Les jetons Web JSON sont une norme couramment utilisée dans l'industrie pour transférer de manière sécurisée des informations en tant qu'objet JSON. Lorsque vous utilisez l'API Google Wallet, vous encodez les détails de l'objet Cartes que vous voulez utiliser pour créer une instance de carte au format JWT (prononcé "jot"), puis vous envoyez ce JWT dans une requête à l'API Google Wallet.
Les jetons JWT sont sécurisés en les signant avec un secret partagé avant d'être envoyés à l'API Google Wallet. Si vous utilisez l'API REST Google Wallet, la signature secrète est votre clé de compte de service Google Cloud. Si vous utilisez le SDK Google Wallet pour Android, la signature secrète est l'empreinte SHA-1 de votre application Android.
Encoder une carte dans un jeton JWT
Une fois le EventObject
créé, encapsulez-le avec un jeton JWT non signé doté de l'attribut payload.EventObjects
, comme indiqué dans l'extrait de code suivant:
JSON
{
"iss": "OWNER_EMAIL_ADDRESS",
"aud": "google",
"typ": "savetowallet",
"iat": "UNIX_TIME",
"origins": [],
"payload": {
"eventticketObjects": [ NEW_OBJECT ]
}
}
Pour en savoir plus sur le format attendu des jetons JWT, consultez la documentation de référence sur les jetons JWT.
Signer un jeton JWT
Les jetons JWT sont sécurisés en les signant avec un secret partagé avant d'être envoyés à l'API Google Wallet. Si vous utilisez l'API REST Google Wallet, la signature secrète est votre clé de compte de service Google Cloud. Si vous utilisez le SDK Google Wallet pour Android, la signature secrète est l'empreinte SHA-1 de votre application Android.
Web, e-mail et SMS
Le jeton JWT doit être signé à l'aide de la clé de compte de service associée au compte de service Google Cloud que vous avez autorisé dans la Business Console de Google Wallet. L'API Google Wallet valide ces revendications en vérifiant la signature du jeton JWT.
En signant le jeton JWT, vous obtenez un jeton qui peut ensuite être utilisé pour créer un lien "Ajouter à Google Wallet" permettant de fournir la carte à un utilisateur:

Applications Android
Lorsque la méthode savePasses
est appelée pour émettre une carte à un utilisateur, le SDK Android de Google Wallet signe automatiquement votre JWT avec l'empreinte SHA-1 de la clé de signature d'application que vous avez fournie dans la Business Console de Google Wallet. Vous pouvez également émettre la carte à l'aide d'un jeton JWT précédemment signé à l'aide de la méthode savePassesJwt
du SDK Android.
Pour en savoir plus, consultez Émettre des cartes avec le SDK Android.
