The instance of the dependency class `OAuth2PasswordRequestForm` won't have an attribute `scope` with the long string separated by spaces, instead, it will have a `scopes` attribute with the actual list of strings for each scope sent.

We are not using `scopes` in this example, but the functionality is there if you need it.

Now, get the user data from the (fake) database, using the `username` from the form field.

  is a map of domain to list of nameservers for the domain. This is used
  to inject private DNS domains into the kube-dns namespace. In the above
  example, any DNS requests for *.acme.local will be served by the
  nameserver 1.2.3.4.

  "upstreamNameservers": ["8.8.8.8", "8.8.4.4"]

  is a list of upstreamNameservers to use, overriding the configuration

### Étape 5 : retourner le contenu

{* ../../docs_src/first_steps/tutorial001.py hl[8] *}

Vous pouvez retourner un dictionnaire (`dict`), une liste (`list`), des valeurs seules comme des chaines de caractères (`str`) et des entiers (`int`), etc.

Vous pouvez aussi retourner des models **Pydantic** (qui seront détaillés plus tard).

/// tip | Dica

Quando você lançar um `HTTPException`, você pode passar qualquer valor convertível em JSON como parâmetro de `detail`, e não apenas `str`.

Você pode passar um `dict` ou um `list`, etc.
Esses tipos de dados são manipulados automaticamente pelo **FastAPI** e convertidos em JSON.
