I token web JSON sono uno standard di settore di uso comune per il trasferimento sicuro delle informazioni come oggetti JSON. Quando utilizzi l'API Google Wallet, codifichi i dettagli dell'oggetto tessere che vuoi utilizzare per creare un'istanza della tessera in formato JWT (pronunciato "jot"), quindi invii quel JWT in una richiesta all'API Google Wallet.
I JWT vengono protetti grazie alla firma con un segreto condiviso prima che vengano inviati all'API Google Wallet. Se utilizzi l'API REST Google Wallet, il secret di firma è la chiave dell'account di servizio Google Cloud. Se utilizzi l'SDK Google Wallet per Android, il segreto di firma è l'impronta SHA-1 per la tua app Android.
Codifica una tessera in un JWT
Quando viene creato TransitObject, aggregalo a un JWT non firmato con l'attributo payload.TransitObjects, come mostrato nello snippet seguente:
JSON
{
"iss": "OWNER_EMAIL_ADDRESS",
"aud": "google",
"typ": "savetowallet",
"iat": "UNIX_TIME",
"origins": [],
"payload": {
"transitObjects": [ NEW_OBJECT ]
}
}Per ulteriori informazioni sul formato previsto dei JWT, consulta la documentazione di riferimento JWT.
Firma un JWT
I JWT vengono protetti grazie alla firma con un segreto condiviso prima che vengano inviati all'API Google Wallet. Se utilizzi l'API REST Google Wallet, il secret di firma è la chiave dell'account di servizio Google Cloud. Se utilizzi l'SDK Google Wallet per Android, il segreto di firma è l'impronta SHA-1 per la tua app Android.
Web, email e SMS
Il JWT deve essere firmato utilizzando la chiave dell'account di servizio associata all'account di servizio Google Cloud che hai autorizzato nella Business Console di Google Wallet. L'API Google Wallet convaliderà queste rivendicazioni verificando la firma JWT.
Se firmi il JWT, verrà generato un token che potrai utilizzare per creare un pulsante "Aggiungi a Google Wallet" link che può essere utilizzato per emettere la tessera a un utente:

App Android
Quando il metodo savePasses viene chiamato per emettere una tessera a un utente, l'SDK Google Wallet per Android firma automaticamente il tuo JWT con l'impronta SHA-1 della chiave di firma dell'app che hai fornito nella Business Console di Google Wallet. In alternativa, puoi anche emettere la tessera utilizzando un JWT firmato in precedenza utilizzando il metodo savePassesJwt dell'SDK Android.
Per maggiori informazioni, consulta la sezione Emissione di tessere con l'SDK per Android.
