잠금 아이콘을 클릭하고 로그아웃한 다음 동일한 작업을 다시 시도하면 다음과 같은 HTTP 401 오류가 발생합니다.

```JSON
{
  "detail": "Not authenticated"
}
```

### 비활성된 유저

이제 비활성된 사용자로 시도하고, 인증해봅시다:

유저명: `alice`

패스워드: `secret2`

그리고 `/users/me` 경로와 함께 `GET` 작업을 사용해 봅시다.

다음과 같은 "Inactive user" 오류가 발생합니다:

```JSON
{
  "detail": "Inactive user"
}
```

Il y a un petit détail sur les noms à garder à l'esprit. 💡

If you open in your browser a URL like:

```
http://127.0.0.1:8000/items/foo-item
```

...without adding the required parameter `needy`, you will see an error like:

```JSON
{
  "detail": [
    {
      "type": "missing",
      "loc": [
        "query",
        "needy"
      ],
      "msg": "Field required",
      "input": null,
      "url": "https://errors.pydantic.dev/2.1/v/missing"

Para esos casos, puedes usar el `jsonable_encoder` para convertir tus datos antes de pasarlos a la respuesta:

```Python hl_lines="4 6 20 21"
{!../../docs_src/response_directly/tutorial001.py!}
```

/// note | Detalles Técnicos

También puedes usar `from starlette.responses import JSONResponse`.

import javax.annotation.CheckForNull;
import org.checkerframework.checker.nullness.qual.NonNull;

/// note | Detalles Técnicos

También podrías utilizar `from starlette.responses import Response` o `from starlette.responses import JSONResponse`.

Si vous ouvrez une URL comme :

```
http://127.0.0.1:8000/items/foo-item
```

...sans ajouter le paramètre requis `needy`, vous aurez une erreur :

```JSON
{
    "detail": [
        {
            "loc": [
                "query",
                "needy"
            ],
            "msg": "field required",
            "type": "value_error.missing"
        }
    ]
}
