Mit JSON-Webtokens (JWT) arbeiten

JSON Web Tokens sind ein gängiger Branchenstandard für die sichere Übertragung von Informationen als JSON-Objekt. Wenn du die Google Wallet API verwendest, codieren Sie die Details des Karten-/Ticketobjekts, das Sie zum Erstellen einer Karten-/Ticketinstanz im JWT-Format (ausgesprochen „jot“) verwenden möchten, und senden dieses JWT dann in einer Anfrage an die Google Wallet API.

JWTs werden sicher aufbewahrt, indem sie mit einem gemeinsamen Secret signiert werden, bevor sie an die Google Wallet API gesendet werden. Wenn du die Google Wallet REST API verwendest, ist das Signatur-Secret dein Google Cloud-Dienstkontoschlüssel. Wenn Sie das Google Wallet Android SDK verwenden, ist das Signatur-Secret der SHA-1-Fingerabdruck für Ihre Android-App.

Karte/Ticket in einem JWT codieren

Wenn das EventObject erstellt wird, musst du es mit einem unsignierten JWT mit dem Attribut payload.EventObjects versehen, wie im folgenden Snippet gezeigt:

JSON

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

Weitere Informationen zum erwarteten Format von JWTs findest du in der JWT-Referenz.

JWT signieren

Web, E-Mail und SMS

Das JWT muss mit dem Dienstkontoschlüssel signiert werden, der mit dem Google Cloud-Dienstkonto verknüpft ist, das Sie in der Google Wallet Business Console autorisiert haben. Die Google Wallet API validiert diese Anforderungen durch Verifizierung der JWT-Signatur.

Durch das Signieren des JWT wird ein Token erzeugt, mit dem dann ein „Zu Google Wallet hinzufügen“ erstellt werden kann. Link, über den die Karte bzw. das Ticket an einen Nutzer ausgestellt werden kann:

Android-Apps

Wenn die Methode savePasses aufgerufen wird, um eine Karte bzw. ein Ticket an einen Nutzer auszustellen, signiert das Google Wallet Android SDK dein JWT automatisch mit dem SHA-1-Fingerabdruck deines App-Signaturschlüssels, den du in der Google Wallet Business Console angegeben hast. Alternativ kannst du die Karte bzw. das Ticket auch mithilfe eines zuvor signierten JWT mit der Methode savePassesJwt des Android SDK ausstellen.

Weitere Informationen findest du unter Karten/Tickets mit dem Android SDK ausgeben.
