Générer le jeton web JSON et le jeton d’accès generating-json-web-token-and-access-token
[AEM Forms 6.5]{class="badge informative"}
Cet article explique le code nécessaire à la génération du jeton web JSON (JWT) et du jeton d’accès requis pour effectuer des appels REST vers Adobe Campaign Standard.
Générer un jeton web JSON generate-json-web-token
La première étape de l’utilisation de l’API Adobe Campaign consiste à générer un JWT. Il existe de nombreux exemples de code sur la manière de générer un JWT pour ACS. Vous pouvez suivre cet exemple de code Java pour générer le JWT.
Pour utiliser l’API ACS avec AEM Forms, nous devons créer le JWT dans un lot OSGi. L’extrait de code suivant a été utilisé pour générer le JWT dans cet exemple de lot OSGI. Les détails de l’instance ACS sont récupérés à partir des propriétés de configuration OSGI définies comme illustré ci-dessus.
A. Les valeurs affichées ici sont factices.
Le code suivant récupère les détails sur le serveur Adobe Campaign à partir de la configuration OSGI. Nous créons une clé privée des lignes 80 à 104.
Une fois que nous avons la clé privée, nous créons le jeton web JSON.

Générer un jeton d’accès generate-access-token
Nous échangeons ensuite le JWT généré pour un jeton d’accès en effectuant un appel POST. Ce jeton d’accès est alors envoyé en tant que clé d’autorisation dans l’en-tête HTTP pour les appels REST suivants.
