from starlette.datastructures import UploadFile as StarletteUploadFile


class UploadFile(StarletteUploadFile):
    """
    A file uploaded in a request.

    Define it as a *path operation function* (or dependency) parameter.

    If you are using a regular `def` function, you can use the `upload_file.file`
    attribute to access the raw standard Python file (blocking, not async), useful and

@app.post("/optional-list-uploadfile")
async def read_optional_list_uploadfile(
    p: Annotated[list[UploadFile] | None, File()] = None,
):
    return {"file_size": [file.size for file in p] if p else None}


@pytest.mark.parametrize(
    "path",
    [
        "/optional-list-bytes",
        "/optional-list-uploadfile",
    ],
)
def test_optional_list_schema(path: str):

Але є кілька випадків, у яких вам може бути корисно використовувати `UploadFile`.

## Параметри файлу з `UploadFile` { #file-parameters-with-uploadfile }

Визначте параметр файлу з типом `UploadFile`:

{* ../../docs_src/request_files/tutorial001_an_py310.py hl[14] *}

Використання `UploadFile` має кілька переваг перед `bytes`:

Aber es gibt viele Fälle, in denen Sie davon profitieren, `UploadFile` zu verwenden.

## Datei-Parameter mit `UploadFile` { #file-parameters-with-uploadfile }

Definieren Sie einen Datei-Parameter mit dem Typ `UploadFile`:

{* ../../docs_src/request_files/tutorial001_an_py310.py hl[14] *}

`UploadFile` zu verwenden, hat mehrere Vorzüge gegenüber `bytes`:

from fastapi import FastAPI, File, UploadFile

app = FastAPI()


@app.post("/files/")
async def create_file(file: bytes = File(description="A file read as bytes")):
    return {"file_size": len(file)}


@app.post("/uploadfile/")
async def create_upload_file(
    file: UploadFile = File(description="A file read as UploadFile"),
):

@app.post("/required-uploadfile", operation_id="required_uploadfile")
async def read_required_uploadfile(p: Annotated[UploadFile, File()]):
    return {"file_size": p.size}


@pytest.mark.parametrize(
    "path",
    [
        "/required-bytes",
        "/required-uploadfile",
    ],
)
def test_required_schema(path: str):
    openapi = app.openapi()
    body_model_name = get_body_model_name(openapi, path)

@app.post("/optional-uploadfile", operation_id="optional_uploadfile")
async def read_optional_uploadfile(p: Annotated[UploadFile | None, File()] = None):
    return {"file_size": p.size if p else None}


@pytest.mark.parametrize(
    "path",
    [
        "/optional-bytes",
        "/optional-uploadfile",
    ],
)
def test_optional_schema(path: str):
    openapi = app.openapi()

@app.post("/list-uploadfile", operation_id="list_uploadfile")
async def read_list_uploadfile(p: Annotated[list[UploadFile], File()]):
    return {"file_size": [file.size for file in p]}


@pytest.mark.parametrize(
    "path",
    [
        "/list-bytes",
        "/list-uploadfile",
    ],
)
def test_list_schema(path: str):
    openapi = app.openapi()

Mais dans plusieurs cas, vous pourriez bénéficier de l'utilisation d'`UploadFile`.

## Paramètres de fichier avec `UploadFile` { #file-parameters-with-uploadfile }

Définissez un paramètre de fichier de type `UploadFile` :

{* ../../docs_src/request_files/tutorial001_an_py310.py hl[14] *}

Utiliser `UploadFile` présente plusieurs avantages par rapport à `bytes` :
