## Token JWT con scopes { #jwt-token-with-scopes }

Ahora, modifica la *path operation* del token para devolver los scopes solicitados.

Todavía estamos usando el mismo `OAuth2PasswordRequestForm`. Incluye una propiedad `scopes` con una `list` de `str`, con cada scope que recibió en el request.

Y devolvemos los scopes como parte del token JWT.

/// danger | Peligro

## Retorne o token { #return-the-token }

A resposta do endpoint `token` deve ser um objeto JSON.

Deve ter um `token_type`. No nosso caso, como estamos usando tokens "Bearer", o tipo de token deve ser "`bearer`".

E deve ter um `access_token`, com uma string contendo nosso token de acesso.
