocados dentro dessa `Response`.

E se a `Response` tiver um media type JSON (`application/json`), como é o caso com `JSONResponse` e `UJSONResponse`, os dados que você retornar serão automaticamente convertidos (e filtrados) com qualquer `response_model` do Pydantic que for declarado em sua *função de operador de rota*.

const (
	// Means no response type.
	mimeNone mimeType = ""
	// Means response type is JSON.
	mimeJSON mimeType = "application/json"
	// Means response type is XML.
	mimeXML mimeType = "application/xml"
)

// writeSuccessResponseJSON writes success headers and response if any,
// with content-type set to `application/json`.
func writeSuccessResponseJSON(w http.ResponseWriter, response []byte) {
