Esempio di attestazioni di protezione per un dispositivo edge
L'esempio riportato di seguito illustra in che modo è possibile aggiungere attestazioni di protezione a un dispositivo edge e inviarle a ThingWorx Platform.
Questo esempio esegue alcune operazioni, tra cui quelle riportate di seguito.
• Definisce l'istanza di ThingWorx Platform di destinazione a cui vengono inviate le attestazioni di protezione.
• Definisce un client API per il dispositivo edge, impostando le attestazioni di protezione e la piattaforma di destinazione.
• Illustra come vengono elaborate le attestazioni di protezione fornendo alcuni insiemi di attestazioni non valide e uno di attestazioni di protezione valide.
