Веб-токены JSON — это широко используемый отраслевой стандарт для безопасной передачи информации в виде объекта JSON. При использовании API Google Кошелька вы кодируете данные объекта Passes, который хотите использовать для создания экземпляра пропуска, в формате JWT (произносится как «jot»), а затем отправляете этот JWT в запросе к API Google Кошелька.
JWT обеспечиваются в безопасности путем подписания их общим секретом перед отправкой в API Google Кошелька. Если вы используете REST API Google Кошелька, секретом подписи является ключ вашей учетной записи службы Google Cloud. Если вы используете Google Wallet Android SDK, секретом подписи является отпечаток SHA-1 вашего приложения Android.
Закодируйте проход в JWT
Когда GiftCardObject будет создан, оберните его беззнаковым JWT с атрибутом payload.GiftCardObjects , как показано в следующем фрагменте:
JSON
{
"iss": "OWNER_EMAIL_ADDRESS",
"aud": "google",
"typ": "savetowallet",
"iat": "UNIX_TIME",
"origins": [],
"payload": {
"giftcardObjects": [ NEW_OBJECT ]
}
}Дополнительные сведения об ожидаемом формате JWT см. в справочнике по JWT .
Подпишите JWT
JWT обеспечиваются в безопасности путем подписания их общим секретом перед отправкой в API Google Кошелька. Если вы используете REST API Google Кошелька, секретом подписи является ключ вашей учетной записи службы Google Cloud. Если вы используете Google Wallet Android SDK, секретом подписи является отпечаток SHA-1 вашего приложения Android.
Интернет, электронная почта и SMS
JWT необходимо подписать с помощью ключа учетной записи службы, связанного с учетной записью службы Google Cloud, которую вы авторизовали в бизнес-консоли Google Wallet . API Google Кошелька проверит эти утверждения, проверив подпись JWT.
Подписание JWT создаст токен, который затем можно будет использовать для создания ссылки «Добавить в Google Кошелек», которую можно использовать для выдачи пропуска пользователю:

Приложения для Android
Когда для выдачи пароля пользователю вызывается метод savePasses , Google Wallet Android SDK автоматически подписывает ваш JWT с помощью отпечатка SHA-1 вашего ключа подписи приложения, который вы указали в бизнес-консоли Google Wallet . Альтернативно вы также можете выдать пропуск, используя ранее подписанный JWT, используя метод savePassesJwt Android SDK.
Дополнительную информацию см. в разделе Выдача пропусков с помощью Android SDK .
