JSON Web Tokens เป็นมาตรฐานอุตสาหกรรมที่ใช้กันโดยทั่วไปสำหรับการโอนข้อมูลเป็นออบเจ็กต์ JSON อย่างปลอดภัย เมื่อใช้ Google Wallet API คุณจะต้องเข้ารหัสรายละเอียดของออบเจ็กต์บัตรที่ต้องการใช้สร้างอินสแตนซ์บัตรในรูปแบบ JWT (อ่านว่า "jot") แล้วส่ง JWT นั้นในคำขอไปยัง Google Wallet API
JWT จะได้รับการรักษาความปลอดภัยโดยการลงนามด้วยข้อมูลลับที่ใช้ร่วมกันก่อนที่จะส่งไปยัง Google Wallet API หากคุณใช้ Google Wallet REST API ข้อมูลลับในการลงชื่อเข้าใช้คือคีย์บัญชีบริการ Google Cloud หากคุณใช้ Google Wallet Android SDK ข้อมูลลับในการรับรองคือลายนิ้วมือ SHA-1 สำหรับแอป Android
เข้ารหัสบัตรใน JWT
เมื่อสร้าง TransitObject แล้ว ให้รวม JWT ที่ไม่มีการรับรองด้วยแอตทริบิวต์ payload.TransitObjects ดังที่แสดงในข้อมูลโค้ดต่อไปนี้
JSON
{
"iss": "OWNER_EMAIL_ADDRESS",
"aud": "google",
"typ": "savetowallet",
"iat": "UNIX_TIME",
"origins": [],
"payload": {
"transitObjects": [ NEW_OBJECT ]
}
}ดูข้อมูลเพิ่มเติมเกี่ยวกับรูปแบบที่ต้องการของ JWT ได้ที่ข้อมูลอ้างอิงของ JWT
ลงนามใน JWT
JWT จะได้รับการรักษาความปลอดภัยโดยการลงนามด้วยข้อมูลลับที่ใช้ร่วมกันก่อนที่จะส่งไปยัง Google Wallet API หากคุณใช้ Google Wallet REST API ข้อมูลลับในการลงชื่อเข้าใช้คือคีย์บัญชีบริการ Google Cloud หากคุณใช้ Google Wallet Android SDK ข้อมูลลับในการรับรองคือลายนิ้วมือ SHA-1 สำหรับแอป Android
เว็บ อีเมล และ SMS
JWT ต้องลงนามโดยใช้คีย์บัญชีบริการที่เชื่อมโยงกับบัญชีบริการ Google Cloud ที่คุณให้สิทธิ์ในคอนโซลธุรกิจของ Google Wallet Google Wallet API จะตรวจสอบการอ้างสิทธิ์เหล่านี้ด้วยการยืนยันลายเซ็น JWT
การลงนามใน JWT จะสร้างโทเค็นที่นำไปใช้สร้าง "Add to Google Wallet" ได้ ลิงก์ที่ใช้ออกบัตรให้กับผู้ใช้ได้

แอป Android
เมื่อมีการเรียกใช้เมธอด savePasses เพื่อออกบัตรให้กับผู้ใช้ Google Wallet Android SDK จะลงนาม JWT โดยอัตโนมัติด้วยลายนิ้วมือ SHA-1 ของคีย์ App Signing ที่คุณระบุไว้ใน Google Wallet Business Console หรือคุณอาจออกบัตรโดยใช้ JWT ที่ลงนามไว้ก่อนหน้านี้โดยใช้เมธอด savePassesJwt ของ Android SDK ก็ได้
