JSON Web Tokens (JWT) के साथ काम करना

JSON वेब टोकन, आम तौर पर इस्तेमाल किए जाने वाले इंडस्ट्री स्टैंडर्ड हैं. इनका इस्तेमाल, JSON ऑब्जेक्ट के तौर पर सुरक्षित तरीके से जानकारी ट्रांसफ़र करने के लिए किया जाता है. Google Wallet API का इस्तेमाल करते समय, उस पास ऑब्जेक्ट की जानकारी को कोड में बदला जाता है जिसका इस्तेमाल आपको JWT (उच्चारण "jot") फ़ॉर्मैट में पास इंस्टेंस बनाने के लिए करना है. इसके बाद, उस JWT को Google Wallet API को अनुरोध में भेजा जाता है.

JWT को Google Wallet API पर भेजने से पहले, शेयर किए गए सीक्रेट टोकन से साइन करके सुरक्षित रखा जाता है. अगर Google Wallet REST API का इस्तेमाल किया जा रहा है, तो Google Cloud सेवा खाते की कुंजी को साइनिंग सीक्रेट रखी जाएगी. अगर Google Wallet Android SDK का इस्तेमाल किया जा रहा है, तो आपके Android ऐप्लिकेशन का साइनिंग सीक्रेट SHA-1 फ़िंगरप्रिंट होगा.

किसी पास को JWT में एन्कोड करें

LoyaltyObject बनाने के बाद, इसे payload.LoyaltyObjects एट्रिब्यूट की मदद से, साइन नहीं किए गए JWT के साथ रैप करें, जैसा कि इस स्निपेट में दिखाया गया है:

JSON

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

JWT के सही फ़ॉर्मैट के बारे में ज़्यादा जानकारी पाने के लिए, JWT का रेफ़रंस देखें.

JWT साइन करें

वेब, ईमेल, और एसएमएस

JWT में, Google Cloud Business Console में अनुमति दिए गए Google Cloud सेवा खाते से जुड़ी सेवा खाता कुंजी का इस्तेमाल करके, साइन किया जाना चाहिए. Google Wallet API, JWT हस्ताक्षर की पुष्टि करके इन दावों की पुष्टि करेगा.

JWT पर हस्ताक्षर करने से एक टोकन जनरेट होगा. इस टोकन का इस्तेमाल, 'Add to Google Wallet' बनाने के लिए किया जा सकेगा लिंक दें, जिसका इस्तेमाल करके उपयोगकर्ता को पास जारी किया जा सकता है:

Android ऐप्लिकेशन

जब किसी व्यक्ति को पास जारी करने के लिए savePasses तरीके का इस्तेमाल किया जाता है, तो Google Wallet का Android SDK टूल आपके JWT को, ऐप्लिकेशन साइनिंग पासकोड के SHA-1 फ़िंगरप्रिंट से अपने-आप साइन कर देता है, जिसे आपने Google Wallet Business Console में उपलब्ध कराया है. इसके अलावा, Android SDK के savePassesJwt तरीके का इस्तेमाल करके, पहले साइन किए गए JWT का इस्तेमाल करके भी पास जारी किया जा सकता है.

ज़्यादा जानकारी के लिए, Android SDK टूल से पास जारी करना लेख पढ़ें.
