Wenn Sie jedoch eine benutzerdefinierte Response-Klasse mit `None` als Medientyp angegeben haben, verwendet FastAPI `application/json` für jede zusätzliche Response, die über ein zugehöriges Modell verfügt.

///

## Informationen kombinieren

But if you have specified a custom response class with `None` as its media type, FastAPI will use `application/json` for any additional response that has an associated model.

///

## Combining information

set FILE_ARG=
:arg_loop
if "%~1" == "-f" (
  set "FILE_ARG=%~2"
  shift
  goto process_file_arg
)
if "%~1" == "--file" (
  set "FILE_ARG=%~2"
  shift
  goto process_file_arg
)
@REM If none of the above, skip the argument
shift
if not "%~1" == "" (
  goto arg_loop
) else (
  goto findBaseDir
)

:process_file_arg
if "%FILE_ARG%" == "" (
  goto findBaseDir
)

Mais si vous avez spécifié une classe de réponse personnalisée avec `None` comme type de média, FastAPI utilisera `application/json` pour toute réponse supplémentaire associée à un modèle.

from fastapi import FastAPI

app = FastAPI()


@app.get("/")
def read_root():
    return {"Hello": "World"}


@app.get("/items/{item_id}")

```

### Dockerfile

Now in the same project directory create a file `Dockerfile` with:

```{ .dockerfile .annotate }
# (1)!
FROM python:3.9

    assertTrue(copy instanceof ImmutableEnumSet);
  }

  public void testImmutableEnumSet_fromIterable() {
    ImmutableSet<SomeEnum> none = Sets.immutableEnumSet(MinimalIterable.<SomeEnum>of());
    assertThat(none).isEmpty();

    ImmutableSet<SomeEnum> one = Sets.immutableEnumSet(MinimalIterable.of(SomeEnum.B));
    assertThat(one).contains(SomeEnum.B);

from fastapi import FastAPI

app = FastAPI()


@app.get("/")
def read_root():
    return {"Hello": "World"}


@app.get("/items/{item_id}")
def read_item(item_id: int, q: Union[str, None] = None):
    return {"item_id": item_id, "q": q}
```
