Tokeny internetowe JSON to powszechnie stosowany standard branżowy do bezpiecznego przesyłania informacji jako obiekt JSON. Korzystając z interfejsu Google Wallet API, zakodujesz szczegóły obiektu Karty, którego chcesz użyć do utworzenia instancji karty w formacie JWT (wyraz „jot”), a następnie wysyłasz ten token JWT w żądaniu do interfejsu Google Wallet API.
Tokeny JWT są bezpieczne, podpisując je udostępnionym tajnym kluczem, zanim zostaną przesłane do interfejsu Google Wallet API. Jeśli używasz interfejsu API typu REST Portfela Google, tajnym kluczem podpisywania jest klucz konta usługi Google Cloud. Jeśli używasz pakietu SDK Portfela Google na Androida, tajnym kluczem podpisywania jest odcisk cyfrowy SHA-1 aplikacji na Androida.
Kodowanie karty w tokenie JWT
Po utworzeniu obiektu EventObject opakuj go niepodpisanym tokenem JWT z atrybutem payload.EventObjects, jak w tym fragmencie:
JSON
{
"iss": "OWNER_EMAIL_ADDRESS",
"aud": "google",
"typ": "savetowallet",
"iat": "UNIX_TIME",
"origins": [],
"payload": {
"eventticketObjects": [ NEW_OBJECT ]
}
}Więcej informacji o oczekiwanym formacie tokenów JWT znajdziesz w dokumentacji JWT.
Podpisywanie JWT
Tokeny JWT są bezpieczne, podpisując je udostępnionym tajnym kluczem, zanim zostaną przesłane do interfejsu Google Wallet API. Jeśli używasz interfejsu API typu REST Portfela Google, tajnym kluczem podpisywania jest klucz konta usługi Google Cloud. Jeśli używasz pakietu SDK Portfela Google na Androida, tajnym kluczem podpisywania jest odcisk cyfrowy SHA-1 aplikacji na Androida.
Internet, e-maile i SMS-y
Token JWT musi być podpisany za pomocą klucza konta usługi powiązanego z kontem usługi Google Cloud autoryzowanym w konsoli biznesowej Portfela Google. Interfejs Google Wallet API zweryfikuje te deklaracje, weryfikując podpis JWT.
Zapisanie tokena JWT spowoduje utworzenie tokena, którego można użyć do utworzenia opcji „Dodaj do Portfela Google” który może być użyty do wydania karty użytkownikowi:

Aplikacje na Androida
Gdy metoda savePasses jest wywoływana w celu wydania karty użytkownikowi, pakiet SDK Portfela Google na Androida automatycznie podpisuje JWT za pomocą odcisku cyfrowego SHA-1 klucza podpisywania aplikacji podanego w Google Wallet Business Console. Możesz też opublikować kartę, korzystając z wcześniej podpisanego tokena JWT, używając metody savePassesJwt z pakietu SDK Androida.
