Bekerja dengan Token Web JSON (JWT)

Token Web JSON adalah standar industri yang umum digunakan untuk mentransfer informasi dengan aman sebagai objek JSON. Saat menggunakan Google Wallet API, Anda mengenkode detail Objek Kartu yang ingin Anda gunakan untuk membuat instance kartu dalam format JWT (diucapkan "jot"), lalu mengirimkan JWT tersebut dalam permintaan ke Google Wallet API.

JWT dijaga keamanannya dengan menandatanganinya menggunakan rahasia bersama sebelum dikirim ke Google Wallet API. Jika Anda menggunakan Google Wallet REST API, rahasia penandatanganannya adalah kunci akun layanan Google Cloud Anda. Jika Anda menggunakan Google Wallet Android SDK, rahasia penandatanganannya adalah sidik jari SHA-1 untuk aplikasi Android Anda.

Mengenkode kartu di JWT

Saat FlightObject dibuat, gabungkan dengan JWT yang tidak ditandatangani dengan atribut payload.FlightObjects, seperti ditunjukkan dalam cuplikan berikut:

JSON

{
  "iss": "OWNER_EMAIL_ADDRESS",
  "aud": "google",
  "typ": "savetowallet",
  "iat": "UNIX_TIME",
  "origins": [],
  "payload": {
      "flightObjects": [ NEW_OBJECT ]
  }
}

Untuk informasi selengkapnya tentang format JWT yang diharapkan, lihat referensi JWT.

Menandatangani JWT

Web, email, dan SMS

JWT harus ditandatangani menggunakan kunci akun layanan yang terkait dengan akun layanan Google Cloud yang Anda beri otorisasi di Konsol Bisnis Google Wallet. Google Wallet API akan memvalidasi klaim ini dengan memverifikasi tanda tangan JWT.

Menandatangani JWT akan menghasilkan token yang dapat digunakan untuk membuat 'Tambahkan ke Google Wallet' link yang dapat digunakan untuk memberikan kartu kepada pengguna:

Aplikasi Android

Saat metode savePasses dipanggil untuk memberikan kartu kepada pengguna, Google Wallet Android SDK akan otomatis menandatangani JWT Anda dengan sidik jari SHA-1 dari kunci penandatanganan aplikasi yang Anda berikan di Konsol Bisnis Google Wallet. Atau, Anda juga dapat memberikan kartu menggunakan JWT yang telah ditandatangani sebelumnya menggunakan metode savePassesJwt Android SDK.

Untuk mengetahui informasi selengkapnya, lihat Menerbitkan kartu dengan Android SDK.
