Zapisywanie kart w Google Pay

Przypadki użycia są takie same we wszystkich kategoriach kart. Na przykład wszystkie karty lojalnościowe, karty podarunkowe, oferty specjalne, bilety na wydarzenia, lotnicze karty pokładowe i bilety na przejazdy można dodać do aplikacji Google Pay na kilka sposobów. Aby dowiedzieć się więcej, wybierz jedną z tych metod:

Dodanie przycisku na stronie

Dodaj przycisk Zapisz w Google Pay w swojej witrynie, aby umożliwić użytkownikom zapisywanie w aplikacji Google Pay kart lojalnościowych, kart podarunkowych, ofert specjalnych, biletów na wydarzenia, lotniczych kart pokładowych i biletów na przejazdy.

Gdy użytkownik kliknie ten przycisk, na serwery Google zostanie wysłany token sieciowy JSON (JWT) jego karty lub biletu. Na serwerach Google na podstawie tokena JWT zostanie utworzony odpowiedni zasób Object, który zostanie połączony z kontem użytkownika.

Aby zintegrować przycisk Zapisz w Google Pay ze swoją witryną, wykonaj 3 czynności:

  1. Określ Class rozszerzeń obiektów.
  2. Utwórz token JWT reprezentujący Object.
  3. Dodaj przycisk Zapisz w Google Pay do swojej strony.

Pokazane kroki dotyczą kart lojalnościowych, ale są takie same w przypadku wszystkich kart.

1. Określ klasy rozszerzeń obiektów

Najpierw określ LoyaltyClass. Aby wstawić LoyaltyClass, wyślij żądanie POST do tego identyfikatora URI REST:

https://walletobjects.googleapis.com/walletobjects/v1/loyaltyClass

Aby włączyć ścisłą analizę błędów i wykrywać dodatkowe błędy, takie jak powtarzające się pola identyfikatorów, dodaj parametr strict=true do identyfikatora URI REST, jak w tym przykładowym identyfikatorze URI:

https://walletobjects.googleapis.com/walletobjects/v1/loyaltyClass?strict=true

Poniższy przykład przedstawia zasób JSON reprezentujący LoyaltyClass. Należy go wysłać w treści żądania POST. Poniżej znajdziesz przykładowy kod pokazujący, jak określić i wstawić LoyaltyClass.

Zakoduj LoyaltyObject jako token JWT za pomocą klucza prywatnego konta usługi OAuth 2.0. Poniżej znajdziesz fragmenty pokazujące, jak zakodować token JWT w różnych językach. Karta protokołu zawiera niezakodowany token JWT. Objaśnienia pól tokena JWT znajdziesz w opisie tokena JWT Google Pay API for Passes.

Bezpieczna długość zakodowanego tokena JWT to 1800 znaków. Tokeny JWT nie powinny przekraczać tej długości. Jeśli długość przekroczy 1800 znaków, zapis nie będzie możliwy, ponieważ token zostanie przycięty w przeglądarkach. Obiekty zakodowane w tokenach JWT powinny być małe i zawierać tylko dane dotyczące użytkownika. Utwórz klasę obiektu przed tokenem JWT, aby zapisać w niej większość danych. Jeśli obiekt przekracza limit, spróbuj utworzyć go za pomocą interfejsu API REST i wysłać w tokenie JWT tylko identyfikator obiektu.

3. Dodaj przycisk Zapisz w Google Pay

Dodaj ten skrypt do strony, na której chcesz wyświetlić przycisk Zapisz w Google Pay:

<script src="https://apis.google.com/js/platform.js" type="text/javascript"></script>

Potem wstaw tag przestrzeni nazw g:savetoandroidpay, który określa miejsce i atrybuty przycisku Zapisz w Google Pay. Dodaj wcześniej utworzony token JWT.

<g:savetoandroidpay jwt="{jwt_generated}" onsuccess="successHandler"
onfailure="failureHandler" size="small" theme="light" ></g:savetoandroidpay>

Przycisk Zapisz w Google Pay powinien być widoczny na Twojej stronie.

Więcej informacji o przycisku JavaScript na stronie znajdziesz w dokumentacji dotyczącej interfejsu API podczas używania Google Pay API for Passes na stronach internetowych.
