# Module `auth`
Ce module permet de récupérer des informations concernant l'utilisateur connecté et ses attributs.
## Méthodes
### `auth.getClaim(ctx: Context, name: string): string`
Récupère un attribut associé à l'utilisateur.
#### Arguments
- `ctx` **Context** Le contexte d'exécution. Voir la documentation du module [`context`](./context.md)
- `name` **string** Nom de l'attribut à retrouver
#### Valeur de retour
Valeur de l'attribut associé ou vide si la requête est non authentifiée ou que l'attribut n'a pas été trouvé.
#### Usage
```js
function onClientMessage(ctx, message) {
var subject = auth.getClaim(ctx, auth.CLAIM_SUBJECT);
console.log("Connected user is", subject);
}
```
## Propriétés
### `auth.CLAIM_SUBJECT`
Cette propriété identifie l'utilisateur connecté. Si la valeur retournée par la méthode `getClaim()` est vide, alors l'utilisateur n'est pas connecté.
### `auth.CLAIM_ROLE`
Cette propriété retourne le rôle de l'utilisateur connecté au sein du "tenant" courant. Si la valeur retournée par la méthode `getClaim()` est vide, alors l'utilisateur n'est pas connecté.
### `auth.PREFERRED_USERNAME`
Cette propriété retourne le nom "préféré pour l'affichage" de l'utilisateur connecté. Si la valeur retournée par la méthode `getClaim()` est vide, alors l'utilisateur n'est pas connecté ou l'utilisateur n'a pas défini de nom d'utilisateur particulier.
