Crea parámetros de archivo y formulario de la misma manera que lo harías para `Body` o `Query`:

{* ../../docs_src/request_forms_and_files/tutorial001_an_py39.py hl[10:12] *}

Los archivos y campos de formulario se subirán como form data y recibirás los archivos y campos de formulario.

Y puedes declarar algunos de los archivos como `bytes` y algunos como `UploadFile`.

Crie parâmetros de arquivo e formulário da mesma forma que você faria para `Body` ou `Query`:

{* ../../docs_src/request_forms_and_files/tutorial001_an_py39.py hl[10:12] *}

Os arquivos e campos de formulário serão carregados como dados de formulário e você receberá os arquivos e campos de formulário.

E você pode declarar alguns dos arquivos como `bytes` e alguns como `UploadFile`.

Создайте ответ, как описано в [Вернуть Response напрямую](response-directly.md){.internal-link target=_blank}, и передайте заголовки как дополнительный параметр:

{* ../../docs_src/response_headers/tutorial001_py39.py hl[10:12] *}

/// note | Технические детали

Вы также можете использовать `from starlette.responses import Response` или `from starlette.responses import JSONResponse`.

		if _, err := parseCopyPartRangeSpec(rangeString); err == nil {
			t.Fatalf("expected: an error, got: <nil> for range %s", rangeString)
		}
	}

	// Test error range strings.
	errorRangeString := []string{
		"bytes=10-10",
		"bytes=20-30",
	}
	for _, rangeString := range errorRangeString {
		rs, err := parseCopyPartRangeSpec(rangeString)
		if err == nil {
			err1 := checkCopyPartRangeWithSize(rs, objectSize)

Luego establece Cookies en ella, y luego devuélvela:

{* ../../docs_src/response_cookies/tutorial001_py39.py hl[10:12] *}

/// tip | Consejo

Ten en cuenta que si devuelves un response directamente en lugar de usar el parámetro `Response`, FastAPI lo devolverá directamente.

## Define `File` and `Form` parameters { #define-file-and-form-parameters }

Create file and form parameters the same way you would for `Body` or `Query`:

{* ../../docs_src/request_forms_and_files/tutorial001_an_py39.py hl[10:12] *}

The files and form fields will be uploaded as form data and you will receive the files and form fields.

And you can declare some of the files as `bytes` and some as `UploadFile`.
