JSON Web Token（JWT）の操作

JSON Web Token は、情報を JSON オブジェクトとして安全に転送するために一般的に使用されている業界標準です。Google Wallet API を使用する場合は、使用するパス オブジェクトの詳細を JWT（「ジョット」と発音）形式でパス インスタンスを作成し、Google Wallet API へのリクエストでその JWT を送信します。

JWT は、Google Wallet API に送信される前に共有シークレットで署名することで保護されます。Google Wallet REST API を使用している場合、署名シークレットは Google Cloud サービス アカウント キーです。Google ウォレット Android SDK を使用している場合、署名シークレットは Android アプリの SHA-1 フィンガープリントです。

JWT でパスをエンコードする

EventObject を作成したら、次のスニペットに示すように、payload.EventObjects 属性を含む無署名の JWT でラップします。

JSON

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

JWT の正しい形式について詳しくは、JWT リファレンスをご覧ください。

JWT に署名する

JWT は、Google Wallet API に送信される前に共有シークレットで署名することで保護されます。Google Wallet REST API を使用している場合、署名シークレットは Google Cloud サービス アカウント キーです。Google ウォレット Android SDK を使用している場合、署名シークレットは Android アプリの SHA-1 フィンガープリントです。

ウェブ、メール、SMS

JWT には、Google ウォレット ビジネス コンソールで承認された Google Cloud サービス アカウントに関連付けられているサービス アカウント キーを使用して署名する必要があります。Google Wallet API は、JWT 署名を検証して、これらのクレームを検証します。

JWT に署名するとトークンが生成されます。このトークンを使用して「Google ウォレットに追加」リンクを作成し、ユーザーにパスを発行できます。

Android アプリ

savePasses メソッドが呼び出されてユーザーにパスを発行すると、Google ウォレット Android SDK は、Google ウォレット ビジネス コンソールで指定したアプリ署名鍵の SHA-1 フィンガープリントを使用して JWT を自動的に署名します。または、Android SDK の savePassesJwt メソッドを使用して、以前に署名した JWT を使用してパスを発行することもできます。

注: Android アプリでは、ウェブ、メール、SMS で説明した方法も使用できますが、Android SDK を使用することをおすすめします。

詳しくは、Android SDK を使用したパスの発行をご覧ください。
