経由地のあるフライト情報を追加する

飛行機で移動する場合、目的地に直行するのではなく、複数の場所を経由することも少なくありません。航空会社は、その旅程の区間ごとに 1 つの搭乗券を発券します。Google Wallet API は、区間ごとに個別の FlightObject インスタンスを使用することでこの処理をサポートします。

たとえば、SFO から LAX 経由で TPE まで行く乗客が 2 人いる場合、2 つの FlightClass インスタンス(1 人あたり 1 つ)と 4 つの FlightObject インスタンス(1 人あたり 2 つ)を使用します。

搭乗者名 FlightClass A(SFO -> LAX) FlightClass B(LAX -> TPE)
J. Smith FlightObjectid_jsmith_1 FlightObjectid_jsmith_2
J. Doe FlightObjectid_jdoe_1 FlightObjectid_jdoe_2

これらのフィールドは、物理的な搭乗券と同じ値を反映します。

ユーザーが複数のチケットを同時に購入するシナリオには次のようなものがあります。

  • 複数のフライト
  • 乗り継ぎの便のある移動
  • 家族分の購入

このような状況では、ユーザーが多くの搭乗券を Google ウォレット アプリに同時に追加できるようにすると便利です。JSON Web Token(JWT)で複数のオブジェクトまたはクラスを定義し、それらを使用して [Google ウォレットに追加] ボタンまたはリンクを作成できます。ユーザーがボタンをクリックすると、定義されたすべてのパスがユーザーのデバイスに同時に追加されます。

署名する JWT で、payload プロパティの flightClasses 配列と flightObjects 配列にそれぞれパスクラスとパス オブジェクトを含めます。次の例では、これを行う 2 つの方法を示します。

複数のパスの UI 表現の詳細については、複数の搭乗券をグループ化するをご覧ください。

既存のクラスとオブジェクト

この例では、事前に作成されたクラスとオブジェクトを使用し、それぞれの ID のみが必要です。パス オブジェクトの classId プロパティは省略可能です。ここでは、説明のために使用しています。

{
    "aud": "google",
    "origins": [],
    "iss": "your_iam_account@appspot.gserviceaccount.com",
    "iat": 1534891254,
    "typ": "savetowallet",
    "payload": {
        "flightObjects": [
            {
                "classId": "issuerId.flightClassSuffix",
                "id": "issuerId.flightObjectSuffix_01"
            },
            {
                "classId": "issuerId.flightClassSuffix",
                "id": "issuerId.flightObjectSuffix_02"
            }
        ]
    }
}

新しいクラスとオブジェクトを作成する

この例では、1 つのクラスと複数の子オブジェクトを定義します。クラスとオブジェクトの両方が Google ウォレットによって作成されるのは、ユーザーが [Google ウォレットに追加] リンクをクリックしてデバイスにパスを追加した場合のみです。

                "reservationInfo": {
                    "confirmationCode": "ABC123"
                }
            },
            {

            }
        ]
    }
}
